.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/... VFR conditions continue overnight as winds increase in the wake of a cold front. West/northwest winds start out light this evening before gradually increasing from west to east overnight. Low-level wind shear may also be possible late tonight. Winds gust 15 to 25 knots Wednesday morning across all terminals with the exception being KCHO where light winds are expected. Winds diminish Wednesday afternoon with light and variable winds expected overnight. VFR conditions continue throughout the day on Wednesday as surface high pressure builds overhead. Cloud cover increases Wednesday afternoon with precipitation returning to the forecast overnight Wednesday into Thursday. A wintry mix may bring sub-VFR conditions to the metro terminals with KCHO and KMRB expected to have rain. Restrictions are possible through Thursday morning as precipitation moves through the forecast area. Primary precipitation type will likely be rain with temperatures right at or above freezing, although a rain/snow can't be ruled out. Conditions improve Thursday night. Friday will see plenty of cloud cover along with a wintry mix, particularly north of I-66/U.S. 50. Lengthy restrictions are looking likely as wintry precipitation falls amidst the low ceilings. Some ceiling restrictions could continue into portions of Saturday with moisture overrunning a boundary over the Carolinas. By Sunday, rain overspreads the region ahead of a strong cold front. Thus, expect additional periods of sub-VFR conditions across the terminals. AVIATION...AVS/BRO/KJP Update as of: 837 PM EST Tue Dec 23 2025
