High pressure will be overhead this morning with clear skies and light wind. Temperatures will dip into the mid 30s with scattered frost in outlying areas. The high pressure will shift to our SE this afternoon allowing a return SW flow at 10 to 15 mph. Highs will moderate to around 70 for all areas. A dry front will approach from the NW late tonight. There will be some increase in clouds tonight, with a period of mostly cloudy skies expected late tonight over the Piedmont. Lows will be in the upper 40s and lower 50s.

&& .SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/...
-- Changed Discussion --
As of 232 AM Tuesday... The dry cold front will move across the area on Wednesday. It will actually be warmer on Wednesday with a pre-dominantly westerly flow becoming northwest. The CAA will be delayed until Wednesday night. A period of cloudy skies will likely accompany the front during the morning into the early afternoon. A sprinkle can not be ruled out although no QFP is currently advertised. Otherwise, the skies are expected to become partly sunny Wednesday afternoon. Highs should range in the 70s. It will be cooler Wednesday night with the flow becoming more NE. Models and soundings suggest partly to mostly cloudy periods on Wednesday night. Lows in the 40s to lower 50s SE.

&& .LONG TERM /WEDNESDAY THROUGH MONDAY/... As of 241 PM Monday... An upper level trough will swing across the Northeast Wednesday morning followed by a weak shortwave swinging across the northern Mid-Atlantic region Wednesday night. By Friday, upper level ridging will take over through the weekend resulting in fair weather for the latter half of the long term period. At the surface, a low pressure system centered over the southern portions of Quebec early Wednesday morning will trail a cold front south along the Appalachian Mountains. While showers will be persistent west and north of the mountains latest model guidance is showing much of the forcing loosing energy east of the mountain range thus limiting the chance for rain across Central NC. Expect some passing sprinkles Wednesday afternoon as the front moves across the region. As the front moves offshore overnight, a cool dry high pressure will build into the region with northeasterly winds taking over. If conditions clear out early enough Thursday morning, light NE winds could help result in some patchy fog across portions of the NE Piedmont and Coastal Plain. Thursday and Friday are expected to be fair weather days with mostly sunny skies and temps in the upper 60s north, to low/mid 70s across the south. As high pressure and upper level ridging strengthens across our region over the weekend and early next week temperatures are expected to increase quickly with highs in the mid/upper 70s Saturday, low to mid 80s Sunday, then by Monday mid 80s across the entire region. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... As of 135 AM Tuesday... 24 hour TAF period: High confidence VFR conditions will prevail through the TAF period. Expect clear skies and calm to light winds overnight, with continued clear skies and winds increasing from NW to SE through the afternoon Tuesday. Outlook: Largely VFR conditions are expected through Sat. There are two possible exceptions. First would be a small chance for a brief period of light showers/sprinkles and/or borderline VFR/MVFR cigs as a weak cold front moves into/through the area on Wednesday. The other would be a possible brief period of borderline VFR/MVFR cigs Thu morn/early aft. However, confidence in both occurrences of restrictions remains low at this time. && .RAH WATCHES/WARNINGS/ADVISORIES...
