283 FXUS62 KRAH 101954 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 254 PM EST Mon Nov 10 2025 .SYNOPSIS... A very strong upper level trough and Arctic cold front will cross the region this afternoon through tonight. This upper level trough will push off the East Coast Tuesday, allowing for a gradual warmup back to near normal temperatures by Thursday. && .NEAR TERM /THROUGH TONIGHT/... As of 252 PM Monday... * A hard freeze tonight will end the growing season. * A record strong and cold upper level trough will bring a chance of light snow and flurries mainly along and north of Hwy 64 this evening into the overnight hours. * Strong blustery winds tonight/Tuesday morning will produce wind chills in the teens. The anomalous mid-level low continues to spiral and slide south over the TN Valley generating accumulating snow along the western slopes of the southern Appalachians. Here locally, were locked into post- frontal wnwly low-level flow with temps largely in the mid 40s to lower 50s. Starting to see some cooler temps near and entering our western Piedmont, with dew points in this vicinity crashing into the mid to upper teens. Expect wnwly gusts of 20 to 30 mph to continue through this afternoon and overnight, with a secondary surge possible through sunrise Tuesday. The Freeze Warning remains in effect as all signs signal a good chance for several hours of sub-freezing temperatures everywhere tonight. The strength of this mid-upper low is quite anomalous, as temps and heights from 1000 to 500 mb are projected to be below the 1st percentile compared to climatology as it moves over us. Low- level thicknesses Tuesday morning will drop well into the 1260 to 1270m range, easily supportive of sub-freezing temps. All in all, lows overnight will dip into the mid to upper 20s, with upper teen wind chills possible given the gustiness overnight. High-res guidance continues to suggest a chance for a brief period of flurries or light snow mainly along and north of Hwy 64 early tonight through the overnight hours. Overall saturation depth through the dendritic growth zone is limited, but enough there to generate snow aloft. However, forecast soundings continue to show a decent low-level sub-cloud dry layer. As such, much of this snow may very well never reach the sfc and instead fall as virga. This is especially true for areas further south. The HRRR, for example, continues to suggest a light snow band over the southern Piedmont/Sandhills early this evening. Forecast soundings in this time frame and location depict a deeper dry layer compared to areas further north later tonight when the second band moves across central NC. Regardless of how much light snow reaches the sfc, the overall message remains the same that no hazardous weather is expected as ground temps will be far too warm (in addition to drying nwly flow) for accumulation (other than perhaps isolated elevated surfaces could see a dusting). && .SHORT TERM /TUESDAY AND TUESDAY NIGHT/... As of 252 PM Monday... Low pressure along the cold front that went through last night will have pushed north into eastern Canada while high pressure will slide east along the Gulf Coast. Despite the front being well offshore, there will still be a modest pressure gradient between the Gulf high and the Canadian low, keeping sustained wind around 10 mph and gusts around 20 mph. Air with dewpoints well below freezing will move into the area today and remain on Tuesday, with widespread dewpoints in the teens. Fire weather concerns are possible with the higher winds and dry air, although air temperatures will be quite cool. Tuesday will be the coldest day out of the next seven for most locations, although highs will be similar today and tomorrow in the Triad, and it does not appear temperatures anywhere will rise out of the 40s tomorrow. As the wind shifts to the southwest Tuesday night, this should moderate overnight lows slightly from tonight, although many places will still drop to around 30 degrees. Nevertheless, the growing season is still expected to come to an end in all locations tonight. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... As of 252 PM Monday... While a cold front will come through on Wednesday, very dry air should prevent any precipitation from occurring, with even cloud cover minimal along the frontal passage. The wind values on Wednesday will be similar to Tuesday, with the sustained wind around 10 mph and gusts around 20 mph. Fire weather concerns could persist with the higher winds. With high pressure across the southeastern United States through much of the week, there will not be a chance for precipitation until Sunday at the earliest, and models are suggesting that the better chance for precipitation won`t come until Monday. Low pressure is likely to move over New England, dragging a cold front across the Appalachians Monday. As the wind shifts to the southwest on Wednesday, this should moderate temperatures, and most locations should return to the low 60s by Wednesday. By the weekend, some 70s will return. Lows will be in the upper 30s and 40s. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... As of 214 PM Monday... VFR conditions will largely prevail through the 24 hour TAF period. The only caveat is that there still looks to be a chance for brief restrictions from passing snow showers at KINT/KGSO/KRDU/KRWI later tonight. There is a decent dry layer near the sfc, so not entirely sure we`ll see actual snow at the terminals or just virga aloft. However, if it does reach the sfc, expect brief reductions in visibilities at these terminals tonight. Any lingering snow showers should move east of central NC through sunrise Tuesday morning. Otherwise, expect 20 to 30 kt gusts to persist this afternoon and into the overnight hours through the end of the TAF period. Looking beyond 18z Tue, VFR conditions should prevail at all sites through Fri. Winds will again be gusty from late morning through afternoon Tue from the WNW, and on Wed from the WSW. -GIH && .RAH WATCHES/WARNINGS/ADVISORIES...
