DISCUSSION
IDAHO (ZONES 102 AND 103): WARM AND DRY CONDITIONS PERSIST THROUGH
THURSDAY. TERRAIN-DRIVEN WINDS AND MODERATE DAYTIME RELATIVE HUMIDITY
WILL CONTINUE TODAY, WITH POOR TO MODERATE OVERNIGHT RECOVERIES ON MID-
SLOPES AND RIDGES. WINDS BEGIN TO INCREASE OUT OF THE SOUTH AND
SOUTHWEST BY THURSDAY AFTERNOON. A COLD FRONT ARRIVES MIDDAY FRIDAY,
BRINGING WIDESPREAD GUSTY WEST WINDS AND ELEVATING FIRE WEATHER CONCERNS
UNTIL THE RAIN ARRIVES DURING THE AFTERNOON FOR ACTIVE FIRES AND BURNS.
A CUTOFF LOW THIS WEEKEND WILL BRING A SIGNIFICANT CHANGE, FOCUSING
HIGH PROBABILITIES FOR WIDESPREAD WETTING RAIN ACROSS CLEARWATER COUNTY
ALONGSIDE MUCH COOLER TEMPERATURES.
NORTHWEST MT (ZONES 104 AND 105): UNSEASONABLY WARM AND DRY CONDITIONS
CONTINUE THROUGH THURSDAY WITH LOCALIZED SMOKE FROM PRESCRIBED BURNS.
OVERNIGHT RELATIVE HUMIDITY RECOVERIES WILL REMAIN MODERATE ALONG MID-
SLOPES. A COLD FRONT WILL INCREASE WEST WINDS FRIDAY INTO SATURDAY
MORNING. A CUTOFF LOW THIS WEEKEND WILL BRING WIDESPREAD WETTING RAIN
AND HIGH-ELEVATION MOUNTAIN SNOW ABOVE 6,000 FEET, INCLUDING 1 TO 2
INCHES OF ACCUMULATION IN GLACIER NATIONAL PARK.
WEST CENTRAL MT (ZONES 106, 107 AND 108): SUMMER-LIKE WARMTH AND DRY
CONDITIONS CONTINUE THROUGH THURSDAY WITH LOCALIZED SMOKE FROM
PRESCRIBED BURNS. OVERNIGHT RELATIVE HUMIDITY RECOVERIES WILL REMAIN
MODERATE ON RIDGES. A COLD FRONT CROSSES THE US-93 CORRIDOR NEAR 6 PM
MDT FRIDAY, PRODUCING STRONG WEST WINDS AHEAD OF AND BEHIND THAT FRONT THAT
WILL LINGER BUT BEGIN TO RELAX INTO SATURDAY. A COOLER WEEKEND FOLLOWS
WITH INCREASING SHOWER CHANCES TOWARD THE NORTH FOR FRIDAY NIGHT INTO
SATURDAY MORNING.
SOUTHWEST MT (ZONES 109, 110 AND 111): UNSEASONABLY WARM CONDITIONS
PERSIST THROUGH THURSDAY WITH ISOLATED, LOW-IMPACT SHOWERS THIS
AFTERNOON. OVERNIGHT MID-SLOPE RELATIVE HUMIDITY RECOVERIES WILL BE POOR
TO MODERATE. A STRONG COLD FRONT ARRIVES FRIDAY EVENING INTO SATURDAY
MORNING, BRINGING GUSTY WEST WINDS UP TO 45 MPH, PARTICULARLY IN ZONE
111, WHICH WILL ELEVATE FIRE WEATHER CONCERNS. A MUCH COOLER WEEKEND
FOLLOWS WITH VERY LOW TO NONEXISTENT CHANCES FOR WETTING RAIN COMPARED
TO AREAS FURTHER NORTH AND WEST.
