.AVIATION /00Z SUNDAY THROUGH THURSDAY/... VFR conditions are virtually certain through 00Z Monday, with the only chance for sub-VFR conditions coming in the 09-13Z Sunday timeframe across our eastern terminals (IPT/MDT/LNS). At this time, restrictions continue to be most likely in the form of fog/low stratus given some potential for breaks in the high- level cloud deck and/or slower eastward progression of the cloud deck. HREF ensemble probabilities continue to outline highest chances (~20-30%) at IPT/LNS, with GLAMP also outlining ~10-20% probabilities of this scenario unfolding overnight. The main concern is that fog would have to contend with some low-level dry air based on RAP model soundings. Based on this, have continued to hold stout with VCFG mentions with lower-level scattered cloud decks at IPT in the timeframe where restrictions will be possible. Outlook... Mon-Tue...AM valley fog; otherwise, VFR prevails. Wed-Thu...Rain showers, especially in the PM hours on Wednesday and continuing into Thursday. Sub-VFR conditions become more likely in showers. &&
