... A wedge of moist high pressure will persist across the area into Tuesday. A cold front will then move across the mountains Wednesday and become stationary thru Thursday. This front will maintain a chance of showers and thunderstorms each afternoon until dry high pressure builds in Friday and lingers through the weekend.
NEAR TERM /THROUGH TONIGHT/... As of 615 AM EDT...A back-door cold front continued to push southward into northeast GA. Behind the front, an easterly low level flow had forced some shower activity near the Blue Ridge Escarpment in NC. A few other showers were developing in the weak upglide above the shallow sfc-based air mass moving down from the northeast. The chances for additional showers will improve thru the morning hours near the escarpment down into northeast Georgia. Temps should be seasonally mild owing to the developing low cloud cover.
Weak cold air damming will be the rule of the day east of the mtns as a parent sfc high moves across Quebec to nrn New England. The models favor keeping most of the precip development over the mtns and near the Blue Ridge Escarpment where easterly upslope forcing will be best. Won't rule out a few other showers elsewhere, especially if we manage a few breaks in the overcast over the Piedmont in the mid/late afternoon. Thunderstorms are unlikely owing to the lack of instability and will be limited only to the srn fringe of the fcst area. Temps are a bit tricky, but either way should be below normal for the first time in a few weeks it seems. Even if we break out, the cloud cover will fill back in with sunset, with more light precip production expected in the E/SE upslope areas of the mtns this evening and early Tuesday morning. The cloud cover will keep a low diurnal range with min temps about ten degrees above normal.
SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... As of 155 AM EDT Monday: The ulvl pattern doesn/t change much over the short-term period as h5 heights remain fairly constant btw an Atl ridge and and mid-CONUS trof. Overall the pattern does become more cyclonically influenced and moderately energized Tue which will help push a nrn stream cP high east and allow a weak sfc wedge to lift north out of the CWFA. With the added pockets of ulvl energy combining with muCAPE values arnd 1000 J/kg...rather deep convection will support more tstms then has been present lately. Soundings show an increase in bulk shear as well...up to arnd 35 kts by Wed afternoon. Not expecting an organized storm mode...but a few cells or mutil-cells could become quite strong. The best available moisture will remain across the higher terrain as the mean sfc-h8 flow veers sw/ly to w/ly thru Wed night. Thus...PoPs are advertised highest across the mtns...esp Wed as a frontal zone pushes in from TN. Max temps will reach a cat or so abv normal each afternoon...while apparent temps will feel unseasonably warm (mid to upper 80s non/mtns) due to sfc td/s remaining arnd 70 F in sw/ly flow.
LONG TERM /THURSDAY THROUGH SUNDAY/... As of 225 AM EDT Monday: The strongest dynamics of the week will occur Thu thru Thu night as an upstream l/w trof axis finally crosses the area. Soundings show modest conditional instability which may be realized with the amt of deep layered forcing...altho the GFS keeps mlvl omega low-end. In any case...Thu shud see more widespread coverage of -shra/tstms...some of which could become stg/svr and linger into the overnight period. With deeper and layered cloud cover...max temps will be held right arnd normal Thu.
On Fri...the ulvl pattern becomes zonal and a weak sfc high will attempt to work in from the northwest. The models have varying ideas with how far southeast the high builds in over the weekend and therefore the placement of a moist sfc bndry. So...PoPs will remain quite low due to this uncertainty along with the climo-favored srn location of the front. Max temps will remain arnd or a bit abv normal Fri thru Sun...while td/s drop off 5-8 degrees by Sat and make for a nice Fall-feeling weekend.
