Area forecast discussion, Sep 2, 3:26 PM EDT, 1 hour 42 minutes before
Area Forecast Discussion National Weather Service Charleston WV Issued by National Weather Service Pittsburgh PA 326 PM EDT Sun Sep 2 2018 .SYNOPSIS... Very warm and humid as upper ridge remains in charge through early this week. A cold front approaches late in the week. && .NEAR TERM /THROUGH MONDAY/... As of 150 PM Sunday... Latest radar mosaic shows some showers and thunderstorms had developed over the ridges of the West Virginia mountains. In addition, storms over eastern Kentucky were moving east into our western counties. Outside of the precipitation, skies were generally mostly sunny. The showers and storms should continue this afternoon with overall coverage and intensity less than what occurred on Saturday. Storms will dissipate shortly early this evening with skies becoming mostly clear. As a result, expect dense fog will develop in the valleys as well as any location that sees rain today. With high pressure in charge, the areal coverage of diurnal storms that develop should be less than today with the scattered storms possible across the northern and central mountain counties. It will be hot again on Monday with temperatures in the lower 90s across moist of the lowlands with 80s in the mountains and even some 70s in the highest elevations. Combination of these temperatures and abundant low-level moisture will result in heat indices in the mid to upper 90s across the lowlands. Would not be too surprised to see some scattered locations reaching or even exceeding 100 degrees. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 315 PM Sunday... Big bubble of high pressure will be overhead through at least the middle of this week. Early September heat wave will be the result, with high temps soaring into the low 90s and possibly topping out at 95 at the warmest locations Tuesday and Wednesday. Will continue to highlight the heat in the HWO for now, but advisories may be needed at a later time. Thunderstorms will be possible in the mountains around the period of max heating on Tuesday. Although precip chances drop on Wednesday, can't rule out isolated shower or storms once again in the afternoon hours. Of course, with high pressure aloft, updrafts will have a very tough time punching through the dry air, so expecting limited coverage only in late afternoon and clear/very warm overnight. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 320 PM Sunday... Strong ridging will finally slide southward toward the end of the week. This will open the door for a quasi stationary boundary to slowly drift southward on Thursday into Friday and finally settle over our area. This front will be the focus for more widespread showers and thunderstorms right into next weekend, but at least there will be some relief from the heat. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... As of 150 PM Sunday... A few storms with IFR conditions will be possible across the mountains and coalfields through 23Z. After sunset, expect VFR conditions with only some mid or high level clouds. Dense valley fog with IFR conditions will once again form after 06Z. Other locations that see rain this afternoon could also see MVFR conditions in fog. Any fog that does form overnight should quickly dissipate after 12Z with VFR conditions across the entire area. A few mountain storms may develop late in the period. FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: May need brief TEMPOs for -TSRA. Fog coverage in question for tonight.
