What forecasters said that day
The local office's own words before this flash flood watch 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 flash flood watch went out at May 18, 2:14 PM EDT, 9 minutes earlier.
Area forecast discussion, May 18, 2:14 PM EDT, 9 minutes before
Area Forecast Discussion National Weather Service Blacksburg VA 214 PM EDT Mon May 18 2020 .SYNOPSIS... A complex area of low pressure extended from the upper Midwest into the Mid-Mississippi valley. This area of disturbed weather is expected to consolidate into one large cutoff Low over the Lower Ohio and Tennessee Valleys by tonight. This Low is expected to remain nearly stationary through mid-week which will favor a prolonged period of rain and the possibility for flooding. Tropical Storm Arthur was centered off the southeast Atlantic Coast. The center of Arthur is expected to move northeast and remain offshore today with rain impacts mainly to the Tidewater area. && .NEAR TERM /THROUGH TONIGHT/... As of 923 AM EDT Monday... A complex weather pattern this morning with frontal boundary with its associated low center and Tropical storm Arthur moving up the coast. Surface obs showed that backdoor front has pushed into South Carolina this morning. This morning RNK 12z sounding showed that the cool wedge moisture was shallow and low level east flow. This should mixed out to allow some sunshine. Adjusted cloud cover in the west for this morning to allow for some sunshine in grids. Adjusted temperatures this morning into this afternoon utilizing the latest surface obs, their trends and blended in the NBM. High temperatures are tricky today because of cover clouds and precipitation and its placement. More changes later this morning... As of 400 AM EDT Monday... Weather map is rather busy looking this morning with Tropical Storm Arthur just off the North Carolina Coast. Low pressure was also centered over Illinois with a second, but not as pronounced, area of low pressure near the MS/TN border. A surface trough connected these two Low pressure features, in addition to a stationary front which extended from the Low over IL across the upper Ohio Valley then curving south along the spine of the Appalachians to about Bluefield, WV, before arcing in the classic wedge fashion to the east coast bisecting western VA and northern NC. North of the wedge front, winds have become northeasterly with cooler air moving down the east side of the Appalachians from Pennsylvania into northern and central Virginia. For today, our weather will be focused along the wedge front which will likely become aligned with I-77 by this afternoon. In spite of the relatively cool stable air entering the CWA from the northeast, there will be a surge of moisture aloft from the southwest, associated with the Low moving northeast from the Mid-MS valley. Convergence associated with these features is expected to result in increasing shower activity with the greatest coverage later in the day and into tonight. Instability for thunderstorms looks like it will be mainly confined to areas along and southwest of the wedge front, along and west of I-77. For tonight, a consolidation of Low Pressure will take place over the Lower Ohio and Tennessee Valleys. A persistent fetch of southeasterly upslope flow will then develop across the central and southern Appalachians, setting the stage for a prolonged period of cloud cover and rain. Current thinking is the rain which falls today and tonight, unless it becomes convectively driven will work only to prime the pump with respect to ground saturation process. That said, the area to watch if there is to be flooding tonight is the NC mountains. This is where the convective threat is the greatest, aided by the increasing southeast upslope flow. QPF of 1.5 to 2.5 inches is expected for the North Carolina mountains tonight, with lesser amounts to the north and east into VA/WV. With the exception of areas west of I-77, favored the cooler side of guidance for temperatures today and tonight. Deepening northeast to easterly flow in addition to cloud cover should limit solar insolation. The only caveat is the subsidence region around T.S. Arther. This subsidence may scour the low level cloud cover over the piedmont. If this occurs, then forecast temperatures may be too cool. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... As of 200 PM EDT Monday... Ensemble and deterministic guidance is remaining consistent on the upcoming pattern. Closed/vertically stacked upper-level low will be dropping south into the Tennessee River Valley, stalling just to our west. Meanwhile, strong high pressure to the north will begin to wedge down the eastern side of the Appalachians. This will allow for continuous southeast flow of deep moisture off the Atlantic as the low level jet begins to strengthen. This could supply for copious amounts of rain from NW North Carolina mountains to the southern Blue Ridge in Virginia in the next few days. Guidance (hi-res, global, and ensembles) has been in very good agreement and has been fairly consistent in showing an increasing southeast low-level jet beginning Tuesday morning. This jet strengthens to 40-50 kts and remains oriented perpendicular to the mountains for multiple days. Meanwhile, strong fetch of deep moisture will be advected northwest from the Atlantic, running into the southern Blue Ridge. This strong lift between the squeeze play of the wedge of high pressure to the north, strong low level jet, and additional orographic lift affects from the mountains will likely supply fairly significant multi-day rainfall amounts for North Carolina mountains and northward into Virginia. For QPF, went with a blend of WPC, but also took the GFS/EURO and NAM into account, with some manual upward adjustments along the southeast flow upslope favored areas along the southern Blue Ridge. With the amount of rain expected, there is some concern for flooding, especially along the main stem rivers. River ensemble forecasts have also been advertising some main stem river flooding later in the period as runoff begins to increase and accumulates within the river basins. Flash flooding may also be a concern too if any convection/higher rain rates can work its way into the area. However, the cool air wedge in place may "save" us from from much of the deeper convection that would otherwise work its way in, but any heavier rates towards the latter portion of the period could cause quick rises in streams/rivers as the ground will already be very saturated. As mentioned above, the area will be well entrenched into a cool air wedge. Coupled with the clouds and rain, expecting temperatures to be well below normal Tuesday night and Wednesday, with some locations not making it out of the 40s on Wednesday. Otherwise, will begin seeing a warming trend starting by Thursday as the wedge begins to break down. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 200 PM EDT Monday... Closed off upper level low still to our west on Friday, with signs of a kicker to get the upper-level low moving again. Models have been indicating that the closed low finally exits the region for the weekend, with ridging beginning to build back in overhead. Much more of a typical late spring/early summer pattern looks to build back in with the jet stream retreating to the north. Increasing temperatures, humidity, and daily chances of afternoon showers and thunderstorms are the main story, with no major synoptic systems expected through the end of the period. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... As of 127 PM EDT Monday... VFR-MVFR conditions this afternoon will transition to IFR-LIFR for tonight into Tuesday. Expectation is for poor aviation conditions for much of the upcoming week. Combination of a cutoff Low which will take up residence over the Lower Ohio - Tennessee Valleys and a fetch of maritime air which will run up against the central and southern Appalachian from the southeast will result in persistent cloud cover, along with areas of rain and drizzle. Isolated thunderstorms are possible in the western mountains. Winds are expected to remain ENE-ESE through the period at speeds of 8-12kts with low end gusts possible from time to time, especially at BLF and LYH. Moderate to high confidences in ceilings, visibility and winds during the taf period. Extended Aviation Discussion... A cutoff low will remain over the region through mid-week, and possibly into Thursday and Friday. Overall a very poor week with respect to aviation concerns with widespread low ceilings, variable visibilities, and periods of rain, which could be moderate to heavy at times. Scattered MVFR showers are possible in the west on Saturday. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
