We were spoiled last week with temperatures in the low to mid 80's and low humidity. Unfortunately, that summer time heat is back. For most of us today we will break the 90 degree mark. If you take a look below, a high pressure system (currently east of TN) has kept us high and dry the past several days. This high has shifted eastward allowing for increased temperatures and humidity to flow into our area. As depicted by the arrows, moisture and temperatures are being pulled in from the Gulf due to the clockwise flow of the high pressure system.
Luckily a weak cold front will pass through tomorrow afternoon providing a break from the 90's. Ahead of this front, scattered afternoon showers and storms are possible both Tuesday and Wednesday. The latest models suggest our best chance of rain for the area is Tuesday into Wednesday morning. Once this frontal boundary moves through, expect high's in the mid to upper 80's through much of the work week. Isolated to scattered showers still remain in the forecast each day this week as day time heating is the primary initiator.
Over the next 5 days (through Friday), models suggest rainfall totals between a quarter and half an inch. As I mentioned, each day will contain the possibility of your typical summer time afternoon pop up storms. Other than the chance of storms in the afternoon, we will stay mostly sunny with muggy conditions and average temperatures.
As many are planning to start the new school year this week, here is what your forecast looks like for today. Oak Ridge Schools starts today with Anderson County, Clinton and many others starting August 2nd (later this week).
Thats all we have today, but I hope everyone stays cool and dry this week.
