Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 1032 PM EDT Mon Jun 14 2021
SYNOPSIS. Dry high pressure will bring slightly cooler temperatures to our region from tonight through Thursday. As this high pressure moves off the Carolina coast on Friday and Saturday, temperatures will rise again to above normal. Tropical moisture is forecast to move north out of the Gulf on Sunday and into the first half of next week.
NEAR TERM /THROUGH TUESDAY/. As of 1030 PM: Deep convection has moved south of the area; however, an isolated shower along and south of I-85, or even a thunderstorm, can't be ruled out through midnight or so. The thicker cirrus looks to be moving out of the area as well.
A weak cold front should clear the area overnight, with drier air filtering in its wake. Skies should become mostly clear and winds become light, but the gradual drop in dewpoints should limit fog potential. Still could see patchy fog and/or stratus in spots, especially the mountain valleys. Lows will be close to normal.
Dry, but still warm, high pressure will continue to nose into our area from the NW on Tuesday under a deepening upper trough. Guidance is in good agreement on profiles becoming too dry for even any mountaintop convection. So going with a dry forecast. Breezy winds expected across the mountains with slightly lower winds elsewhere. Highs will be about a category above normal.
SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/. As of 155 pm Monday: Anomalously low upper heights will predominate over the East through much of the period. Weakening surface high pressure overspreading the forecast area will support a continental air mass with unseasonably dry air/low surface dewpoints (afternoon values generally in the 40s over the mtns/50s elsewhere, 40s possible even in the Piedmont Thursday). Temps will also be a few degrees below climo through the period All in all. a pleasant couple of days for mid-June.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 205 pm Monday: With the upper trough expected to exit off the East Coast by early in the medium range, the relatively dry air mass will begin to modify late in the week, with temps likely returning to above-normal levels by Friday (although one more day with dry/ 50s dewpoints/convection-free conditions appears likely). After Friday, forecast confidence does down the tubes, as global models disagree on the intensity and track of a northern stream storm system passing over or near the northeast Conus and the evolution of an attendant frontal zone that will approach the Southeast next weekend. Only adding to the confusion is the state of the tropics, particularly with a disturbance that is expected to form over the Gulf of Mexico later this week. I suppose once could say that there's a consensus (albeit a weak one) that we could begin to see indirect impacts from said system or its remnants . with an increase in tropical moisture early next week. With this potential as well as the approaching frontal zone, PoPs will be ramped up to the chance range late Saturday . with chance PoPs persisting through the end of the forecast period. Above-normal temps are expected to continue into Saturday, while the potential for increasing/moisture clouds warrants a return to seasonal max temps and warm min temps during the latter half of the extended.
AVIATION /03Z TUESDAY THROUGH SATURDAY/. At KCLT and Elsewhere: Clouds diminish across the area with drier air moving in. Light W to SW wind, N at KAVL, expected overnight. With the drier air moving in, expect fog and stratus development will be limited to patchy locations in the mountain valleys. For now, going VFR at all sites through Tuesday. Winds will pick up from the N to NW during the morning Tuesday and continue through the day. Gusty winds expected at KAVL.
Outlook: Dry high pressure will dominate our weather through the end of the week. The potential for early morning fog and/or low cigs should be mainly confined to the mountain valleys through the week.
