Happy hump day and Wednesday to everyone. A little bit cooler out there today with highs in the upper 80's, near 90. Pleasant news in the forecast though, as cooler and drier temperatures will funnel in Thursday. Taking a look at the surface map below, you can see a high pressure system in the northeast. Due to the clockwise flow of high pressure systems, cooler and drier air from Canada will move in, allowing for a taste of Fall Thursday and Friday (annotated by the blue arrows).
Today will be another day of dry conditions across the valley. We could see an isolated shower or two develop in the higher elevations, but overall very limited rainfall expected. As we get into Thursday, that cooler and drier air will move in allowing for a mostly sunny afternoon.
Taking a look at the CPC (Climate Prediction Center's) 3 to 4 week outlook for precipitation, well below average precipitation expected. This isn't very good news, as we are in need of rain across east Tennessee. Looking at the latest data our best chance of rain in the next 7 days will come Tuesday (next week) as another front will move through allowing for limited chances of rain ahead of it. We will keep a close eye on that as we get into your weekend.
