-- Changed Discussion --
(Today through Tuesday) Issued at 403 AM EDT MON MAR 19 2018 The latest surface map features low pressure moving across the southern Plains. A weaker inverted trough is currently aligned from the Tennessee Valley to the central Appalachians, with a more defined warm front aligned from west to east across the Gulf Coast States. Aloft, an upper level low is moving east across the southern Plains. Some showers have broken out across the Tennessee Valley overnight, thanks to some ongoing isentropic lift between 850 and 700 mb. Drier air in the low levels have kept this activity out of eastern Kentucky. The dry air will continue to keep most of our area precipitation- free through the morning, with the exception of perhaps a few sprinkles. Moisture will be on the increase this afternoon, as the short wave and surface low continue to trek east across the Mississippi Valley. Showers, and perhaps a few storms will threaten from southwest to northeast, with the best rain chances holding off until this evening as the surface low moves across the eastern portion of the Commonwealth. Temperatures will top out in the upper 50s to lower 60s. Some dry slotting will work in after midnight and through the morning on Tuesday, with less rain chances. Light precipitation will then fill back in again across the area during the afternoon, as a deeper trough takes shape across the eastern CONUS. The surface low will be just off to the east, allowing for a good gradient of temperatures. Highs on Tuesday will range from the mid 40s across our northwest to the mid 50s bordering Virginia. .LONG TERM...(Tuesday night through Sunday) Issued at 403 AM EDT MON MAR 19 2018 The long term forecast discussion will follow shortly.
