Waiting For Bit Of Rain

                                     

Pristine, clear skies in the view south from Kitt Peak this morning.

Down at bottom is current "Weather Story" from NWS at San Diego, where rains of 5 to 7 inches have already fallen over much of their forecast area. Very significant event underway for extreme Southern California as the 500 mb low this morning (below) remains over southern California.



Models continue to forecast the low to move south and eastward across Arizona tomorrow bringing us a chance of showers, and perhaps thunderstorms. Forecast above is from the 06 UTC WRF-GFS and is for radar echoes at noon tomorrow (Saturday the 11th).


Total QPF forecast from the same WRF run above through noon on Easter Sunday. Plumes below for QPF from the SPC plume viewer. Event continues to be forecast to occur tomorrow afternoon and continue into the night. Forecast amounts for southeast Arizona remain light - about a tenth or so posible at airport.
