Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 1043 PM EDT Mon Sep 27 2021
SYNOPSIS. Dry high pressure will dominate the region through Tuesday, with warming temperatures. A back door cold front will approach from the Mid-Atlantic region on Wednesday and move south of the area by late in the week. Another cold front may approach from the northwest by early next week, with better moisture possible.
NEAR TERM /THROUGH TUESDAY NIGHT/. As of 1015 PM EDT Monday: skies remain clear with most sites reporting light to calm winds late this evening. Conditions should remain quiet thru the overnight and into the morning with low temps expected to average just a few degrees below normal. Fog and low stratus will likely redevelop across the mtn valleys and some lakes and rivers outside the mountains during the pre-dawn hours before burning off by late morning.
Otherwise, the upper trof will remain centered near the East Coast thru the period, while sfc high pressure remains centered off the Carolina Coast. Continued SWLY low-level flow and the building of a strong upstream ridge into the area will keep things dry with warming temps. Highs tomorrow are expected to climb about 4 to 6 degrees above climatology, as winds continue to favor a SWLY direction across the lower terrain, and a NWLY direction over the mtns.
SHORT TERM /WEDNESDAY THROUGH THURSDAY/. As of 200 PM EDT Monday: No significant changes made to the short term. A potent trough will dive south out of Canada to the New England coast Wednesday into Thursday. An associated back door cold front will probably hang up near the area as better forcing pushes offshore and the front itself becomes parallel with the northwest flow aloft. As such, any significant cooling with the front will probably hold off until early in the extended period. Mostly sunny skies will prevail, except possibly in the vicinity of the front as it edges into the region from the north. A steep surface based inversion late early each morning may support fog or low clouds focused across the mountains. Highs will likely be above normal in the 80s with overnight lows a bit above normal as well.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 235 PM EDT Monday: Forecast uncertainty remains above normal during the extended period. Friday or Saturday are probably the most likely days for a wedge pattern to take hold with modest high pressure building into the Mid-Atlantic states. Although with below normal confidence in the possible wedge configuration, opted to only lower temperatures a touch below guidance, in line with neighboring offices. Skies will be mostly sunny through Saturday except perhaps near the wedge boundary and slowly increasing high clouds.
An assortment of weak 500 mb lows may interact across the Central States and gradually break down long wave ridging over the area thing weekend into early next week. The 12Z operational GFS seems entirely too aggressive in doing this (even compared to many of its ensemble members) and therefore is thrown out. Sunday, Increasing moisture out of the west and possibly associated with the wedge boundary as it lifts back north as a warm front will increase cloud cover with a slight chance of showers remaining in the forecast north of I-85. Shower chances and cloud cover may continue to increase into early next week with a broad trough to our west injecting additional moisture via southwest flow aloft. Near to slightly above normal temperatures seem like the best bet given the expected pattern.
AVIATION /03Z TUESDAY THROUGH SATURDAY/. At KCLT and elsewhere: expect VFR conditions to persist through the 00z taf period at all sites, with the exception of a return of fog/low stratus over the usual mtn valleys early Tues morning. Confidence is still not very high that KAVL will actually see IFR (or lower) conditions tomorrow morning, so their restrictions are limited to 3sm and sct003 between roughly 09-13Z. As has been the case the past couple of mornings, fog and low stratus will likely develop over lakes and rivers in the foothills early Tuesday, but it's unclear if any of this will drift over the terminals (KAND/KHKY primarily), so I maintain VFR conditions at the other sites through the period. Otherwise, winds will become light to calm later tonight/ overnight and pick back up from the SW again tomorrow.
Outlook: Mostly VFR conditions are expected to persist thru the week, however mtn valley fog is likely each morning.
