(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 180814 afdakq area forecast discussion national weather service wakefield va 414 am edt Thu jul 18 2019 Synopsis High pressure remains off the southeast coast through the weekend. A trough of low pressure will cross the region through tonight. Otherwise, hot and humid weather will continue until Monday. Near term through tonight As of 400 am edt Thursday... lingering showers and storms from late last night still hanging on early this morning. Majority of sct showers oriented along sfc trough in place along the SE va NE nc coastal plain early this morning. Only major change in the near term (or short term, for that matter... ) was to add to heat advisory along the coastal plain. Have added all counties along the ches bay rivers for today for heat indices ~105 deg this aftn into this evening. Using met- weighted blend for highs today yields temps about a category lower than yesterday, mainly in the low to mid 90s. This is due in large part to greater cloud coverage and higher TD values. However, those higher dewpoint values (given lesser mixing and aided by rainfall of late last night), will therefore bring similar heat index values, especially along the coast in the advisory area. In fact, dewpoints should remain similar through this evening along the coastal plain. Cams providing a bit of a mixed signal given convective activity today, but do expect sct to numerous showers to re-fire this afternoon into this evening, focused along the coast along the weak coastal trough, where moisture pooling and best lift will be co-located. Have gone with a 40-60 pop for sct to numerous late aftn evening storms, with greatest coverage over the northern neck down to the eastern tidewater. These storms could shorten the duration of the heat advisory in spots, but think convection will be sparse enough initially that most of the day will be within heat advy criteria along the coast hence the expanded area for the heat advy headline. Very warm and muggy tonight. Partial clearing with lows in the 70s. Short term Friday through Sunday As of 400 am edt Thursday... high pressure (both at the sfc and aloft) build from the se coast west into the mid ms valley Friday through the weekend. H85 temps btwn 20-22c bring a mainly capped airmass, suppressing convection for the most part both Fri and sat, though a slight chance has been maintained each day. This could break down a bit across the north on Sunday with some late day storms possible across the piedmont and north of ric. Main concern will obviously be for the extreme heat (highest since 2012) across the lower mid-atlantic region. Highs in the mid-upr 90s nr 100, in tandem with dewpoints in the mid-upr 70s yields heat index values 105-110 well inland, with excessive heat criteria very possible for hampton roads and tidewater areas. The heat peaks on Sat Sun with highs upr 90s- lwr 100s and heat index values ~110-113 (excessive heat warning levels) over much (if not all) of our area. Will continue to highlight this potential in the hwo. Due to these oppressive dewpoints, record highs will be tough to reach but record high lows appear attainable if not likely... See climate below. Long term Sunday night through Wednesday As of 240 pm edt Tuesday... the GFS and ECMWF continue to advertise a developing eastern us trough and a weakening of the bermuda high for early next week, although the trend is a little slower than yesterday. This results in a break in the heat wave after Monday and also with the cold front likely to stall either along the coast or in the carolinas, expect a chance for showers and storms to continue through midweek, especially along SE portions of va and NE nc. The 12z GFS seems climatologically to be too strong in trying to develop a closed low over the tn al by midweek. At this point prefer more of the ecmwf solution with the NE trough being maintained farther to the north with just a weakness lingering between the ridges over the lower ms valley. This would be drier solution for the area for Wednesday into the later portion of next week. At this point have held to chance pops each day with the best chance for rain with the frontal passage from late Monday through Tuesday evening. Temperatures will continue to be very warm on Monday with highs in the low to mid 90s, followed by a drop off into the mid to upper 80s on Tuesday on Wednesday with the front moving through and an increase in clouds. |
Aviation 08z Thursday through Monday As of 200 am edt Thursday... sctd shower or TSTM over SE va and NE nc could affect orf and ecg thru early this morning, so have vcsh in these tafs. Otherwise, expect mainlyVFR conditions at the TAF sites today into Fri morning with SW winds 5-15 kt. There will be the chance for showers tstms this aftn into this evening, as sfc trough lingers over the area. Any showers tstms could produce brief restrictions in vsby along with strong wind gusts. The chc for showers tstms is 20% or less Fri and sat, as high pressure prevails off the SE coast. The chc for showers tstms increases to 20-30% Sun aftn evening, then 40-50% Mon aftn. Marine As of 400 am edt Thursday... overnight SW winds will increase as the trough approaches tightening the pressure gradient a bit. Ssw winds increase to 15 kt with some gusts to 20 kt over ches bay, and 15 to 20 kt in the coastal waters. This will build waves to 2 ft in the bay, and seas to 3-4 ft on the coastal waters. SCA is up for the bay through tonight. There may be a few gust up to 20 kt. The winds will begin to relax to 10 kt on the bay and rivers, and 10 to 15 kt on the ocean waters Thu morning, as the trough of low pressure stalls. Expect more storm activity on Thursday with more of a potential for convective wind gusts for 30 kt or greater Thu afternoon and evening. The pressure gradient will weaken Thursday night, allowing for a winds to decrease to 5-10 kt. This pattern will continue through the weekend. The bermuda high will build back in late on Sunday, in response winds will increase to 10-15 kt (15-20 kt for the oceans zones off the nc coast). Climate Upcoming heatwave may challenge or break record highs and or record high lows (esp from Fri through sun).
