KEY MESSAGES:
- SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE THIS AFTERNOON AND
EVENING PRIMARILY IN NW MONTANA.
- A STRONG RIDGE BRINGS DRY CONDITIONS AND HIGH TEMPERATURES INTO
THE 70S AND 80S THROUGH THE NEXT WEEK.
- DRY AFTERNOONS WITH MINIMUM RELATIVE HUMIDITIES IN THE 20%
RANGE AND BELOW.
A PASSING DISTURBANCE WILL TRIGGER SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS, AGAIN, THIS AFTERNOON AND EVENING. THE HIGHEST
CHANCES REMAIN ACROSS NORTHWEST MONTANA, TAPERING OFF AS YOU HEAD
SOUTH TOWARD THE I-90 CORRIDOR. EXPECT BRIEF HEAVY RAIN AND
LOCALIZED GUSTY WINDS NEAR ANY STORMS, ALONGSIDE WIDESPREAD
AFTERNOON GUSTS OF 15-25 MPH.
STARTING FRIDAY, A BROAD RIDGE OF HIGH PRESSURE BUILDS ACROSS THE
WESTERN U.S. DOMINATING THE WEATHER PATTERN THROUGH THE NEXT WEEK.
THIS WILL BRING A PROLONGED PERIOD OF DRY, QUIET WEATHER WITH HIGH
TEMPERATURES CLIMBING INTO THE 70S AND 80S. AFTERNOON RELATIVE
HUMIDITIES WILL DRY OUT INTO THE 20 PERCENT RANGE AND BELOW. A
COUPLE OF VERY WEAK WAVES MAY BRUSH THE REGION ON SATURDAY AND
MONDAY, BUT IMPACTS WILL BE LIMITED TO SLIGHTLY BREEZIER WINDS AND
A MINIMAL (10 PERCENT) CHANCE OF A PASSING SHOWER.
AVIATION
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE
POSSIBLE THIS AFTERNOON AND EVENING. THIS ACTIVITY WILL PRIMARILY
FOCUS ACROSS NORTHWEST AND WEST-CENTRAL MONTANA, BETWEEN 07/2000Z
AND 08/0100Z WITH BRIEF MVFR CONDITIONS POSSIBLE DUE TO LOWERED
CEILINGS ALONG WITH SOME GUSTY OUTFLOW WINDS. OTHERWISE,
WIDESPREAD WEST-NORTHWEST WINDS WILL GUST 15-25 KTS AT MOST
TERMINALS THIS AFTERNOON BEFORE SUBSIDING THIS EVENING. NOTE FOR
KHRF: ACTIVE PRESCRIBED BURNING AND FUELS MANAGEMENT IN THE
VICINITY IS CREATING PERIODIC, LOCALIZED REDUCTIONS IN VISIBILITY
DUE TO SMOKE. NOTE FOR KSMN: SENSOR OBSERVATIONS ARE BACK ONLINE
AND REPORTING NORMALLY ONCE AGAIN.
