.DISCUSSION...

A COLD FRONT HAS MOVED PAST THE BURN SITE. RH VALUES HAVE INCREASED
INTO THE 30-40% RANGE AS OF 10 PM THIS EVENING. THESE RH VALUES WILL
CONTINUE TO INCREASE TONIGHT AS LOW LEVEL MOISTURE INCREASES.

THERE WILL BE A GOOD CHANCE OF WETTING THUNDERSTORMS TOMORROW AFTERNOON
AS A WEAK DISTURBANCE MOVES ACROSS THE REGION AND COMBINES WITH THE
LOW LEVEL MOISTURE WHICH WILL BE IN PLACE.

LOOKING AT THE FORECAST THROUGH 56 JULY AND 10 JULY...EXPECT SCATTERED
WET THUNDERSTORMS EACH AFTERNOON. WIND FLOW WILL BE DIURNAL IN NATURE
EACH DAY...THAT IS...UPSLOPE FLOW IN THE AFTERNOON AND WEAK DOWNSLOPE
AT NIGHT. EXPECT HIGHS GENERALLY IN THE LOWER 80S WITH POPS IN THE 30%
RANGE DURING THE AFTERNOONS. MINIMUM RH VALUES WILL GENERALLY BE AROUND
20 TO 30%,
