(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 221130 afdakq area forecast discussion national weather service wakefield va 630 am est Fri feb 22 2019 Synopsis A frontal boundary stalls over the mid atlantic and southeast states into Saturday, as high pressure builds eastward from the great lakes into new england. The front will lift back north as a warm front Saturday. A cold front will then cross the region Sunday. Near term through tonight As of 340 am est Friday... unsettled weather pattern will continue today with plentiful moisture streaming into the area from the south and west. This moisture will interact with a stalled frontal boundary to warrant decent rain chances across the region, with the highest pops focused across the southern half of the area today. QPF will range from a few hundredths across the north to 0.25-0.50" across the south. Widespread clouds and the front to our south will lead to a cool day with mid 40s expected for high temperatures. Highest pops overnight will remain across the south and southwestern portions of the area before greater precip chances begin to spread north and east into the early morning hours of Saturday. High pressure to our north will continue to feed cooler and drier air southward late tonight into Saturday but overnight lows will be held in check by continued widespread cloudiness with upper 30s to low 40s expected from north to south. Short term Saturday through Sunday night As of 340 am est Friday... Saturday will feature competing influences on local temperatures. The aforementioned surface high to the north will get nudged offshore in response to deepening low pressure across the central plains moving northeastward into the midwest. An in-situ cad wedge airmass will be entrenched across the piedmont as widespread clouds and precip help to reinforce the near surface stable layer. At the same time, a warm front will attempt to lift northward as southerly flow ahead of approaching low pressure strengthens. There will likely be a sharp gradient in temperatures across the region on Saturday with upper 30s and low 40s across the far northwest ranging to low to mid 50s across the southeast. Widespread precip is expected over the area on Saturday with categorical pops expected as deep layer moisture is lifted over the near surface cool stable airmass. Focus for heavier rain will shift to the north Saturday night as the warm front makes northward progress. Winds become southerly in the wake of the front with steady rain transitioning to showers after the front passes. A cold front will approach the region on Sunday with westerly winds behind the boundary. Rain chances will come to end as the front crosses the region. Storm total precip will average around 1 inch with the highest totals expected across the southwestern quadrant of the area where 1.25-1.50" is possible. Given the recent wet weather, and what is expected to fall this weekend, we could certainly see some river flooding issues into early next week. Downsloping westerly winds and increasing late-february Sun angle will allow temperatures to warm considerably on Sunday afternoon with upper 60s and low 70s inland and low to mid 60s expected across the eastern shore. Some guidance is showing mid and upper 70s for Sunday, held off on going quite that high with this forecast package but Sunday looks to be a very nice day after this prolonged period of wet dreary weather. Decreasing dewpoints and cooler temperatures will move in for Sunday night with mid 30s to low 40s expected for overnight lows. Long term Monday through Thursday As of 345 pm est Thursday... the flow aloft becomes more zonal across the CONUS early next week, leading to less active wx across much of the country (including our area). Drier (but still around average) Mon mon night as sfc high pressure briefly settles into the region. Still dry seasonable on tue as high pressure moves offshore. Highs on Mon will be in the mid- upper 50s in most areas (except for low 50s on the ERN shore). Lows mainly in the upper 20s-low 30s Mon night W highs rising to around 50 on the ERN shore mid 50s-around 60 elsewhere on tue. Lows tue night range from the low 30s N NW to the around 40 se. |
Models diverge in their solutions for mid-late next week. Latest 12z 21 ECMWF is forecasting high pressure to settle into the plains (w sfc ridging extending to the NRN mid-atlantic region). The ecmwf solution would lead to below average temps and mainly dry conditions (perhaps a chc of light pcpn Wed night-thu). The GFS is much warmer, as it tracks a weak area of low pressure N of the region wed-wed night (bringing light rain), W slightly cooler air settling into the region on thu. For now, went W a model blend from wed-thu and kept slight chc pops in the forecast from wed-thu am (for -ra). Forecast highs are in the 50s on wed, cooling to the mid-upper 40s n low-mid 50s S by thu. Lows mainly in the 30s Wed Thu night. Aviation 12z Friday through Tuesday As of 630 am est Friday... another wave of moisture is streaming northeastward along a stalled frontal boundary across the region. Light rain is fairly widespread across all terminals with the exception of sby where drier low level air resides. Ceilings are largelyVFR this morning with some restrictions MVFR noted across the southwestern cwa. Rain will continue into the afternoon hours before being relegated to southern terminals (ecg) this afternoon. Short-lived visibility reductions are possible in heavier pockets of rain through early afternoon. Did include a tempo group at ecg to cover the relatively higher potential for visibility reduction there this afternoon. Winds will remain out of the northeast through the period, generally AOB 10 knots. Cigs improve this evening but another slug of moisture will approach the region late in the forecast period. Outlook... MVFR ifr conditions in rain, drizzle and fog continue Fri night and Sat as a series of impulses move along the stalled frontal boundary. The boundary moves north as a warm front late Sat keeping unsettled wx conditions into sun morning. A cold front moves across the area sun. Marine As of 350 am est Friday... still fairly benign over the marine area with seas of only 2-3 ft and bay waves 1-2 ft. Will see some increase in winds later this morning as sfc high pressure to the N sags south into the area. Have speeds increasing to 10~15 kt, and 15-20 kt for the southern coastal waters. With nne flow will have to watch to see if seas respond and try to build to 5 ft S of CAPE charles light, but current thinking is that the stronger winds will be short-lived. The sfc high builds into the waters this aftn evening so winds should diminish to only 5-10 kt from the ne. On sat, the sfc high gradually retreats to the ne, as the frontal boundary to the south begins to lift back N as a warm front Sat night. Winds will veer to the SE Sat night then to the sw and increase on Sun as a stronger cold front approaches from the west. SCA conditions appear likely for all zones Sun and sun night (sw winds shifting to the W sustained to 20 kt with gusts to around 30 kt). A period of gales will be possible over the northern coastal waters Sun night into Monday. The offshore flow will keep seas from building much above 5-6 ft. Diminishing winds seas later Mon and Mon night. Hydrology Noting richmond westham rising faster than anticipated this eve. Latest update has the level of rise slowing then leveling off overnight but not reaching flood stage until Fri eve. Held off on a warning ATTM given the updated forecast.
