- Nice today into Thursday.
- Shower and thunderstorm chances Thursday night and Friday.
- Scattered showers and thunderstorms will be possible this weekend into early next week.
Weather advice:
As we prepare for spring, let’s make sure you have three to five ways of receiving your severe weather information.
.
Forecast Discussion
A nice day ahead of us.
Today’s wind gust map (mph)
We will have another day of gusty wind. It has definitely been a windy year!
Boaters use care, as always.
There is a higher than usual fire risk today over mainly southeast Missouri.
We will continue to have dry conditions today, tomorrow, and most of Thursday.
Temperatures will slowly trend higher as we move through the week. Can’t rule out an 80 degree reading this weekend! About time.
The latest six to ten and eight to fourteen day temperature outlooks (see below) have been trending warmer. Perhaps we will finally have some mild spring temperatures. I know many of you have been asking.
A couple of weak frontal boundaries will move into the region Thursday night through Monday.
The highest rain chances will be late Thursday night into Friday night.
A few rumbles of thunder will be possible, as well. But, at this time, the threat of severe weather appears nil. I will monitor that, as well. It is May and our peak tornado season is May into early June.
What is the probability of 0.25″ of rain or more falling within a 24 hour period. This is centered around Friday.
What is the probability of 0.50″ of rain or more falling within a 24 hour period. This is centered around Friday.
What is the probability of 1.00″ of rain or more falling within a 24 hour period. This is centered around Friday.
There remain questions about the Saturday through Tuesday time-frame. For now, I have low-end shower and thunderstorm chances. Some of the guidance indicates very little in the way of activity. Thus, it is possible that we remain mostly dry Saturday through Tuesday.
With that said, it will be warm and somewhat more humid. I kept some scattered thunderstorms in the forecast. I will monitor and update as confidence increases in the final forecast.
I would not cancel any weekend plans. I would monitor updated forecasts.
One thing is for sure, it is going to finally warm up! Perhaps 80s by early next week.
Rainfall totals through Tuesday morning.
Rain totals will vary depending on thunderstorm activity. Thunderstorms can always produce higher rain totals.
For now, I have low end rain chances Saturday into Monday. The bulk of this rain, however, will fall Thursday night into Friday evening.

This outlook covers southeast Missouri, southern Illinois, western Kentucky, and far northwest Tennessee.
Today through April 18th: A couple of the Saturday afternoon and night thunderstorms could produce damaging wind and hail. The tornado risk is low, but not zero. Mainly over Missouri for the tornado risk. The line will weaken with time as it moves farther east.
.
Today’s Storm Prediction Center’s Severe Weather Outlook
Light green is where thunderstorms may occur but should be below severe levels.
Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.
One is the lowest risk. Five is the highest risk.
A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.
