(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 242336 afdakq area forecast discussion national weather service wakefield va 736 pm edt Sat aug 24 2019 Synopsis A cold front will remain stalled well to our south through the weekend. High pressure will become centered over new england Sunday night through Tuesday as low pressure is slow to lift northeast well off the carolina coast. Near term through Sunday As of 355 pm edt Saturday... latest analysis indicating yesterday's sfc cold front well off to our s, with ~1028mb sfc high pressure centered over the northern great lakes. Aloft, a trough is situated over eastern ny pa and is progged by the models to slowly sag SE through the evening. Ample low mid level moisture is in place over the southern portion of the local area with radar depicting an area of light showers over far southern va and NE nc, slowly advancing eastward. Temperatures are significantly cooler than the past several days and range from around 70f in south central va to the mid upper 70s across the remainder of the area. Shortwave aloft rotates SE through the region tonight, but deep layered moisture becomes confined to far SE sections so will focus chance to low-end likely pops there (at least through 06z), with mainly dry conditions and clearing skies elsewhere. Lows range from the mid to upper 50s NW to around 70f se. By Sunday morning, the surface high looks like it will push the moisture far enough south to limit the chances for any showers to mainly NE nc and far SE va with drying of the mid and upper level expected to continue through the day on Sunday suppressing the pcpn farther south through the day. However, the low level moisture should remain in place with strong easterly flow through about 850 mb. That may be enough to hold clouds in place and bring a few isolated showers to mainly areas along E of i-95. Have a 20% pop in these areas by aftn. Highs will avg in the upper 70s to around 80f under partly to mostly sunny skies n, with partly to mostly cloudy skies s. Short term Sunday night through Tuesday As of 355 pm edt Saturday... the forecast for Sunday night through Tue will be largely dependent on the development evolution of a potential tropical low pressure system moving slowly NE (but remaining offshore of) the SE us coast. Given that this is likely to be tropical, will be disregarding the NAM as it generally struggles greatly with anything tropical. Following a gfs ECMWF wpc blend (with fairly decent agreement) centers the sfc low NE off the ga north fl coast Sun night, and lifts it slowly NE well off the carolina coast mon-tue. High pressure generally remains in place over new england and atlantic canada through the period. This keep a persistent E to NE low level onshore flow into the local area. Deeper moisture looks to stay offshore, but will see a gradual increase in dew pts and precipitable water values through the period. Have maintained mostly 20-30% pops for both Mon tue, primarily due to the moisture overrunning the wedging high rather than the sfc low itself (as it will be well offshore). Again will need to monitor the potential tropical development evolution early next week as a shift closer to the coast would increase impacts (mainly from higher pops heavier rain potential). Highs will be mainly in the upper 70s lower 80s mon, and 80-85f tue, with lows in the 60s Sun night Mon am and mid 60s to lower 70s Mon night Tue am. Skies will be partly to mostly cloudy. Long term Tuesday night through Saturday As of 355 pm edt Saturday... the early part of the extended forecast will depend much upon any |
development and potential track of the tropical disturbance currently off the fl coast. Latest NHC outlook keeps this system will stay well off the local coast. Despite that, given the proximity to the tropical system and the potential for some tropical type showers to move across the area with a persistent ne-ene flow, and some reinforcing moisture lift from weak upper disturbances moving across the mid atlc and NE states in the w-sw flow aloft, will maintain low chance pops Mon night through thu. An upper-level trough will move into the great lakes for the end of next week and the weekend. A cold front will approach the area from the west. Ahead of the front, conditions should remain mostly dry with temperature approaching 90 inland and mid 80s along the coast for the first half of the holiday weekend. Aviation 00z Sunday through Thursday As of 730 pm edt Saturday... the cold front has settled across the sern states with high pressure well to the north of the local area this eve. Weak energy moving ene in the flow is resulting in sct light rain shwrs across nc and southside va. Based off the latest high res data, kept vcsh at ecg thru 12z as the moisture lingers there. Otw, generally aVFR cig btwn 5-8k ft across the TAF sites tonight. High pressure to the north will tend to sct out the cu Sunday at ric sby phf while sern TAF sites remain sct-bkn cu. Gusty NE wind (15-20kts) at orf ecg, AOB 10 kts elsewhere. Outlook: low pressure developing along a stalled front and high pressure centered to our N NE will keep an easterly flow across the region mon-tue, allowing for ample moisture, a chance for showers, and the potential for sub-vfr ceilings from time to time (especially at eastern TAF locations) mon-tue. Marine As of 415 pm edt Saturday... late this aftn, sfc high pressure was centered over the ern great lakes, with a frontal boundary now well to the south. Ne winds were mainly 10-20 kt over the waters, with waves 1-3 ft and seas 3-5 ft. The high will build eastward to over NRN new england tonight thru mon, as weak low pressure will lift NE off the SE coast. This will result in persistent NE winds of 10-20 kt with gusts to 25 kt possible thru the period. Waves will build to 3-4 ft in the ches bay, and seas will build to 5-8 ft over the ocean. So, at this time, have sca's for all the waters except zns 635 636 637 thru the short term period. Sca conditions for seas will likely linger into Wed morning, as the flow remains onshore due to low pressure out over the ocean. Equipment Kdox has returned to normal ops.
