Additionally, the frontal passage will result in a wind shift to northwest winds. A powerful Arctic front crosses the area early Saturday morning. Light winds will rapidly increase from the northwest around daybreak Saturday, with gusts of 40-50 kt ensuing and lasting through the afternoon. A few gusts above 50kt are possible at times, but the majority will likely be in the mid to upper 40kt range. Winds begin to decrease in the late afternoon, but still gusting 30-35 kt into the evening. Once this weekend's low passes through, winds should be fairly benign for the early portion of next week. Winds will likely shift SE overnight on Monday, and generally stay at 5-10 knots until a potential Wednesday low increases gust potential. VFR conditions likely for Monday and Tuesday, although a southern pressure gradient may cause some lower CIGs Monday night at KMRB. AVIATION...AVS/KRR/SRT Update as of: 352 AM EST Fri Feb 6 2026
