AREA FORECAST DISCUSSION National Weather Service Charleston WV 314 AM EDT Fri Apr 16 2021
SYNOPSIS. Upper level low pulls away today. Minor weather disturbances this weekend bring patchy light rain. Warmer early next week. Strong cold front midweek.
NEAR TERM /THROUGH TONIGHT/. As of 215 AM Friday .
Lowered temperatures this morning across western counties where clouds have dissipated and surface wind has decreased. Patchy frost was maintained in northeast KY, but given trends, the coverage may be a bit underdone.
Upper level low will continue its slow track eastward today to a position just off the northeast coast this afternoon. As it does so, the influence it has on the area will gradually lessen. This, however, will not be fully realized until later today as upper heights begin to rise. In the meantime, the extent of stratus and stratocu remain the forecast challenge. While many areas will sunshine this morning, this is expected to fill back in as lingering low level moisture remains trapped beneath an inversion . especially north of the I64 corridor. Gusty winds will develop during prime mixing hours which will maintain a chill to the air despite high temperatures a few degrees higher than yesterday.
S/W ridging gradually advances into the region tonight along with some mid and high clouds. Current thinking is enough cloud cover will exist to mitigate any patchy frost. Having said that, this is a bit of a low confidence forecast at this time. Concern will be passed on to the day shift for at least a mention of patchy frost in hollers and sheltered valleys.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. As of 252 AM Friday .
Weak sfc high pressure is prog to shift east of the region early Saturday and generally weaken further/dissipate. A dampening H5 low transitioning to elongated vorticity lobes should then approach/advect in from the west along with a weak surface trough possibly shifting east across the CWA. In wake of this sfc trough, modest low level moisture advection from the Great Lakes may occur along with an increase in weak, but widespread, mid level lift. Thus, patchy to areas of light rain should occur at times . and I emphasis very light. This patchy precip should generally dissipate Saturday night, but renewed light precip development (with possibly somewhat greater coverage) may occur Sunday as a stronger H5 s/w trough advects towards the region . with the trough axis moving across Sunday night. High temps over the weekend will continue to be below normal for Mid April, and currently forecast values may be a little too optimistic (especially if we end up with thicker cloud cover and greater precip coverage).
LONG TERM /MONDAY THROUGH THURSDAY/. As of 301 AM Friday .
H5 s/w ridging should influence area weather on Monday with a drier atmospheric column promoting thermal modification. A rather strong longwave trough is prog to dig south into the Plains Tuesday through midweek and push another strong cold front towards our area. Sfc cyclogenesis along the front on Tuesday will aid in developing/strengthening warm southerly flow for our area . with temps Tuesday likely being the warmest of next week. FROPA should occur either Tuesday night or Wednesday, with timing discrepancies still existing with the latest guidance output. Timing of FROPA will greatly influence daytime highs on Wed. If the deterministic GFS and CMC verify, then temps during the day Wed will be downright chilly for this time of year. A band of showers will likely accompany the cold front, but limited moisture advection ahead of the system should preclude significant rain amounts.
Strong 1025+ mb sfc high pressure will then build into the region for the second half of next week . promoting dry and cool conditions.
AVIATION /07Z FRIDAY THROUGH TUESDAY/. As of 215 AM Friday .
VFR stratus will continue to erode into the early morning hours, allowing HTS/BKW/PKB/CRW to experience some clearing. Stratocu may fill back in late morning into the afternoon, though bases will remain VFR. Stratus is expected to hold at CKB/EKN and lower into MVFR in the 10-17Z time frame before scattering and lifting late.
West to northwest surface wind become gusty 20 to 25 kts late morning into early afternoon. Flow slackens tonight becoming variable in direction.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY . FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: Timing of MVFR conditions at CKB/EKN could vary early this morning.
