NAM shows the most aggressive return of moisture and even suggests a ceiling, but most other guidance including SREF members are not as aggressive. Will go with SCT030 starting at 06z for all three sites to suggest a layer might be on the way. All guidance continued to stream moisture toward the sites, and agree that moisture is on the way, and ceilings would be expected (if not in this forecast window, then some time afterwards. Winds should be light throughout. && .MRX WATCHES/WARNINGS/ADVISORIES... NC...None. TN...None. VA...None. && $$ GM
