NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Sep 29, 1:51 PM EST, 1 hour 58 minutes earlier.
Area Forecast Discussion National Weather Service Blacksburg VA 251 PM EDT Tue Sep 29 2020 .SYNOPSIS... A cold front that extended from upstate New York to the Florida panhandle early this afternoon will move slowly east today and tonight bringing a prolonged period of showers and thunderstorms to the Mid Atlantic region. Cooler and drier high pressure builds in for Friday through Sunday. && .NEAR TERM /THROUGH WEDNESDAY/... As of 247PM EDT Tuesday Our frontal boundary remains stalled along the WV/VA line this afternoon with low pressure just to our south over the Great Smoky Mountains. Waves of showers and storms continue to move along the boundary in a south to north northeasterly direction. Currently as of 1815z convection is ongoing with what looks like a meso-low feature across the North Carolina foothills. Out ahead ahead of this feature and the front there is plenty of storm fuel to work with Temperatures from Lynchburg to Danville continue to sit around 80 degrees with CAPE values of 1000-2000 j/kg. Bulk effective shear also remains strong at 40-45 kts good Q-vector forcing and a strengthening upper jet overhead. With that said, the Storm Prediction Center, continues to highlight this area in a marginal risk for severe weather. Locally damaging winds look to be the primary threat heading into the 4-7pm timeframe especially in areas east of the US-29 corridor where better instability resides. Further north into the New River and Roanoke Valley the air is a bit more stable with limited thunder but some training for ponding of water.Rainfall amounts of up to 0.75-1.5" have been observed prompting localized poor drainage flooding concerns. Rain has let up up somewhat west of these locations as temperatures fall into the upper 40s and low 50s behind the front. Life behind the front, shows cold air advection that has already started in over the western mountains and northern sections of North Carolina. This will keep temperatures in the 50s and low 60s in those locations for the rest of the day with lows falling into the mid to upper 40s. Both hi-res and synoptic guidance depict a bit of a faster progression of the front to the east as we get beyond 02- 04z Wednesday morning. The GFS is still the fastest here with the NAM and Euro lagging slightly behind. Best guess at this point looks to be after 2am from west to east across the area. Some leftover pockets of light drizzle may be noted especially in areas out toward the Piedmont. Gusty northwesterly breezes will takeover in the mountains through the overnight into Wednesday as drier/cooler air filters in. Overnight lows look to fall into the mid to upper 40s out west with low to mid 50s out east. Once again these numbers will be dependent on the placement and overall passage of the front with the highest confidence in cooler values west of the I-81 corridor. Some leftover clouds Wednesday mornings as high pressure takes the wheel. SKies should clear out quickly by mid to late morning with sunny skies for the afternoon. Sweater weather returns with cold air advection draining in as temperatures should recover back into the upper 60s to low 70s out east and low to mid 60s out west. Confidence remains moderate to high in the near term with uncertainty to overall progression of the front as it pushes east. && .SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/... As of 200 PM EDT Tuesday... Trend to drier/less humid and cooler weather Wed night, though another trough/shortwave digs across the Ohio Valley Thursday pushing another front through. Models entertain at least isolated to scattered showers Thu afternoon/evening mainly east of the mountains, as flow backs ahead of the front and wave of low pressure develops along the front across NC. Expect mainly clear skies Wed night with increasing clouds Thursday into Thu evening followed clearing Thu night. Lows Wed night will range from the upper 40s to lower 50s west, to lower 50s east. Thursday should be milder ahead of the front, especially east, with highs from the lower to mid 70s east, to lower to mid 60s west. Cooler air advects in behind the front Thu night, but the coolest air doesn't arrive til after this period. Lows Thu night will range from the lower to mid 40s west, to lower 50s east. Forecast confidence is high for this period. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 200 PM EDT Tuesday... Broad upper trough stays in place east of the Rockies and should keep our forecast area in a cool pattern. Strong surface high builds in by Saturday morning, potentially bringing a frost for portions of the mountains, maybe even a few 32 or lower in valleys like Burkes Garden. Another shortwave digs across the midwest Sunday and models close off a low over the Ohio Valley by early Monday, with associated front and surface low pushing across the southern Appalachians. At the moment models are somewhat different on intensity of surface features, with the 00z Euro more robust and having a fairly decent shot of showers by Monday morning with the GFS weaker. Will lean overall toward a blend of the two until we get closer, so at the moment look for isolate to scattered shower threat late Sunday night into Monday, with high pressure again building in Tuesday. Lows will run about 10 degrees below normal Sat and Sun morning with 30s in the mountains to lower to mid 40s east, then warming into or through the 40s for Monday and Tuesday morning. High temps will also run about 10 degrees on average Fri-Sun, then warm to about 5 degrees below normal early next week. Friday and Saturday will see highs in the 50s in the mountains, maybe even some 40s in the highest terrain, with 60s east, warming through the 60s Sunday-Tuesday. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... As of 203 PM EDT Tuesday... A cold front will continue to slowly push through the area this afternoon with a wave of low pressure riding along the boundary this evening into the overnight hours. Predominantly MVFR visibilities at most of the TAF sites with occasional pockets of IFR and LIFR over the western mountains from KHSP to KBLF and KBCB. Thunderstorms continue to be a threat this afternoon over the Virginia and North Carolina Piedmont since this area remains quite unstable out ahead of the incoming boundary. Opted to leave in VCTS conditions at KDAN while adding VCTS at least through the early evening for KLYH. I also added a TEMPO for TSRA during the 21z-23z window at both of the aforementioned VCTS TAF sites above especially with ongoing convection around KUKF and KGEV. Hi-res models such as the NAM3km and HRRR continue to the worst of the activity though off to our south and east toward KRIC where the better storm fuel resides. Besides the rain and storm chances we have the wind to worry about. Since the front will be slow to pass the overall timing of a wind shift will remain a bit uncertain. This largely due in part to the surface wave that looks to ride the boundary from KDAN to east of KLYH and KCHO late tonight into early Wednesday morning. Hi-res models and synoptic guidance continue to hint at a passage between 02-04z Wednesday morning which means a northwesterly wind shift won't takeover at the eastern TAF Sites of KLYH and KDAN until around 06- 08z Wednesday morning. The higher elevations though look to remain with gusts upwards of 20-30kts through the overnight period into Wednesday afternoon. Ceilings and vsbys look to improve back to VFR by 14-17z afternoon as high pressure settles in. .Extended Aviation Discussion... High pressure brings improvement to flying conditions through the start of the extended period as cooler and drier air settles in. There could be late night fog at LWB/BCB and sheltered valleys Thursday morning. The next chance of rain arrives Thursday night and Friday but with limited impact on flight conditions. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
