.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... VFR conditions are forecast to persist through Saturday. The main aviation impact is going to be from strong wind gusts through the day today. Peak gusts around 30-35 knots expected into this afternoon. Winds decrease this evening into tonight. Light winds expected for Saturday as high pressure moves overhead and then offshore Saturday night. A low pressure system may bring a wintry mix in the west on Sunday morning, but will mostly favor rain farther east. The best shot at some wintry precipitation would be at MRB during the first half of the day. Elsewhere, likely only going to see a cold rain. This expected precipitation through the day Sunday will lead to reductions in ceilings and visibility. VFR conditions are expected Monday through Monday night, then sub- VFR conditions are likely Tuesday as an area of low pressure moves east of the area. A wintry mix is possible at all terminals, with snow and freezing rain Tuesday morning, before transitioning to rain in the afternoon. Additional restrictions from low clouds and reduced visibility are likely through Tuesday night. AVIATION...CJL/KRR Update as of: 139 PM EST Fri Nov 28 2025
