.AVIATION /19Z THURSDAY THROUGH TUESDAY/... VFR conditions are expected through early this evening, though mid and high level clouds will increase. Winds have already begun to increase out of the south with 10 to 15 knot gusts being reported at many of the terminals. This will continue through early this evening. Sub-VFR CIGs are expected to develop overnight as a warm front approaches from the south, but the onset of lower CIGs could be delayed by antecedent dry air. Rain looks to overspread the region from SW to NE between 03-06z. The main push of rain will likely exit between 21-00z Friday afternoon/evening, but with additional shower activity possible as the system's cold front moves through. LLWS is expected after about 03z tonight, possibly lingering as late as 18z Friday depending on the evolution of surface winds and whether or not mixing takes place as a warm front lifts through. Some guidance (notably the 00z HRRR) has a localized ribbon of briefly higher wind gusts as the warm front lifts through Friday. VFR conditions look to return late Friday night and persist through Saturday as winds shift around to the northwest after the low passes. Sub-VFR ceilings are possible Sunday as a warm front lifts toward the area. Also will see some gusty southerly winds up to 25 knots, especially west of the Blue Ridge. VFR conditions should return Monday and Tuesday. Expect relatively light WNW winds Monday, turning SW by Tuesday. Winds will only be around 10 to 15 knots during this time.
