Good evening Tennessee Valley and a very happy Saturday! A fair amount of sunshine this afternoon, allowed temperatures to reach seasonable numbers with the official high at HSV coming in at 52 degrees. Thanks to an approaching system scattered showers will be the theme through about the next 24 hours. That all begins tonight. I am confident some will remain dry, but I would keep the umbrella with you as you head out early tomorrow morning, and then keep it with you through the afternoon. This thanks to a mild increase in southerly flow.
With the approaching area of low pressure, southerly flow really kicks into high gear on Monday. This will not only bring ample moisture into the Tennessee Valley, but will send temperatures soaring into the upper 60s near 70 degrees. An approaching cold front will help support the development of even more rain. Unlike Thursday, Monday does not look like a complete washout. There do look to be periods of dry time or at the very least very light rain. Just like Thursday the heaviest precipitation looks to come Monday night and very early Tuesday morning. The rest of Tuesday looks to be dry.
From there models are in such disagreement it’s almost laughable. The one thing they do agree on is that another upper level system will develop next Wednesday and Thursday. That’s where it stops. They don’t agree on the strength or eventual location. The EURO takes the stronger low to the north which would bring more rain Wednesday night and Thursday. From there it brings wrap-around moisture in on Friday morning which thanks to temperatures would come as snow. The GFS takes a much weaker low right over the Tennessee Valley which would then keep the precipitation to our south.
I’ll get my hopes up that GFS track will play out since we don’t need the rain, and it keeps us dry Wednesday – the end of the weekend.
