NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jun 10, 12:40 PM EST, 1 hour 2 minutes earlier.
Area Forecast Discussion National Weather Service Blacksburg VA 140 PM EDT Sun Jun 10 2018 .SYNOPSIS... A frontal boundary will drift very slowly south through the first half of this week, extending from the Ohio Valley to the Mid-Atlantic today, gradually shifting south into central Virginia by Monday morning, and south to the North Carolina/Virginia border by Tuesday, then stall and eventually dissipate during midweek. Scattered showers and thunderstorms will continue each day in association with the front and weak upper-level disturbances, most numerous during the afternoon and evenings. && .NEAR TERM /THROUGH TONIGHT/... As of 1142 AM EDT Sunday... Visible satellite showing cu starting to blossom across the North Carolina High Country and the mountains of West Virginia, southward toward Burkes Garden and Big Walker Mountain. The 12z Namnest showing this fairly well with convection firing in between noon and 1pm similar to yesterday. Storm motion today will also be weak around 10 kts from the west. PWATS running from 1.2" in the mountains to 1.6" in the east will mean again heavy rainers and potential flooding, but again coverage is not widespread enough to warrant any flash flood watches. More organized convection still looks to stay north of our forecast area closer the front from Indiana to PA/MD. There are smaller MCVs across TN/KY which shifts east into the southern/central Appalachians by late afternoon, and this could enhance the lapse rates enough to bring some isolated wind damage, marginally large hail. The Storm Prediction Center has a marginal risk of severe as far south as the NC/VA border. Overall pops updated to reflect closer to a scattered shot of storms, with higher pops along the Blue Ridge, then increasing toward the west after 4pm-5pm. Rest of forecast on track with very warm temps. Previous discussion from early morning... The synoptic situation has changed little during the past 24 hours. A weak west-east oriented frontal boundary remains well to our north near the PA/MD border back west into the Ohio Valley. The front is actually a bit further north than previously expected, which will impact the forecast slightly. Aloft a very weak pressure pattern remains in place with 500mb heights from the Gulf Coast to the Canadian border only varying by around 10dm. A series of weak low pressure disturbances aloft are embedded in a weak northwest flow across the northern tier of U.S. states. These will help to (1) keep the front moving very slowly south over the next couple of days and (2) enhance shower and thunderstorm activity. The convective activity will remain largely diurnal, but given the moist around 1.5 PWATS in place and modestly unstable atmosphere, a pop up shower or thunderstorm is not out of the question at any time, But clearly, the best coverage will be in the 18Z-02Z time frame each day. The two main concerns remain that of (1) excessive rainfall and (2) isolated severe. The excessive rainfall potential is discussed in the "Hydro" section below. With regard to the severe threat, feel that this will remain limited and agree with SPCs marginal outlook in place today and Monday. Just as we saw Saturday, storms will be largely pulse and efficient rain producers, but an isolated downburst or marginally severe hail could occur with the stronger cells that build enough vertical height. With MUCAPE in the 1000-2000 J/KG range and DCAPE as seen from the RNK 00Z sounding around 600 J/kg, severe downbursts will be possible, but not likely or widespread. The sounding remains largely moist adiabatic. With temperatures again well into the 80s today, would expect similar values again today. Thunderstorms will be most numerous again today mainly north of U.S. 460, or north of a JFZ-BCB-LYH line. Temperatures will remain a bit above normal, especially low temperatures with lows mainly in the 60s, lower 60s mountains to near 70 Piedmont, with high temperatures mostly in the 80s, 70s mountains to upper 80s Piedmont. /Forecast Confidence levels/ Temperatures - High Precipitation Chances - Medium to High Thunderstorm Chances - Medium to High Cloud Cover - Medium to High Wind Direction - Low Wind Speed - High && .SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/... As of 330 AM EDT Sunday... The cold front will remain north of the area on Monday, then wedge south overnight. The GFS is the fastest of all models moving the front into the area Monday afternoon, while other models wait until the evening. We are planning to go with the consensus and not the GFS for the Monday-Monday night time frame. However, the outlier GFS is not quite out to lunch if the front jumps to a surface trough/reflection over North Carolina. Typically, a front tracking north to south during the warm season has a tough time moving south into very warm air, especially during peak heating. As the front stays to the north, strong afternoon heating and buoyancy will generate showers and thunderstorms across the mountains, then should gel into a line as they move east of the Blue Ridge. Convection Monday morning and early afternoon should remain spotty, but more coverage than what we had Friday and Saturday afternoon. By the evening, strong to severe storms across northern Virginia will advance south into the area. Damaging winds will be the primary threat Monday with large hail and flooding being secondary threats. Depending on the coverage of heavy rain today, a Flash Flood Watch may be needed for Monday into Monday night. PWAT values will be around 1.5-1.7 inches which is 100 percent above normal. In this moist environment, storms will not have to be very efficient to drop 1-2 inches of rain in a short amount of time, possibly more if they are slow moving. With the later arrival of the front Monday, highs will range in the mid 70s to lower 80s north of highway 460 to low to mid 80s south. Following the front Monday night, a weak wedge of high pressure will move over the region. With a moist easterly flow and isentropic lift, light rain/drizzle/fog will remain over the area into the day Tuesday. Models are eroding the wedge across the mountains by the afternoon, but hang on to it over the piedmont until late in the afternoon. The wedge should completely erode overnight Tuesday as a surface cold front tracks over the region. With the wedge in play Tuesday, high temperatures will run cooler than normal, ranging in the 70s. && .LONG TERM /THURSDAY THROUGH SATURDAY/... As of 1230 PM EDT Saturday... On Wednesday, despite the cold frontal passage, the consensus of solutions offers a forecast that will be have precipitation limited to primarily western parts of the region during the morning. The concern is northwest flow behind the front will help to mitigate downstream convection across the Piedmont by the afternoon. Wednesday night through the remainder of the forecast period, there is notable disagreement between the operational GFS and European solutions, especially from Friday night and onward. Both of these become out of phase in their trough/ridge configurations over eastern CONUS. What matches somewhat well is a general troughiness across the west coast and to a lesser degree the location of ridging across central CONUS. The big difference is the width of this ridge by the end of the forecast period is much broader for the European solution, thus the aforementioned ridge/trough differences over the eastern CONUS. Wednesday night into Thursday night guidance is starting to deviate, but is close enough for there to be reasonable confidence in a dry forecast Wednesday night and perhaps the first half of the day Thursday as the front sags to our south and shortwave ridge of high pressure briefly is across the region. Late Thursday afternoon through Friday, guidance offers a solution of shortwave trough moving through the area. However, timing differs, and the GFS starts its trend toward a much wetter solution as it offers not only the passing of the shortwave trough, but also a solution of baroclinic zone starting to become stationary over the region in response to increasing troughiness from the Great Lakes to New England. The European solution is quicker, and less wet, with this disturbance because in its solution the disturbance is a quick southerly moving system on the east side of a building upper ridge. Our forecast from Thursday night through Saturday will represent a blend of models with its output leaning toward the wetter and cooler operational GFS solution. Temperatures during this portion of the forecast are expected to be about five degrees above normal Wednesday into Thursday then five degree below normal Friday into Saturday. Confidence in the Tuesday night through Thursday part of the forecast is moderate. Confidence in the Thursday night through Saturday part of the forecast is low. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 130 PM EDT Sunday... Little has changed with the synoptic conditions since this time yesterday. Scattered storms firing up this afternoon from along and west of the Blue Ridge will shift east around 10-15 kts through the afternoon. Will see storms close enough to all airports to have VCTS in, and trying to time storms per high-res models and radar trends so added tempo groups thinking each airport can expect a thunderstorm. Confidence medium on this. Front starts to sag southeast tonight, but we are likely to see some low clouds and/or fog at places that had rain. Confidence higher at BCB/LWB for getting LIFR fog by morning, but MVFR at other sites, though BLF could also see some lower cigs. Medium confidence on this, but high confidence on sub-VFR after 09z tonight. Going to see fog/low clouds lift Monday morning with convection arriving toward the end of the taf period, but leaving it out as more widespread looks likely after 18z Monday. Winds will remain light and variable through most of the period, perhaps favoring light southwest during the daytime hours, except erratic around TSRA. .Extended Aviation Discussion... A cold front will move across the Ohio Valley and into the Mid- Atlantic region into Monday and Tuesday. This front will likely stall or drift only slightly further south into early next week, keeping unsettled conditions in place for several days. Model guidance suggests high likelihood for showers and thunderstorms with potential for sub-VFR ceilings and visibilities with the greater coverage shifting into southern sections by Tuesday. Overall, Monday afternoon still appears to be the day with the most widespread coverage of convection and associated aviation difficulties. There will still be periods of MVFR and even VFR. Conditions are expected to improve a bit through the later half of next week, but still a threat of at least diurnally driven showers/thunderstorms with daily potential for late night fog/low clouds each day during the period. && .HYDROLOGY... As of 445 AM EDT Sunday... WPC has advertised a marginal threat for excessive rainfall today and Tuesday, with a marginal to slight threat in southeast WV and far western VA for Monday. Locally heavy rainfall and a flood/flash flood threat will continue on an isolated to scattered basis today and tonight as scattered thunderstorms develop mainly across the northern parts of the forecast area, generally north of U.S. 460, with less coverage further south. However, with PWATS about 100% of normal hovering around 1.50, locally heavy rain will remain possible in any thunderstorms. Upper level steering currents are chaotic and weak, so storms will drift only slowly. Rainfall amounts of 2-3 inches in an hour or so are not out of the question, which will result in localized flooding or flash flooding. FFG values are relatively low, especially in the north and west with values ranging from Monday will bring a greater threat of flooding to the forecast area as the aforementioned frontal system drifts closer to the area from the north. The greatest threat for flash flooding will be across southeast WV and far southwest/western VA, mainly west/north of a line from Hot Springs to Blacksburg, to Wytheville, to Bluefield. With 3hr FFG values of around an inch north to 3 inches south, 2-3 in/hr rainfall rates will definitely cause at least localized problems as well as sharp rises on small creeks and streams with such basins. LWX has issued a Flash Flood Watch (FFA) for the northern parts of VA today, but no other neighboring offices have at this point. Feel that activity will be too scattered today to warrant a general FFA. However, Monday could bring a greater threat for flooding as the front and associated convection drifts closer to or into the northern parts of the CWA by evening. An FFA may need to be issued for Monday and Monday Night with later forecasts, especially the western and mountainous parts of the CWA. Will continue to highlight the potential flood/flash flood threat in the HWO, eHWO, and DSS email. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
