Soggy Thursday…..Fabulous Friday

by Steve Dunford

Over the next few hours, we will receive moderate to heavy rainfall, with a few rumbles of thunder, across Southern Illinois.  The large area of showers extends into Northeast Missouri.

It is on my bucket list to download a radar program, with velocity on storms.  My estimate is the storms are moving at a good clip at 30-40 mph.

We are still under a marginal risk for severe weather.  This will mainly be determined if the sun will come out after this round of percipitation, to provide instability in the atmosphere.  It is possible this large area of precipitation that is coming through will take a lot of the convective energy with it.

I do not have any scientific evidence to prove this, but it is out of observation.  Storms have been moving northwest to southeast now for about a month.  There is a possibility that we might have an early fall.

With winds shifting to the NNE after the cold front passes in the next 24 hours, they will blow the humidity out of here for the weekend.  With highs in the low 80’s, the air will have a fall feel to it.

Temperatures will moderate into the mid to upper 80’s by mid week.  There is not a 90 degree day in sight.  Enjoy it, and give your air conditioner a break, as window opening weather is on the way.

Below, is the Hazardous Weather Outlook and the Seven Day Forecast.
