As I said earlier in the week, a break in the heat is near. In fact, Friday and into this weekend we will be back in the mid 80's for high's. A low pressure system and its associated cold front are making their way southeast this evening bringing with it showers and thunderstorms. We are seeing a few isolated storms popping up already and this will continue into the afternoon.
The latest high resolution model suggests more widespread showers and storms moving in by late this afternoon and into the overnight hours. I am not expecting a washout for the area but localized flash flooding (in heavier thunderstorms) can't be ruled out for flood prone areas. Overall, tonights activity will be scattered at times with heavier downpours, gusty winds, and lightning all likely.
The Weather Prediction Center has a QPF (Quantitative Precipitation Forecast) of around 1 inch of rainfall through very early Saturday morning. Higher rainfall amounts are expected in portions of northeast Tennessee. Overall, we will add some much needed rain to the bucket and also cool off a little bit.
Looking ahead to the 3-4 day model guidance, we will return to partly cloudy skies and the chance of afternoon pop up storms each day for the start of the work week. Temperatures will also remain average for this time of the year, in the upper 80's for the first half of next week.
Looking ahead to end the month of August and into the first week of September, we will likely feel slightly below average temperatures. So yes, FINALLY some cooler temperatures for east Tennessee. Don't get too excited, though, as we will remain pretty muggy and likely continue the chance for afternoon pop up storms.
