Area Discussion for - Wakefield, VA
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 241840 afdakq area forecast discussion national weather service wakefield va 240 pm edt Sat aug 24 2019 Synopsis A cold front will stall along the carolina coast over the weekend. High pressure will build in from the north behind the front through today. Low pressure is expected to develop along the front early next week. Near term through tonight As of 1000 am edt Saturday... latest analysis indicating yesterday's sfc cold front well off to our s, with ~1029mb 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 day. Ample low mid level moisture is in place over the central and southern portions of the local area with radar depicting an area of light showers over south central va, slowly advancing eastward. Temperatures are significantly cooler than the past several days and range from the mid 60s in south central va to the upper 60s lower 70s across the remainder of the area. Have raised pops into the 30-40% chance range a little farther n to the southside of metro ric late this morning into the mid aftn period, before somewhat drier air advects in from the n. Maintained 30-60% pops across southern va and NE nc through the aftn, with highest pops expected after 18z focusing over far se va NE nc. Skies will be mainly cloudy for southern va and NE nc, with variably cloudy partly sunny skies across the northern 1 3 of the cwa. Highs will generally range from the mid to upper 70s, potentially cooler in areas where rain showers persist (only lower 70s for south central va and interior NE nc). 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 elsewhere. Lows range from the upper 50s NW to around 70f se. Short term Sunday through Monday As of 400 am edt Saturday... 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 could limit the day time heating. For now have gone close to 80f most areas, but if those lower clouds do hold together could see readings more in the mid 70s toward the southern va piedmont. The forecast for Sunday night into Monday could change rapidly over the next few days depending on the potential development of a tropical system of the SE us coast. The models are struggling with the development and location of the system with the 00z gfs quicker to develop the system and move it northward off the carolinas by Monday afternoon while the 00z ECMWF continues to be slower and farther to the SE off the coast with much less impact to the region. Very minor changes to pops with this update, maintained low chance pops with the moisture overrunning the wedging high. Again will need to monitor the potential tropical development along the SE us coast this weekend. Long term Monday night through Friday As of 300 pm edt Friday... 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 suggests that 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, 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. However, if the |
tropical system stays further offshore it is conceivable that much of the middle of next week will be dry other than perhaps some widely scattered afternoon evening storms. Otherwise, by Friday the GFS and ECMWF both show drying across the area as a ridge axis builds in from the west. As such, have kept Friday dry. Temps on Tuesday will trend slightly below normal due to the extensive cloudiness (although it will be muggy), but then rise to near normal for wed-fri. Aviation 19z Saturday through Thursday As of 200 pm edt Saturday... scattered light rain showers will continue across far southern va and NE nc into this evening. Still primarilyVFR conditions (though some MVFR CIGS may affect kecg this evening tonight). N to NE winds will range around 10 to 15 knots with gusts up to 20kt along the immediate coast and avg 5-10 kt farther inland. Partly to mostly sunny N and partly-mostly cloudy S for Sunday butVFR conditions are expected throughout. NE winds will again be somewhat elevated gusty along the coast at 10-15kt with gusts to 20 kt (with ~10kt inland). 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 630 am edt Saturday... a NE wind has increased to 15-20kt across the bay and mouth of the james early this morning. SCA flags have been added through 10 am as high-res guidance has the wind diminishing to 10-15kt later this morning into the aftn. Previous discussion... a cold front is pushing swd through nc early this morning as high pressure builds across the great lakes. The wind has shifted to nne behind the front 10-15kt, and this has resulted in 3-4ft seas in the ocean and 2-3ft waves in the bay. The high will build across upstate ny and into NRN new england today as the front settles off the carolina coast. Therefore, the wind will shift to NE and remain 10-15kt. The high strengthens and remains nearly stationary tonight. Meanwhile, an inverted trough begins to develop along the old frontal boundary and the pressure gradient will tighten along the mid-atlantic coast. A NE wind should increase to 15-25kt tonight into Sunday, with seas building to 4-5ft N and 5-6ft S later tonight into Sunday. SCA flags remain in effect for the bay and lower james, and have been added for the ocean (primarily for seas) and the currituck sound. The wind will remain NE Sunday night into Monday as tropical low pressure organizes off the carolina coast. Sca conditions for seas (potentially building to 5-8ft) will likely linger into early next week as the flow remains onshore and with low pressure over the ocean. By Tuesday night and Wednesday the wind should become N and then SW as the low pulls well offshore. This should allow seas to subside. Akq watches warnings advisories Md... None. Nc... None. Va...
