000 FXUS61 KRLX 231355 AFDRLX Area Forecast Discussion National Weather Service Charleston WV Issued by National Weather Service Pittsburgh PA 955 AM EDT Thu Mar 23 2017 .SYNOPSIS... High pressure under firm control with temperatures 10 to 15 degrees above yesterday. A warm front crosses tonight. Low pressure crosses Sunday and Tuesday bringing showers and storms. Above normal temperatures are predicted Friday into next week. && .NEAR TERM /THROUGH TONIGHT/... As of 950 AM Thursday... No significant changes were necessary to the previous forecast. High pressure remains in control during the period with dry, and warmer weather, as the high slides off to the east and upper heights build across the region. Still quite dry air in place, with somewhat poor relative humidity recoveries across spots overnight. Looking at another low RH day today, with RH`s bottoming out in the teens to 20s. The good news is, overall surface winds should remain somewhat light. A warm front will lift north across the region later tonight, with increasing clouds, and a slight chance for showers across the far north. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... As of 420 AM Thursday... Surface ridging along the southeast U.S. coast keeps the area in south to southwest flow of increasingly warm and humid air Friday into Saturday night, providing a nice start to the first weekend of spring. A southern stream upper level low opens up as it passes north of the area Saturday night through Sunday night, pushing a weakening pacific cold front through the area late Sunday. This is likely to make Sunday a wet day with a good chance for thunderstorms, given some instability in a theta e ridge and over 30 kts mean mid level flow. Precipitation begin moving out of the area from west to east Sunday night, as the system pulls out, leaving low level moisture in its wake. Temperatures close to central guidance, including a warm Saturday. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 420 AM Thursday... Mild, moist but progressive spring pattern prevails this period with southern stream systems pulling cold fronts through the area every three days or so. One front crosses late Tuesday. Models begin to diverge on when the next upper level low ejects out of the southwestern states later next week. Temperatures close to central guidance, which is below the MEX early on. && .AVIATION /14Z THURSDAY THROUGH MONDAY/... As of 945 AM Thursday... VFR conditions for the period with light southerly surface winds. Mid and high clouds increase after 21Z. AFTER 12Z FRIDAY... IFR possible in rain Saturday night and Sunday. && .RLX WATCHES/WARNINGS/ADVISORIES... WV...None. OH...None. KY...Freeze Warning until 10 AM EDT this morning for KYZ101>103-105.
