Current conditions.

.

Have there been any changes in the forecast over the last 24 hours?

No major changes.  I did add slight chances of afternoon rain showers Thursday afternoon over the western counties southeast Missouri and southwest Illinois.  Odds favor Thursday being dry.

.

Does the forecast require action?

Yes.  Avoid flooded roadways.  Many rivers are flooding.

We have a nice day on tap for the region.  I hope you have a chance to enjoy it!

Temperatures today will mostly be in the upper 50’s to lower 60’s.   The sunshine will make it feel warmer.

No rain today or tonight.

Our next storm system pushes into the region Thursday night and that will linger into Saturday.

A few scattered showers could occur as early as Thursday afternoon and night over the western half of southeast Missouri and southwest Illinois.  Odds favor most of the area remaining dry.

Rain chances will ramp up a little bit on Friday.   I would not cancel any plans.  I would monitor radars.

The best chance of rain, however, will be Friday night and Saturday.  This is when rain chances will be at or above 70%.  A few thunderstorms will also be possible.  Severe weather is currently not anticipated.  As always, monitor updates.

We will have to monitor the timing of the frontal passage on Saturday.  This will control when the rain comes to an end.  For now, I have rain chances continuing into late morning and the afternoon.  If we are lucky the front will push through faster and we will be finished with most of the rain before the afternoon hours.

Some locally heavy rain is possible from this event.  It does not appear that widespread flooding will be a concern.  There could be some ditches overflow and some rises in streams.

 

GFS rain totals

NAM model rain totals

.

PWAT values will be well above normal during this event.  That means a greater chance of moderate to heavy downpours.

Colder temperatures arrive Saturday night and Sunday night.  Lows will drop back down into the 30’s.  We will have to see if anyone dips below 32 degrees.

VIDEO UPDATES
.

These are bonus videos and maps for subscribers. I bring these to you from the BAMwx team. I pay them to help with videos.

The Ohio and Missouri Valley videos cover most of our area. They do not have a specific Tennessee Valley forecast but they may add one in the future.

The long-range video is a bit technical. Over time, you can learn a lot about meteorology from the long range video.

NOTE: These are usually not updated on Saturday or Sunday unless there is active weather.

I bring the following long-range outlooks from the BAMwx team.  They are excellent long-range forecasters.  These are more detailed than the images above.

Remember, long-range outlooks are always going to be a lower confidence level than short-term forecasts.

Long-range forecasting is not an exact science. There are many variables that determine the eventual outcome of a long-range forecast.
