&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

A VORT MAX ASSOCIATED WITH A SHORTWAVE TROUGH THAT MOVED THROUGH THE
AREA OVERNIGHT DEVELOPED A LAYER OF ALTOSTRATUS OVER THE AREA
OVERNIGHT. THIS BROUGHT SOME LIGHT SNOW FLURRIES TO THE MOUNTAINS
AND THERE WERE SOME REPORTS OVER THE LOWER ELEVATIONS IN THE SAN
DIEGO AREA AS WELL. THE VORT MAX CONTINUED TO DRIFT TO THE SOUTH
DURING THE MORNING WITH CLEARING TAKING PLACE FROM THE NORTH ACROSS
THE NORTHERN PORTION OF THE AREA...ORANGE COUNTY AND THE INLAND
EMPIRE AREA NORTHWARD.

12Z NAM AND GFS INDICATE THE SHORTWAVE TROUGH SHOULD MOVE OUT
RAPIDLY TODAY WITH CLEARING EXPECTED OVER MOST OF THE AREA BY
AFTERNOON. THE AIR MASS REMAINS VERY COLD AND THE CLOUDS HAVE
LIMITED ANY HEATING THIS MORNING. THIS SHOULD KEEP MAXIMUM
TEMPERATURES SUPPRESSED TODAY. THIS SHOULD RESULT IN ANOTHER VERY
COLD NIGHT ACROSS THE AREA TONIGHT. WILL UPGRADE THE FREEZE WATCH
FOR THE AREA TO A FREEZE WARNING WITH THE AFTERNOON PACKAGE. WILL
PROBABLY HAVE TO INCLUDE ORANGE COUNTY...MAINLY FOR THE INLAND AREAS
AND THE SAN DIEGO COUNTY COASTAL AREAS...MAINLY FOR THE LOW COASTAL
VALLEYS FROM DEL MAR NORTHWARD THAT COULD HAVE TEMPERATURES DOWN
INTO THE LOW 20S TONIGHT.

NAM AND GFS INDICATE ANOTHER SHORTWAVE TROUGH WILL SWING THROUGH
MONDAY AFTERNOON AND NIGHT. THIS COULD BRING ANOTHER SURGE OF COLD
AIR SOUTHWARD OVER THE AREA FOR MONDAY NIGHT ALONG WITH SOME GUSTY
WINDS BEHIND THIS SYSTEM.

12Z GFS INDICATES A THIRD SHORTWAVE WILL MOVE THROUGH LATER IN THE
WEEK...LATE WEDNESDAY INTO THURSDAY AND FRIDAY. GFS INDICATES THIS
THIRD SYSTEM MAY NOT BE QUITE AS COLD AS THE ONE THAT WENT THROUGH
LAST NIGHT AND THE ONE EXPECTED ON MONDAY SO THERE SHOULD BE SOME
TEMPERATURE RECOVERY DURING THE LATTER PART OF THE WEEK.

&&

.AVIATION...
ROTATION AROUND A WEAK LOW PRESSURE SYSTEM OFF THE COAST HAS BROUGHT
A MID LEVEL CLOUD DECK TO MUCH OF THE AREA WITH A FEW FLURRIES IN
THE MOUNTAINS. SKIES SHOULD CLEAR BY EARLY THIS AFTERNOON WITH CLEAR
SKIES AND VFR CONDITIONS EXPECTED THE REST OF TODAY AND TONIGHT
ACROSS THE WHOLE AREA WITH UNRESTRICTED VISIBILITIES. WINDS ARE
