Saturday Update:

Snow is falling across portions of southeast Missouri and southern Illinois.  Slushy accumulation is being reported in some areas.

Here is a photograph from Candice Sauerbrunn.  This was between Cobden and Anna, Illinois.

This is a great radar to track the rain/snow.  Blue, pink, and purple is the snow.  Green, yellow, and red represent rain.

Heavy Rain Next Week:

There is the potential of heavy rain next week.  Several rounds of rain are likely.  Model guidance continues to indicate that several inches of rain may fall in the Ohio and Tennessee River basins.  Monitor updates.

This is an ensemble forecast map.

What are ensembles?
.

.

Want to learn more about ensembles?  I posted this link a few weeks ago.  Click Here.

This is a strong signal for heavy rain in our region.  I would not be surprised if someone tops 5 inches of rain over the coming seven day period of time.
.

.

Let me show you some more ensembles.  These are three different models.  It is amazing to see every model agree on the potential of heavy rain over the coming seven days.

The models are showing some extreme numbers.  Does that mean this will happen?  There is agreement among the data.

The details, however, will need to be ironed out.  There will be some bands of very heavy rain totals with the coming events.  Just because these graphics show X amount of rain falling in your county does not mean it will happen.

The point of the graphics:  There is agreement among the guidance that a heavy rain event will occur over the coming seven days.  Several chances of rain and thunderstorms.  The exact placement of the largest rain totals is still an unknown.

What does all that mean?  It means there is a risk of flooding over the coming week.  Monitor updates.

Here is what the WPC/NOAA is forecasting over the next seven days.

Let’s take a look at the GFS model guidance future-cast radar.  This is from Sunday night through next Sunday.

Timestamp upper left.

The big question is whether the front stalls in our region Tuesday and Wednesday.  If that occurs, then heavy rain totals would be the end result.

Green, yellow, and red represent rain.  Blue is snow.

Timestamp upper left.  0z is 6 PM.  06z is 12 AM.  12z is 6 AM.  18z is 12 PM.

We will need to monitor river stages.  Rivers are going to rise over the coming weeks.
