(Today and Tonight)...What is left of a weak and dissipating frontal boundary will drift into the area today. This marginal boundary should help to trigger some showers and thunderstorms especially north...but coverage not expected to be great. Will carry chance PoPs north and slight chance elsewhere. Other than a slight chance of a shower or thunderstorm early in the northern/central E TN mountains this evening...tonight should be precip free and end up mostly clear. Just some minor tweaks to MAV temps...which look reasonable overall. .LONG TERM...(Tuesday through Sunday)...Will remain in a summer like weather pattern through Wednesday. This means warm temperatures with highs in the mid 80s to around the 90 degree mark across the valley and diurnally driven...mainly afternoon... convection. Best chance of thunderstorm activity will be over higher elevations. Around the Thursday/Friday time frame...a cold front will move into the region. Models have been in poor agreement with the timing of this feature and where the boundary will stall. Overall...this will provide an increased chance of convection Thursday and Friday with some lingering activity possible into the weekend. Also...slightly cool air is expected to move in behind the front.
