Area forecast discussion, Jun 28, 2:36 AM CDT, 4 hours 12 minutes before
Area Forecast Discussion National Weather Service Morristown TN 336 AM EDT Thu Jun 28 2018 .SHORT TERM...(Today through Friday)... Convection lined up from western KY to east TN this morning will bring a wet start to the day. But high pressure will begin to build in behind the departing H5 trough, and we expect to see convective activity diminish from north to south this afternoon and evening. For Friday, convection will be diurnally-driven and mainly confined to higher elevations of the mountains and Plateau. Temperatures will be well above normal Fri-Sun. .LONG TERM (Friday Night through Wednesday)... The upper level ridge axis will be just to the west to start the long-term period. The ridge axis will move over the area Friday night into Saturday morning. With this, there will be some weak moisture return by Saturday afternoon. The best moisture on Saturday will be across the southern half of the forecast area and have around 20-30% chances for afternoon showers and storms with dry conditions further to the north. Saturday will be the hottest day of the long-term forecast with highs in the upper 80s to low 90s for most locations. The ridge begins to break down late Saturday night into Sunday as an upper level trough moves into the Upper Mississippi River Valley and eventually the Great Lakes region by Sunday. At the surface, there will be a front associated with the upper level trough. Moisture will continue to increase across the area with southwesterly flow throughout much of the atmosphere. Afternoon showers and storms will be more widespread on Sunday and Monday. The front to the north will slow and stall early next week as the trough races off to the northeast and the ridge tries to become established. For now, it looks as though the front will stall to the north across Ohio River Valley keeping highs in the upper 80s to low 90s for most locations. Also, expect numerous to widespread diurnally driven showers and storms each afternoon next week. Overall, expect this to continue into Wednesday on the 4th of July. && .PRELIMINARY POINT TEMPS/POPS...
