AREA FORECAST DISCUSSION National Weather Service Raleigh NC 151 PM EDT Thu Sep 23 2021

SYNOPSIS. A cold front over eastern NC will move slowly eastward and offshore the Outer Banks tonight. High pressure will follow and build from the mid-South to the middle Atlantic through Saturday. A dry, secondary cold front will cross the region Saturday night.

NEAR TERM /THROUGH TONIGHT/. As of 1020 AM Thursday .

The surface cold front has cleared all of cntl NC and stretched at 14Z from the nrn Chesapeake Bay sswwd across the Tidewater of VA/NC and off the coast of NC near Bald Head Island. While the deepest convection will remain along and east of the front, a plume of anafrontal showers will trail the front in a regime of continued moist, sly flow above 850 mb and beneath deep layer forcing for ascent on the sern periphery of a mid/upper-level cyclone centered over sern Lower MI and nwrn OH. Those showers may continue to skirt the far eastern portions of Edgecombe and Halifax Co. for the next couple of hours.

Mainly cosmetic and timing updates were made to the gridded forecast, which included maintaining a lingering small chance of the aforementioned anafrontal showers near and east of Scotland Neck and Conetoe.

PREV DISCUSSION. /ISSUED 345 AM EDT Thu Sep 23 2021/

The upper-level low over the Ohio Valley will move slowly NEWD through the Great Lakes region through tonight. The attendant sfc cold front and accompanying line of convection will exit the coastal plain counties ~09z. While the passage of the cold front will bring an end to rain chances across the area, the lingering low-level cloud cover will not be as quick to clear out, thanks to the continued SELY H8 flow that will persist until the passage of the h8 trough 18z. The delayed passage of the H8 trough also means that the best cold dry air advection will not take place until the evening and overnight hour, as a ~1020mb surface builds into the southern Appalachians.

Highs ranging from lower/mid 70s north to near 80 SE. Min temps Friday morning will be the 1st time since spring that many locations over the NC Piedmont cool down into the 40s, so have those jackets/sweaters handy. Lows ranging from mid/upper 40s north to lower/mid 50s SE.

SHORT TERM /FRIDAY AND FRIDAY NIGHT/. As of 345 AM Thursday .

Upper level low over the Great Lakes will continue into Ontario and Quebec through the period. However, the main weather story will be the arrival of Fall, at least for a few days as sfc high pressure settles over the area. Temperatures will average 3 to 6 degrees below normal, while 40 degree dewpoints will bring a crispness to the air. Highs in the 70s.

A secondary, robust northern stream shortwave trough diving SEWD into the northern/central MS Valley could possibly bring some high clouds into the area late Friday night. Otherwise, cool with lows once again dipping down into the mid to upper 40s across the Piedmont, with some lower 50s across the southern/southeastern counties.

LONG TERM /SATURDAY THROUGH WEDNESDAY/. As of 345 AM Thursday .

Dry weather is expected for the long term as a surface high is centered across the Mid-Atlantic region Saturday and continues over the weekend and into early next week.

Aloft, an upper level trough will swing across the northern US over the weekend clipping central NC over the weekend. This is followed by a shortwave trough moving southeast over the region Monday into early Tuesday. It will be dry, but an increase in cloud cover is expected with upper level disturbances moving across the region. Forecast uncertainty increases Tuesday onward as model guidance diverges significantly. Long range models show another trough moving across the Mid-Atlantic but the ECMWF shows a much stronger and deeper trough bringing chances of rain for mid week, while the GFS shows a shortwave much weaker and more north, resulting in no rain for the region. Will have to watch closely as time comes closer, and there is more model agreement.

Temperatures start off below normal on Saturday with highs in the mid 70s NW to low 80s SE and lows in the low 50s in the NW to mid 50s SE. Temperatures then slowly increase to above normal for the remainder of the period with highs in the low 80s NW/ upper 80s SE Monday through Wednesday.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. As of 145 PM Thursday .

A cold front now moving slowly ewd across far ern NC has ushered high pressure and associated much drier air and VFR conditions into cntl NC; and these VFR conditions are expected to continue through the 18Z TAF period. There may be a brief period of relatively stronger and occasionally gusty surface winds into the teens kts this afternoon and again early Friday, with otherwise light to calm ones, as the center of the aforementioned high builds into the cntl Appalachians and Middle Atlantic.

Outlook: High pressure and associated dry air will favor VFR conditions in cntl NC through Tue.

RAH WATCHES/WARNINGS/ADVISORIES. None.
