We offer regional radars and local city radars – if a radar does not update then try another one. Occasional browsers need their cache cleared. You may also try restarting your browser. This will usually fix any problems.

During the winter you can track snow and ice by clicking the winterize button on the local city view interactive radars.

The National Weather Service definition of a severe thunderstorm is one that produces quarter size hail or larger, 58 mph winds or greater, and/or a tornado.

Sunday night and Monday: Thunderstorms will be possible. Lightning would be the main concern. A few storms could produce high winds. There is a small risk of severe weather over mainly southeast Missouri. Monitor updates.

Our rain maker is developing and will move into our region tonight (Sunday night/Monday morning).

You can see it here on the GOES 16 satellite image. Moisture is being pulled in from the Pacific Ocean and the Gulf of Mexico. Typical for this time of the year.
.

.

I made some small adjustments in the going forecast.

I adjusted high temperatures on Tuesday. Lowering them a bit. I also mentioned snow flurries are a possibility at the end of this system. It does not appear to be anything to worry about. That would mainly be Monday night and Tuesday. Again, not concerned about accumulation (if they occur at all).

I also slightly increased wind speeds on Monday.

The main rain band will enter southeast Missouri between 12 am and 3 am. There will be showers ahead of the main line. The main rain shield should be a solid band of precipitation.

Gusty winds are likely on Monday into Monday night. Wind gusts above 35 mph will likely occur (esp on Monday during the day).

Temperatures will be well above normal today through Monday morning. Warm air pulling northward ahead of our cold front.

Temperature may remain in the 50’s for overnight lows (tonight/Monday morning). Upper 40’s to middle 50’s.

You can see how much above normal temperatures will be on this map. Temperature anomaly map.

Here is the NAM model guidance future-cast radar for 12 AM Monday.

This next image is 3 AM Monday

This next image is 6 AM Monday

This next image is 9 AM Monday

.
You can see the bulk of the rain comes through all at once.

We could have some wrap around showers or flurries Monday afternoon into Tuesday morning. Nothing of significance.

We should remain dry Tuesday night into Friday afternoon.

Another rain maker is possible Friday night into the weekend. That event should be similar our current one.

Here are my rainfall total forecasts. What is the % chance of X amount of rain falling.

Southeast Missouri

Totals across southeast Missouri may end up a bit heavier than the rest of the area.

Southern Illinois, western Kentucky, and northwest Tennessee

With the recent heavy snow pack we could have some water issues in a few locations. Let’s keep an eye on it. This does not appear to be a large flash flood event. Just some pockets of problems could occur.

The snow will likely have melted by the time the line of showers and thunderstorms arrive.
