(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 231106 afdakq area forecast discussion national weather service wakefield va 706 am edt Tue jul 23 2019 Synopsis A strong cold front crosses the area today as low pressure tracks across north carolina. High pressure builds in from the north Wednesday through Friday. Near term through tonight As of 655 am edt Tuesday... latest upper air analysis shows a deep upper trough centered from ontario to the ERN midwest slowly moving eastward. At the sfc, low pressure was centered from nj to long island, with the trailing cold front extending SW to fci-fvx-nw nc. A second sfc low pressure center has started to develop over ERN tn WRN nc. Closer to our area, there are some pre-frontal showers across the ERN cwa, with an area of steadier rain behind the front in the va piedmont mountains. Temperatures have fallen into the upper 60s across the NW piedmont, but are still in the mid 70s- around 80f over SE va NE nc. No significant wx expected in the from now through midday noon with just a steady light-moderate rain across northern western zones and ongoing (scattered) showers across the se. While skies will remain mostly cloudy (even ahead of the front) through much of the day today, there will be enough Sun for temperatures to quickly rise into the 80s across SE va NE nc. Highs will mainly be in the 70s (w temps dropping into the 60s at times) over the NRN two-thirds of the cwa. As the front moves into SE va by this aftn, numerous showers tstms will quickly develop along it, with mainly light-moderate rain continuing from central va to the nrn CWA border. The front is expected to slow down as it crosses SE va (and eventually NE nc) later this aftn-this evening in response to a developing area of sfc low pressure tracking ene across nc during the day today. With precipitable water values AOA 2 inches and the flow aloft nearly parallel to the slow-moving frontal boundary, am still concerned about the potential for training storms. Storms will initially be discrete but are expected to quickly evolve into a line be late aftn. The href continues to forecast 30-50% probs of >3" 3 hours (with the focus across SE va). Given relatively dry antecedent conditions across far SE va, will hold off on issuing an flash flood watch, as the ground (especially over rural swampy areas) should be able to handle a decent amount of rainfall. However, there is a relatively high chc of at least some localized flash flooding in urban populated areas from hampton roads to norfolk va beach. The potential for flash flooding will need to be monitored and a short fused flash flood watch may need to be issued. Qpfs through tonight range from 2-3" across the SE to 0.5-1.5" N of i-64. There is also a marginal-slight risk of severe wx across se va NE nc this aftn. Wind fields aloft increase as the upper trough digs across the eastern half of the country, allowing a 40-50kt 500mb jet to move over the area. This wind field combined with any afternoon heating will be enough for a few strong to severe storms. However, the big limiting factor will be the weak mid level lapse rates owing to the very moist atmosphere. The best chc of severe wx will likely occur when the cells are discrete initially (mainly from 17-21z). Tstms eventually move into NE nc by evening as the front slowly moves se and low pressure moves toward the NE nc coast. The front finally clears the CWA by 00-03z Wed as the low moves offshore. Showers end from NW to SE tonight as the low slowly pulls away from the coast. Lows tonight mainly in the 60s (w upper 50s possible across the NW piedmont and low 70s in coastal SE va ne nc). Short term Wednesday through Thursday night As of 355 am edt Tuesday... high pressure slowly builds in from the north on wed, before becoming centered over the area late thu. One cannot rule out scattered showers and isolated storms right through Wednesday |
across coastal zones as the upper trough axis approaches the area on wed. Kept pops mainly in the slight chc range, as the latest guidance shows that any appreciable deep-layer moisture will remain to our south and east. It will remain dry across inland zones on Wed (and dry in all areas from Wed night through Thu night). Temps will be below average on Wed thu, with highs mainly in the 82-85f range (and lower humidity). Lows Wed Thu night mainly in the low-mid 60s inland (while remaining around 70f along the immediate coast of SE va NE nc. Long term Friday through Monday As of 345 pm edt Monday... quiet and quite pleasant weather expected for the extended with high pressure in control through the week and weekend. Will keep with a dry forecast thu-Monday. Temps will slowly trend upwards starting out in the mid 80s Thursday, then gradually rising to the lower 90s Sun mon. Very seasonable for late july. Aviation 12z Tuesday through Saturday As of 700 am edt Tuesday... scattered shras are ongoing throughout the area this morning and cigs are starting to fall into the MVFR range. A cold front (currently just S of ric) continues to cross the CWA from NW to se through late evening. CIGS likely fall to ifr at ric by 15-16z, while remainingVFR MVFR elsewhere. Expect tstms to develop along the front during the midday-aftn (likely over se va at first), with mainly shras and a slight chc of thunder n of the front. The front slows down later this aftn-this evening as it approaches NE nc, with tstms expected to continue along it. Tstms move SE of the terminals by 00-03z wed, but scattered-numerous shras will continue through 06-09z near the coast and across the se. Pcpn likely ends at ric by 00-03z wed. Cigs drop to MVFR at all sites by aftn (w prevailing ifr cigs likely continuing at ric). Prevailing ifr CIGS are possible at sby phf orf by early evening, but confidence is too low to include in the tafs. Vsbys in shras will mainly be 3-6sm, but ifr lifr vsbys are likely in any tstm. Have added tempo groups of tsra at phf orf ecg in the 18-00z timeframe due to high confidence. Conditions improve from nw-se tonight-wed am.VFR expected from wed-fri. Marine As of 220 am edt Tuesday... a cold front will be slow to push across the local waters through late today. SW winds 15-25 kt starting out...
