Fxus61 kakq 251600 afdakq area forecast discussion national weather service wakefield va 1200 pm edt Sun aug 25 2019 Synopsis A cold front will remain stalled well to our south through tonight. High pressure will become centered over new england early Monday through Tuesday as low pressure is slow to lift northeast well off the carolina coast. Near term until 6 pm this evening As of 12 noon edt Sunday... no major changes to the going forecast required, with only minor edits per latest obs. Slow clearing across south central va over to the middle peninsula late this morning will continue, with bkn-ovc clouds ~4 kft agl persisting across far SE va NE nc. Partly to mostly sunny inland... Mostly cloudy SE coast. Mainly dry, but some sct shras drizzle possible along the immediate coast this aftn. Highs mainly in the 70s to near 80 well inland. Previous discussion... as of 350 am edt Sunday... as of this morning, surface high pressure at around 1030mb is located north of the region, centered over new england. Meanwhile, a cold front is well south of the region, draped across southern sc ga and extending out along the carolina coast. A shortwave aloft has allowed for some lower clouds and light showers drizzle to overspread southern portions of the region (mainly NE nc and far se va) where low level moisture remains the highest. Fully expect the precipitation to slowly diminish through the morning hours as drier air continues to work in from the north. High res model guidance continues to indicate the possibility for a few widely scattered showers this afternoon due to strong easterly flow departing shortwave. Any shower activity should generally be confined to areas east of interstate 95 and pops are only in the slight chance category. High temperatures will range from the upper 70s to around 80 under partly to mostly sunny skies to the north with partly to mostly cloudy skies south and east. Short term 6 pm this evening through Tuesday As of 350 am edt Sunday... the forecast for Sunday night through Tuesday 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, continued to generally disregard the NAM as it struggles greatly with anything tropical. Continued to follow 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 chance 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 16z Sunday through Thursday As of 700 am edt Sunday... generallyVFR conditions expected at all TAF sites through tonight. High pressure to the north will let clouds scatter out somewhat through this morning and afternoon, especially to the north and west. Low level moisture lingers closer to the coast thus skies will remain sct- bkn across the south east. In addition, a very scattered rain shower cannot be ruled at eastern TAF sites this afternoon and evening. Gusty northeast wind of 15 to 20 knots at orf ecg, around 10 knots elsewhere. Lower clouds may try to develop by early Monday, potentially creating sub-vfr conditions at all TAF periods for a period of time. 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 350 am edt Sunday... 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...

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
