Flipping The Warm & Humid Switch
As high pressure sits across Maryland and Pennsylvania this morning, return flow will again raise temperatures today. Highs will generally be in the mid to upper 80s with humidity unfortunately increasing as well. Looking below (valid for Saturday), we'll be at risk for quick sunburns. UV indices will be between 9 and 10 (high) for East Tennessee. Be sure to throw on the sunscreen, bring lots of water, and find a cool spot if you plan to be outdoors for extended periods of time.
Moving forward, better news is in the forecast for us (at lease in the shorter-term). As you can see below, HEAVY rainfall is expected across the Upper Mississippi Valley the next few days. In fact, areas of Illinois can expect upwards of 7+ inches by early next week. A low and front will sit nearly stationary just to our west, dumping lots of rainfall across that area of the US. Here at home, scattered showers/storms will be the main impact over the next 5 days with up to half an inch possible (averaged area-wide).
Most of us should stay dry into Friday, but as humidity increases, it will lead to afternoon pop-up showers/storms by the weekend. These will become more scattered for Sunday and and and early next week.
After a few days of pleasant weather, Mother Nature is cranking back up the heat and humidity. Remember your heat safety and take the proper precautions. Tomorrow and much of Saturday should be good days to cool off at the lake or pool.
