New Areas Of Thunderstorms...July 28, 2009

Watch NBC Action News in HD for Kansas City's most accurate forecast!

Good morning everyone,

Thunderstorms on Monday evening were quite fascinating to watch develop, grow, and drift east and northeast.  There was a complex of thunderstorms during the afternoon that formed near Topeka which produced yet another microburst with some damage, but no injuries.  We have had a summer of microbursts, but fortunately that was the only isolated one on Monday. Those thunderstrorms never quite fell apart and ended up redevloping a couple of times as they drifted east.  Right around sunset thunderstorms developed over the Kansas City metro area dumping very heavy rain and producing some rather vivid lightning.  Here is a picture taken by Skylar Vance, one of our bloggers:

The models are finally catching onto what I showed last night on our weathercasts at 6 and 10 PM.  There is a more well defined upper level disturbance moving our way from the western plains and it is directly aimed at our local region.  Look below at the forecast map valid at 7 PM tonight from the 06z GFS:

As this wave approaches thunderstorms may continue to form in the diffluence ahead of the wave.  There is a weak wind shift line also moving through.  Our forecast high of 89 degrees yesterday was our 11th day in a row within 3 degrees as we hit it on the nose.  Now, will the streak continue today?  We had 77 for the high, but changed it to 80 degrees on our 10 PM newscast.  It will likely depend on what happens with this developing morning complex of thunderstorms taking aim on the KC metro area.

Have a great morning and we will try to update the blog after the new data comes in.

It's 5:17 am here and pouring cats and dogs.  The thunder woke me up and I was surprised to see one little cell right over us.  After the sun is up I'll check the rain gauge to see how much this cell rained guys.  Guess I can't mow the yard until tomorrow now.

Rain always ruins everything....seems it rains here most everyday.  Neice and nephew are visiting and we have tickets for Starlight tonight, I'm guessing I better come up with a plan B.  It's almost impossible to make outdoor plans in this area, especially Paola as it truly does seem to rain most everyday.  
Always soggy in Paola and missing the 100+ degree days with sunshine......

NW Lawrence picked up 0.91" through 7:00 AM with another thunderstorm just to the west.  I will report the total for this complex tomorrow morning.

Thanks, Larry, have a great day and get us your final total tomorrow.

Good Morning Gary!

We received a whopping .84 at 115th and Donahoo in Kansas City, Kansas last night from the storms. Nothing like what they received on the eastern end of KCK with the high water rescue report that I saw at 14th and Washington. The storms last night were incredible to watch develop all around western Wyandotte County. We didn’t receive any rainfall here at my place Monday evening. Did sit outside last night and their was vivid lightning from the storms that were in Jackson County around 9:30. Also, I mentioned this in the blog last night but the storm near Lynn County around 6 or so had a nice ring that came out from it on the radar images. Any reports of wind damage as that storm collapsed? At any rate, looking forward to getting some more rainfall today. All this moisture here since June has caused my pumpkin plant vines to grow about 17 feet in every direction. Incredible year for them!

Dry as a bone here.  Zilch in the rain gauge, I really need some rain, or it's dragging the hoses tonight!

There ya go Gary, MW Lawrence got 0.91" as Larry said by 7AM and here in McLouth we only got 0.56" in the same time.  But now after another round we are up to 0.97" and there is more just to my south and west a mile away.  Your blog entry has 3:21AM stamped on it.  Either you were up late or the storms got ya up early.  Hope the storms don't upset the puppies very much.  Also, you have been staying close to home and we have had weather.  So much for the "dog days" of summer.  I understand we may need jackets late this week, is that right?

Whe I woke up there was a storm just NNE of me and it has some slight bioling of the clouds, not sure you could call them mammatus yet though.

Last night was probably the noisiest I've ever heard it at my house without us receiving a drop of rain (near downtown O.P.). Storms were raging close by, many loud thunderclaps, but no rain until this morning.

juba said:

Same here RDub, except we had one very breif heavy downpoor here. I have a question though, my inbox for this place say I have one unread email but I've gone though all mine and nothing is new.

I'm still trying to learn about weather & I am curious about why we've had so many microbursts this summer.  I'd never heard of a microburst until the Raintree Lake one about 12 years ago & now you hear about them all the time.  Have these been happening all along (I assume so) but weren't callled microbursts?  Thanks!

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

A microburst is basically straight line winds, as opposed to circulating winds associated with tornadoes.  They happen all of the time, but this summer we are consistently in the zone near the cap where these thunderstorms are producing microbursts.  It is related to the LRC but on the more meso or micro scale and I doubt it is like this next year over our local area.

Was out reading on our balcony last night when distant thunder and a cool breeze warned of impending rain. No sooner did I go to head inside than a LOUD clap of thunder made me jump a mile high. We had a lot of close lightning in Mission last night. The dog did not enjoy it at all! But it was nice to hear a summer thunderstorm after it being dry for a while.

nikjo said:

Can you explain how the microbursts are related to the LRC?  
July 28, 2009 10:28 AM
 

nikjo said:

It would be helpful if you could go through each cycle of your proposed LRC to demonstrate the correlation from day to day within the cycle, both on the surface and at 500mb.  Seems like this should already be done, if you are claiming this discovery.  I understand you say there are variations from cycle to cycle, so to me, by pure definition, it is not a cycle.  It is a weather pattern, which have been obvious to any weather watcher.

Please push more of this rain south to N. Overland Park.  We need more than the measly 1/10th of an inch we got this morning.

Its been amazing how there seems to be a line of all or nothing...north of I-70 seems to have had some beneficial rain and south not nearly as much and seems to be staying on this same course all morning...I'm getting frustrated...Gary do you see any indication of this moving more SE otherwise I'm going to have to water my lawn tonight.

The blue clouds moved north of us this morning and have been inching a little closer in my mind. Checking...Yes they are coming closer. nikjo, the LRC often does fit right in place over the winter. Its like a repeating show of some sort but as the jet stream weakens the show slows down and that makes it change, but its still the same show. The LRC is a weather pattern I guess, it repeats. It has only spead back up recently scince for some reason the jet stream has reintensified more than usual for this time of year. And so were back to what it was in April. Maybe becasue its been cooler recently.
