.AVIATION /00Z TUESDAY THROUGH SATURDAY/... Expect occasional gusts around 35 to 45 knots to continue through this evening into the early portion of the overnight. A few gusts to 50 kt are possible, especially for KMRB. Winds will diminish a little, but still remain somewhat gusty after 6z through most of Tuesday before further diminishing late Tuesday afternoon into Tuesday night. Did bump winds down around 5 to 8 knots tonight, but pick them right back up Tuesday morning. Do think the magnitude will be less Tuesday, but still probably gusting in the mid 30s knots. Will watch a couple disturbance. The first one will pass through late Tuesday night into early Wednesday. A few flurries or light snow cannot be ruled out, but confidence is very low at this time. A stronger disturbance may bring a little light snow late Wednesday night into Thursday. Will continue to monitor both of these systems. Behind an earlier cold front, a blustery northwesterly wind is expected on Thursday with afternoon gusts to around 20 to 25 knots. A few mountain snow showers could spillover toward KMRB, but confidence is low at this time. Expect VFR conditions for Thursday into Friday with wind fields gradually decreasing in time as high pressure approaches from the west. A few showers could graze KCHO on Saturday, but chances are on the lower side. VFR conditions are likely to prevail into the weekend. Winds will be somewhat variable on Friday before shifting to north-northwesterly on Saturday. AVIATION...BJL/BRO/DHOF/CJL Update as of: 813 PM EST Mon Dec 29 2025
