Latest Aviation Discussion:
.AVIATION /06Z THURSDAY THROUGH MONDAY/... Prevailing VFR conditions are expected at all TAF sites through Saturday. There's a small chance for some patchy fog prior to daybreak today, with MRB and CHO standing the greatest chance for a brief period with fog. If any fog were to form, it would quickly burn off after daybreak. There's also a very small chance for a brief shower or storms late this afternoon or evening. MRB would have the greatest chance, followed by MTN and BWI, but chances are still to low to mention in the TAFs. Winds will become northwesterly after sunrise today, turn westerly toward the middle of the day, and then north to northwest just prior to midnight as a cold front moves through. Light northerly winds are expected tomorrow, with light southerly winds on Saturday. High pressure remains over the region over the weekend which will favor VFR conditions across the area terminals. Thunderstorm chances (20-30 percent) return by Monday which could lead to brief restrictions during the afternoon/evening hours. Winds should be out of the south through Monday with gusts increasing to around 10 knots each afternoon. AVIATION...KJP/BRO/CPB Update as of: 318 AM EDT Thu Jul 3 2025
