SYNOPSIS. High pressure will control our weather through the better part of the week. A warming trend will continue until Friday, which will be an exceptionally warm day. A dry cold front will pass this weekend, with the next good chance for rainfall not arriving until next week.

NEAR TERM /THROUGH WEDNESDAY/. As of 625 PM EST Tuesday: Sat pix showing cirrus beginning to move in from the NW. Expect this to continue through the night with some potential for periods of broken coverage with mountain wave action. Winds become light and variable to calm with some wind lingering over the ridge tops. Lows will be near to a few degrees below normal.

Shortwave trough will approach the CFWA from the northwest during the day on Wednesday. This will gradually push better coverage of mid to high clouds into the area during the day as better moisture filters into the mid/upper levels of the atmosphere. The best synoptic forcing associated with the trough will remain to the north, so the forecast will remain dry. Some of the CAMs produce very light precip over the far northern tier, but the environment will be so dry that if anything falls out of the sky will most likely evaporate before making it to the surface. Global models have a completely dry forecast, but have hinted at some of the better forcing dwindling down into the northern mountains and producing very light precip by the very end of the forecast period. Temperatures will be too warm to support anything other than rain. Expect Wednesday's highs to be 4 to 8 degrees above normal, but could become tricky if the cloud cover associated with the shortwave reaches the area earlier than forecasted.

SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/. As of noon Tuesday: A shortwave will provide a fleeting shot of forcing to the CWA Wednesday evening. A saturated layer is seen in prog soundings above 700 mb, but below that level it appears generally too dry to advertise any PoP with the wave itself. W to NW flow will develop behind that wave, downstream of a flat ridge generally extending back to the Intermountain West. Shallow moisture will bank against the Appalachians near the TN/NC border Wed night and early Thursday. However, the moist layer should be insufficient for anything but perhaps a few sprinkles; sfc temps look likely to be too warm for flurries even if the ice nuclei were present aloft.

850mb height rises Thu into Fri reflect the modification of the dry high pressure lingering over the Southeast, and suggest a continued rebound in temps thru the short term period. Max temps are expected 17-20 degrees above normal Friday. Based on 50th percentile of available guidance, we stand a chance of tying the record high at our climate sites; wouldn't be surprising to go closer to 75th percentile on a sunny day, so we could even break a record. Owing to the tight height gradient downstream of the ridge, higher elevations may be subject to brisk winds at times early Friday, but mixing will be kept in check by the subsidence aloft. The timing of the winds and generally more humid conditions persisting at those elevations suggest (fortunately) that fire danger does not look to spike as a result. That said, two more warm and dry days won't provide much relief to the already dry fuel and soil conditions.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. As of 130 PM Tue: Another moisture-starved cold front does look to encroach on the CWA Saturday, mainly having the impact of bringing a cool and dry airmass back to the region by Sunday. Temps will fall back to about normal, or only slightly above.

The model consensus supports an amplifying pattern across the CONUS early next week, which appears to provide our next hope for meaningful precipitation in the CWA. The feature of interest will be a shortwave digging from Canada into the northern tier of the CONUS. Models have not yet settled into strong consensus on where that occurs; the 30/12z GFS is a little more aggressive, seemingly as a result of the wave phasing with a disturbance near Arkansas, along the front. It spins up a deep surface low over the western Great Lakes on Sunday, whereas most other solutions (and GEFS members) show a low of similar magnitude developing closer to the East Coast. The timing isn't all that different, with peak PoPs suggested Monday morning. The GFS solution is considerably wetter and is the only model showing really any precip east of the mountains. Chance-range PoPs are forecast along the TN border, and no better than slight chance along/east of the Escarpment. The likelihood of a true wetting rain appears even smaller at this time.

RH and wind forecasts are not especially concerning for fire weather behind the front early next week, but the already low fuel moisture readings appear likely to trend still lower.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. At KCLT and elsewhere: VFR conditions are expected through the TAF period. Winds diminish this evening becoming light and variable to calm. Mainly high clouds will push into the area overnight into Wednesday. BKN mainly thin cirrus likely with mountain wave action developing. Winds pick up out of the SW through the day. KAVL the exception where they start N and turn S by afternoon.

Outlook: Dry high pressure and VFR conditions will persist through the week. Better moisture may enter the mountains over the weekend, but whether this will result in restrictions is questionable at best.

FIRE WEATHER. Dry conditions and low-end gusty SW winds will continue to produce an increased fire danger through this afternoon. Fuels will remain very dry on Wednesday despite the increase in RH values and lower winds. Thus, fire danger will remain elevated, and per coordination with neighboring NWS offices and land management partners, a Fire Danger Statement will remain in effect for all of our NC zones this afternoon and will be for Wednesday as well. The state of North Carolina continues a state wide burn ban until further notice.
