.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/... A weak front is settling across the area this morning which will waver across the area through Friday. Wind direction will be changeable but generally less than 10 kt over the next 24 hours, shifting north behind the front, becoming southeast later today, then back to the east or northeast tonight into Thursday. VFR conditions will prevail through this evening. However, stratus is forecast to move onshore late tonight, most likely affecting the metro terminals. CHO and MRB may be closer to the edge. Have the highest confidence in MVFR to IFR conditions, although some guidance does indicate LIFR. Stratus will likely be a recurring issue Thursday and Friday nights as well, with higher IFR probabilities across all terminals. The main uncertainty is whether the stratus mixes out each afternoon or remains in place. Even if ceilings remain, there should be improvement in flight category. Patchy drizzle could also develop Thursday and Friday nights. Otherwise light NE to E winds are expected during this time. Sub-VFR ceilings and visibilities are likely Saturday and Sunday as an approaching cold front brings widespread showers and possible thunderstorms to the terminals. Southerly winds on Saturday gust 15 to 20 knots across all the terminals with the exception being KMRB where gusts near 25 knots are possible. Winds increase overnight into Sunday with SW winds gusting 25 to 30 knots. Winds shift to northwesterly behind the frontal passage, with gusts between 15 and 20 knots expected overnight.
