(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 240103 afdakq area forecast discussion national weather service wakefield va 903 pm edt Fri aug 23 2019 Synopsis A cold front will stall along the carolina coast over the weekend. High pressure will build in behind the front Saturday. Low pressure is expected to develop along the front early next week. Near term through Saturday night As of 900 pm edt Friday... cold front assctd pcpn now sagging into nc. Still some lingering moisture north of it into SRN va. Threat of svr storms is over so cancelled the rest of the watch. Although some lclly hvy downpours cont across nern nc, the the rainfall intensities have lightened up and flash is not that excited about flooding, so went ahead and cancelled the flash flood watch with this update. Some minor flooding is still psble over the next few hrs, but nothing significant expected. Latest high res data suggests shwrs linger along the border thru the nite then actually drift north across SRN va Sat morning. Thus, mstly cldy to cldy skies overnite with chc pops except likely across nc. Lows lwr 60s NW to lwr 70s se. Pvs dscn: by Saturday morning the front is expected to be just off the carolina coast. High pressure builds in behind the front. NE flow and plenty of low level moisture will be available that additional showers will be around, especially in far SE va and NE nc where pops will still run 50-70 percent. High temps on Saturday will be much cooler, only reaching the upper 70s in most locations, possibly cooler in areas where rain persists. There will be a noticeable drop in humidity especially from i64 north where dewpoints will be in the upper 50s to lower 60s. Winds behind the front will be out of the n NE generally 5 to 10 mph, and a bit higher right along the coast. Short term Sunday through Monday As of 320 pm edt Friday... the models continue to push the sfc cold front southward toward the carolina coast by Saturday evening and then stall it along the coast as the surface high builds eastward into new england with a good set up for a wedge to develop along the eastern seaboard. The big adjustment was to continue to slow the progression of the pops southward on Sat night as another shortwave rotates through the exiting trough over northeast and mid-atlantic. 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 the va tidewater 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 80s 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 12z gfs quicker to develop the system and move it northward into the carolinas by Monday afternoon while the 12 ECMWF is slower and farther to the SE off the coast with much less impact to the region. So for now have maintained a low chance pops for showers with the moisture overrunning the wedging high and getting temperatures back toward the lower 80s with good onshore flow. 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 01z Saturday through Wednesday As of 745 pm edt Friday... cold front and assctd convection now along the va nc border and is slowly sagging to the se. Convection has ended at ric sby and phf. Based on latest radar obs, kept vcts at orf and will keep a tempo group at ecg for a few more hrs. Wind shift to the n-ne has brought a bkn ifr st deck in north of the front. Models show the ifr CIGS lingering for a few hrs then remaining lifting a bit to btw 1-2k ft overnight. Cigs will be slow to rise Sat but should eventually goVFR by 18z. N-ne winds 10-15 kts along the coast, less than 10 kts away from the water. Outlook... low pressure developing along the stalled front and a high building in to the north will keep an easterly flow with ample moisture for the chance of additional showers especially at eastern TAF locations into erly next week. Marine As of 245 pm edt Friday... sfc cold front continues to drop south across waters this aftn. Latest observations reflect nnely flow over northern waters just north of the front, with ssw flow over southern waters 10-15 kt just ahead of the boundary. Sfc cold front will continue to slowly drop south through central and southern waters late today through this evening, before slowing down further nearly stalling near the va nc this evening... Eventually pushing south of the region by Saturday aftn. Ahead of the front, SW will continue ~10 to 15 knots. Behind the front, winds veer around to the nne at around 10 to 15 knots. Still expect a round of showers and t-storms, with numerous smw mws likely with convection along the frontal passage this evening over the bay, rivers and northern central waters. A short-lived surge likely as cooler air initially settles across the waters. Seas this aftn 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 have been issued for Saturday night and Sunday over the bay and lower james, and may be needed with into early next week 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. High pressure will continue to nose in from the north as the cold front becomes quasi-stationary offshore late Sat through Sunday aftn. By Sunday night, sfc low pressure begins to take shape and eventually slides NE along the front offshore into early next week. Pressure gradient becomes more compressed with time Mon tue. While considerable model differences persist, probabilistic models all seem to show sfc low tracking along the front. The GFS is a bit weaker slower and closest to the coast, while the ECMWF and its ensemble mean stronger and farther offshore. Upshot for the moment is strongest winds will remain offshore and will reflect as much for now. Nnw wind orientation should keep seas on the lower side of the envelope and will stay just below wavewatch. Akq watches warnings advisories Md... None. Nc... None. Va... None. Marine...
