DISCUSSION
KEY MESSAGES:
- THUNDERSTORMS WILL BE A NEAR DAILY OCCURRENCE FOR LEMHI COUNTY,
ID AND SOUTHWEST MONTANA.
- GRADUAL WARMING AND DRYING TREND THROUGH THE WEEKEND.
THE TROUGH PATTERN WITH SOUTHWEST FLOW INTO THE REGION WILL
CONTINUE INTO EARLY NEXT WEEK, AND AS A RESULT, THUNDERSTORMS
REMAIN IN THE FORECAST THROUGH NEXT WEEK. THE AFFECTED REGION WILL
REMAIN FAIRLY CONSISTENT AS WELL WITH A FOCUS IN THE BITTERROOT
AND EASTWARD SOUTH OF HIGHWAY 12. THE FLASH FLOOD RISK IS EXPECTED
TO DIMINISH EACH DAY AS A LITTLE MORE MOISTURE GETS WORKED OUT OF
THE SYSTEM.
EVEN WITH THE TROUGH OVER THE REGION FOR THE NEXT WEEK, WE EXPECT
A GRADUAL WARMING AND DRYING TREND. THAT IS BECAUSE THE TROUGH
WILL TREND WEAKER WITH TIME. BY THIS WEEKEND MUCH OF THE REGION
WILL SEE RELATIVE HUMIDITY DROP INTO THE LOW 20 PERCENT RANGE WITH
THE SOUTHWESTERN PORTIONS OF IDAHO COUNTY, ID DROPPING INTO THE
TEENS AGAIN.
AVIATION
SCATTERED THUNDERSTORMS ARE POSSIBLE ACROSS SOUTHWEST
MONTANA TODAY, WHICH COULD IMPACT KBTM BRIEFLY WITH GUSTY WINDS.
OTHER TERMINALS CAN EXPECT LIGHT WIND REGIMES.
