Mostly Cloudy, Scattered PM Showers
It's another muggy start to the morning with temperatures in the low to mid 70s under cloudy skies. We may see a few breaks in the clouds this morning, but the large majority of the day will likely be cloudy. Model guidance differs considerably in the amount of forcing present today to generate showers and thunderstorms, but they almost all agree that we will get wet today. That's hard to argue against looking at Jackson's sounding from last night with precipitable water over 2". I think we'll see scattered showers and thunderstorms develop this afternoon, but I don't expect a washout by any means. Before the showers develop, I think highs will top out near 88. We'll be dry tonight, but cloudy skies should only allow temperatures to drop near 73 tomorrow morning. As a trough builds over the eastern half of the country at the end of the week, it should push a cold front through the area late Friday night. This will make for a very pleasant weekend with below normal highs and lows!
