Latest Aviation Discussion:

.AVIATION /13Z SUNDAY THROUGH THURSDAY/... A coastal low tracking up the Mid-Atlantic coast through Monday night is going to produce steady sub-VFR conditions at all terminals. MVFR to IFR CIGs will be commonplace, though gusty winds should keep them in the MVFR category during the daytime (with CHO likely lifting there shortly). Then the ceilings will likely drop again tonight. Periodic showers and light rain moving across the area will drop visibility to 3-5SM, though there does appear to be considerable dry time today. Expect breezy conditions to peak this afternoon with gusts of 25-30 knots. Winds diminish slightly tonight, but still gusting around 20-25 knots. VFR conditions look to return sometime Tuesday morning to early afternoon as the coastal low finally moves away from the area. Northwest winds gust around 20 knots Tuesday afternoon. In the wake of a strong cold front, northwesterly winds will prevail on Wednesday and Thursday amidst VFR conditions. Afternoon gusts could near 20 to 25 knots at times before diminishing into the evening to overnight hours. AVIATION...ADS/BRO/KRR Update as of: 1009 AM EDT Sun Oct 12 2025
