AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1029 PM EDT Wed Sep 22 2021

SYNOPSIS. A cold front will continue to approach the area from the west tonight, and will cross the region on Thursday. Canadian high pressure builds in from Friday into the upcoming weekend.

NEAR TERM /THROUGH THURSDAY/. As of 1030 PM EDT Wednesday .

The latest analysis shows 1003mb sfc low pressure over Lake Erie, with the associated cold front extending S along the Appalachians. Moist SSE llvl flow has pushed PWs of 1.90" to 2.10" into most of the CWA (values are still lower at the coast and eastern shore (1.50" to 1.70"). The local area is presently under a lull in rainfall as the earlier batch of showers and embedded tstms lifted N of the region and dissipated, and the main activity with the front is just beginning to nudge into the Piedmont late this evening. Warm, somewhat muggy, and breezy with temperatures ranging through the 70s and dewpoints are generally around 70F or into the lower 70s.

The core of the upper low cutoff over the OH Valley slowly north over the Great Lakes by tonight/early Thu. Attendant strong sfc low pressure becomes occluded over the Great Lakes, with a secondary trough of low pressure tracking E and crossing the local area during the day Thu. Will have lower PoPs through midnight, then ramping up overnight into Thu morning, categorical PoPs W and CHC to likely PoPs elsewhere overnight. The latest Day 1 ERO has expended the slight risk a bit farther to the E and now includes western sections of the CWA. It is also worth noting that the latest 12Z/HREF runs of 3-hr QPF amounts do not show much chance for 3"/3 hrs (less than 10%). Lows in the 60s to lower 70s.

Likely to categorical PoPs finally push east of the I95 corridor Thu morning into the aftn with the front slowly swinging through the region. SPC Marginal Convective Risk is over the northern neck and eastern shore for Thu, as the front pushes to the coast. Instability will be modest, but with height falls and markedly cooler air rushing in, some gusty winds in convection can obviously not be ruled out Thu. Will limit thunder chcs to I-95 and east late Thu morning into Thursday evening. Rain then tapers off inland Thu aftn. Highs in the low to mid 70s inland . 75 to 80 along the coast (though with falling temperatures near the coast in the aftn).

Additional total QPF ~1.00-1.50" out in the piedmont, tapering to ~1" RIC metro . to 0.50" to 1.00" east of I-95 to the coast. Again must be noted that significantly higher amounts possible, especially in potentially training heavy showers and storms.

SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/. As of 355 PM EDT Wednesday .

By Thu evening, much drier air will be over most of the region as the sfc cold front pushes off the coast. The front will linger just offshore into Fri morning however, so will keep some likely PoPs in the evening along the coast and eastern shore, gradually diminishing to low chc PoPs for showers into early Friday morning. Post- frontal CAA sets in, resulting in lows to drop to the upper 40s/lower 50s in the Piedmont under clear skies. It will remain much warmer closer to the coast due to clouds and mixing, with lows generally 60-65F.

After some lingering clouds/showers (mainly E) early on Fri, expect gradual clearing through the aftn as the frontal zone pushes farther offshore. For inland areas the entire day should be mainly sunny with dew pts in the upper 40s to lower 50s. Highs will be a little cooler than avg, generally in the mid 70s CWA-wide. Clear/cool Fri night as sfc high pressure settles over the local area. Went on cool side of guidance for most areas, lows in the upper 40s/lower 50s over the inland 2/3 of the CWA (mid 50s urban areas). Near the coast lows will be 55-60F. Mostly sunny and pleasant Sat with highs in the mid to upper 70s.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. As of 300 PM EDT Wednesday .

Generally quiet weather is expected through the long term forecast period. A weak surface trough is expected to cross the region Saturday night into Sunday morning bringing a reinforcing shot of drier and cooler air. Surface high pressure builds across the local area Sunday through Monday leading to continued dry conditions and mostly sunny skies. Highs on Sunday will range from the mid to upper 70s and overnight lows will dip into the low to mid 50s inland and upper 50s to low 60s closer to the coast. Temperatures moderate Monday and Tuesday as the flow turns southerly with highs in the upper 70s to lower 80s and lows in the mid to upper 50s. Another front approaches from the NW Tuesday afternoon and crosses the area Tuesday night, but precipitation chances still appears fairly limited with the front at this time. High pressure returns for Wednesday.

AVIATION /02Z THURSDAY THROUGH MONDAY/. As of 800 PM EDT Wednesday .

Low pressure is centered near Lake Erie as of 00z, with a cold front extending to the south across the central and southern Appalachians. The wind is SE 8-12kt locally ahead of the front, with VFR conditions at the TAF sites, but there are MVFR and localized IFR cigs over the Piedmont. Showers and a few embedded tstms from a few hours ago have dissipated, with only a few light showers lingering across the area. MVFR cigs are expected to reach RIC around and after 02-03z, with VFR conditions continuing at the remaining TAF sites overnight. A band of showers and embedded tstms are expected to accompany the cold front late tonight into Thursday. The cold front will be slow to cross the region with the highest rain chance at RIC late tonight into Thursday morning, PHF/ORF/ECG during the day Thursday, and SBY primarily Thursday afternoon. MVFR cigs are expected to develop at all sites Thursday, with occasional IFR/LIFR vsby possible in heavy rain. The wind is expected to gradually shift from SE to S tonight, S to SW Thursday morning into the afternoon, then shifting to WNW behind the front.

Some lingering low clouds and showers linger near the coast into early Friday morning. Otherwise drying out with VFR conditions are expected to return Friday through Monday as high pressure builds into the area.

MARINE. As of 400 PM EDT Wednesday .

Low pressure is deepening over ern Ohio this afternoon with a trailing cold front extending swd into the srn Appalachians. Meanwhile, high pressure has moved well off the New England coast. The pressure gradient between the approaching cold front and the area of high pressure is resulting in S to SE winds of 15-25 kt with gusts of 30 kt. Have even seen a few 35 kt gusts at elevated locations in the Ches Bay. Seas are 4-5 ft, with waves on the bay of 2-3 ft (perhaps closer to 4 ft right at the mouth of the bay). Winds are anticipated to remain S-SE 15-25 kt through much of Thursday morning. SCAs remain in effect for all marine zones (including the upper rivers) through Thursday aftn/evening. Seas are progged to increase to 5-7 ft by this evening-tonight, with waves in the bay generally in the 3-4 ft range through Thu AM. Cannot rule out 8 ft seas across the nrn coastal waters tonight-Thu. SCA conditions will prevail until the cold front crosses the waters Thursday afternoon. Prevailing gusts will generally be ~30 kt, although will likely continue to see brief gusts to ~35 kt at elevated sites. Showers/isolated tstms may also produce brief higher gusts from this evening-Thu, and a few SMWs may be required. Winds become W at 5-15 kt shortly after the FROPA. Seas will remain elevated through the day on Thursday (and into at least Thu night).

Wind speeds will remain 5-15 kt Thursday evening before increasing to 15-18 kt again with a secondary CAA surge late Thu night-Fri AM. Waves in the bay will diminish to 1-3 ft Friday evening. Seas are progged to drop to ~4 ft by Fri aftn. High pressure becomes centered southwest of the area Friday afternoon and through the weekend. Generally, winds will be N-NE at 10-15 kt Friday afternoon through Saturday AM. Winds become W-NW at ~10 kt through the remainder of the weekend. Seas/waves remain sub-SCA during the remainder of the weekend.

TIDES/COASTAL FLOODING. As of 400 PM EDT Wednesday .

Tidal anomalies have risen to 1-1.2 ft above normal in the upper bay/tidal Potomac due to increasing S-SE winds. With persistent 15- 25 kt S-SE winds, tidal anomalies will steadily rise (to around 1.5 ft above normal) in the mid/upper bay through at least tonight. This combined with high astronomical tides will very likely result in minor tidal flooding in some locations on the bay side of the MD Ern Shore (especially Cambridge and Bishop's Head in Dorchester County MD) and along the tidal Potomac. Have issued a Coastal Flood Advisory from this evening through tonight for Dorchester County as well as Northumberland/Westmoreland along the tidal Potomac. Will go with a Coastal Flood Statement for the Crisfield area, where water levels are forecast to crest around or just below minor flood thresholds. Tidal flooding could linger through high tide Thursday aftn/evening, especially if the FROPA is on the later side (and S-SE winds persist longer than expected). Guidance is starting to catch onto this, and will likely need another round of advisories on Thu for the upper bay if this trend persists. Water levels should start falling by late Thu night as northerly winds increase following the FROPA. Not expecting much in the way of tidal flooding issues in the Lower Bay (and on the Atlantic coast).

Lastly, have issued a Coastal Flood Advisory through 18z Thursday for areas on the north side of the Albemarle Sound (including the Back Bay area of VA Beach). Steady rises in water levels have been observed over the past several hours at gages in Edenton, Elizabeth City, and srn portions of the City of Virginia Beach. With decent S- SE winds expected to continue through tonight, it appears that minor tidal flooding is likely in these locations.

Will continue with a high rip risk through Thursday, although the greater threat will be large breaking waves as opposed to rip currents (but this warrants a Beach Hazards Statement nevertheless).
