AREA FORECAST DISCUSSION National Weather Service Wakefield VA 442 AM EDT Thu Jul 9 2020
SYNOPSIS. Low pressure moves slowly northeast along the North Carolina coast today and tonight before lifting northeast along the Mid Atlantic coast Friday and Saturday. A frontal boundary will linger along the coast through the weekend.
NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 400 AM EDT Thursday .
SPS thru 12Z for ptchy dense fog across the lwr Md ern shore.
Latest MSAS shows weak high pressue over the Va Piedmont with low pressure just east of ILM. The system seems to be meandering and getting better organized as the sat loop is showing cooling cloud tops out over the Gulf Stream east of MHX. NHC conts to monitor for potential tropical development over the next 24 hrs.
Models and current data suggests this systms track is more over the water than land (along the Gulf Stream) thru 21Z, then slowly turning it nnw and moving it towards HAT by 00Z. This slower track will result in some significant changes to the grids today. Main change was to lower PoPs across the board this morning, then bring likely PoPs into sern VA/nern NC this aftrn. Chc PoPs elsewhere with only a 20-30 PoP along and west of I95 and lwr Md ern shore as the weak high slowly gives way to the storms moisture fields. Thunder was cut back as well, basically limited to the aftrn given modest instability in the tropical airmass. Depending on radar trends this morning, will have to monitor for possible waterspouts in the outer most bands of the systm as they apprch the nrn OB/sern Va.
QPF was also cut back thru 00z, with amts btwn 1/2 to 3/4 inch limited to far sern VA/nern NC zones. A flash flood watch was considered starting today, but given the uncertainity and changing trends, decided to hold off on any watch and let the day shift evaluate the need for one later today.
Otw, Pt sunny skies become mstly cldy. Highs low-mid 80s east, btwn 85-90 west where there will be more sun and less pcpn.
SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/. As of 400 AM EDT Thursday .
Models in decent agreement tracking the systm near or along the nrn OB this eve, just east of Va Beach late tonite then hugging the Delmarva coastline Fri morning before pushing north into NJ Fri aftrn. Data also suggests the greatest wind affects will be over the waters, but moisture fields (highest PW's) show a signifcant surge of tropical moisture accompanying the systm as it tracks north tonite and Fri. There will also be a sharp pcpn gradient west of the Ches Bay. Thus, PoPs will be highest tonite and Fri along the coast with chc PoPs to the west. QPF is anthr challenge and will likely determine where a ff watch will be needed. Best guess attm will be along the ern shore where a general 2-3 inch rainfall is expected with amts up to 4 inches from SBY-OXB. 1 to 1.5 inches over the Ches Bay and sern Va/nern NC with much less amts to the west. Lows tonite upr 60s-lwr 70s. Skies will likely become pt sunny Fri as the systm moves ne pulling in drier air on gusty NW winds. Highs mid 80s along the ern shore, upr 80s-lwr 90s west of the Ches Bay.
The system continues to track NE of the local area Fri night and Sat. However, lingering moisture along a lagging trof keeps the chc for sct convection going. Lows Fri nite in the low-mid 70s. Highs Sat in the upr 80s-lwr 90s. HI values Sat in the upr 90s-lwr 100s.
LONG TERM /SUNDAY THROUGH WEDNESDAY/. As of 315 PM EDT Wednesday .
Overall the operational models are in decent agreement with a Eastern US Trough being the dominant weather feature in the extended period, but the strength of the trough differs. The GFS is sharpest and deepest during the period while the ECMWF is quicker to begin lifting the trough out toward the end of the period. For now have blended between the two with having more convective activity early in the period on Sunday and Monday with a stronger trough and an associated sfc cold front moving into the area. Then begin to lessen the chances for convection by mid week as the surface front dissipates and the Bermuda High starts to rebuild into the SE US. The pops are mainly diurnal with the best chances for pcpn late in the afternoon into the early evening. For temperatures have kept readings in the low 90s through the period, but should the trough deepen a little more on Sunday into Monday, would not be surprised to see temperatures held down just a touch into the upper 80s for early in the week. But overall should not be far from normal with highs in the lower 90s and lows in the low to mid 70s.
AVIATION /09Z THURSDAY THROUGH MONDAY/. As of 130 AM EDT Thursday .
Weak high pressure over the area erly this morning with low pressure dvlpng just ene of ILM. Sct SC btwn 1-2K FT along with ptchy fog dvlpng in some places and will cont to do so thru the pre-dawn hrs. Shwrs from the coastal low will overspread the sern TAF sites by or shortly aftr 12Z them spread n along the coast thru out the day and tonite. Lclly hvy downpours will result in MVFR CIGS with pockets of IFR VSBYS at times along the coast. RIC sees little rain chcs. Gusty ene winds btwn 15-25 kts along the coast late today and tonite.
OUTLOOK . Degraded flight conditions will continue through Friday along the coastal TAF sites as the low moves up the Mid Atlantic coast. Conditions generally improve on Saturday, although afternoon/evening showers and storms may result in brief flight restrictions.
MARINE. As of 430 AM EDT Thursday .
An are of low pressure has emerged off the NC overnight, south of Cape Hatteras, and is becoming better organized. The NHC has given a 80% chance developing into a tropical depression today as the low tracks north towards our area. SCAs have been issues for most of the area coastal waters through Friday afternoon as the low tracks along the Carolina and Mid-Atlantic coasts.
Conditions this morning are fairly benign, especially north of the VA/NC border. Winds are E 5-10 kt with the low pressure centered well south of the area. Winds will quickly increase throughout the morning for the southern portion of the area. Easterly winds are expected to be around 20 kt, with gusts near 25 kt by mid morning today for areas south of Cape Charles and the southern portion of the Chesapeake Bay and lower James River. The center of low pressure will be north of Cape Hatteras by this evening and winds will be increase across area waters. Winds are expected to be NE 20-25 kt. with gusts up to 30 kt for the southern Chesapeake Bay and VA/NC Atlantic coastal waters by this evening. Seas will be increasing to 5- 7 ft, and waves in the Chesapeake Bay and James River will be 2-4 ft (4-5 ft near the CBBT).
The center of the low pressure will be track north along the VA coast tonight. At this time, the track of the low appears to remain just off our coast. Therefore, winds will become NE then N 15-20 with gusts up to 30 kt as the low passes just to the east. This may change with any shift in the track.
Winds will become W to NW as the low pressure tracks north towards the NJ coast Friday. Winds will be decreasing from south to north during the day on Friday with SCA condition continuing into Friday afternoon.
For the weekend, winds will be SW 10-15 with gusts up to 20 kt and the chance for afternoon thunderstorms.
TIDES/COASTAL FLOODING. Nuisance to minor coastal flooding is possible around high tide cycles on Thursday and Friday. Water level rises of around 1 ft above normal tide possible.
High risk of rip currents on Thursday for Virginia Beach and NE NC beaches. Moderate risk of rip currents for the MD/VA eastern shore.
