.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... VFR conditions are likely at all terminals through Saturday afternoon as high pressure gradually departs off the Atlantic coast. Winds are somewhat variable before turning more southwesterly on Saturday. Given decent vertical mixing, gusts up to 20 knots are possible, especially during the afternoon hours. Shower and thunderstorm chances increase on Saturday evening, with KMRB seeing the most likely chance for restrictions. Further south, high-resolution models depict a weakening trend into the night. Winds shift to northwesterly behind the front midday Sunday with any convective chances mainly near KCHO. High pressure building to the north will yield mainly north to northeasterly winds into Sunday with continued VFR conditions. VFR conditions are expected Monday and Tuesday with surface high pressure building over the terminals. Winds remain light blowing 5 to 10 knots each day with northeast winds on Monday shifting to south on Tuesday. AVIATION...AVS/BRO/DHOF Update as of: 802 PM EDT Fri Jun 5 2026
