.AVIATION /02Z FRIDAY THROUGH TUESDAY/... Despite some improvements at times, flight conditions will remain IFR or LIFR straight through Friday morning due to low ceilings. Occasional rain can be expected throughout the evening hours, then there may be a bit of a dry slot for part of tonight. Drizzle could still occur at times, and it's possible fog could also worsen. Remnant convection from the Ohio Valley will move through late tonight into Friday morning. While it's unlikely any thunderstorms reach the TAF sites, there could be some briefly heavier rain rates. The rain will exit by midday Friday. However, low ceilings may persist into the afternoon, especially for the metro terminals, as the warm front may still not lift north. Overall winds will remain northeast to southeast at 10 kt or less. If the warm front lifts north, winds will shift to southerly before the cold front reaches the area during the late afternoon or evening. West winds will follow this front. Winds will also increase aloft with the frontal passage, so have introduced low-level shear groups at the KIAD, KDCA, and KBWI on Friday evening. VFR conditions with light west winds can be expected Saturday. Sub-VFR conditions appear likely on Sunday, regardless of the exact storm track that takes place with the area of low pressure sliding by to our south. The big question will be "how much snow?". It is still too early to tell if we get any snow, and how much, but the most likely time period for snow would start late Sunday evening and into Sunday night. At this point though, there is still a good chance for an all rain event as well, especially if the system develops too far offshore. In that scenario, we may not even see severe restrictions. With the level of uncertainty, this storm could cause restrictions through Monday as well, but right now would favor clearing by the afternoon.
