324 FXUS61 KRNK 170702 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 202 AM EST Mon Nov 17 2025 .SYNOPSIS... Clear and dry conditions to continue through tonight. Increasing clouds and chances of showers arrive on Tuesday from a quick moving disturbance. Unsettled weather returns again for the end of the weak and into the weekend, bringing a chance of rain Friday and Saturday. && .NEAR TERM /THROUGH TONIGHT/... As of 115 AM EST Monday... Key Messages: 1) Dry conditions continue. 2) Fire weather concerns again today across most of the region. Northwest flow behind a departing broad upper trough will continue to bring breezy conditions through this afternoon. Gusts still likely into the 20 mph range. High pressure will settle overhead tonight and winds will finally relax. The arriving airmass will be extremely dry with dew points falling into the mid to lower teens today. This very dry airmass, combined with continued winds in the 20 mph range will result in another day of increased fire concerns across much of the area. Highs today will be a bit cooler, but still may see upper 50s to lower 60s east of the mountains. Higher elevations remain on the cooler side in the mid 40s to lower 50s. && .SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... As of 130 AM EST Monday... Key Messages: 1. Chances for rain Tuesday into Wednesday, and again late Thursday. 2. Cooler temperatures for Tuesday, but above normal again by Wednesday. A closed upper low develops in the northern Plains, eventually opening into a wave as it reaches the Mid Atlantic late Tuesday into Wednesday. Broad ridging will strengthen over the Gulf and looks to remain situated there through much of the week after Tuesday. At the surface, a frontal system forms over the central US, with the warm front progged to lift northward over the area Tuesday into Wednesday, but not much forward progression, and appears to stall over the region. However, precipitation looks to be limited, more showery in nature than a prolonged rain. Showers will reach the western counties as early Tuesday afternoon and then continue through the overnight period, with showers lingering into Wednesday morning. At this time, amounts look to be highest in the higher terrain of southeast WV, southwest VA and northwest NC, between 0.75" to 1.0" with a sharp gradient in QPF farther east, up to 0.25" or so by the New River and Roanoke Valleys, then around 0.10" in the Piedmont. Rain chances return again late Thursday, as another low pressure system forms in the central Plains, and very similarly, the warm front lifting north into the Ohio Valley. With the southeast ridge building by the midweek, expect temperatures to trend above normal for Wednesday and Thursday, in the mid to upper 60s, possibly touching 70 in the NC Piedmont. Lows will be warm, in the 40s and 50s. && .LONG TERM /FRIDAY THROUGH SUNDAY/... As of 130 AM EST Monday... Key Messages: 1. More rain chances, especially in the west, nearly each day. More widespread chances on Friday night into Saturday. 2. Above normal temperatures continue through the weekend. Cooler on Sunday. There is more uncertainty in the forecast for late in the work week and into the weekend. The 500mb pattern shows split flow over the western US, with an upper low forming over the desert southwest, and another heading into the Pacific northwest, while the eastern US remains under the influence of the southeast ridge, though a trough looks to dive south from Canada late in the week. By the start of the long term forecast period, models start to diverge significantly in the evolution of the upper level flow. Confidence is high that a frontal system will develop in the central US and track eastward, bringing a warm front into the Ohio Valley by Thursday/Friday, and then a cold front into the area Friday/Saturday, though the uncertainty lies in the timing of the frontal passages. That being said, widespread chances for rain for Friday, but the rain chances persist through the weekend, especially in the west. The trend of above normal temperatures will continue through the weekend, with highs in the mid to upper 60s in the west and low 70s in the east Friday and Saturday, but cooler for Sunday after the cold front exits the region, in the mid to upper 50s in the west and mid to upper 60s in the east. The warm lows will finally cool down and drop back into the 30s and 40s by Sunday night into Monday morning. The high temperatures departures peak Friday, between 10 to 15 degrees above normal, and the low temperature departures will be greatest Friday night/Saturday morning, between 20 to 25 degrees above normal. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... As of 130 AM EST Monday... VFR expected throughout the valid TAF period. Main concern continues to be wind, which will remain gusty through this evening. Gusts in the 20kt range, with some occasional gusts over 30kts at the higher elevations today. Winds will gradually decrease this evening and tonight as high pressure settles overhead. .EXTENDED AVIATION OUTLOOK... Some MVFR restrictions possible Tuesday night/Wednesday with a passing system bringing rainfall to the area. VFR conditions look to return for the latter half of the week. Unsettled weather returns again for the end of the week and sub-VFR could return to the region. && .FIRE WEATHER... As of 150 AM EST Monday... Key Message: 1) A heightened risk of fire danger continues through this afternoon. A very dry airmass has settled into the region. RH values this morning have recovered very little with max RH only into the 30 percent to low 40 percent range. Will see another quick drop in RH today as daytime temperatures rise into the 50s and low 60s and dew points fall into the teens. This will result in min RH values in the low 20 percent range across the mountains and upper teens east of the mountains. Although winds will be lighter today than yesterday, still could have gusts around 20 to 25mph for a couple hours during peak mixing in the afternoon. These winds, combined with very low RH, will result in an increased risk of adverse fire behavior. Outdoor burning is discouraged...any fire could quickly spread. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
