A Rainy Wednesday

Good morning bloggers,

The day begins with rain spreading across Kansas City.  It is a wet start to the day, and this upper level storm is tracking nicely to bring some beneficial rain. And, these are not cumulonimbus clouds, although there may be a few heavier downpours. This is just one large area of rain and the cloud type is nimbostratus.  You can tell by looking at the lightning map as of 7:30 AM:

And, here is the 7:30 AM radar map:

Screen Shot 2018-04-25 at 7.08.53 AMThis is a nice area of rain, that was increasing at 7:30 AM, and moving east-southeast across eastern Kansas.  As shown yesterday, this is directly related to a storm that produced snow in mid-January.  After this system moves by, we will begin analyzing the severe weather potential for early next week.  For now, however, let’s look at this storm, and the other system crossing the USA/Canada border.

This next map shows the upper level flow valid at 1 PM today. You can see the upper low that has formed over Kansas, which is producing this rain:

The colder air that comes down later this week from Canada is going to track all the way down to near the Gulf coast again. When the flow returns to the south over the weekend, it may be a struggle to get the moisture back into the plains states. Eventually, by Sunday or Monday, the dew points should reach into the 60s over Kansas, but as you can see below, on this 7 PM Sunday forecast map the dew points are highest near the Gulf coast, but a surge northward will finally occur.

This moisture is necessary to produce one of the main ingredients for the severe weather risks early next week.

Kansas City Weather Timeline:

  • Today: Cloudy with a 100% chance of rain most of the day.  0.25″ to 1.00″ of rain will be likely.  Temperatures may drop into the upper 40s during the heaviest rainfall.
  • Tonight:  Rain ending early with a clearing sky late. Low:  42°
  • Thursday:  Mostly sunny with increasing clouds late. High:  68°
