DISCUSSION
ANOTHER WAVE OF AREA SHOWERS AND THUNDERSTORMS IS ANTICIPATED
TO PUSH INTO THE WEST DESERT REGION THIS EVENING, BRINGING A
CHANCE FOR SHOWERS OVER THE FIRE THROUGH AROUND MIDNIGHT. PASSING
STORMS MAY BRING GUSTY AND ERRATIC OUTFLOW WINDS, HOWEVER, IF NO
STORMS PASS NEARBY THEN FLOWS WILL BE GENERALLY LIGHT AND TERRAIN
DRIVEN. MOISTURE REMAINS IN PLACE THROUGH THE DAY TOMORROW,
BRINGING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS OVER THE WEST
DESERT. WHILE THERE IS A FAIRLY LOW CHANCE (20-30%) FOR STORMS TO
MOVE OVER THE FIRE, DISTANT STORMS MAY STILL PUSH OUTFLOWS IN
EXCESS OF 30 MPH OVER THE AREA AFTER ABOUT 1300 UNTIL AS LATE AS
2300. TEMPERATURES WILL INCREASE MARGINALLY WITH HUMIDITY ALSO DECREASING
MARGINALLY ON THURSDAY ALONGSIDE TERRAIN DRIVEN FLOWS (OUTSIDE OF ANY
OUTFLOWS).
