Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Spokane, WA (KOTX), launched 12:00Z, 7.5 hours before the alert went out and 188 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Aug 19, 9:31 AM MDT, 3 hours 59 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MISSOULA MT
931 AM MDT TUE AUG 19 2008
.UPDATE...ADJUSTED POP/QPF/SKY/WEATHER GRIDS FOR TODAY TO ACCOUNT
FOR PRECIP AND THUNDERSTORMS ENTERING THE IDAHO PANHANDLE AND NORTHWEST
MONTANA. INCREASED POPS AND QPF DUE TO REPORTS OF PRECIP AND ADDED
AREAS OF SMOKE TO THE VALLEYS.
&&
.DISCUSSION...AN UNSTABLE ATMOSPHERE AHEAD OF THE TROUGH ALREADY
BEGINNING TO PRODUCE THUNDERSTORMS ACROSS THE IDAHO PANHANDLE AND
NORTHWEST MONTANA. LIGHT PRECIP HAS BEEN REPORTED WITH THESE
STORMS...AS WELL AS WITH DEVELOPING SHOWERS FURTHER SOUTH NEAR THE
SULA AREA. CLOUD COVER WILL THICKEN AND THUNDERSTORMS INCREASE
THROUGHOUT THE DAY AS THIS SYSTEM MOVES INTO THE REGION. A FEW
STORMS MAY BE STRONG WITH GUSTY WINDS AND SMALL HAIL. BUT AT THIS
TIME WIDESPREAD SEVERE WEATHER DOES NOT APPEAR LIKELY. SMOKE
CONTINUES TO LINGER IN MANY OF THE VALLEYS AND IS EXPECTED TO DO
SO THROUGHOUT THE REST OF THE DAY.
&&
.AVIATION...SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS NORTH
CENTRAL IDAHO AND NORTHWEST MONTANA. MAIN THREAT WITH THESE CELLS
WILL BE GUSTY WINDS TO ABOUT 40 MPH. EXPECT TO SEE A LULL IN
ACTIVITY LATER THIS MORNING BEFORE ANOTHER ROUND OF THUNDERSTORMS
FORMS THIS AFTERNOON. GENERALLY ALL TERMINAL SITES WILL BE
AFFECTED BY THIS CONVECTION WITH THE MAIN CONCERNS BECOMING
ERRATIC AND GUSTY WINDS AS WELL LOWERED VISIBILITY IN STRONGER
PRECIPITATION CORES. SMOKE CONTINUES TO LINGER IN THE MISSOULA AND
KALISPELL VALLEYS REDUCING VISIBILITY AND IS EXPECTED TO DO SO
THROUGHOUT THE REST OF TODAY.
&&
.PREV DISCUSSION... /ISSUED 416 AM MDT TUE AUG 19 2008/
DISCUSSION...THE AXIS OF THE RIDGE THAT DOMINATED THE WEATHER
OVER THE NORTHERN ROCKIES FOR THE PAST FEW DAYS HAS FINALLY MOVED
OVER EASTERN MONTANA. A TROUGH CONTINUES TO DIG OFF THE PACIFIC
COAST BRINGING A SOUTHWEST FLOW TO THE REGION. A FEW SHOWERS AND
THUNDERSTORMS HAVE ALREADY FORMED IN THE UNSTABLE ATMOSPHERE AHEAD
OF THIS SYSTEM. THE SHOWERS WILL SUBSIDE LATER THIS MORNING BEFORE
BECOMING MORE WIDESPREAD AS THIS AFTERNOONS HEATING CREATES A MORE
UNSTABLE ENVIRONMENT. THE BEST LARGE SCALE DYNAMICS FOR THIS
SYSTEM WILL MOVE THROUGH NORTHWEST MONTANA WHICH IS WHERE THE BEST
POTENTIAL FOR PRECIPITATION WILL BE. A TIGHTENING SURFACE PRESSURE
GRADIENT ALONG WITH STRONGER WINDS MIXING DOWN FROM ALOFT WILL
MAKE IT A LITTLE BREEZY FOR THIS AFTERNOON AS WELL. ANOTHER WAVE
MOVES THROUGH THE FLOW ON WEDNESDAY AND BRINGS THE POTENTIAL FOR
MORE RAIN. WITH THE ATMOSPHERE BEING MORE STABLE THUNDERSTORMS
WILL NOT BE AS WIDESPREAD AS TUESDAYS EVENT.
A SEASONALLY COLD AND MOIST UPPER LEVEL TROUGH WILL BEGIN TO MOVE
ON TO THE PACIFIC COAST WEDNESDAY NIGHT. AS IT MOVES EASTWARD...IT
WILL PUSH A FAIRLY STRONG COLD FRONT THROUGH THE NORTHERN ROCKIES.
THIS FEATURE WILL CAUSE A SIGNIFICANT COOL DOWN FOR THE
THURSDAY/FRIDAY TIME FRAME...WITH MANY LOCATIONS STRUGGLING TO
RISE MUCH ABOVE 70 DEGREES. ALONG WITH THE FRONT...GOOD UPPER
LEVEL SUPPORT AND AN ASSOCIATED 120 KT JET WILL COMBINE TO
PRODUCE WIDESPREAD PRECIPITATION FOR MOST AREAS WEDNESDAY NIGHT
INTO THURSDAY. WITH AN IMPRESSIVE MOISTURE FEED INTO THIS
SYSTEM...SIGNIFICANT PRECIPITATION AMOUNTS ARE EXPECTED...ESPECIALLY
ACROSS THE HIGHER TERRAIN OF WESTERN MONTANA AND NORTH CENTRAL
IDAHO. WITH SNOW LEVELS DROPPING THURSDAY TO BETWEEN 8500 AND 9000
FEET...SOME LIGHT SNOW ACCUMULATIONS ARE POSSIBLE...MAINLY IN THE
HIGHER ELEVATIONS OF GLACIER PARK.
A SLOW WARMING AND DRYING TREND IS EXPECTED FRIDAY INTO THE
WEEKEND AS AN UPPER LEVEL RIDGE BUILDS OVER THE AREA.
AVIATION...SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS NORTH
CENTRAL IDAHO AND NORTHWEST MONTANA THIS MORNING. MAIN THREAT WITH
THESE CELLS WILL BE GUSTY WINDS TO ABOUT 40 MPH. EXPECT TO SEE A
LULL IN ACTIVITY LATER THIS MORNING BEFORE ANOTHER ROUND OF
THUNDERSTORMS FORMS THIS AFTERNOON. GENERALLY ALL TERMINAL SITES
WILL BE AFFECTED BY THIS CONVECTION WITH THE MAIN CONCERNS BECOMING
ERRATIC AND GUSTY WINDS AS WELL LOWERED VISIBILITY IN STRONGER
PRECIPITATION CORES.
FIRE WEATHER...AN UNSTABLE ATMOSPHERE WILL LEAD TO THUNDERSTORM
DEVELOPMENT THROUGH TODAY. THIS COMBINED WITH STRONG WINDS FROM A
TIGHT SURFACE PRESSURE GRADIENT AND STRONG WINDS MIXING DOWN FROM
ALOFT WILL LEAD TO A CRITICAL FIRE WEATHER SITUATION. RED FLAG
WARNINGS HAVE BEEN POSTED ACROSS THE ENTIRE FORECAST AREA. THE
BEAVER HEAD/DEERLODGE AREA WILL ALSO SEE FAIRLY LOW RELATIVE
HUMIDITIES THAT WILL INCREASE THE FIRE WEATHER DANGER MORE.
