We will kick off the new work week with sunny skies and a few high clouds. Looking at the latest scan across the US, high coverage is present across the area, with increasing cloud cover expected overnight tonight. As far as temperatures, we remain cool and below average with highs to be in the mid to upper 50s.
Working forward, a potent low pressure system will develop along the lee side of the Rockies, bringing warm temperatures followed by a line of showers/storms and cooler air thereafter. Breaking this down a bit further, the SPC has issued a day 3 Marginal for East Tennessee. The line, fortunately, comes during the overnight Wednesday and into Thursday. This means a lot of the instability (energy) associated will be cut into, limiting severe potential. With that said, there is still plenty of time in the forecast for things to change. The biggest threat will be damaging wind gusts and straight line winds. You can find the day 3 outlook below.
Looking at guidance, a line of showers and embedded thunderstorms will work east late Wednesday and into Thursday, providing heavy rainfall and gusty winds. Given the weakening of this system, we pan out better but we will continue to eye the severity potential with this. By Friday, sunshine and cooler temperatures will be present with highs in the low to mid 60s. This comes after highs Wednesday and Thursday are in the 70s.
That will do it for today, we start off the work week pleasant before cloud cover arrives Tuesday and onward. The good news is temperatures will progressively warm through the next couple of days, with highs by Wednesday in the upper 70s (and some low 80s).
