CoCoRaHS, you can be a part of it!

Good morning bloggers,

Today we are going to talk about CoCoRaHS.  What is it?

From their website:

"CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network.  CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow).   By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, our aim is to provide the highest quality data for natural resource, education and research applications. We currently operate in many states across the country. If we are not in your state please drop us a line and let us know that you have an interest in participating.  This helps us know where a desire exists for the network and where to focus our future expansion efforts."

They are growing in observers across Kansas and Missouri.  Here is the link to their website:   http://www.cocorahs.org/

They encourage you to be involved:  The only requirements are an enthusiasm for watching and reporting weather conditions and a desire to learn more about how weather can effect and impact our lives.

So check it out, and let us know what you think.  Now, back to our weather situation today.  Look at the 7 AM surface map below:



The observation sites with just a circle and no wind barbs mean the wind is calm.  The pressure gradient continues to be very weak and there are many locations with almost no wind at all this morning at the surface.  This is the 7 AM surface map.  The higher humidity has had a hard time returning with not much wind to bring it back.  This is one of the reasons that the MCS (Mesoscale Convective System) activity has been tracking to our west this week.  A disturbance aloft will track near by tonight, and a light south wind should be enough to get our dewpoints back up to near 70 degrees by tonight. 

We will be tracking any developing thunderstorms on Live:ESP radar today and tonight.  Have a great day!

Gary

This dry weather is nice. There were some thunderstorms last night to the NNE of us here in Marceline. They had very neat cloud formations.

I like that website!

I'm ready for some more storms Gary, they don't have to be severe. If it doesn't storm tonight is this our last best bet for a while?

Good morning Gary- love the shirt - you do need something like that!

Excited to see the new weather page!  This weather has been absolutely beautiful..

With the weather patterns changing this time of year does it become more difficult to use the LRC for long range forecasting? Help me understand what is happening to the long term long waves now- are they breaking down? just trying to understand it all.

Thanks...JP

Hey Gary, quick question, what are the chances for rain around 6:30?  I've got a softball game and we haven't been able to play due to the rainy Thursdays!  Can't you move the rain to Friday?

Thanks!

Hey Hail,
You got an opinion on when it should start raining?

Becky,

Looks like the chance of rain increases as the afternoon wears on.

I am a contributor to CoCoRaHS and post every morning and encourage everyone else.  This effort is in part how models are developed.  The more accurate and interperated the data is the better the models will be.  This nice break due to the summer flow is nice and easy to live with.  Looks and feels great as long as we do not go into a drought.  The cool, wet weather has already destroyed the wheat and damaged the corn.  A drought will kill the corn and soybeans.  I think we all are already paying for the rough winter and spring enough at the grocery store and pump.  We still ned another good 5 days to dry out before the next rain event greater than 0.25".  The only ones enjoying the weather is the grass and bugs.

I would like to join this network.  Does anyone know if you can buy one of these 'official' CoCoRaHS in this area or are they only available online?

CoCoRaHS program is very neat!  I just signed us up. I had heard Brett mention it before but had never checked it out. Great program to do as part of our homeschool!  Thanks for passing on the info Gary!  

nastyweather - you can buy the official gauge from them online.  WHen you fill out the application, it has link to purchase the gauge...$22 + shipping.

Ideally the thunderstorms hold off until about 11PM, because I have outdoor plans up until about then. Of course, right now 6-10PM, the absolute worst time it could storm, looks like the best window. Meaning, the game will probably get rained out. Down south, near Wichita, potential exists for a major severe weather outbreak. Unsure of a tornado threat, but lots of instability down in that direction.

I have been a member of CoCoRaHS for about two years now.  The Kansas CoCoRaHS coordinator sponsored a meeting last August in Lawrence for those members that could attend and invited the senior meterologist from the Topeka NWS and a number of his staff to attend.  The Kansas coordinator tries to have semi-annual meetings across the state to discuss CoCoRaHS, reporting responsibilities and to have a great discussion on weather.  At the last meeting, CoCoRaHS passed out snow boards (to measure the depth of the snow); discussed how to measure the core water value of the snow that was received; and passed out hail pads (which have beens used extensively this past spring/summer by those of us in Lawrence.

I will look for my local CoCoRaHS info and post the names and e-mail addresses (with their prior permission) if anyone is interested.  One of the coordinators is also located in Overland Park and attended the last meeting.

nastyweather...i just reread your post. Sorry I misuderstood your question. On the application it also said you could contact the director in your area to purchase a rain gauge.  The problem was I did not see an address for a director that was local to the KC metro.

Gary,
Thank you so much for doing a blog on CoCoRaHS. I think it is very important and needs more attention than it gets.

CoCoRaHS is a very neat network. I have been contributing to it for two years now, and I try to get my report in every morning. I encourage everyone who reads this blog to join, as the more people we can get, the better the program works.

We currently have no one reporting from LEAVENWORTH or WYANDOTTE or MIAMI or LINN counties in Kansas, so if you live in any of those counties, please sign up!! We need your help!

Dwxtracker said:

Nastyweather/KCFarris,

Every county has its own coordinator. If you do not want to purchase one online, then contact them for more information. I think several of the hardware stores in the area sell them, but I couldn't tell you which ones.

For Kansas: http://cocorahs.org/Content.aspx?page=coord_ks
For Missouri: http://cocorahs.org/Content.aspx?page=coord_mo
(There are only two for Missouri, I'm not sure why.)

No one in Linn does CoCoRaHS. Well then I will sign up. I love to report weather totals and all. I will get that done later today. Do they have things I can buy to help me cause I do not have a "weather station". I probably need better equipment than I have. COuld someone let me know.
Thanks

KCFarrisFamily said:

Thanks Dwx...on the app though it only lists the Regional coordinators as contacts for the rain gauge and none of those are local...sorry I was calling them directors but they are coordinators.  Its my understanding that you would still have to purchase the rain gauge even if you contact one of them, right?  Do you know if you have to be using the official rain gauge to participate or can you use your own?

We're in Wyandotte county and just signed up so YEA!  We will be counted for!!

Gary, you mentioned that dew points would need to be around 70 here for our chance to increase significantly for rain this afternoon. But looking at the NOAA site, dew points where the storms are  tracking across Nebraska and western Kansas right now are the same as they are here (60) or even lower.
Why the difference on dew points inducing more rain out west when  they are the same for both regions today?

******************

There is a disturbance over NE & IA that is triggering the storms.  The dew points around our viewing area are now in the 63-65 degree range.  So they are slowly climbing.  Our best rain chance heads in later this afternoon.

Gary, how much rain are you expecting to fall?

To follow up with A dogg - "Gary, how much rain are you expecting to fall?"

I would like this to be specific to my backyard and with variance of only .01 inches.

Thanks.

I'm back! Been back for a couple of days, trying to get rid of post vacation stress, in other words getting back to the normal routine. In the last two wks, olathe north hs has gotten 6.93" of rain!! I also got to travel with my grandparents to Branson,Mo where I saw my family. Got a great sunset from Branson!!

haha very funny, I just want an estimated amount, like 1-3, im not one of those people who gets mad if hes wrong by .5 inches, I would just like a general idea

Depends on whether a heavy thunderstorm hits your neighborhood or not. If you live on the southside of town, you'll get more. I'd ballpark between a quarter and half an inch on average, but if the complex of thunderstorms over western Kansas turns dead east, we could get a gullywasher.

On his 10pm news forecast last night Gary showed Powercast projecting Lee's Summit to receive 4 inches of rain.  I know data may have changed by now, but I hope this is an instance where the computer is wrong!

KCFarris, (and Mamaof3)

Thanks for signing up!!!!!!!

Yes likely you will still have to buy one of the rain gauges, unless you are lucky. I actually met the person who helped start the whole program, Nolan Doesken, and he gave me one free. You probably won't be so lucky :P, but they're not that expensive, and they are really nice. They are much more accurate than electronic rain gauges when it comes to heavy rain. My electronic gauge can be as much as 30% off during heavy rain events.

Also, you can use one of your own, but they would rather that you have one of the 11" "official" gauges so that everyone has the same equipment.

Can anyone tell me what the updated forcast is for the rain?

Looks like we have a MD for the metro and points northwest.

kcwxguy said:

MCS events are nearly impossible for models to show well.  Especially inhouse commercial displays.

It should always be assumed that thunderstorms will be scattered and locally heavy in areas.

I could give that forecast everyday nearly in late Spring.  

Slow moving thunderstorm complexes can/do dump along of rain..but from a regional perspective, it is really only a small area being affected.
June 19, 2008 1:19 PM
 

Dwxtracker said:

New MD for areas metro northward. SPC says watch likely soon.

AREAS AFFECTED...ERN NEB...WRN IA...NW MO...NE KS
 
  CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
 
  VALID 191814Z - 191915Z
 
  A WW WILL BE NEEDED SOON.

Dwxtracker.....I am excited about being a part of it. Those fancy rain guages are on back order right now so I will have to rely on the one I have for now. Do you know how I can get my latitude/longitude readings for my rain guage placement? Is there a website that you can just plug in some numbers and waa laa, it pops up. LOLOLOL!!!

Mama, Try google maps, google earth, or something like it to get your lat/lon for your house. I don't remember what exactly I used. I think I just used my address, but I don't remember for sure.
