(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 201933 afdakq area forecast discussion national weather service wakefield va 233 pm est Tue nov 20 2018 Synopsis Weak high pressure builds across the area from the west tonight into Wednesday, before another strong cold front passes through the area later Wednesday night. Canadian high pressure builds across the area for thanksgiving day into Friday. A low pressure system then impacts the region Saturday. Near term through tonight As of 230 pm est Tuesday... latest surface analysis shows that the cold front is currently across the SE part of the forecast area. Radar imagery indicates a few sprinkles across the middle peninsula and moving into the chesapeake bay. These should quickly move offshore by late this afternoon as the front moves offshore. Otherwise, expect the clouds to clear out this evening as downslope flow continues. Cold dry advection across the area as the high builds in will allow temps to drop into the lower 30s west of i-95 and the md eastern shore, and mid-upper 40s se. Short term Wednesday through Friday As of 230 pm est Tuesday... quiet day on Wednesday with the high pressure in control. Actually see some weak warm advection aloft ahead of the clipper system currently over the northern plains. However, with the weak wedge in place am still expecting temps to only be in the low to mid 50s. The cold front associated with the clipper system and leading edge of canadian air will pass across the area Wed night. Still looking at a very cold thanksgiving and thanksgiving night with highs on Thursday only in the mid 30s north to lower 40s south, which is below mos guidance. No record temperatures are expected, but temperatures are forecast to be up to 25 degrees below normal for this time of year. Friday morning temps will be in the around 20 NW to upper 20s SE as the high pres ridge is centered over the area. Certainly could not rule out mid- upper teens NW of ric with the expected very dry airmass. Even the beaches will likely see temps at freezing by Friday morning. Slightly warmer on Friday, under another day of sunshine, but still temps only in the 40s with the cold ridge still in place across the region. Long term Friday night through Tuesday As of 230 pm est Tuesday... no major changes to the extended forecast. Models still in good agreement in widespread rain moving into the area ahead of the system moving out of the SE states Saturday. Will continue with a mixture of rain possible sleet far NW late Friday night as the column may be cold enough initially for a brief period of frozen precip at the onset well NW of ric. Otherwise, just moderate rain on the day Saturday with up to an inch of rain possible. Doubtful this could cause any new flooding issues though. The area quickly dries out Saturday night then remains dry through Sunday night before a complex low pres system over the great lakes impacts the region for sun night into Monday bringing another chance for rain. We will be on the warmer side of this system, but thunder is not forecast right now due to the strong wedge remaining in place at least at the onset. Temps through the weekend into early next week will be warmer than thu Friday, and closer to normal especially by Sunday Monday with highs in the upper 50s lower 60s and upper 30s to 40s. Aviation 18z Tuesday through Sunday As of 130 pm est Tuesday... vfr conditions expected for the next 24 hours. Will see some cumulus this afternoon at around 4000 ft, but these should quickly dissipate after sunset. Gusty NW winds this afternoon |
may gust to 20 to 25kt especially at ric and sby. Outlook...VFR conditions expected through Fri with high pressure in control. Next system may bring ifr conditions to all sites on Saturday. Marine As of 400 am est Tuesday... w SW winds of 10-15 kt prevail early this morning out ahead of a cold front approaching from the west. The front will move through the area early this aftn, shifting winds to the nw. Cold advection and pressure rises in the wake of the front are not overly impressive, but should see winds increase to 15-20 kt over northern sections later this aftn and probably another few kt by early evening. Will continue with SCA headlines for the bay north of new pt comfort and also added the coastal waters north of parramore island for expected gusts to ~25 kt and seas building to around 5 ft at the outer edges of the 20 nm zone by this evening. The winds and waves seas should subside diminish below sca thresholds by early Wed morning as weak high pressure briefly builds over the waters. A strong cold front is expected to cross the area wed night, with strong sfc high pressure building south into the region for thanksgiving day. The pressure gradient is not excessive, but cold advection is impressive for this time of year with deep mixing over the relatively warm waters likely. Thus, went a few kt stronger than guidance and anticipate strong SCA conditions for much of the area (probably enough that all zones may need headlines). Seas build to 5-7 ft and bay waves to ~ 4 ft. Conditions briefly improve for fri, then winds ramp up again with the next system sat. Hydrology As of 400 am est Tuesday... a river flood warning remains in effect for sebrell on the nottoway, and an areal flood warning is in effect for the mattaponi at beulahville.

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. |
