Area Forecast Discussion National Weather Service Raleigh NC 255 AM EST Wed Feb 19 2025
SYNOPSIS
High pressure will build across VA and NC this morning. Low pressure will track across and just offshore the Gulf and South Atlantic states later today and tonight. Arctic high pressure will follow and migrate from the northern Plains to the Middle Atlantic, while weakening and modifying, through the weekend.
NEAR TERM /THROUGH THURSDAY/
As of 255 AM Wednesday...
Low pressure is developing off the Louisiana coast and will be moving to the east at the same time that a second low will be developing off the Georgia coast and moving along the Atlantic coastline. It is notable that there is some convection currently occurring along the Gulf Coast, as previous research has shown that when convection occurs along the Gulf, it can interrupt moisture transport into the Carolinas. With the latest round of model guidance, there has been a slight reduction in the amount of liquid precipitation that will fall across the Carolinas, also resulting in a slight reduction in snow and freezing rain accumulation. No changes have been made to advisories or warnings, as the reduction in liquid precipitation was less to the east where the warnings are located. In the counties with advisories, the criteria of 1 inch of snow or any accumulation of freezing rain are still expected to be met.
The chance of precipitation is still expected to begin around daybreak across the northwest, slowly spread across the rest of the area, and quickly ramp up during the late morning and early afternoon hours. The highest accumulation is expected to happen during the afternoon, especially along and east of US-1. Counties along the northern tier of the forecast area are expected to remain all snow, with all other counties expected to receive a mix of snow, sleet, and freezing rain. The chance for liquid rain should remain mostly to the south of NC 24. The models have started to show a trend for precipitation to exit to the east slightly quicker. The official forecast maintains chance pops in the Triad into the evening hours, although precipitation may be east of the area by that time. The bulk of the precipitation will likely be to the east of I-95 by midnight, and many locations should have a several hour break in precipitation overnight. However, there is greater consistency in showing a round of snow moving through many locations Thursday morning with an upper low that will pass along the Mason- Dixon line. This snow should be light, but could result in a couple tenths of additional snow during the Thursday morning commute. All snow should move to the east of central NC by Thursday afternoon.
Daytime highs today will range from the upper 20s to the upper 30s, and will likely occur in the late morning, with evaporative cooling resulting in temperatures remaining steady or falling through the rest of the day. Lows tonight will be in the 20s. Highs on Thursday will range from the low 30s to the low 40s. Gusty winds are still expected on Thursday with an increased pressure gradient between the departing low over the Atlantic and high pressure that will dominate the central United States, but have slightly reduced the inherited forecast values. Still, gusts are likely to be anywhere from 25-35 mph across the region, with the highest values in the Triad.
SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/
As of 220 AM Wednesday...
* Very cold conditions Thursday and Friday nights with lows 14 to 20 degrees below average.
* Wind chill values on Friday morning will range between 10 and 15 degrees and they could briefly drop into the single digits.
Cold Arctic high pressure across the central Plains on Thursday evening will extend into the middle Atlantic through early Saturday morning. The combined circulation around the high and the departing winter storm with result in a period of cold advection and very cold conditions. Low level thickness values are forecast to drop into the 1260's on Friday morning supporting lows in the mid teens to around 20 degrees. These temperatures combined a northwest wind of 5 to 10 mph will result in wind chills values of 10 to 15 degrees which may briefly drop into the single digits Friday morning.
Expect cold and fair weather on Friday with bright sunshine and chilly temperatures. Highs in the in the northern Coastal Plain and VA border counties will likely be chilled by snow/ice cover and melting with highs in the upper 30s. Most other locations will have highs in the lower 40s. These highs are 12 to 20 degrees below average.
Another chilly night is expected on Friday night. A northern stream wave will approach from the MO/OH Valleys and could result in some increased high clouds. Low level thickness values will warm 20 to 25m from the previous 24 hours. This should result in a night that wont be as cold as Thursday night but with a shallow cold airmass in place lows should range in the upper teens to lower 20s. -Blaes
LONG TERM /SATURDAY THROUGH TUESDAY/
As of 250 AM Wednesday...
NWP guidance notes that a mid and upper level short wave trough will move from the TN Valley on Saturday morning and off the Carolina coast on Saturday night. This feature has limited moisture but some guidance notes that a surface reflection may develop near and just off the Southeast coast on Sunday morning before moving northeast away from area on Sunday night. Our forecast increased cloud cover across the area for Saturday into early Monday but given most of the forcing for ascent is off the coast and just about every member of the latest GFE and EC ensembles note no precipitation, will keep the forecast dry. A generally fair and dry northwest flow is expected for late Sunday into late Monday. There is a signal for perturbations in the northwest and westerly flow to approach or move into the area for late Tuesday and into Wednesday. Guidance is all of the place with how this will shake out but a handful of GFS/EC ensemble members producing light precipitation for late Tuesday and Wednesday.
Given the uncertainty will keep the forecast dry. Temperatures should generally moderate through the period with highs in the 40s to near 50 on Saturday moderating into the lower to mid 50s on Sunday and the lower to mid 60s on Tuesday. -Blaes
AVIATION /08Z WEDNESDAY THROUGH SUNDAY/
As of 125 AM Wednesday...
Initially VFR conditions will deteriorate to MVFR and potentially IFR Wednesday late morning through afternoon, then remain so through the end of the TAF period, as low pressure gathers strength off the coast of the Carolinas and precipitation overspreads the region.
Additionally, light nely surface winds early this morning will strengthen and become at least occasionally gusty with the passage of a backdoor cold front from northeast to southwest between ~10- 15Z, prior to the onset of precipitation and flight restrictions.
With respect to precipitation types, all will be possible over central NC, including all or mainly snow over the Piedmont (RDU/GSO/INT), mainly freezing rain at FAY, and a mix of snow, sleet, and freezing rain at RWI. Near the end of the TAF period, all precipitation may taper to light freezing rain/freezing drizzle, when lift will diminish and the cloud layer may become dominated by supercooled water versus ice.
Outlook: MVFR/potential IFR conditions should continue Wed night-Thu morning. Light snow will probably redevelop with the passage of a vigorous mid/upr-level trough early Thu, before skies clear and nwly surface winds strengthen and become gusty during the afternoon.
