DISCUSSION
AN UPPER LEVEL RIDGE WILL SLOWLY PUSH OVER THE INTERMOUNTAIN WEST. THIS RIDGE
WILL HELP AID IN NOCTURNAL INVERSIONS FOR MUCH OF THIS WEEK. THIS INVERSION
WILL LEAD TO CALMER WINDS AND POSSIBLY POOR SMOKE DISPERSAL. PEAK WINDS ARE
EXPECTED TO HIT BETWEEN 1 AND 2PM AROUND 35 MPH FOR THE MED BOW FOREST AREA
AND THEN SLOWLY CALM DOWN AS THE SUN SETS. RH VALUES MAY DROP A LITTLE LOWER
THAN FORECASTED DUE TO THE DOWNSLOPING WESTERLY WINDS DURING THE DAY WITH
RECOVERY AROUND 60 TO 70 PERCENT AT NIGHT.
