DISCUSSION
HIGH PRESSURE IS BUILDING OVER THE AREA THROUGH THE WEEK AND WEEKEND.
THIS HIGH PRESSURE WILL INCREASE DAYTIME THERMAL MIXING, LEADING TO GUSTIER AFTERNOONS.
WINDS WILL BE MOSTLY DIURNAL IN NATURE WITH TERRAIN-DRIVEN FLOW. EXPECT UPSLOPE/VALLEY
GUSTS IN THE AFTERNOON AND CALM DRAINING WINDS AT FLAME LEVEL EACH EVENING. THE BURN
SITE IS PREDICTED TO BE BELOW THE THERMAL BELT, THIS WILL KEEP NIGHTTIME RH RECOVERIES
HIGHER AROUND 80% OR SO.
A WEATHER PATTERN CHANGE IS FORECASTED FOR MONDAY WITH STRONGER WINDS MIXING DOWN TO THE
SURFACE AS THE UPPER-LEVEL RIDGE BEGINS TO BREAKDOWN. THE SW ASPECT OF THE BURN SITE COULD
LEAD TO SOME LOCALLY LIGHTER, MORE VARIABLE WIND SPEEDS THAN FORECASTED. EITHER WAY, EXPECT
A CHANGE OF WEATHER FOR THE BEGINNING OF NEXT WEEK.
