As of 210 PM Wednesday... 1) The potential for record heat continues through Friday. 2) A cold front Friday night brings a decisive end to the record heat, bringing in well below normal temperatures for the weekend and the potential for patchy frost by Sunday morning. && .DISCUSSION... As of 210 PM Wednesday... KEY MESSAGE 1... The potential for record heat continues through Friday. As of 2pm, RDU had already warmed to 88 degrees, beating the previous daily record high of 86 set in 1985. In addition, GSO had warmed to 85 degrees, tying the daily record high set in 1975. FAY is 87 degrees and will flirt with their daily record high of 90 degrees. This is primarily due to an upper-level ridge building across the southeastern United States, considering surface wind has been minimal out of the southwest today. The potential for record heat on Thursday may be tempered by a cold front currently near the Mason-Dixon line that will drop south tomorrow into Virginia, and some models are showing this front drifting into northeastern North Carolina. There will likely be a 10 degree difference in high temperatures between Raleigh and Roanoke Rapids Thursday afternoon, although all three climate sites (Greensboro, RDU, Fayetteville) are expected to remain on the warm side of the front. Precipitation chances with this front are near zero, but the front will retreat to the north on Friday, allowing the entire forecast area to return to the mid to upper 80s for highs. Along with widespread sunshine on Friday, wind gusts as high as 30 mph can be expected in the afternoon. KEY MESSAGE 2... A cold front Friday night brings a decisive end to the record heat, bringing in well below normal temperatures for the weekend and the potential for patchy frost by Sunday morning. The cold front is expected to arrive slightly later than the previous forecast, and should now be crossing central North Carolina after sunset Friday evening. Although winds could be gusty with the frontal passage itself, this timing will reduce the overall wind gusts due to less mixing in the overnight hours. Models are showing a noticeable increase for the chance of rain with the frontal passage, specifically looking at Saturday morning, although rainfall totals would not be heavy. Saturday's highs will be 20 to 25 degrees colder than Friday, with isolated colder spots only rising into the upper 50s, with most locations reaching the low to mid 60s. Saturday and Sunday nights should have similar low temperatures, with most locations falling into the 40s, but some sheltered locations dropping into the upper 30s with the potential for some frost. Temperatures should return to near normal values by the beginning of next week, with highs around 70 and lows around 50. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... As of 155 AM Thursday... Light swly winds will persist ahead of an outflow boundary that may shift surface winds to light nely/ely at Piedmont sites and RWI late this morning. That boundary will be followed by a backdoor cold front that will settle into the far ne Piedmont and nrn Coastal Plain of NC late this afternoon or this evening. IFR-MVFR ceilings are likely to develop behind that front, including at RWI, near the end of the 06Z TAF period. While the front and post-frontal ceilings are likely to hold just to the north of Piedmont sites, by perhaps 10-30 miles, a slight swwd shift of the location of the boundary would result in an increasing likelihood for flight restrictions at Piedmont sites tonight as well. Outlook: Gusty swly surface winds will develop ahead of a strong cold front on Fri, followed by a period of strong and gusty nwly surface winds with the passage of that front Fri night. There is a chance that the front will be accompanied by a shallow, broken line of convection (devoid of lightning) as it moves across cntl NC Fri night, followed by an area of post-frontal, stratiform rain that may linger into the day Sat. && .CLIMATE...
