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 Jul 3, 1:10 PM EDT, 1 hour 53 minutes earlier.
Area forecast discussion, Jul 3, 1:10 PM EDT, 1 hour 53 minutes before
Area Forecast Discussion National Weather Service Blacksburg VA 110 PM EDT SUN JUL 3 2016 .SYNOPSIS... A weak stationary front across the Carolinas will remain south of the area today and tonight. The front will advance northward as a warm front on Monday. This boundary will allow storms to track into the region Monday and Tuesday. && .NEAR TERM /THROUGH TONIGHT/... As of 1100 AM EDT Sunday... A weak shallow wedge will remain through the day especially along and east of the Blue Ridge north of 460. Low level easterly flow is up through 2000 feet, westerly above the wedge. A vast majority of the sounding is saturated through 20,000 feet. For the majority of the day, expect low clouds and cooler than normal temperatures. Areas north of highway 460 will see passing rain showers this afternoon and evening. South of 460, particularly the Mountain Empire, the wedge may erode allowing clouds to break late this afternoon. This area may see a few thunderstorms into this evening. If clouds can break along and south of the VA/NC border by this evening, a few thunderstorms may track there as well. For now, clouds are limiting instabilities to keep severe threat low. As of 245 AM EDT Sunday... Wave currently producing clusters of deeper convection that are exiting the southeast sections attm should slide east early this morning taking best lift to the east. Behind this feature, will see high pressure fill in from the north resulting in the development of a decent low level wedge over eastern sections today into tonight. This should limit added shower coverage in the east through this afternoon while corridor of deeper instability will take shape on the west side of the wedge, along the interstate 77 corridor. Even there support rather limited this afternoon, but most meso solutions suggest things may unzip from north to south western third through the afternoon espcly along the 850 mb theta-e gradient. Thus running with the highest chance pops there with scattered coverage out east, where will remain rather stable with main lift above the developing cool pool. High temps very tricky today given such a warm/soupy start followed by increasing easterly flow Blue Ridge east, and a more southerly trajectory to the west. Given tendency of the Nam to do best in this scenario, followed closer to the Met mos highs with some upward tweaks based on current obs. This results in a range from only low/mid 70 northeast to 75-80 Blue Ridge to around 80 far west, pending just how widespread low clouds are early, and whether any breaks develop out east at all later. This could result in highs only in the upper 60s LYH vicinity. Area basically remains in between support overnight with the front to the south and an initial wave with a likely MCS working toward the Ohio Valley late. Guidance showing some weak lift overtop the lingering wedge but only enough for spotty showers early after any evening convection southwest, and perhaps a band of heavier rainfall far north/northwest late if convection develops along the baroclinic zone in advance of the upstream impulse. This southward scenario seen more so with the latest ECMWF and less with other solutions including the SREF. Otherwise think best chances reside over the southwest early on per weak upslope flow, and then late with some spillover from the northwest. Otherwise cloudy and muggy with lows mostly in the 60s. && .SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/... As of 310 AM EDT Sunday... Main period of concern during the holiday as the boundary lifts back north as a warm front during the day while complexes look to traverse in from the west with the upper system heading out of the midwest. Biggest question is just how far south the axis of very heavy rainfall will establish given more of a westerly vs northwest trajectory aloft and the front sliding farther north. Models have continued to trend north with the corridor of deeper convection with now only the bottom edge of the heavier rainfall clipping our wetter northwest counties. This looks to also be a combination of showers early Monday, and then more outflow induced deeper convection along the bottom edge of the main lift to the north late Monday. Elsewhere appears convection will be more scattered nature to the south of the main lift along the jet with moisture convergence being driven along the departing boundary during heating Monday afternoon. This looks to affect more of the western/northern counties with less QPF to the south and east for now. However likely more of a severe threat Monday afternoon as soundings show decent unidirectional flow aloft above increasing instability including some dry air aloft. Could also be a tight gradient in coverage including QPF Monday with likely/categorical pops to start northwest, then likely/categorical swinging through the west/north during the afternoon with only scattered coverage elsewhere. Based on continued high pwats, any convection would again result in heavy rainfall with the highest threat again over the more flood prone northwest counties. However based on the northward shift in more organized heavy rainfall, and some increase in FFG this past week, appears threat may be more localized and would prefer another run before hoisting a flash flood watch at this point. Highs mostly upper 70s to mid 80s except perhaps some upper 80s far south, where a surge in warm advection will occur under more insolation behind the exiting front a bit sooner on Monday. Appears scattered convection will persist into Monday night but will again may be in a void region between the front to the north and a trailing band of shra/tsra swinging in from the northwest behind a second wave across the Mid Atlantic. However just how fast this band spills southeast remains in question given strength of the convection and how far north the second wave ends up going. Therefore continuing trend of likely or higher pops northwest third espcly Monday evening with mostly chance or less central/southern sections where could be even less coverage. By Tuesday, the main short wave that will cause the heavy rainfall and severe weather potential on Monday will be northeast of the region moving off the northern Mid-Atlantic coast. However, a trailing front will be left behind and draped across the region from northern VA into eastern TN and points southwest. While the main dynamics have shifted away from the region, thermodynamic profiles for Tuesday actually look more favorable for strong to severe thunderstorms than Monday. However, with the lack of forcing, not clear how much there will be. Nonetheless, with the frontal system drifting through the CWA during peak heating, thunderstorms are expected and a few strong storms with heavy rainfall can certainly not be ruled out given the high CAPES and high PWATS remaining in place. By Wednesday, increasing ridging aloft is noted by most models as a subtropical ridge continues to build westward into the southeastern U.S. from the Bahamas. Unfortunately, a weak surface boundary lingers across NC into the southeast states, a common occurrence recently. Given the high pressure aloft to the south, it is very unlikely that this boundary will make any further progress to the south, more likely just wash out. Nonetheless, the boundary combined with diurnal heating will likely continue to trigger afternoon showers and thunderstorms. Activity will likely tend to be more numerous across the western mountains and may linger into the evening/overnight hours in the west. Have tailored pops accordingly. Temperatures will be held down somewhat Tuesday because of cloud cover and precipitation, but begin a trend upward through the remainder of the period as 850mb temps creep toward +20C. Look for max temps mostly in the 70s to lower 80s west and mid to upper 80s east Tuesday creeping up about 5 degrees by Wednesday. Lows will remain well above normal with high PWATS/RH values, mainly in the 60s to lower 70s. && .LONG TERM /THURSDAY THROUGH SATURDAY/... As of 515 AM EDT Sunday... Some differences noted between the GFS and the ECMWF, but the main focus through the period will be on a building subtropical ridge across the southeast states with gradually increasing heights. The westerlies are generally relocated further north than they have been in recent weeks, mostly north of 40 deg. latitude. This will tend to remove the most active weather and MCS potential from our region and locate it further north. However, the ECMWF especially, depicts a strong short wave Thursday that could temporarily push the westerlies further south and potentially allow another MCS to drift into at least the northern portion of the CWA Thursday. Too much difference among the GFS/ECMWF to put much confidence in this just yet. Clearly through the remainder of the period, Friday through Saturday, heights continue to build and approach 590dm as 850mb temps rise into the +20C to +22C range. There is no appearance of a wedge in the pattern, so it could be quite toasty during the later half of the week. MEX guidance has highs in the 90s even at BCB late in the week with lows in the 70s. These temperatures will be about 7-10 degrees above normal. Thunderstorm activity should become increasingly diurnal in nature after Thursday with little forcing evident. && .AVIATION /17Z SUNDAY THROUGH THURSDAY/... As of 110 PM EDT Sunday... Poor flying conditions will continue across much of the region this afternoon with a low level wedge resulting in IFR/LIFR cigs in stratus as well as MVFR/IFR vsbys in fog and showers. Latest guidance quite slow to lift IFR cigs espcly Blue Ridge east this afternoon as easterly flow keeps the cool pool in place. Thus will trend most locations toward IFR/MVFR cigs lingering from KBCB east, while cigs/vsbys rise to VFR at KBLF, and perhaps KLWB as warmer air rides up along the western mountains. Added deep convective threat appears less out east this afternoon and evening with better chances over the west where will see more heating/instability. For now will keep going trend of having more showers mountains, followed by developing shra/tsra late this afternoon, but mostly MVFR and without thunder mention out east for now. Wedge will linger tonight with conditions likely spilling back into MVFR/IFR and possible LIFR in lower cigs/fog along with lingering showers or patchy light rain. Extended discussion... The front will remain stalled over the region Monday into Tuesday which may yield some heavier rain and storms at times as complexes of showers and thunderstorms spill east. Overall VFR outside storms except more widespread sub-VFR possible later Sunday into Tuesday, and at night with fog/low clouds. Ridging should finally strengthen over the area by midweek resulting in more widespread VFR including more diurnally driven afternoon/evening convection and subsequent periods of MVFR. && .RNK WATCHES/WARNINGS/ADVISORIES...
