(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 krnk 130508 afdrnk area forecast discussion national weather service blacksburg va 1208 am est Tue nov 13 2018 Synopsis Low pressure from the gulf will track over the region tonight, reaching the new england coast Tuesday. Meanwhile, a cold front entering the ohio valley will move east and stall along the coast Tuesday night. Low pressure will develop along the front over the southeast united states Wednesday night and track through the mid atlantic region Thursday. Near term through Tuesday As of midnight est Tuesday... heaviest of the rain as moved into central eastern nc va with lingering drizzle mist fog across the remainder of the cwa. Flood warning has been issued for the dan river per 2+ inches of rain. Flood advisories are also ongoing for parts of the va nc piedmont..Streams creeks either bankful or into minor flood, some road closures noted. A wedge of cool air remains over the area. Readings should remain steady or rise a few degrees overnight once the rain tapers. A few locations are hovering around 32, including blacksburg, but no ice has been reported. The surface low which has resulted in the widespread rain is forecast to track northeast and off the DELMARVA coast Tuesday morning. A weak cold front will then slide across the region, bring additional light rain showers to the area. Rain will taper off from west to east in the afternoon as the front moves to the coast. Overcast skies will likely remain through the day with high temperatures recovering into the mid to upper 40s across the mountains and lower 50s east. Short term Tuesday night through Thursday night As of 245 pm est Monday... Tuesday evening the far southwest portion of the area will be receiving the tail end of the exiting line of showers associated with the departing cold front. Western greenbrier county will start to experience northwest upslope flow, residual moisture and falling temperatures to yield some isolated snow showers. Both regions of light precipitation are expected to end by midnight. Dry high pressure will make a brief visit to the area Wednesday morning. By the afternoon, light precipitation will start to overspread this high pressure from the south. This precipitation, in the form of light rain, will primarily only impact the northern mountains of north carolina through sunset. Wednesday night into Thursday, precipitation will continue to overspread the area on the eastern flanks of an area of low pressure moving eastward through the mid-mississippi river valley. A strong, deep, southeast fetch of moisture off the atlantic will develop. This moisture will only help to enhance the nose of high pressure east of the crest of the blue ridge, helping to keep surface temperatures on the cool to cold side, all while bringing a nose of warmer air over the region not too far off the surface. The result will be about an 18 hour period where a decent portion of the forecast area will be receiving freezing rain to at least some accretion. Highest amounts are expected to be along and near the crest of the blue ridge thanks to enhanced precipitation totals here where the effect of a southeast upslope flow will maximize precipitation totals. Given how far out in time this event still is, will be using a fairly conservative 33% ice versus wpc QPF totals. Even doing this results in some storm total ice amounts at or a little above the quarter-inch threshold in the aforementioned favored areas, with at least a few hundredths of an inch for a vast majority of the forecast area save parts of southside virginia and north central north carolina, and far southwest virginia towards richlands. This trend upward in ice totals matches well with the trend offered by wpc as reflected in their most recent 3-day ice accretion totals. While we are forecasting for the early part of Thursday rain versus freezing rain, sleet could also be falling over parts of the area currently forecast for freezing rain. To keep the forecast simple that far out, we try not to offer more than one winter weather type at a time in the forecast, but either freezing or snow. With the warm nose in place, freezing rain, where warranted, is the better choice of the two. However, as we get closer to the date in question, and sleet looks more probable where freezing rain currently is forecast, this alteration would lower the currently forecast ice accretion totals. By Thursday afternoon, the entire region looks warm enough for plain rain, albeit a cold rain. Thursday night, the parent upper low is expected to be moving along the mason dixon line, bring its associated trough axis and cold front through our region. This transition will shunt the warm nose to our east as cold air advection streams into the area on progressively gusty northwest winds. This will result in a transition to scattered rain snow showers across mainly western sections of the area. During this portion of the forecast low temperatures will average around normal. However, high temperatures will be about 10 degrees below normal on Wednesday, and about 15-20 degrees below normal. |
Forecast confidence is moderate on the general transition of the weather patterns during this portion of the forecast. However, confidence regarding the specific precipitation types and amounts Wednesday night into early Thursday are still in question and likely will flucuation between now and then. What is of high confidence is some type of wintry mix other than just rain versus snow is expected during this time period, raising the flag for the strong potential for a winter weather headline for portions of the area. Long term Friday through Monday As of 1230 pm est Monday... Friday morning an upper low will be making headway eastward through the upper ohio river valley with its associated trough axis extending southward into a portion of our forecast area. A timing challenge within the models exists to pinpoint just where this axis will be at the start of the day. However, the general trend of the day will be for any lingering precipitation in the east from the Thursday Thursday night system to be exiting the region, or to dissipate thanks to increasing northwest, downsloping, winds across the eastern parts of the area. Across the west, these same gusty northwest winds will allow for a period of upslope scattered snow rain showers across portions of southeast west virginia. Heading into and through the weekend, a general northwest flow pattern will continue across the area, but but with notably weaker speeds. Very isolated lingering rain snow showers will be possible across parts of southeast west virginia Friday night through Sunday. Sunday night into Monday models vary as to the degree which a cold front will impact our region. Our latest forecast will reflect a consensus of the guidance which yields isolated rain snow showers from roughly the blue ridge and points west Sunday night and isolated rain showers across the southeastern sections of the area on Monday. Temperatures during this portion of the forecast are not expected to show a lot of variation, although there will be a slightly trend lower by the second half of the weekend post-cold front. Readings on average will be just a few degrees below normal. Forecast confidence is highest on Friday, at moderate confidence, and trends downhill heading into Monday. Aviation 06z Tuesday through Saturday As of midnight est Tuesday... expect poor flight conditions through early Tuesday morning due to sub-vfr ceilings visbys, mountain obstruction and areas of wind shear above wedge inversion around 3000 feet. Steady, at times light rain drizzle mist producing visbys commonly in the 2-5 sm range will continue across the forecast area with the heaviest rains occurring east of kdan. As initial frontal wave low moves northeast, this rain should begin to decrease to mainly drizzle from west to east through the overnight, though fog mist and low ceilings (ifr to lifr at times) likely to persist Tuesday morning. Winds mainly northeast at 3-8 kts, though increasing southerly low- level jet and directional shear through the 925-700 mb level indicates potential for wind shear in the piedmont foothills for the overnight. Should see some improvement Tuesday afternoon into Tuesday night as winds become northwest. Forecast confidence is high for poor flight conditions and lower end flight categories. Extended discussion... look for ceilings to trendVFR from the blue ridge eastward thanks to downsloping winds for Tuesday night into early Wednesday, but lingering sub-vfr ceilings along with intermittent upslope snow showers possible between kblf-klwb. Another area of low pressure develops along the front on Wednesday and brings deep moisture back into the mid atlantic region later Wednesday into Thursday. Sub-vfr possible in rain and areas of wintry mix Wednesday night into early Thursday espcly across the mountains. This storm system is expected to exit the region by Friday with conditions returning toVFR with the exception of residual upslope snow showers on the western slopes of the central appalachians. Forecast confidence above average Tuesday and average Wednesday through Friday. Rnk watches warnings advisories Va... None. Nc... None. Wv... None. Synopsis... Rcs near term... Pm rcs short term...
