HUNTSVILLE, Al - Good evening Tennessee Valley and a very happy Sunday! It seems we found ourselves dealing with a very stereotypical winter day across the Tennessee Valley that featured cloudy skies and temperatures that struggled to get much higher than the upper 40s. Unfortunately, this pattern will continue through the start of the new workweek. The good news? We’ll be dry tonight and temperatures will be above average in the upper 30s for lows thanks to the thick cloud deck.
Mostly cloudy to overcast skies will be the theme on Monday with maybe a quick peak of sunshine in the late afternoon, but I wouldn’t get your hopes up for that. This pattern will change thanks to an area of high pressure that will eventually push through the Tennessee Valley on Tuesday. This will bring welcomed sunshine, but temperatures will remain below average in the upper 40s.
As the high pressure continues to move east our winds will begin to change direction ushering in some warmer weather while still mostly sunny on Wednesday. High temperatures on Wednesday will be just at or above average in the low and mid-50s.
Now I noticed a very quick moving system that looks to move across the Tennessee Valley on Thursday. The models do differ a bit on the timing with the GFS holding the rain off until late morning and early afternoon while the EURO brings at least some light rain in Thursday morning. Still, once the rain arrives it looks to be widespread the rest of the day and even through the overnight hours.
Friday looks like it should be a warm mostly to partly sunny transition day. An upper level system will begin developing to our west which comes in the form of an upper level trough that will add a strong southerly component to our winds which in turn will allow temperatures to be near 60 degrees. The rain with this system would come on Saturday.
From here we see some major differences between the GFS and EURO. Eventually this system will have an associated cold front. The GFS brings the cold front through during the day Saturday calling for a transition to snow Saturday evening and Saturday night. The EURO is a solid 12 hours slower but does bring the opportunity for some light snowfall on Sunday morning. We are still a week away from this so accumulation will not even be considered.
The bigger story looks to be the vastly cooler air that would come to the Tennessee Valley next Sunday.
