The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Blacksburg, VA wrote its last area forecast discussion before this severe thunderstorm warning went out at May 1, 1:34 PM EDT, 3 hours 43 minutes earlier.
Area forecast discussion, May 1, 1:34 PM EDT, 3 hours 43 minutes before
Area Forecast Discussion National Weather Service Blacksburg VA 134 PM EDT Sun May 1 2022 .SYNOPSIS... A cold front will move across the region today, bringing scattered showers and thunderstorms, with a few severe storms possible in the afternoon and evening. Additional showers and storms are expected Tuesday. && .NEAR TERM /THROUGH MONDAY/... As of 130 PM EDT Sunday... Prefrontal showers entered the mountains this morning and are now moving east of the Blue Ridge this afternoon. We should see an uptick in intensity of storms as southerly flow and warm advection has warmed temperatures into the upper 70s to lower 80s. Instabilities, deep layer shear, and mid-level lapses rates are modest this afternoon, but can not rule out a few storms becoming strong to severe, especially across the foothills and piedmont of south-central Virginia and northern North Carolina. Severe Thunderstorm Watch #176 is now in effect until 900 PM. No widespread hydro issues are expected due to dry antecedent conditions and thirsty vegetation; however, high rainfall rates from stronger storms could lead to localized flooding and ponding on roadways. Showers and thunderstorms will exit the piedmont this evening. Another line of showers, associated with the actual cold front, may move across the area overnight. These storms will be weaker and may not move past the Blue Ridge. Dry high pressure will follow the front for Monday. High temperatures Monday will range from the mid to upper 70s across the mountains and low to mid 80s east of the Blue Ridge. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 100 PM EDT Sunday... ...Showers and thunderstorms are possible Tuesday and Wednesday as a low pressure system passes across the region... Expect generally dry conditions Monday night, perhaps isolated showers toward dawn, as high pressure shifts east across New England. By sunrise Tuesday, another low pressure system will be progressing east up the Ohio River Valley, drawing a warm front northward across the lower Mid-Atlantic, resulting in spotty afternoon and evening showers/thunderstorms. Better instability for strong storms appears to be across the Piedmont, where afternoon high temperatures will reach the low/mid 80s. Elsewhere, look for highs in the mid/upper 70s. Expect only spotty showers across the region Tuesday night as the associated cold front approaches, with shower activity ramping up Wednesday morning as the front passes east across the central Appalachians. Again, will have to keep an eye out for a few strong thunderstorms developing ahead of the front during mainly the afternoon and early evening, with the front then expected to clear to the east by sunset. Perhaps a few lingering showers across the mountains to contend with Wednesday night, but much of the area will then have a brief break in the rain chances through dawn Thursday. && .LONG TERM /THURSDAY THROUGH SATURDAY/... As of 115 PM EDT Sunday... ...A deep low pressure system will bring the potential for widespread rain toward the end of the week... High pressure will pass quickly across the Great Lakes to New England on Thursday, and will eventually build southward across the Mid-Atlantic Thursday night and settle against the eastern face of the Appalachians, all of this ahead of yet another low pressure system approaching from the Midwest. Weather forecast model consensus is beginning to converge on Friday and Saturday as the better chances for widespread rainfall associated with this system, but it remains difficult at this point to get more specific than that. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 130 PM EDT Sunday... A line of showers and thunderstorms will move across the area today. Showers have already moved across southeastern West Virginia (KLWB/KBLF) this morning, limiting severe potential this afternoon. Stronger storms are possible across the foothills (KROA) and piedmont of south-central Virginia and northern North Carolina (KLYH/KDAN) this afternoon. MVFR to possible IFR visibilities are likely with the stronger storms. Storms this afternoon may also produce gusty winds. A cold front pushes through overnight with westerly winds developing and becoming gusty late in the TAF cycle/towards Monday morning. Extended Aviation Discussion... Monday will be one of the dry days with VFR conditions expected by late in the day. Another front will cross through the area with a chance of showers and thunderstorms and the potential for MVFR conditions on Tuesday, especially in the mountains. The chance of showers and MVFR ceilings will extend into Thursday. Timing and extent of rainfall and sub-VFR conditions is much more questionable on Thursday. && .RNK WATCHES/WARNINGS/ADVISORIES...
