A number of forecasts and outlooks have indicated serious amounts of rainfall and snow for the Southwest during the coming week. The radar chart above indicates that the rainy week is already underway in southern, coastal California.

From the NWS at San Diego on Friday the 15th -
HYDROLOGIC OUTLOOK
1220 PM PST FRI JAN 15 2010
...EXTENDED PERIOD OF SIGNIFICANT RAIN AND MOUNTAIN SNOW NEXT WEEK
FOR SOUTHERN CALIFORNIA...
A STORMY PATTERN IS SETTING UP ACROSS THE EASTERN PACIFIC OCEAN THAT
WILL BRING PERIODS OF MODERATE TO HEAVY RAIN AND MOUNTAIN SNOW TO
SOUTHERN CALIFORNIA MOST OF NEXT WEEK AND POSSIBLY INTO THE
FOLLOWING WEEK.
BASED ON HISTORIC PATTERNS...THIS WEEK-LONG EVENT HAS THE POTENTIAL
TO GENERATE RAINFALL OF 5 TO 8 INCHES NEAR THE COAST...TO 20 OR
MORE INCHES ON THE COASTAL MOUNTAIN SLOPES. TYPICALLY WETTER
LOCATIONS ON THE COASTAL MOUNTAINS SLOPES COULD RECEIVE 30 OR MORE
INCHES OF RAINFALL. AT HIGHER ELEVATIONS IN THE SAN BERNARDINO
MOUNTAINS... MOSTLY ABOVE 6000 FEET...4 OR MORE FEET OF SNOWFALL IS
POSSIBLE.

Steve Mullen reports that a local weathercaster last evening called for
up to 1" of rainfall in Tucson on Tuesday and up to 1 3/4" on Friday
with snow amounts in the Catalinas up to 5 feet.
This afternoon's NWS forecast indicates POPs of 100% for Tuesday night
and Thursday night - the highest POPs out at 48-hours and beyond that
I can recall since I moved here.
Quite a change from the last 3 weeks of no weather - better clean the
crud out of my rain gauge!
