(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 231107 afdakq area forecast discussion national weather service wakefield va 707 am edt Fri aug 23 2019 Synopsis A cold front will slowly cross the mid-atlantic region today into tonight. The front is expected to stall along the carolina coast Saturday and Sunday as high pressure builds north of the area. Low pressure is expected to develop along the boundary Sunday night into Monday. Near term through tonight As of 400 am edt Friday... current WV imagery places a trough from the great lakes to ern canada, with a broad ridge from the southeast CONUS into the sub-tropical WRN atlantic. At the surface, a cold front is located in vicinity of the ohio valley, with high pressure located well off the southeast coast. Partly to mostly cloudy, warm, and humid early this morning with temperatures of 70-75f and dewpoints in the upper 60s to low 70s. The trough over the great lakes will continue to dig swd today pushing the cold front into the mid-atlantic by this aftn. On average, numerical models forecast 1000-1500 j kg of mlcape across central portions of the area, with 1500-2500 j kg across srn SE portions. This combined with 25-35kt of 0-6km bulk shear should allow tstms to organize into some discrete cells and line segments, with the primary threat being damaging wind gusts this aftn. After this initial severe threat, the main hazard will be heavy rainfall. Pw values are expected to reach 2.0-2.25", with a slow moving front and a deep warm cloud layer. 23 00z href has a rather strong signal for some excessive rainfall across central SRN va and NE nc late this aftn into this evening. The threat is not widespread enough to warrant a flash flood watch, plus much of this area is ~10-25% or 25- 50% of normal for rainfall the past 14 days. Not as hot but still humid today with high temperatures ranging from the upper 70s to ~80f n, to the mid upper 80s S and se, with dewpoints still in the 70s. The cold front gradually drops through the area later tonight with pops diminishing from NW to se. Low temperatures range from the low mid 60s n, to the low 70s se. Short term Saturday through Sunday As of 400 am edt Friday... the front is expected to settle near the carolina coast by Saturday as high pressure builds N of the region. Low-level moisture will be slow to clear over NE nc where pops remain 40-60%. Additionally clouds will likely be slow to clear across the N with NE flow off a relatively warm ocean. Highs Saturday will generally be in the upper 70s to around 80f and could be a few degrees cooler if rain lingers longer. By Saturday night and Sunday the high will continue to build to the n. However, models suggest an inverted through could sharpen along the frontal boundary (nam is most aggressive). If this were to occur there is the potential for anomalous easterly flow with the high to the N and this could spread some bands of heavier rain into ERN nc, some of which could inch N of the albemarle sound. Lows Saturday night range from the upper 50s to low 60s n, to the low 70s se. Highs Sunday are forecast to be in the upper 70s to around 80f. Long term Sunday night through Thursday As of 4 pm edt Wednesday... the extended period (Monday) will start with below normal temps as high pressure remains centered over the canadian maritimes with low pressure off the nc outer banks. There is a chc of a few showers tstms (mainly across southern eastern portions of the cwa) on mon. Highs mainly in the low 80s on mon. Expect slowly warming temperatures throughout next week as the aforementioned area of high |
pressure retreats offshore and the low off the outer banks moves to our northeast. Mainly dry on Tue (although an isolated aftn-evening tstm cannot be ruled out over the area... Mainly south west). There is a better chc for aftn-evening showers tstms on Wed as strong low pressure (sfc-aloft) tracks over ontario and the trailing cold front slowly approaches the region from the nw. Have pops of 30-35% W 20% e Wed aftn-wed evening. The frontal boundary potentially lingers over the area on thu, so kept slight chc low-end chc pops in the grids (highest during the aftn-evening). Highs in the mid 80s on Tue warming into the upper 80s by wed-thu. Low Mon night mainly in the 60s. Slightly warmer Tue night-thu night with lows in the upper 60s NW low 70s se. Aviation 11z Friday through Tuesday As of 200 am edt Friday... a cold front is pushing into the mountains as of 11z, with high pressure centered well off the southeast coast.VFR conditions prevail under sct high clouds, with a 5-10kt SW wind. The cold front will advance to the southeast today, with the leading edge reaching ric and sby by 16-19z, phf orf 21-00z, and ecg 00-03z. Low pressure will track along the boundary and showers tstms are expected to become widespread, primarily after 19z. MVFR ifr vsby is expected in heavy rain, with MVFR and potentially ifr CIGS developing by this evening in NE flow behind the front. A few strong wind gusts are also possible with the initial tstms this aftn. Degraded flight conditions are expected to continue later tonight with a 20-30% chc of showers from ric-sby, and 30-60% over SE va NE nc with some embedded tstms over NE nc. The cold front settles along the carolina coast Saturday into Sunday. Low pressure is expected to develop along the front by Sunday night, before lifting to the NE Monday into Tuesday. A chc of showers will continue, with the highest probability over se va NE nc. Marine As of 330 am edt Friday... a cold front located just north of the local waters will slowly drop south through today before slowing down further nearly stalling near the va nc this evening. The front finally settles south of the region by Saturday. Ahead of the front, SW will range around 10 to 15 knots. Behind the front, winds shift to the N and eventually NE at around 10 to 15 knots. Seas today and tonight will generally range from 2 to 3 feet, and waves in the bay around 1 to 2 feet. As surface high pressure builds in from the north and low pressure develops along the southeast coast on Saturday, ne winds will likely increase to 15 to 20 knots with gusts to 25 knots. Small craft advisories will likely be needed late Saturday through Tuesday as onshore flow persists. NE flow will allow for seas to build to 5 to 6 feet (potentially 7 feet out 20 nm) and waves at the mouth of the bay to build to as high as 4 to 5 feet. Winds and seas look to diminish by mid-week.
