Area forecast discussion, Aug 14, 2:49 PM EDT, 0 minutes before
Area Forecast Discussion National Weather Service Morristown TN 249 PM EDT SUN AUG 14 2016 .SHORT TERM (This Afternoon through Monday)... Seeing a few scattered showers and storms showing up on radar this afternoon with the coverage limited to NE TN and SW VA. Moisture is a little bit higher across NE TN and SW VA with PW values ranging from 1.7-1.8 inches with values in the 1.3-1.5 inch range south of I- 40. Therefore, expect showers and storms will remain limited to NE TN and SW VA throughout the afternoon and evening. SBCAPE values are around 1500-2000 J/Kg in NE TN and SW VA and there could be a strong storm or two but do not expect anything severe. For tonight, any ongoing convection should quickly come to an end due to the loss of daytime heating. With the scattered showers and storms this afternoon, expect there could a be a few areas of patchy fog tomorrow morning across NE TN and SW VA. On Monday, a weak shortwave trough will move northward out of the Gulf of Mexico into the Southern Appalachians. This trough will ride around the periphery of the Atlantic ridge. PW values will increase into the 1.7-1.9 inch range with southerly flow in the mid and lower levels. Therefore, expect showers and storms will a bit more numerous across the forecast area. Models indicate that SBCAPE values will range from 750-1500 J/Kg with weak mid-level flow. Therefore, not expecting any strong to severe storms but there will be some heavier downpours. .LONG TERM (Monday Night through Saturday)... Ridge is still holding strong over the area while the frontal boundary to our north will still likely be stalled out and struggle to move further south. Warm temperatures will lead to diurnally driven showers and thunderstorms likely each afternoon/evening. Front looks to make a little southward progress before it fizzles out and leaves decent moisture set up over the area, which will lead to some of the better rain chances on Wednesday/Thursday. Another system/frontal boundary will make a run at the region at the end of the forecast which will lead to continued rain chances and slightly cooler temperatures through the end of the 7-day forecast. && .PRELIMINARY POINT TEMPS/POPS...
