Good morning bloggers,
We are now going to put this dry spring to rest as summer begins with the Summer Solstice at 6:09 PM this evening. Just as summer begins rain is likely with a line of thunderstorms forming near an advancing cold front.
Thunderstorms will be developing along and near a cold front that has some punch to it this morning. It will weaken tonight. Here is a look at the front as of 6 AM:
There is one rather big difference with this set-up from the past few rain chances. The dew points are much higher with a strong flow of air from the Gulf of Mexico. The past two chances of rain had dew points in the 50s to near 60 and the rain just fell apart as it didn’t have the rich moisture to work with. There is no excuse for this to happen tonight and if the timing of the front works out later this evening we will have a very good chance of heavy thunderstorms between 9 PM and midnight in Kansas City, earlier to the north and west. The green numbers show the dew point temperatures with the red numbers being the actual surface temperatures. 70°+ dew points are in place in the region and this will help provide the fuel for torrential rainfall and if you get under one of the heavier thunderstorms tonight over an inch of rain will fall. Last night I forecasted 0.25″ to 1.25″ of rain tonight and it is still looking good. Here is the Powercast I showed valid this evening:
This next Powercast would be valid at 3 AM, but the latest data is a bit faster than this:
Thank you for stopping by and spending a few minutes reading the 41 Action Weather Blog. I will update this blog later this afternoon as the thunderstorms begin forming. Watch 41 Action News for details as we analyze and update this developing chance of rain.
