FORECAST IS BASED ON IGNITION TIME OF 1200 PDT ON APRIL 03.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
HIGH PRESSURE WILL BUILD OVER THE REGION TODAY...CAUSING WARMING
AND DRYING AND LOWERING MARINE LAYER TO BELOW 1500 FEET MSL.
GENERAL WINDS ARE FAIRLY LIGHT SO EXPECT DIURNAL SLOPE WINDS TO
DOMINATE. MIGHT SEE A LAKE ELSINORE EFFECT THIS AFTERNOON WITH
WINDS REVERSING FROM UPSLOPE/EAST TO DOWNSLOPE/NORTHWEST.

FOR TONIGHT...DRIER THAN LAST SEVERAL NIGHTS DUE TO ABSENCE OF
MARINE LAYER. SHOULD SEE INCREASE IN CIRRUS CLOUDS WHICH MIGHT BE
THICK ENOUGH TO OFFSET RADIATIONAL COOLING.

FOR THURSDAY...MARINE LAYER DEEPENS BUT NOT EXPECTED TO REACH
BURN SITE ELEVATION UNTIL LATE IN DAY...EVEN SO LOWEST HUMIDITY
WILL BE UP FROM TODAY AND OCCUR DURING MORNING HOURS.
CIRRUS CLOUDS THICKENING AND LOWERING TO BECOME ALTO STRATUS...
POSSIBLY THICK ENOUGH TO SHADE FUELS AND REDUCE STRENGTH OF
UPSLOPE WINDS. SO EXPECT LIGHT AND VARIABLE WINDS AND POOR TRANSPORT
OF SMOKE DURING MORNING AND EARLY AFTERNOON HOURS.
