Warm and dry weather can be expected until the approach of low pressure on Thursday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Very little changes needed for the forecast today. Have continued the idea of leaving pops near the Mason-Dixon line, as surface boundary will remained stalled over Northern West Virginia, and a weak shortwave will ride along the front this afternoon. Have kept higher cloud cover over the south as well. Temperatures again will be above normal. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... Zonal flow/flat ridging should maintain dry, but continued warm weather through Wednesday. Thereafter, POPs will be on the increase with the approach of low pressure, timing of which remains questionable on Thursday. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... A series of shortwaves and development of a broad, but shallow trough over the Eastern CONUS is forecast to support periodic rain chances and seasonal temperatures through the weekend. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... After early morning MVFR/local IFR fog mixes out, VFR conditions are expected through this evening as high pressure builds in from north of I 70. A stationary front south of I 70 could result in a few thunderstorms, but with limited coverage expected only mentioned VCTS at MGW. Patchy MVFR fog is again possible tonight. .OUTLOOK /WEDNESDAY THROUGH SATURDAY/... Low pressure should return periodic restrictions late Thursday though Saturday. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
