AREA FORECAST DISCUSSION National Weather Service Raleigh NC 1045 AM EDT Sat Mar 28 2020

SYNOPSIS. A warm front over northeastern NC will move north into VA this afternoon. A strong high pressure aloft will extend over the state through the weekend, bringing an early season hot spell. A cold front will push southeast through the area Sunday night, bringing cooler temperatures for Monday and Tuesday.

NEAR TERM /TODAY AND TONIGHT/. As of 1045 AM Saturday .

. Record heat for some locations this afternoon .

The warm front over NE North Carolina is now lifting northward. It will be in southern VA this afternoon. The low level stratus that extended across the northern Piedmont including NE Forsyth, northern Guilford, northern Orange to Granville and Warren counties was finally dissolving as the SW flow and top down drying increase. All of our region will be in the warm sector this afternoon with mostly sunny skies and rapidly warming temperatures. Records will likely be challenged or broken at Fayetteville and Lumberton. Others may be challenged. The list of records is in the climate section below. Expect highs this afternoon of 85-90.

Mostly clear skies will continue tonight beneath the building ridge aloft. Expect unseasonably warm lows in the 60s with a light SW breeze.

SHORT TERM /SUNDAY AND SUNDAY NIGHT/. As of 310 AM Saturday .

WAA will persist and strengthen Sun, maintaining very warm temps, peaking again in the mid-upper 80s, as thicknesses are expected to start the day around 60 m above normal once again. The onset of mixing by mid morning coupled with 25-40 kt SW winds through the 2000-5000 ft depth will yield breezy conditions with gusts frequently exceeding 25 mph. A cold front approaching from the W Sun will be associated with a deep mid-upper level low tracking NE over WI and MI into Ont/Que. The front is expected to move into the S Appalachians Sun evening before slowly working SE into central and NE NC just before daybreak Mon. The forward progression of this front will be hindered by not only the inability of the denser air to get past the higher terrain but also the tendency of the steering flow to become oriented roughly parallel to the surface front, limiting its ESE push. As such, expect temps to remain mild through Sun night, with lows in the mid 50s to lower 60s (and even these mid- upper 50s readings in the W CWA may be too cool). Regarding precip chances, despite the SW flow ahead of the front, the overall forcing for ascent will be waning with drying mid levels. Of the available ensemble systems, only a few members show any measurable precip over central NC, and probabilities of measurable precip are very low even in the Triad and near zero elsewhere. Have held onto an isolated pop in Forsyth late Sun, but otherwise will keep the forecast dry. -GIH

LONG TERM /MONDAY THROUGH FRIDAY/. As of 220 AM Saturday .

Monday through Wednesday: A low pressure system will develop off the Rockies on Monday and swing through the Plains and MS Valley through Tuesday. This low will open as it lifts north through the OH Valley and into the mid-Atlantic, becoming absorbed into the larger scale low as a shortwave Tuesday night/Wednesday. The parent upper low will sit over the Northeast US/SE Canada as the shortwave moves through the region. The low will continue its eastward progression off the mid-Atlantic coast and over the Atlantic on Wednesday. Meanwhile, the surface low that develops in response to the upper low off the eastern Rockies on Monday will progress almost due east through the Plains and Southern MS Valley and into the TN Valley by Tuesday. Models continue to suggest that the preceding warm front will remain south of the area through Tuesday afternoon as high pressure tries to ridge southward into the region from Canada. As the surface low continues to push east Tuesday afternoon, the original low will split into two lows, one lifting northeast along the Appalachians and the second, which becomes the dominant low, swinging around the southern Appalachians and through the Southeast US. For now the low is expected to lift northeast through SC and eastern NC Tuesday eve/night while the warm front tries to lift into southern portions of NC. The temperature and precipitation will depend greatly on the track this low takes, but generally expect the highest, more convective rainfall amounts farther south and east with more stratiform precipitation falling on the cool side of the front. Likewise, temperatures should be highest south and east, lowest northwest. Generally expect above normal temperatures on Monday, decreasing through Tuesday night. Based on current timing, dry weather should return Wednesday night as the low lifts away from the region.

Thursday and Friday: Dry weather and seasonable temperatures should persist through at least Friday night, however the medium-range models vary significantly and thus forecast confidence is low at this time.

AVIATION /16Z SATURDAY THROUGH WEDNESDAY/. As of 1045 AM Saturday .

VFR conditions will be prevalent across much of central NC over the next 24 hours.

Looking beyond 12z Sun, VFR conditions will dominate for the next few days, although there is a chance for brief MVFR conditions in an isolated storm near INT/GSO late Sun or Sun evening, ahead of a cold front that will move through Sun night. VFR conditions should hold through the first part of Tue, but an approaching storm system from the west will bring a good chance of sub-VFR conditions in rain Tue afternoon through Wed. -GIH

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
