A Powerful Storm Develops Over The Plains

Good morning bloggers,

I have been pretty busy with the KC Pet Telethon and a few other projects. The Telethon raised $125,000 for the Humane Society of Greater KC, and in my 19 years hosting the telethon with Windy, Stormy, Breezy, and now Sunny, we have raised over $2 million.  I am so proud that I have been involved in this fundraising effort.  The weather was great for the dogs and cats arriving at the event Sunday evening, and now a storm is approaching, and this is no ordinary storm.

This storm is being caused by a very strong and negatively tilted storm coming out of the southwestern part of the nation and ejecting out into the plains:

This map above shows the 500 mb flow (18,000 feet above the surface).  The negatively tilted trough and upper low will be ejecting out into the plains and it will help form a band of rain and thunderstorms over the western plains later tonight into early Wednesday morning. This will then blow through eastern Kansas rather fast, and the fast movement and timing of the rain may limit amounts.  Some of the models have these rain holes, or rain shadows where this powerful storm may leave a few spots with around 1/4″ of rain or less:

The higher precipitation amounts our northwest Nebraska into Wyoming and the Dakotas will be in the form of snow, and 2 1/2 feet of snow are possible with blizzard and life threatening conditions:

For Kansas City, our pressure will get very low tomorrow as this system goes by.  And we will see a few rounds of rain, and possibly a few thunderstorms. Then, we will get “dry slotted” and the rain will shut off Wednesday, around noon tomorrow.

Kansas City Weather Timeline:

  • Today:  Rain showers likely this morning with around 0.10″ to 0.20″ possible.  A few showers likely this afternoon. Cloudy with a high of 55°.  The Dew Point will surge into the lower 50s with south winds 10-20 mph.
  • Tonight:  A 100% chance of rain, possibly heavy at times. A few thunderstorms are possible. Rainfall amounts between 0.25″ and 1.o0″ possible. Temperatures staying in the 50s.
  • Wednesday:  Morning showers and thunderstorms likely with an additional 0.10″ to 0.75″ possible, for a storm total of 0.45″ to 1.95″ likely.  High:  64°

It has not been over 64° since October 30th. It may come close on Wednesday. If the sun does not break out in the warm sector on Wednesday, then it may stay just below 65° again. This has been the longest stretch ever in KC history that it has been below 65°. KC had never gone all of November, December, January, and February without one 65° day until this LRC.

Thank you for spending a few minutes of your day reading the Action Weather Blog featuring Weather2020 and the LRC.  Have a great day!

Gary
