MVFR ceilings are expected through the day, with chances for showers increasing through the afternoon hours. Even a stray afternoon thunderstorm can't be ruled out. Ceilings are expected to drop again tonight, and may reach IFR, but confidence was still to low to introduce IFR at most terminals. Light rain is expected through much of the night, before conditions clear out just prior to daybreak on Wednesday. VFR conditions and westerly winds are expected on both Wednesday and Thursday. Canadian high pressure will likely bring VFR conditions Friday through Saturday. AVIATION...BJL/KJP Update as of: 408 AM EDT Tue Sep 29 2020
