NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Dec 12, 3:34 AM EST, 21 minutes earlier.
Area Forecast Discussion National Weather Service Blacksburg VA 334 AM EST Mon Dec 12 2016 .SYNOPSIS... A weak cold front will slide east across the region today followed by high pressure overnight. Weak upper disturbances will slide south of the area Tuesday into Wednesday before a strong Arctic cold front arrives on Thursday. Very cold air on strong northwest winds will follow the front for the end of the week. && .NEAR TERM /THROUGH TONIGHT/... As of 230 AM EST Monday... Dampening shortwave trough will pass well to the north today with its associated weakening surface cold front spilling to the Blue Ridge by afternoon and east of the area late in the day. Swath of deeper moisture seen on water vapor to slide through the west early this morning, and across most of the area by mid morning before fading as support for lift fades while the low level flow turns westerly. This supports a period of categorical to likely pops over the area this morning followed by a quick exodus of deeper moisture/precip by early to mid afternoon per most short short term solutions. Given the ongoing very strong warm advection per the 50+ knot 850 mb jet, appears any threat for icing will end before daybreak in the far northwest valleys, while expecting winds on the ridges to diminish shortly as the speed max passes and rain starts to limit downward mixing. May still have some spotty rain lingering across the upslope western zones a bit longer this afternoon, otherwise expecting good drying from top down later on with low level downslope drying east, where may even see some sunny breaks per westerly flow. Should see temps continue to rise given mixing ahead of the front this morning before leveling off far west behind the boundary this afternoon. However will be quite a rebound from the last couple of days with highs perhaps well into the 50s east and near 50 west of the Blue Ridge. Very dry air aloft off latest guidance forecast soundings suggests a pop free overnight under weak high pressure, although likely to see some trapped low clouds west and perhaps high clouds elsewhere under the fast zonal flow aloft. Moisture may also start to deepen across the far southwest late tonight ahead of next weak impulse but slower trends support most rainfall holding off for now. Otherwise running with partly to mostly cloudy mountains and more clearing east. Lobe of cold air following the frontal passage will ooze into far northern sections late allowing for lows to fall into the 20s along the I-64 corridor with low/mid 30s elsewhere pending clouds. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY/... As of 300 PM EST Sunday... Surface high pressure over the Mid Atlantic states Tuesday morning then moves offshore Tuesday night. Low pressure tracks along the stalled front in the far southeast. This system passes through South Carolina late Wednesday. Confidence is low concerning how far north any precipitation will get Tuesday and Wednesday. GFS showing enough isentropic lift fora low probability of precipitation south of the Virginia/North Carolina border on Tuesday night and Wednesday. Models quite different in the amount of moisture in the area on Tuesday and Wednesday. But both the NAM ans GFS hold low level moisture in the far western upslope areas for much of Monday night. Using a blend of bias corrected MET/MAV guidance for temperatures through Tuesday night. Winds diminish on Monday night,with the valleys becoming light and variable as the high passes overhead Tuesday morning. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... As of 1230 PM EST Sunday... Large arctic high moves from the Northern Plains on Wednesday night to the Ohio Valley on Thursday night. Expecting strong cold air advection Wednesday night and Thursday. ECMWF takes 850 MB temperatures as low as -16 by Thursday night. This is two to three standard deviations below normal. Have lowered maximum temperatures on Thursday and lows for Thursday night. Will have a period of upslope snow showers on the western slopes of the mountains for Wednesday night, possibly until Thursday night when the center of the high moves closer and the upslope winds end. There is decent consensus in the long range models that troffing will be developing in the western United States on Friday and Saturday and that two distinct short wave will be moving through the trof, one moving through the Great Lakes on Saturday and the next coming out of the base of the trof in to the Mid Mississippi Valley Saturday night and Sunday. Temperatures warm significantly on Friday and Friday night as region gets into the warm sector of the approaching low and cold front. Overrunning precipitation on the north side of the warm front will reach the Mid Atlantic region late Friday. Stayed warmer than guidance for the lows Friday night. 00Z GEFS was slower bringing the deeper moisture along the cold front into the region than the ECMWF. A cold front will cross the eastern United States Saturday night followed by a 1040MB high with more polar air for Sunday. More snow showers/flurries are likely behind this front Saturday night and possibly Sunday in the mountains due to strong northwest winds. && .AVIATION /09Z MONDAY THROUGH FRIDAY/... As of 1130 PM EST Sunday... Keeping the terminals similar to previous forecast thinking lower ceilings will impact most sites as rain moves in from the west, while wedge out east keeps cigs around 1200-3000ft. Appears LWB may be close to freezing where fzra will occur a couple hours at the start of the taf period, then increasing temperatures will change it to all rain. Ceilings are expected to be in the LIFR/IFR range as we head toward early Monday morning, as the low levels continue to moisten up. Will be hard pressed to clear out the sub VFR cigs Monday as the winds behind the front may not pick up until late in the day. Aside from Roanoke, kept the rest of the tafs 3000ft or lower through the end of the taf period. Another issue this evening into Monday morning will be the two surges of high winds around 2-4kft AGL. With mainly light winds aside from BLF look for low level wind shear to be an issue. Extended aviation discussion... Most of the area will return to VFR by Monday evening. The exception may be areas between KBLF-KLWB where upslope flow may help some MVFR ceilings continue during this time period. High pressure will help conditions remain VFR for the vast majority of the region Tuesday. Wednesday is questionable. Latest guidance is not as pronounced on a system impacting our region. However, it may still be in close enough proximity for MVFR ceilings to overspread the area. Wednesday night into Thursday, another cold front is expected to move into and across the area. Latest model trends are painting a somewhat drier pictures. Precipitation and sub-VFR conditions may be limited to parts of southeast West Virginia. Northwest winds will be on the gusty side Thursday into Thursday night. VFR conditions are expected on Friday as the center of high pressure moves over the region. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
