Looking Ahead To Thanksgiving

View of sunrise this morning - above, looking east from San Simon. At bottom is a post-midnight view of last night's partial eclipse (photo by A. James McCarthy).

Above shows GEFS plumes for temperature at the airport for next eight days. Warm temperatures continue, but with slight cooling for Thanksgiving and end of week. The plumes for QPF (below) indicate chances for light showers on Wednesday night into Thanksgiving morning.

The 06 UTC GFS forecast for 500 mb (above) shows a fairly strong, closed low south of Tucson at 11:00 am MST on Thanksgiving day. Forecast for 24 rainfall from same run (below) indicates some chance for measurable rain for 24 hours ending at 11:00 pm Thanksgiving night. If this forecast verifies, it will be the measurable rain here since September 30th!
