NATIONAL WEATHER SERVICE MISSOULA MT
242 PM MDT TUE JUL 23 2019
DISCUSSION
IDAHO: ANOTHER PLUME OF MONSOONAL MOISTURE HAS PUSHED INTO THE REGION
THIS AFTERNOON, FURTHER MOISTENING AN ALREADY SOUPY ATMOSPHERE.
ADDITIONAL SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS ALL DISTRICTS
THROUGH THE REMAINDER OF TODAY AND INTO TONIGHT. WHILE FREQUENT
LIGHTNING IS EXPECTED, HEAVY RAINFALL MAY ALSO OCCUR GIVEN AN ABUNDANCE
OF ATMOSPHERIC MOISTURE. A COLD FRONT PASSAGE ON WEDNESDAY WILL BRING
BREEZY WINDS, ESPECIALLY ACROSS THE RIDGE TOPS. A RETURN TO MORE NORMAL
TEMPERATURES AND SEASONABLY DRIER WEATHER IS EXPECTED STARTING THURSDAY
AND PERSISTING THROUGH EARLY NEXT WEEK.
MONTANA: RECENT DEVELOPMENT OF SOME THUNDERSTORMS ACROSS WESTERN
MONTANA WILL ONLY BECOME MORE WIDESPREAD ACROSS THE BITTEROOT, LOLO,
DEERLODGE AND BEAVERHEAD FORESTS THIS EVENING. THIS ACTIVITY WILL
ULTIMATELY TRACK NORTHEAST TONIGHT AND AFFECT ALL FORESTS BY EARLY
WEDNESDAY MORNING. FREQUENT LIGHTNING IS EXPECTED, BUT ALSO THE HIGH
LIKELIHOOD OF HEAVY RAINFALL WITH MANY OF THESE STORMS. A STRONG COLD
FRONT WILL PUSH ACROSS MONTANA ON WEDNESDAY WITH GUSTY WINDS EXPECTED
ACROSS ALL FORESTS, BUT ESPECIALLY NW MONTANA. GUSTS ON THE RIDGES AND
PEAKS COULD PUSH NEAR 50 MPH AT TIMES. THEREAFTER MORE SEASONABLY WARM
AND DRIER WEATHER IS EXPECTED TO TAKE HOLD ON THURSDAY AND CONTINUE
INTO AT LEAST EARLY NEXT WEEK.
