Winter Hanging On…April 4

Stunning weekend and a terrific Monday!  I hope you were able to spend some time out of doors. It was 64 for the high on Saturday and 68 Sunday and today it soared to 78.

But don’t get used to that we have some chillier air in the forecast.  Yes, more frosty mornings are ahead. A front passed through today, so colder air will be spilling in tonight.  Some spots could see some frost in the morning, but it’s even more likely and widespread later this week.  By tomorrow morning in Nashville, it will be 38 degrees.  The kiddos will need a jacket at the bus stop..  The balance of the day will be lovely tomorrow, high 62.

The next approaching system will bring showers and thunderstorms on Wednesday. Right now the Storm Predication Center has put up in a “marginal risk” category.  By the way S.P.C.  is the branch of the National Weather Service that makes forecast for severe storms and issues watches during severe weather.

LISA SEVERE RISK REGION

A “marginal risk”, represented by green shading is a 1, the lowest category on a 1 to 5 scale. It means that isolated thunderstorms are possible.  You can expect 40-60 mph, hail up to 1″ and a low tornado risk.  The chart below defines the other risk categories.

Right now the timing is for Wednesday late afternoon and into the evening. Our futurecast model estimates about 3pm for the rain and storms to move into the corner of the mid-state.

The line may become more defined and intensify as it moves into Middle Tennessee before sunset.

But again, it does look like this system does not have the upper level support to produce the kind of storms we dealt with last week.

We are definitely looking for better weather this Thursday for our Surviving the Storm program.  We  are headed to Gallatin at Vol State.  Dan Thomas included more on that in his blog earlier today click here.

Cooler air will follow this next system. So much so, we could see a few snow flurries along the Cumberland Plateau on Friday.  This weekend frost will likely form again by the time we get to Saturday and Sunday mornings. Morning lows will fall to near freezing.

I’ll have an update on Channel 4 News at 10pm.
