NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jun 28, 9:19 AM EST, 2 hours 56 minutes earlier.
Area Forecast Discussion National Weather Service Blacksburg VA 1019 AM EDT Fri Jun 28 2019 .SYNOPSIS... High pressure will remain across the region today through Saturday resulting in continued hot weather along with widely scattered showers and storms especially across the mountains. A weak cold front should drift south across the region later Sunday before passing into the Carolinas early next week. && .NEAR TERM /THROUGH TONIGHT/... As of 1010 AM EDT Friday... Similar to yesterday and a typical summer day, widely scattered showers and thunderstorms are possible this afternoon, then fading during the evening. The combination of very warm temperatures and light winds will create an unhealthy environment with ground level ozone concentrations running high. An Air Quailty Alert is in effect for NC Foothills and Piedmont counties today. As of 245 AM EDT Friday... Summer scenario remains in place today with soupy low level moisture beneath weak ridging both surface and aloft. However weak cap aloft over strong heating of low level moisture, combined with orographics, wont be enough to limit convection espcly as weak features aloft slide east around the parent mid level ridge offshore. This also in conjunction with forecast high instability and weak convergence along the Blue Ridge suggests another round of at least widely scattered convection espcly mountains where aided by differential heating to start. Latest short term guidance has spotty coverage initially unzipping along the southern Blue Ridge per weak upslope, and across the north where likely some leftover outflow around. Models also then show quite a shotgun pattern to convection this afternoon, with coverage/propagation aided by slow steering that may again lead to mergers and slow moving cells. Also given the degree of instability and potential for outflow to leak off the eastern slopes of the Blue Ridge, appears at least isolated coverage possible in parts of the east. These likely to produce pockets of heavy rain with isolated pulse induced downbursts possible given forecast DCape of 1000+ J/kg. Otrw will continue to run with mainly chance/scattered coverage north and west, with more isolated nature pops east. Highs well into the 80s mountains and low/mid 90s east under developing cumulus buildups, while heat indices only slightly hotter per some dropoff in dewpoints this afternoon. Any lingering storms should again fade this evening given lack of much support but may be until near midnight until all dissipate per leftover progged instability. These should again lead to mainly clear skies with patchy fog around espcly valleys and where earlier downpours occurred. Thus left in low pops during the evening followed by clearing with muggy lows mostly in the 60s to around 70 except a few 50s in the cooler valleys. && .SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/... As of 345 AM EDT Friday... Summer weather pattern will dominate the region during the period. The main synoptic features will consist of a broad upper high pressure system anchored over the central U.S., the westerlies confined to areas north of 40 degrees latitude, and abundant tropical moisture being drawn northward by surface high pressure in the western Atlantic, supplemented by a couple of weak tropical/easterly waves. For Saturday...Upper troughing across the northeastern U.S. will help punch a short wave into the Mid-Atlantic and lower upper heights temporarily. However, this will also enhance the westerly surface winds over the region, tending to suppress convection east of the Alleghany front. Much of the day east of the Blue Ridge will likely remain convection free, but should expect to see an increase in convection across the Alleghanys and northern parts of Virginia by afternoon as temperatures cool aloft and heights fall, in addition to a weak backdoor frontal boundary expected to be across the northern Mid-Atlantic. Some of this convection will linger into the evening and drift southeast into the remainder of the CWA before dissipating by midnight. Despite the decrease in heights aloft, the cool air associated with the front will pass to our east, leaving 850mb temperatures across our CWA mostly in the +18C to +20C range, equating to high temperatures in the 80s west to 90s east and lows mostly in the 60s to lower 70s east as dewpoints linger in the mid to upper 60s across the region. Sunday, northwest flow will continue across the region as the upper ridge remains centered over the Midwest and the northeast U.S. upper trough shifts offshore of the New England coast. An associated back door front will likely linger across the west and southwest part of the CWA by afternoon serving as a focus for convection. On each of these days given the lack of any strong dynamics, thermodynamics with 1000+ CAPES during afternoon heating along with PWATS 1.5-1.75 combined with mesoscale features such as outflow boundaries and weak upper disturbances, along with differential heating will support scattered convection. By Monday, the upper flow will flatten and heights will begin to rise. Moisture will remain abundant and temperatures will remain warm with 850mb temperatures continuing to hover close to +20C if not a bit higher at this point. Isolated to scattered afternoon convection will develop once again, favoring the western areas where dynamics are slightly better and moisture is a bit deeper, along with the differential heating across the Alleghanys. Otherwise, look for another warm and humid day with high temperatures in the 80s west to the 90s east and lows in the 60s west to the lower 70s east. /Confidence in Forecast Parameters/ Temperatures - High, Precipitation Probabilities - Moderate, Thunderstorm Threat - Moderate, Winds - Moderate. && .LONG TERM /TUESDAY THROUGH THURSDAY/... As of 200 PM EDT Thursday... The broad upper ridge will continue to dominate much of the U.S. south of 40 degrees latitude through the period, leaving an overall typical summertime pattern in place with warm and humid conditions along with scattered mainly diurnally driven showers/thunderstorms. Much of the week will feature isolated to widely scattered showers and thunderstorms. As the strong 590 dm ridge begins to build overhead, all upper level wind/shear dynamics begins to move well north out of the region as well. This will promote diurnally driven slow-moving pulse storms, keeping the chance for severe storms to a minimum. Some differences in the models with regards to the ridge exists moving into the latter part of the week. The GFS flattens the ridge while the ECMWF continues to build 590 dm heights over the southeast United States. Some slight troughing is noted on the GFS by Thursday, which could support a better organized chance of storms. The fourth of July should offer very typical weather for our region. Look for scattered afternoon/evening showers/thunderstorms that may dampen a few picnics or fireworks displays. Otherwise, it will not be a washout and until any showers/thunderstorms arrive look for high temperatures in the 80s west to lower 90s east and warm and muggy low temperatures in the mid 60s to lower 70s. /Confidence in Forecast Parameters/ Temperatures - High, Precipitation Probabilities - Moderate, Thunderstorm Threat - Moderate, Winds - Moderate. && .AVIATION /14Z FRIDAY THROUGH TUESDAY/... As of 635 AM EDT Friday... Other than for localized sub-VFR in fog/stratus espcly in the valleys such as KLWB, looking at mainly VFR to start this morning with just some mid/high clouds around outside of any strato- cumulus. Expect any low conditions to quickly improve by mid morning if not sooner as strong heating gets going. Rather similar scenario to Thursday again this afternoon with cumulus fields across the mountains early on leading to some CB buildups and isolated to widely scattered showers/storms. This mainly along or near the Blue Ridge between mid to late afternoon, and tending to re-develop along rain- cooled outflow heading to the south and east. Local sub-VFR restrictions possible if any of these impact a terminal which looks most likely across the mountains. Thus included a VCTS mention at KBCB/KROA and KBLF where chances of seeing a storm appear highest. Leaving out in the east where confidence remains lowest espcly in the KDAN vicinity at this point. Winds mainly light and variable for most of the day outside of any convection. Any thunderstorms should fizzle shortly after loss of heating with a return to overall VFR by mid/late this evening. Will again see patchy fog develop espcly in areas that see rain during the day and locations near river valleys including KLWB where IFR or worse appears possible into daybreak on Saturday. .Extended Aviation Discussion... On Saturday, the chances of sub-VFR conditions again increase especially across the mountains with heating of low level moisture aided by orographics. The arrival of a backdoor cold front late in the weekend should allow for an increase in coverage of showers and storms perhaps Saturday night over the mountains and elsewhere Sunday afternoon. VFR will return behind the front with only isolated showers possible south/west of the Taf sites Monday and Tuesday. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
