A cold front will continue to push into central Virginia this morning, and will be very slow to push through southeast Virginia and northeast North Carolina late this afternoon into this evening. Widespread showers and thunderstorms are expected today, lingering through the evening across southeast zones. Mainly dry conditions are expected late in the week into next weekend as high pressure brings lower humidity to the region. && .NEAR TERM /THROUGH TONIGHT/...-- Changed Discussion --As of 1000 AM EDT Wednesday... - A Flood Watch has been issued to focus on urban portions of SE VA where the Flash Flood Risk will be greatest today. - Localized flooding from heavy rainfall will be possible over the remainder of the area through most of the afternoon (or into the evening in NC) as well. Late morning WX analysis indicates a mid-upper level trough was slowly advancing eastward from the OH/TN Valley, and pushing to the Appalachians. At the surface, a cold front extends from eastern Canada through New England, and SSW into central portions of the FA. The local area remains in a moisture-rich airmass with latest PW values analyzed at or above 2.00" across most of the CWA, with slightly lower amounts to the SE. Slow- moving showers, with a few embedded lighting strikes, are producing very efficient rainfall rates across portions of srn VA, the Northern Neck, and MD Eastern Shore. Temperatures are generally in the low-mid 70s across the northern half of the area where cloud cover is thick and overcast, with upper 70s to lower 80s across the SE where breaks in the cloud deck are more prevalent. With the approaching upper trough axis, PWAT values > 2.00", and the slow-moving nature of the front, there appears to be ample support for heavy rain across the SE half of the area later today, especially during the afternoon and early evening hrs. The latest 02/00z HREF has a nearly similar footprint of 30- 50% neighborhood probs for 3"/3 hr, focused across far SE VA and NE NC. WPC has maintained the Slight ERO across SE VA and NE NC. Given this, decided to raise a Flood Watch for the more urbanized zones in SE VA where the flash flood risk will be highest (due much lower FFG values). The flow aloft and the low level jet are nearly identical today, SW at 15-25kt, suggesting some potential for backbuilding storms. In addition, there will likely be some modest heating with lower morning PoPs, from southside Hampton Roads into NE NC. This could allow for some localized strong wind gusts given moisture laden updrafts in a high PW airmass. While SPC did not outlook the area, mainly due to relatively weak lapse rates and uncertainty in the duration of morning heating, there still could be an isolated strong storm or two this afternoon. The latest HRRR shows some modest low- level shear and hodograph curvature across SE VA/NE NC in the afternoon/early evening (0-1 km SRH around 50 m2/s2). Combined with the lower LCLs from the moisture- rich environment and elevated 0-3km MLCAPE, a non- zero tornado threat could materialize, but will note that confidence in this scenario is low. High temperatures will mostly be in the low-mid 80s today (some areas could potentially not get out of the upper 70s) with PoPs ranging from 40-60% N to 70-90% SE with the front lingering over the local area. Overall, NW zones will tend to see diminishing PoPs by late aftn as drier air moves in, and would rise into the 80s late in the day, while far SE zones could briefly surge well into the 80s this morning then fall into the 70s with the widespread aftn convection. The models are in decent agreement that the front pushes SE of the region tonight, allowing for diminishing PoPs through the evening and mainly dry conditions after midnight except perhaps right along the coast in the SE through ~06Z. Lows tonight will range from the mid- upper 60s W/NW to the lower 70s SE. Patchy fog is possible after midnight, mainly along and W of I-95.-- End Changed Discussion --&& .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... As of 400 AM EDT Wednesday... Key Messages: - Turning drier behind the front Thursday. - Dry and noticeably less humid for the Fourth of July holiday. A lingering shower or storm or two is possible across NE NC Thursday afternoon near the decaying boundary. A secondary cold front also approaches from the N Thursday. However, PoPs are generally < 15% in other locations given a drier airmass. High temperatures return to the upper 80s to lower 90s, with heat indices mainly in the mid 90s as dewpoints drop into the upper 60s to lower 70s Thursday. Mostly clear with lows Thursday night dropping into the mid to upper 60s well inland to the low 70s near the coast. A pleasant and dry, but still warm, Fourth of July holiday looks to be in store as an upper trough axis slides through and high pressure builds to our N. Highs temperatures range from the mid/upper 80s to around 90 F, with sunny to mostly sunny skies and light onshore flow. Dew points range through the 60s (potentially down into the upper 50s at peak heating across the northern 1/2 of the CWA), so it should feel quite comfortable. Mainly clear friday night with lows mostly ranging through the 60s (lower 70s SE coast). && .LONG TERM /SATURDAY THROUGH TUESDAY/... As of 420 AM EDT Wednesday... Key Messages: - Mainly dry through the upcoming weekend, with lower dew pts keeping conditions relatively comfortable. - Becoming increasingly humid by next week with highs in the 90s. Upper level ridging will start to build from the mid MS Valley east into the local area over the weekend, as a weak upper level trough organizes over the eastern Gulf and Florida. Highs trend back toward the 90s, but dewpoints will be slower to recover Saturday and mainly dry conditions are expected for the Independence Day holiday weekend. A gradual increase in humidity starts Sunday, and especially Monday-Tuesday along with chances of diurnal showers/tstms well in advance of another cold front moving into the Great Lakes. The other uncertainty is with respect to the upper low across the Gulf and SE CONUS. The latest GFS/ECMWF bring a bit of the upper trough axis north to the coastal Carolinas as early as Sunday and linger it there early next week. Have added a slight chc for aftn showers/tstms on Sunday into the forecast for NE NC. The latest NHC forecast has increased the probability for a tropical or subtropical system to 40%, though other than increasing rain chances next week, any impacts would remain well S of the local area. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/...-- Changed Discussion --As of 200 PM EDT Wednesday... Degraded flying weather continues this afternoon with conditions highly variable over time as bouts of rain and lower CIGs move through ahead of a weak cold front. Highly efficient rain- producing showers have lowered VSBY extensively when they pass over a terminal. Will handle lingering/brief IFR CIGs at SBY and RIC with TEMPO groups. Some potential for fog later tonight here as well. Latest guidance has trended toward fewer thunderstorms at ORF/PHF this afternoon. Not so for ECG where deeper instability lingers into the late afternoon or early evening. MVFR CIGs are likely at PHF and ORF tonight with IFR hanging on near ECG toward sunrise. Winds are generally light and variable and should remain that way through much of the TAF period, becoming WNW 5-10 kt by mid morning Thursday. Outlook: VFR conditions return Thursday through Sunday as drier air builds into the region behind the cold front.-- End Changed Discussion --&& .MARINE... As of 330 AM EDT Wednesday... Key Messages: - SCAs remain in effect through the early morning hours. - Benign marine conditions are expected to return by this afternoon and last through the extended period. Early morning analysis shows a 1020mb high pressure over Bermuda and a stalled out cold front over western Virginia. Ahead of the cold front winds continue to remain out of the SW. Winds remain between 10 to 15 kt across the bay and water with some gusts upwards of 20 kt. In addition to the SW winds this morning, some showers and thunderstorms continue to make their way across the waters. These Showers and thunderstorms continue to weaken as instability is depleted across the area. Waves this morning are between 2 to 3 ft across the bay and 4 to 5 ft across the ocean. With the winds still gusting to 20 kt across the bay and 5ft seas across the ocean SCA will continue to remain in effect through the early morning hours today. If real time observations continue to show a decrease in winds and waves there is potential that the SCA maybe canceled earlier. By this afternoon, the cold front will again to propagate eastward across the waters bringing a chance of showers and thunderstorms. These thunderstorms could potentially bring gusty winds and elevated seas. The stronger storms will be handled with SMW. Winds this afternoon will shift from the SW to WNW between 5 to 10 kt with gusts upwards of 15 kt. Waves will also decrease through the afternoon with 1 to 2 ft seas in the bay and 2 to 3 ft seas in the ocean. By late this evening and into tonight high pressure will build back over the area bringing benign marine conditions to the local waters. These conditions as of now are expected to last through the extended period. && .CLIMATE...
