.AVIATION /18Z TUESDAY THROUGH SUNDAY/... With the focus for convection shifting to the south, only KCHO has convective groups in the TAF for today. At this point, any activity has been lacking so will monitor trends during the next shift. Otherwise, winds remain on the lighter side with some restrictions possible heading into the overnight hours. Patchy fog could yield some MVFR conditions, particularly across the more western terminals. Wednesday is looking fairly active across the area with the potential for sub-VFR conditions at all TAF sites. There was enough of a signal to go with a prevailing -TSRA group at KDCA, KIAD, and KBWI between 20-00Z. A PROB30 group remains for the few hours before given the potential for earlier convective development. Otherwise, southerly winds increase through the day with possible gusts up to 15 knots. Like previous nights, patchy fog may develop. Convective chances decrease on Thursday, but cannot rule out brief restrictions as air mass thunderstorms pop up. Prevailing VFR conditions are expected on both Friday and Saturday. A thunderstorm could lead to brief restrictions either afternoon or evening. Winds will generally be out of the northwest on Friday, and out of the south on Saturday. AVIATION...BRO/KJP Update as of: 332 PM EDT Tue Jul 15 2025
