Area forecast discussion, Jul 5, 2:53 PM EDT, 1 hour 56 minutes before
AREA FORECAST DISCUSSION National Weather Service Charleston WV 253 PM EDT Sun Jul 5 2020 .SYNOPSIS... Heat continues. Daily afternoon/evening thunderstorm chances for the work week. && .NEAR TERM /THROUGH MONDAY/... As of 1245 PM Sunday... The region will remain in a hot airmass, with moisture slowly increasing. This will provide another hot afternoon on Monday, with a better chance of afternoon showers and thunderstorms. Chances increase throughout the area, with the mountains being most likely. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 230 PM Sunday... Ridging begins to weaken during the short term period and a surface low forms to the south. The low is expected to strengthen as it moves toward the East Coast and will pull moisture from the Atlantic into the area. With this increasing moisture as well as diurnally driven instability, showers and thunderstorms are possible each afternoon and evening. Temperatures in the short term period are expected to remain 5-10 degrees above normal. Highs in the lowlands are forecast to reach upper 80s to mid 90s with lows in the upper 60s to low 70s. In the mountains, highs will likely be in the 70-80 degree range with lows in the 60s. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 245 PM Sunday... An upper level trough develops to the west and then strengthens as it progresses towards the area. Models indicate this trough will begin to absorb the surface low and push it up along the East Coast. There are some discrepancies in model timing for the exit of the low. The GFS has much faster timing and pushes the system into New England early in the weekend...the ECMWF however, keeps the low further south until late in the weekend. A trough pattern remains for this area through the end of the long term period. Temperatures remain hot throughout the period though they may drop somewhat closer to normal over the weekend. Chances for showers and thunderstorms to develop are possible each afternoon and evening. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... As of 1250 PM Sunday... VFR conditions will persist through the period, with the exception of a small chance of brief IFR in a shower/thunderstorm this afternoon, and some river valley fog late tonight and early Monday. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: Timing, density, and location of river valley fog late tonight could vary.
