Widespread But Light Rains Lat Night


View from Kitt Peak looking south this morning shows fog in valleys to east and west, as well as a skinny Cb far to the south. Down at bottom is deer caught in fog from webcam near Summerhaven.


Rainfall last night across metro was generally about a tenth of an inch - heavier amounts occurred west to north of Catalinas - no reports of half an inch or more. Only 0.09" here at house between 6:00 and 09:00 pm MST. ALERT map above is for 24-h ending at 6:30 am. Flash density map for CGs (below from weather.graphics and Vaisala for 24-h ending at 5:45 am) indicates some thunderstorms from southern New Mexico west to around San Diego and south into Mexico - there were reports of thunder around the metro last evening.



Highest PW amounts have remained south of 30 degrees north, as per MIMIC TPW analysis for 5:00 am above.
