...DRY CONDITIONS WITH LIGHT WINDS TODAY AND TONIGHT...

.DISCUSSION...
HIGH PRESSURE AT THE SURFACE AND ALOFT WILL PRODUCE DRY WEATHER TODAY
THROUGH TONIGHT. A WEAK SYSTEM FROM THE PACIFIC WILL MOVE ACROSS THE
AREA SUNDAY AND WEAKEN BUT WILL CAUSE INCREASING CLOUDS AND A CHANCE FOR
SHOWERS BY SUNDAY MORNING. A STRONGER SYSTEM MOVES IN MONDAY AND STARTS
ANOTHER SERIES OF WET AND COOL SYSTEMS FOR THE UPCOMING WEEK. TEMPERATURES
CONTINUE MUCH BELOW NORMAL WITH ABOVE NORMAL PRECIPITATION...SO THIS
AFTERNOON LOOKS TO BE THE BEST PERIOD FOR DRY WEATHER AND BURNING CONDITIONS.
