Good evening Tennessee Valley and a very happy Saturday! Only a couple thunderstorms today which you probably missed because those were very early this morning. Since then the theme has been a good soaking giving most of us 1”+ of rain. Rain will continue to taper through the overnight and temperatures will plummet with the passage of the cold front. With that in mind, I am going to keep a small chance of a little snow in the forecast early Sunday morning. This snow shouldn’t accumulate because the surface will still be way to warm since high temperatures were in the 60s across the entire Tennessee Valley.
We’ll remain breezy through the overnight with sustained winds of 20-25mph and wind gusts nearing 35-40mph, so the wind advisory will continue through 7AM Sunday. Through the rest of the day upper level ridging and associated high pressure will develop west on Sunday so the clouds will gradually vanish.
This is great news because viewing of the total lunar eclipse will be perfect tomorrow though it will be incredibly cold so if you do venture outside be sure to bundle up. Under mostly clear skies lows will very easily dip down into the upper 20s Sunday night and early Monday morning. High pressure will pretty much control our weather on MLK day, but it’ll be cold under mostly sunny skies with high temperatures only making it into upper 30s and lower 40s.
Our next system will begin to develop on Tuesday in the form of an upper level trough with an associated area of low pressure and the subsequent cold front. This will bring the opportunity for rain Tuesday night, and then much of the day Wednesday looks wet with the cold front not passing until Wednesday evening or even Thursday morning. Again there is a small chance the residual moisture could turn to just a little snow Thursday morning.
From there Thursday and Friday look quiet before our next system potentially makes itself known on Saturday evening.
