-- Changed Discussion --
(Tonight and Wednesday)... Sunny and warmer today as high pressure covers most of the eastern states. Winds are much lighter today and temperatures are in the mid to upper 60s with dew points in the mid 30s to lower 40s. Another cold night tonight similar to Monday with the higher valleys of northeast Tennessee...southwest North Carolina and southwest Virginia again in the mid to upper 30s with frost. Have issued another Special Weather Statement for frost. Wednesday looks like another similar day to today but more warming with highs reaching the upper 60s to lower 70s. .LONG TERM...(Wednesday night through Monday)... High pressure and clear skies will be present through the work week and into the weekend. Low and mid level flow will transition from the northwest to out of the south...with temperatures slowly warming each day to normal by Saturday. By Sunday...a deep upper level ridge will move across the eastern US with a frontal boundary moving through this trough. As the front moves through the eastern Appalachians...low and mid level flow will be parallel to the front...allowing for slower movement and a longer time period of convection over the area. Models have been slowing down the timing of arrival of the showers...with scattered showers and thunderstorms expected Sunday late afternoon into the early evening...with only showers expected as instability weakens with the sunset. Scattered showers are then expected through the day Monday.
