Rain moving in.....update on the forecast

Good afternoon bloggers,

It is going to rain today!  Good news for some of your lawns.  A disturbance that formed last night is slowly spinning by today.  Rainfall amount will vary from 1/10th of an inch to possibly an inch of rain in a few spots.  This is a rapidly growing area of rain and it should last a few hours , but then move off to the south and east and end.  So, it is going to end up being a cooler and wet August day.

There seems to be a lot of frustration out there with the forecast changing with each model run.  There has been a good reason for these changes.  The models have been all over the place, and predicting the movement of an upper low that was in Canada, turning south, and how it would affect us is one of the toughest forecasts.  Here is the latest, and finally I am extremely confident in this change to the forecast.  Look below at the forecast for 1 PM Friday:

This is the 500 mb level, or around 18,000 feet up in the atmosphere.  The reason most forecasts had rain in there every day is because of an upper level circulation that was forecast to develop over northeast Kansas today.  It is NOT happening as you can see in the 30 hour forecast above.  Today's disturbance will move south of the area tonight.  We will be in north flow aloft with no hint of that spin-off (as I called it last night on the 1 AM newscast).  This will allow high pressure at the surface to build in, lowering our dewpoints, and not only ending the threat of rain by Friday or Saturday, but bringing us the exact opposite......spectacular summer weather.  The upper low is now forecast to be way back over Wyoming and still dropping southwest. 

We will be tracking these developments on the air tonight at 5, 6, and midnight (after the Olympics) on NBC Action News.  At least it looks like we will get some rain today.  It has been a dry month of August, so let's soak it in.  Have a good afternoon.  We will try to answer your questions and provide therapy for the emotional weather ride we are all going through.

Grif is the captain of this Ultimate Frisbee team.  They are playing in a tournament this weekend, and Stormy and I will go out there and support them.  Here is a quote from Grif:  "I thought of using LRC as our team name a couple weeks before the league started when you posted a picture on your blog of someone wearing the LRC shirt from zazzle.com... I thought that a team of people running around in those shirts would be pretty awesome.  Attached you should find a picture of our fine team - in the picture you can see everyone showing our patented hand signal... the "L" (for Lezak obviously)."  Here is the picture of the team.  Good luck Saturday guys!

No complaints here Gary. Yeah, we need the rain but not a washout of the weekend. I think we are doing ok, in parts of KCK anyway. I have been mowing every 3-4 days since May and my lawn is still green with no help from me.  As for the critics' at least you attempt a forecast and make changes. Others like to issue generic forecasts ("chance of rain today") and then boldy make a prediction when the system is on top of us.

the discussion from the NWS seems to be coming to fruition at this point... once again its too early to know for sure, but i think we will get several hours of rain beyond today-i just dont think it will amount to a lot...showery:

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
640 AM CDT THU AUG 14 2008

.DISCUSSION...
/312 AM CDT THU AUG 14 2008/


SEVERAL FEATURES OF INTEREST FOR THIS FORECAST.


THE STRONGER WAVE IN WYOMING IS OF MORE INTEREST. MODELS ARE COMING
TOGETHER ON A SOLUTION OF HAVING A ONE TWO PUNCH FOR THE CENTRAL
PART OF THE COUNTRY OVER THE NEXT WEEK...WITH THE LEADING WYOMING
WAVE DEEPENING SLIGHTLY AS IT IS KICKED SOUTHEAST AHEAD OF A MUCH
MORE WOUND UP SHORT WAVE DROPPING IN FROM SOUTH CENTRAL CANADA. THIS
SECONDARY WAVE IS EXPECTED TO CONTINUE TO DROP TO THE SOUTH AND CUT
OFF OVER SOUTHERN WYOMING AND NORTHERN COLORADO...WHILE THE INITIAL
WAVE...LOSING ANY PUSH FROM THE MORE WESTERN WAVE...CUTS OFF OVER
NORTHEAST KANSAS AND SOUTHEAST NEBRASKA BY FRIDAY EVENING.

DURING THE DAY TODAY...AS THE FIRST WAVE MOVES FROM WYOMING INTO
NEBRASKA AND KANSAS...EXPECTING A WARM FRONT TO SET UP ACROSS
NORTHERN MISSOURI FEEDING BACK TO LOW PRESSURE OVER SOUTHWEST
KANSAS. WITH THE SHORT WAVE MOVING INTO EASTERN KANSAS TOWARD 06Z
TONIGHT...THE SURFACE WAVE SHOULD ALSO BE MOVING INTO EASTERN KANSAS
WITH A WARM FRONT BISECTING WEST TO EAST ACROSS THE CWFA. EXPECT
SHOWERS AND THUNDERSTORMS TO BE DEVELOPING ALONG THIS FRONTAL
BOUNDARY...WITH THE POTENTIAL OF SOME TRAINING EFFECT OF THE
RAIN...PRODUCING HEAVIER RAINFALL. THE QUESTION IS EXACTLY WHERE THE
BOUNDARY WILL BE SETTING UP...WITH THE MORE LIKELY REGION BEING
SOMEWHERE BETWEEN KANSAS CITY AND ST JOSEPH. AS THE DAY PROGRESSES
ON FRIDAY...THE HEAVY RAIN BAND MAY ROTATE FURTHER TO THE NORTH AS
THE UPPER WAVE BECOMES CUT OFF...AND THE SURFACE WAVE TAKES ON A
MORE INVERTED TROUGH LOOK TO IT. THUS THINK A BAND OF HEAVIER RAIN
WILL CONTINUE TO FEED ACROSS PORTIONS OF THE CWFA FRIDAY AFTERNOON
AND FRIDAY EVENING...BUT THE BIG QUESTION IS WHETHER THIS WILL
PRODUCE REPEATED ROUNDS OVER THE SAME AREA...OR SHIFT ENOUGH TO
PREVENT FLOODING FROM BECOMING A PROBLEM. WILL NOT POST ANY KIND OF
A WATCH AT THIS POINT AS THIS IS STILL OVER 24 HOURS OUT...AND MUCH
UNCERTAINTY REMAINS OF EXACTLY WHAT AREAS COULD BE IMPACTED.

THIS CUT OFF UPPER LOW IN NORTHEAST KANSAS SHOULD GRADUALLY FILL AND
WEAKEN AS THE STRONGER WESTERN WAVE OVER COLORADO SLOWLY SHIFTS TO
THE EAST THROUGH THE WEEKEND. BUT WITH THIS KANSAS CUTOFF REMAINING
IN THE REGION...PERIODS OF AT LEAST LIGHTER SHOWERS WILL BE
POSSIBLE...BOTH SATURDAY AND SUNDAY...WITH STRONGER STORMS EXPECTED
TO STAY TO THE SOUTHEAST OF THE FORECAST AREA...WHERE WARMER AIR AND
MORE UNSTABLE CONDITIONS SHOULD EXIST.

TEMPERATURES WILL REMAIN UNSEASONABLY COOL WITH THIS PATTERN...AS
QUITE A BIT OF CLOUDINESS AND EASTERLY WINDS WILL DOMINATE THROUGH
THE WEEKEND. FOR THE FIRST OF NEXT WEEK...WE WILL BE DEALING WITH
THE SECOND PART OF THIS ONE TWO PUNCH AS THE COLORADO WAVE SLOWLY
EMERGES INTO THE CENTRAL PLAINS ON MONDAY. A VERY WET PERIOD IS
GOING TO BE AFFECTING THE CWFA THROUGH AT LEAST MIDDLE OF NEXT WEEK.

what do you think, gary?

btw scott,

i know you hate the NAM...and i dont blame you.  the NAM really hurt my feelings last fall with the first potential ice storm that ended up being further north....errr.  not that i wanted an ice storm, but i wanted to be right....and i wasnt.

but, i have found that the NAM performs rather well in the fall time, and spring time for that matter.  it seems to do well with transitions.  and like gary said, its good for short term trending as well...but i like it for the fall especially.

Stormdog said:

Stormdog - Okay, with models "all over the place"  how do we buy the "latest solution" with such certainty.  The initialization of the last GFS run (which according to some, hasn't performed brilliantly lately in any case) has the upper low just crossing into Montana, then Swd essentially into Colorado before dying out - it really doesn't show much of a southwestward trend at all, if one wants to buy any models solution anyway.  And where was this disturbance spinning by today in the models - no one really forecast rain for today - it was Friday.  Bottom line I think is, throw out the computer models and look out the window.

Beyond the next day, they are useless, or worse than useless right now - back and forth, and it's just as useful to hang chicken entrails up in your door - if the blood doesn't congeal and runs down the carcass, then it's raining, if it congeals it is not.

Now THAT'S A FORECAST YOU (OR ANYONE) CAN REMEMBER!!!

Later,
Dog

---------------

Dog,

Experience!  We have always wondered, but not anymore.  The models have been all over the place, but now this solution is correct.  Dry this weekend.

Gary

Murph, for short range, I will take the RUC over the NAM anyday.  The RUC has not changed much in the last 5 runs.  

Gary - I will take that perfect forecast for Sat to the bank.  I will expect no rain in the viewing area.

Based on what I see, I see the ULL in Colorado trying to "reach out" if you will to troughing from the NE.  You can see that on the link below.

http://ruc.noaa.gov/disp2.cgi?/w3/rapb/plots_13km_dev/.//+sa5_p500mb+am+48

This would cause two things to happen.  One, it would set up a boundary layer between the cool dry northern air you describe, and the southern moist air.  It would also create a point of focus.  

This is mentioned above in the NWS discussion..

The second is I see the vorticity wanting to stretch out a bit through the boundary layer.  If so, this would allow each day to have rain chances as each little piece of energy that goes through the path to bring small complexes of storms.

No doubt this storm is tricky..but think the major models have made many look flip floppy right now.

-----------------

Scott,

And when it is nice on Saturday, I expect to hear back from you!

Good luck weather team..your feet are being held to fire on this one it sounds like. I am rooting for you, you are sticking with no rain this weekend no matter what....right?? Are the temps expected to rise any this weekend since rain is now out of the forecast? I was wanting to take the girls to the pool one last time this summer. There favorite pool closes on Sunday. Good luck!

Gary, I am not saying that parts of the viewing area will not have a nice Saturday.  I am saying that there will be a chance of rain as I don't see the high pressure getting here as quickly/strongly as you think.

If it does not rain anywhere in the viewing area on Saturday midnight to midnight, I will be the first to eat crow publically on this forum.

What will YOU do if it DOES rain somewhere in the viewing area on Saturday?  LOL

Ok not to bother you guys but we are supposed to have soccer tonight in Lees Summit is that still going to happen?

There will still be some showers around, hopefully they stay away from your area.  You can play soccer in the rain right?

I stayed up and watched the forecast at 1 AM....  Gary called for someone in the area to get six to seven inches over the next few days.  It's not going to happen.  The rain we got today will probably be the biggest event we get over the next week.  I wouldn't change your outdoor events. If it rains, it will probably be nothing more than a brief shower.  It won't be a washout.

BTW, I was down by Truman Lake this past weekend.  Some friends of mine are building a house in Montrose.  The building site had some rain but 26 miles to the ESE barely a sprinkle.

Kristi,

I meant 6 to 7 hundreths.  Everything changed as you can see in my blog today.

Gary its been raining pretty good in sedalia for bout 45 min. how long should it last. plus the temperature is absoultely amazing

DaveC said:

Gary said : The models have been all over the place, but now this solution is correct.  Dry this weekend.

I'm not saying I don't believe you, but I'm not sure I understand why you have even more confidence in this latest model run then say last night, or the night before last. I understand we are getting closer to the "event", but even that in itself sometimes means little.

--------------------

The reason I am now much more confident is because there is no evidence of that second upper low forming.  So, high pressure must take over at the surface, our dewpoints will drop and there will be almost no forcing for rain after Friday.  So, This is why my confidence level is very high, finally.  My lawn is not too happy about it though.

And, your confidence in our forecast will be growing too.  Everything is now falling into place for the dry scenario.

Is this weather pattern a hint that the possibility of a earlier than normal first snowfall?

Audra,

No, and I don't know when they will catch on, but it will be dry this weekend.

kcwxguy said:

In looking at Personal Weather Station data and at radar estimate rainfall amounts, it appears areas near Chillicothe have already recorded upwards of two inches of rain today.

Is Chillicothe in the viewing area?  LOL

In looking at the new model data [why do I even look with this storm?], Sat looks much drier.  I may start early eating crow early.

[I think there is enough crow all around for anyone else..LOL]

-------------

Scott,

This is why I said that our confidence level is high. It will be dry.  And, it is amazing that those areas in Livingston county had nearly 2 inches of rain today, in our viewing area.

I am sooo happy!!  It is around 70˚ and it has been sprinkling/ raining here (68th Terr. and Oak ) for a couple of hours off and on!! I have around 1/10th of an inch in my rain gauge at the moment.  I'm happy, my lawn is happy, and my flowers are happy!  My dog is not happy.  He does not like rain.  Oh well, 3 out of 4 is not bad!!  Lovin' this weather!  Dea

radman22 said:

I went with the under 2"   So no crow for me  :)  

Gary nailed this before everyone else.   Did some flip flopping, but everyone did with this storm.   He is sticking to his guns now and if the metro gets more than 1" widespread  from even 1 event, he will take the hit.    

I am glad for a nice cool dry weekend.   Go back and find another stretch like this in mid August.   No way we would have 5-7 days like this!!!!   Will we hit 90 again at KCI?    LOL

------------------

Yes, I think we will hit 90 degrees.  And, I can't even imagine 1 inch of rain in the next four days.  Thanks for noticing the correct forecast change before everyone else.  Are we right this time?  YES!  But, my lawn is still thirsty.

Oh, Gary, I have to hand it to you!  You are the best meteorologist, and you are the most fantastic critter person.  I so thoroughly enjoyed the video segment of Stormy, Breezy, and your two house guests.  Congratulations on enjoying life so much---it’s contagious---I’m sitting at the computer with a big smile on my face!

That “rejuvenated” me this evening!

I am so glad you enjoyed the segment with Breezy, Stormy, Stuey and Slick.  I am showing it again tonight at midnight or 1 AM whenever we are on.  It is just amazing watching Breezy and Stuey getting along so well.

Gary, another thought just occurred to me.  How was the behaviour of the 4 of them in your car coming to the studio?  You are also very brave!

By the way, we did get to enjoy a very nice kind of rain in Leavenworth this afternoon.  Just my kind:  easy-does-it kind of rain, no storminess, mild temperature.  It's been a beautiful day!

They ride well together in the car, but the video was done at my house!  I just watched it again.

currently sitting at a coolish 63 degrees here at the fort...may want to lower the projected low for KCI tonight...we have already hit it.

We were just outside.  The low will likely dip into the 50s.  Do you think dense fog will form?

im getting a feeling of deja vu. those storms are just about to enter osceola, ia, just like last night moving soutward. i wouldnt be surprised at all to see them make it down here just like last night.

I won't ignore them tonight, I promise. But, they will likely fall apart soon.  We will see.

lezakEF5 said:

Hey Gary, when you told Dwight there is no chance with the rain moving south in Iowa, are you talking about Kansas City. Is there a chance the rain may make far south enough to affect areas around Marceline to Chillicothe?

Thanks,

Alex

Alex,

I wouldn't be surprised if it did make it close to you, but I still doubt it will.

Gary

August 14, 2008 10:44 PM
 

pvt_murphy said:

yes, 91% relative humidity.  no doubt it should be foggy in the usual spots.

Murph,

I just went outside and saw some low fog forming here, so there has to be patches at least by morning.

Randy Cooper said:

hey alex,
i dont know about gary, but im gonna say yes. the radar just looks exactly like it did last night. i predict we will get the cells around 2 or 3 this morning. they are only moving 25 to 30 mph.

Randy,

Let's see if they make it across the Iowa border.

lezakEF5 said:

Randy,
I agree, the radar does look very similar to last night, but lets do what Gary said, and wait to see if they make it across the border. I am still thinking they will make it down here, or very close. They are getting offly close to the border.

We'll see what happens.

Gary...BTW, my guage had 0.70 inches today.

looks like its gonna split around us and the one to the west will head toward st joe / kansas city area if it holds together. we miss out this time. but thats ok with the rain we got last night and this morning here in chillicothe, we got probably around 4 inches possibly 4 and a half total rainfall the last 24 hours,
