First Day Of Storm



Heavy cloud cover over Catalinas at about 7:00 am MST on Thanksgiving morning.


Rainfall ending at 7:00 am for the storm so far (above from MesoWest). Amounts over metro area were generally light - less than 0.20" (here at house there was 0.06"). However, over Cochise and parts of Santa Cruz Counties amounts have been very heavy - many sites recording over two inches and several over three inches. San Pedro flow at Palominas, AZ (southeast of Sierra Vista on Highway 92), shown below, is over 7,000 CFS. Art Douglas sent this graphic, and also reports just less than three inches of rain at his place this morning.



Analysis for 500 mb this morning (above from NCAR RAP) shows that closed low is centered along the northern California coast. System forecast to move eastward slowly - GFS forecast below is valid at 5:00 pm MST tomorrow afternoon.

At bottom is precipitation forecast through 5:00 pm tomorrow, from the 06 UTC run of the WRF-GFS at Atmo. The GEFS system forecasts that most of this fall on the 29th, with just light showers around the metro today.

Hope all who visit have a great Thanksgiving Holiday.
