AREA FORECAST DISCUSSION National Weather Service Raleigh NC 245 PM EDT Mon Apr 19 2021

SYNOPSIS. Weak high pressure will move over the southeastern United States tonight and persist into Tuesday. A cold front will bring a small chance of rain Wednesday, but will be more noteworthy for bringing much colder temperatures Wednesday night through Thursday night.

NEAR TERM /TONIGHT/. As of 245 PM Monday .

At upper levels, a shortwave is currently sliding across the Mid- Atlantic states, extending south across central Virginia and central North Carolina. At the surface, low pressure is near Cape Hatteras, beginning to move offshore. The upper level shortwave has been responsible for the scattered showers and isolated thunderstorms moving through the region, and any remaining showers will come to an end by sunset as high pressure moves in at the surface. Skies will be mostly clear tonight, and while winds will be light, there should be enough wind to limit radiational cooling. Lows are expected to be in the 40s across the area, but in any location where winds go calm, temperatures could certainly drop a few extra degrees.

SHORT TERM /TUESDAY AND TUESDAY NIGHT/. As of 245 PM Monday .

Skies will be partly to mostly sunny on Tuesday with high pressure over the state, although some passing high clouds are expected. Low pressure will deepen over the Plains Tuesday, reaching eastern Kentucky by Tuesday night and moving into central Pennsylvania by Wednesday morning. Models continue to show that the best dynamics with this system will remain closer to the low center, allowing the region to remain mostly dry Tuesday night. However, a new wrinkle in the 12Z guidance is that the GFS, NAM, and SREF (but not the Euro) are all showing a small area of rain developing over the Carolinas in advance of the low pressure's cold front, the rain coming as the result of an upper level shortwave. Since this has not been shown in previous runs, have decided to only add a slight chance of showers after midnight for now and will allow later shifts to see whether this is a one-off occurrence, but the fact that the feature is shown in multiple models does lend it some credence. Highs will be slightly above normal, in the mid 70s, with lows in the lower 50s.

LONG TERM /WEDNESDAY THROUGH MONDAY/. As of 245 PM Monday .

As stated previously, a cold front will be west of the region Wednesday morning, but the front will move through during the day. With the best forcing north of the region, have primarily stuck with slight chance pops, but did add some chance pops northeast of Raleigh during the afternoon. Also, with some modest instability, did add a slight chance of thunderstorms with the chance of showers. As noted in the midnight forecast discussion, RH values will drop behind the front and there will be a stiff increase in winds, with sustained winds of 15-20 mph and gusts up to 25 mph, which could cause fire weather concerns.

High pressure will then dominate the weather for the end of the work week, resulting in two cold nights Wednesday and Thursday. Have undercut guidance, and still feel that a frost advisory will likely be needed for several areas, although it is still a little early for this issuance. An isolated freezing temperature cannot be ruled out if winds go completely calm. Highs on Thursday will drop into the 60s, and might not reach 60 near the Virginia border, but will recover towards 70 degrees on Friday.

The best chance of rain over the next 7 days will come this weekend with another system developing in the Plains and moving east. The bulk of the rain will be in advance of the low, which will be in east Texas Saturday morning but will race to the East Coast by Sunday morning and continue offshore. While rain will move into western counties Saturday morning, Saturday afternoon and evening appear to be the wettest time period, with likely pops throughout. An isolated shower cannot be ruled out Sunday morning, but skies should be clearing out by Sunday afternoon and mostly clear for Sunday night and Monday. The cloud cover will keep highs around 70 degrees Saturday and Sunday, with increasing temperatures on Monday with the return of widespread sunshine.

AVIATION /18Z MONDAY THROUGH SATURDAY/. As of 150 PM Monday .

An area of scattered showers and isolated thunderstorms and their associated MVFR restrictions will continue to move east and will exit the eastern TAF sites between 20 to 21z. Mostly clear skies will develop by this evening and continue tonight, with the potential for some patchy fog development, mainly across the NE, near KRWI and possibly KRDU, between 06 to 12z Tue. Otherwise, expect VFR conditions with the TAF period with winds veering from NNWLY this afternoon to SSWLY during the day on Tuesday.

Outlook: A strong but moisture-deprived cold front will bring a very small/isolated chance of showers/storms on Wednesday, along with a period of gusty winds ahead of(SWLY) and behind(NWLY)the front. Dry VFR conditions are expected Thursday and Friday. An area of low pressure tracking from the lower Mississippi Valley into the Southeast will bring widespread rain/storms chances and associated sub-VFR restrictions Saturday through early Sunday.

RAH WATCHES/WARNINGS/ADVISORIES. None.
