AREA FORECAST DISCUSSION National Weather Service Raleigh NC 657 PM EST Sun Jan 16 2022

SYNOPSIS. Low pressure will exit the Carolinas tonight. High pressure will build over the Southeast, ridging into central NC through Tuesday.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. As of 600 PM Sunday .

The Winter Storm Warning continues across portions of the NC Piedmont for sleet, freezing rain or icy road conditions.

Surface observations showed a 996 mb low moving NE along the I-95 corridor, and another 997 mb low along the Blue Ridge. Radar displayed scattered showers across portions of the northern Piedmont, and heavy rain moving northeast across the northern Coastal Plain. The Winter Storm Warning has been canceled for areas south and east where precipitation has ended and the surface temp is above freezing, however the warning will continue where mixed precipitation is still falling and/or icy roads remain a hazard. Although the main band of precip from the surface low will soon exit the region, an upper-level low moving northeast across the western half of the state early tonight will generate light rain/snow showers for some areas, with little accumulations expected. Latest high-res models show the best chance for rain/snow over and west of Highway 1, with rain to the east. Southwesterly wind gusts to 30 mph are possible tonight along the Coastal Plain as the upper-level low moves by and the surface low departs the region.

Even when precipitation ends tonight, black ice will remain a hazard for many locations. Updated lows for tonight show areas west of I-95 dipping at or below freezing. Additional analysis this evening will determine if and when a Winter Weather Advisory will be needed for black ice.

SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/. As of 155 PM Sunday .

A vigorous shortwave trough in nwly flow aloft now digging sewd across the nrn Plains will have reached the lwr OH ands TN Valleys by 12Z Mon, in short wavelength flow between it and the powerful tropospheric-deep cyclone lifting newd across the srn Appalachians. That trough will then pivot ewd across the Carolinas/srn Mid Atlantic through 00-03Z Tue, with associated height falls and a mid/upper-level front that will contribute to modest lift centered around 500 mb over cntl NC between 15-21Z Mon. Although an associated period of mostly cloudy conditions and virga will likely result, especially across the Piedmont, it should remain dry at the surface owing to considerable sub-cloud dryness below 700 mb. Some of that virga may, however, diabatically-enhance already strong wly winds in a well-mixed, ~3000 ft AGL deep boundary layer behind a sub- 980 mb low lifting across the nrn Mid Atlantic and Northeast, with associated surface gusts around 30 kts and blustery conditions across cntl NC from mid-morning through the afternoon. Otherwise, high temperatures will be about 10 F below average, in the upr 30s to mid 40s, with associated wind chill values about 10 F chillier.

Height rises in nwly flow aloft will follow for later Mon night through Tue, before backing to swly ahead of the next shortwave trough forecast to dig sewd out of the Canadian Prairies Tue night. Underlying continental Polar surface high pressure will build across and offshore the Southeast during this time, with continued below average temperatures in the lwr-mid 20s Mon night and mid-upr 20s Tue night, and highs Tue in the 40s. While it should otherwise be mainly clear, periods of high level cloudiness are likely Tue morning and especially Tue night, along with areas of low stratus and fog over the nw Piedmont Wed morning.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. As of 345 PM Sunday .

While confidence is high that ridging will develop and expand nwd along the West Coast through next weekend, with downstream troughing over the ern US, there remains significant model spread in individual shortwave details. Forecast confidence consequently decreases with time during the medium range, with even larger model spread today than yesterday regarding at least one episode of cyclogenesis along a wavy Arctic front forecast to cross the Carolinas late Wed night-Thu, then become quasi-stationary from the wrn Atlantic to the Gulf of Mexico through the remainder of the forecast period.

Of greatest confidence is a warm-up ahead of that Arctic front, mostly into the 50s on Wed, though with some lingering 40s maintained by low overcast over the nw Piedmont. A band of rain/showers with generally a quarter to third of an inch will also likely accompany the frontal zone, supported aloft by the deamplifying remains of a mid/upper-level srn stream low now spinning off the coast of srn CA.

Following Arctic high pressure will sprawl ewd from the nrn Plains to the Northeast and Mid Atlantic, with what may be the coldest airmass of the season for cntl NC by Fri through the weekend. It will be the srn extent of that Arctic drape, where both isentropic lift and cyclogenesis may become energized by the aforementioned low predictability shortwave troughs aloft, where precipitation -- including wintry on the poleward side-- will be possible, including near or just southeast of cntl NC. To reiterate, those details and the sensible weather impacts, with the threat of precipitation spreading nwd into the Arctic air, remain highly uncertain - but a possibility worth monitoring as those details are hopefully resolved during the coming days.

AVIATION /00Z MONDAY THROUGH FRIDAY/. As of 640 PM Sunday .

Generally IFR flight conditions are expected across cntl NC through most of this evening, as a strengthening low pressure tracks newd across the region. While the shield of steadier and heavier precipitation has moved NE, a trailing mid/upper- level disturbance may result in a few hour period of light snow NW and light rain SE throughout cntl NC this evening. Southwest to northeast scattering to VFR will occur as the low pressure lifts newd and away from cntl NC late tonight-Mon morning; and that clearing will also be accompanied by strengthening and increasingly-gusty swly to wly surface winds that will continue through the end of the 00Z/Mon TAF period.

Outlook: Areas of fog and low stratus are expected to develop across the NC Foothills and wrn Piedmont Wed morning, followed by rain and sub-VFR conditions along and ahead of a cold front Wed night-early Thu. Although forecast confidence is low, there will be another chance of wintry precipitation and sub-VFR conditions late in the week.

RAH WATCHES/WARNINGS/ADVISORIES. Winter Storm Warning until midnight EST tonight for NCZ007>010- 021>025-038>040.
