580 FXUS61 KRNK 142331 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 631 PM EST Fri Nov 14 2025 .SYNOPSIS... A surface low tracking through the Great Lakes region on Saturday and Sunday may bring some light rain showers to the mountains; however, chances remain low, with the best chances remaining across SE West Virginia. Dry and windy conditions in the wake of the low may increase fire weather concerns once again on Sunday. Rain chances return Tuesday and Wednesday as another system pushes through the region. && .NEAR TERM /THROUGH SATURDAY/... As of 630 PM EST Friday... Key Message: 1) Warm and dry under broad high pressure. A few isolated rain showers have developed in parts of central and eastern WV so far this evening, but otherwise the weather remains quiet. Some rain showers look to reach parts of SE WV late tonight, but are not expected to make it much farther past the WV/VA state line. Clouds will continue to increase through the overnight, with moisture advection increasing over the area. Tomorrow will be even warmer than recent days, with gusty winds through the day. Previous discussion below... As of 200 PM EST Friday... A warm front lifting north through northern West Virginia and Pennsylvania overnight and into Saturday morning will bring chances for some light upslope showers to portions of SE West Virginia through the early morning hours Saturday. Outside of SE West Virginia, the rest of the area should remain dry on Saturday. This aforementioned warm front will be in association with a surface low that is expected to track through the northern Great Lakes region on Saturday. Ahead of this low, a tight pressure gradient accompanied by a southwest 40-50 knot 850mb LLJ will move over the region Saturday afternoon. These combined factors look to slowly increase winds and wind gusts throughout the day on Saturday areawide, with Mountain locations likely seeing the highest gusts. Towards the evening hours on Saturday, a cold front is expected to quickly approach from the west, but does not look to pass through the area until Sunday. Overall, with the region being in the warm sector of this surface low on Saturday, temperatures will climb to above average values for this time of the year. Highs will generally climb into the low 70s east of the Blue Ridge, and low to mid 60s west of the Blue Ridge. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... As of 200 PM EST Friday... Key Messages: 1) Warm Sunday before cold front arrives to cool things down and bring a chance of precipitation. 2) Windy conditions following front raises fire weather concern. Model guidance continues to show a surface low pressure system making its way across the Great Lakes and into northern New England. This system will bring in a cold front Sunday and a chance of precipitation for the western portion of the forecast area. Things will be a bit warm for this time of year until the cooler weather after the front moves in. Sunday afternoon high temperatures will likely be in the mid-50s to upper 60s, potentially reaching 70F in the Piedmont/Foothills. Dew points will also be much higher than normal for this time of year with values in the 40s and 50s. Rain showers will be limited to the western mountain counties, and accumulations only up to 0.10" are expected. After the front passes, cooler and drier air returns. The weather becomes calm and benign as a surface high pressure system moves into the Mid-Atlantic from the Canadian Great Plains. Before the high pressure gets here, however, winds from the cold front will pick up considerably. Sustained winds are likely to be between 10-15 mph with gusts of 25-30 mph with higher values at ridgetops due to an impressive low level jet at 850mb with winds of 40-50 mph. Model guidance suggests relative humidity values between 20-30% Sunday afternoon and in the teens Monday afternoon. With high winds, lack of rain, and an influx of dry air, conditions are favorable for rapid fire spread. This will be monitored in the coming days for impacts and updates. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 200 PM EST Friday... Key Message: 1) Additional rain chance later this week from low pressure system. 2) Higher than normal temperatures for the rest of the week. Models are having considerable agreement on what to expect for the rest of the week. A low pressure system to our west will provide an extended warm front stretching eastward towards the east coast. This front will likely move north enough to provide a chance of precipitation for the region. Precipitation is possible as early as Tuesday morning for the entire area but is higher west of the Blue Ridge. Early morning freezing temperatures may result in some snow mixing in with the rain, especially in West Virginia, but the dominant precipitation type is forecast to be rain. A large surface high pressure system just to our north will determine how far north the warm front goes. It very well could block most the low pressure system`s path so this system will be monitored in the coming days. There is a brief quiet period before another surface low develops off the Rockies and pushes a cold front towards the region. This frontal system will likely give another round of precipitation but the timing and impacts are uncertain as of now. Otherwise, a mid- level ridge builds over Florida with its ridge axis stretching into the Mid-Atlantic. There will be a warming trend where temperatures may be a little higher than normal for this time of year with highs in the mid-50s to mid-60s. && .AVIATION /23Z FRIDAY THROUGH WEDNESDAY/... As of 620 PM EST Friday... VFR conditions prevail across the area and will continue for much of the current TAF period for most terminals. However, ceilings will lower to MVFR for KLWB and KBLF after 06Z Saturday, as a front approaches the area from the west, and could also bring a few hours of rain showers through about 14Z or so. However, the MVFR ceilings will continue off and on through much of the TAF period for those two WV terminals. Visibility restrictions are not anticipated with any rain through the TAF period. Southwesterly to westerly winds between 5 to 10 knots will continue through the remainder of the evening, but will increase once again after 06Z, and gusts between 15 to 20 knots is likely for all terminals along and west of the Blue Ridge by 12Z Saturday. Gusts will continue to increase through the TAF period, with even KLYH and KDAN seeing gusts between 15 to 20 knots after 20Z Saturday. Some low level westerly wind shear up to 35 knots is possible for KBCB and KLWB as a low level jet strengthens across the mountains between 06Z and 12Z, and possibly KROA, but confidence is too low to include in the KROA TAF at this time. .EXTENDED AVIATION OUTLOOK... Conditions should be mainly VFR through Wednesday, outside any mountain rain showers that may bring local sub-VFR cigs to mountain TAF sites. Gusty winds continue through Monday, with the strongest gusts expected on Sunday. && .FIRE WEATHER... As of 100 PM EST Friday... Key Message: 1) Gusty conditions return Saturday, but more moisture increases RH areawide. 2) Gusty and dry conditions return on Sunday, with fire weather concerns returning. Temperatures will trend warmer into the upcoming weekend. Warmest readings are forecast along and east of the Blue Ridge where readings will return to above normal. Caveat, there will be some clouds and showers around and a bit higher Rh, so there is a trade off. Winds will increase again over the weekend, so not totally out of the woods with respect to wind either. Dry air looks to return on Sunday, with windy conditions lingering. This may increase fire weather concerns across the area once again, with possible fire danger statements needing to be issued for portions of the area. In a nutshell, several more days of heightened awareness. As for rain potential...little or no measurable rain is expected until middle of next week. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None.
