SYNOPSIS. A dry cold front will cross the region from the north today. Dry high pressure will then set up over our region through Friday before a Gulf Coast low pressure system passes mostly south of the area Friday night into Saturday. Canadian high pressure builds back into the area Sunday and will maintain dry conditions through early next week.
NEAR TERM /THROUGH TONIGHT/. As of 215 am EST: A weak cold front over northern Virginia early this morning will settle southward and cross the western Carolinas as a dry cold front this afternoon. This boundary will reinforce dry air already in place due to the deep-layer northwesterly flow and associated downsloping east of the mountains. Anticipate plenty of upper 60s to lower 70s maxes east of the mountains today, with lower 60s in some of the lower mountain valleys. Fire danger from the dry air and slightly breezy conditions will be the main concern, as detailed in the fire weather discussion section. Dry high pressure will then get reinforced from the Great Lakes tonight, with plenty of minimum temperatures in the 20s and 30s around the region in good radiating conditions.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. As of 215 AM Thursday . A small scale upper level ridge will remain in place to begin the period while an energetic h5 low approaches the Deep South. The atmos will remain quite dry Fri as broad Canadian sfc hipres continues to ridge across the FA from the NW. This high will keep winds aligned n/ly and add a component of downslope warming and combine with a good insol heating potential. Max temps have been adj up a little and with deeper mixing, expect sfc td/s to lower more during the afternoon into the lower 20s and possibly upper teens over most areas. Surface winds will remain low-end, likely below 10 mph most locales, so it looks like another day of elevated fire danger, esp across NE GA, as RH values lower below 25%. The upper low crosses overhead Fri night and don/t expect much fanfare outside of increased cloudiness with stronger and gustier winds across the mtn ridgetops. The cloud cover will scatter out fairly quickly Sat and allow good insol once again in the afternoon. However, the cooler Canadian sfc high will build further SE and help keep sfc temps a little below normal levels. Still expect dry conds with td/s in the teens to l20s, but with the cooler temps, RH values will shud hold up a bit from Fri/s values with readings lowering into the mid to upper 20s . and thus close to fire-wx concerns.
LONG TERM /SUNDAY THROUGH WEDNESDAY/. As of 300 AM Thursday . A dry ulvl trof will swing over the area Sun followed closely by a building and strong h5 ridge. This ridge will slowly cross the east coast through the period and maintain broad and dry sfc hipres across the FA thru Day 7. A loosely supported cold front will likely weaken and become moisture limited as it approaches the NC mtns Wed night, so PoPs have been lowered and timed slower for this possibility. Afternoon sfc td/s will still remain quite low Sun and Mon with RH values coming close to elevated fire danger, however, winds become more sw/ly on Tue which will instigate a measure of llvl moist adv and thus RH values shud remain abv fire hazard criteria. However, any timing issues with the sfc front or large scale synoptic pattern that far out could change the degree of dryness actually realized. Max temps shud begin the period a little cooler than normal and rise into the u60s by Wed. Mins will also warm thru the period with lows beginning below normal and increasing to abt 10-15 degrees abv normal by Wed night.
AVIATION /09Z THURSDAY THROUGH MONDAY/. At KCLT and elsewhere: Mainly clear conditions are expected across the terminal forecast area as deep layer northwest flow continues and a weak and dry cold front settles southward through the region today. Low end gusts will be possible through the afternoon hours with mixing, with gusts into the 20s across western NC. Any spotty upslope cloudiness near the TN border in the northwest flow should remain well west of KAVL. The gusts will abate tonight with continued clear skies under building surface high pressure and northwest flow.
Outlook: Very dry and VFR conditions will persist through at least Friday. A Gulf Coast low pressure system will likely pass south of the terminal area Friday night into Saturday before dry high pressure returns again for the latter half of the weekend into early next week.

FIRE WEATHER. Already dry profiles today will combine with northwesterly downsloping flow east of the mountains to dry the air out further, resulting in min RH values dipping into the upper teens and lower 20s in many areas east of the mountains this afternoon. With mixing, low end gusts to near 20 mph will be possible in some locations. Fuels continue to steadily dry out as well, with some RAWS sites indicating 10-hr moisture values dipping to 7 to 8 percent yesterday afternoon. A Fire Danger Statement could be needed today for mainly areas east of the mountains pending coordination with the land managers this morning. The statement has been issued already for northeast Georgia. Very dry conditions are expected again on Friday and Saturday.
