DISCUSSION
AT THIS HOUR, MID TO UPPER LEVEL CLOUDS CONTINUE TO STREAM IN OUT
OF THE SOUTHEAST FROM EXISTING CONVECTION THAT DEVELOPED EARLIER
THIS EVENING OVER SONORA, MEXICO. THERE IS CURRENTLY A MESOSCALE
CONVECTIVE SYSTEM (MCS) LOCATED OVER THE NORTHERN PORTION OF THE
GULF OF CALIFORNIA, WHICH DOES HAVE THE POSSIBILITY OF PROVIDING
THE SAN DIEGO AREA WITH SOME SHOWERS DURING THE MORNING HOURS AS
IT MOVES OVERHEAD, AS LONG AS IT IS ABLE TO HOLD TOGETHER AS IT
CROSSES OVER THE BAJA SPINE. OTHERWISE, THERE WILL LIKELY BE JUST
A LOT OF MID TO HIGH LEVEL CLOUDS, WITH SOME VIRGA (RAIN
EVAPORATING BEFORE IT REACHES THE SURFACE). WINDS BOTH AT THE
SURFACE AND ALOFT WILL GENERALLY BE OUT OF THE SOUTH TO SOUTHWEST
AND RH VALUES WILL CONTINUE TO INCREASE WITH GOOD RECOVERIES
OVERNIGHT AS LOW LEVEL MOISTURE INCREASES.
