.DISCUSSION...

A DRIER WESTERLY FLOW WILL BE OVER THE FIRE AREA TODAY AND TONIGHT.
THE THREAT FOR THUNDERSTORMS IS MINIMAL. A WESTERLY PRESSURE GRADIENT
FEEDING INTO THE THERMAL TROUGH WELL TO THE EAST OF THE FIRE WILL
PROMOTE LIGHT WESTERLY WINDS DURING THE DAY AND ENHANCED DOWNVALLEY
DRAINAGE AT NIGHT THROUGH WEDNESDAY. CONTINUED DRY AND STABLE
CONDITIONS CAN BE EXPECTED FOR WEDNESDAY. THE STAGNANT SUMMER PATTERN
MAY PROMOTE A MID-SLOPE THERMAL BELT TONIGHT AND WEDNESDAY NIGHT
WHICH MAY HAMPER RH RECOVERIES. TEMPERATURES WILL REMAIN UNSEASONABLY
WARM THROUGH THE WEEK. NO SIGNIFICANT STORM SYSTEMS OR FRONTS ARE
EXPECTED THROUGH THE END OF THE WEEKEND. THE NEXT SMALL CHANCE OF
THUNDERSTORMS OVER OR NEAR THE FIRE AREA WILL BE FRIDAY AFTERNOON.
