KEY MESSAGES:
- THE KMSX RADAR (MISSOULA, MT LOCAL WEATHER RADAR) WILL REMAIN
OFFLINE DUE TO SCHEDULED MAINTENANCE THROUGH AUGUST 9TH
- WARMING AND DRYING TREND THROUGH EARLY NEXT WEEK.
NORTHWEST FLOW WILL REMAIN OVER WESTERN MONTANA AND NORTH CENTRAL
IDAHO TODAY AS HIGH PRESSURE BEGINS TO BUILD TO THE WEST. THIS
WILL TRANSLATE TO SLIGHTLY WARMER TEMPERATURES TODAY WITH A MIX
OF SUN AND CLOUDS. A FEW SHOWERS OR AN ISOLATED THUNDERSTORM WILL
BE POSSIBLE THIS AFTERNOON, MAINLY ALONG THE CONTINENTAL DIVIDE.
SUNDAY THROUGH TUESDAY WILL BE THE WARMEST DAYS OF THE WEEK AHEAD
AS HIGH PRESSURE STRENGTHENS TO THE WEST. THE VALLEYS OF WESTERN
MONTANA WILL RETURN TO THE UPPER 80S OR LOW 90S, WHILE THE LOWERS
VALLEYS OF NORTH CENTRAL IDAHO WARM INTO THE LOW 100S.
FORECAST MODELS NEVER SHOW THE RIDGE ESTABLISHING ITSELF OVER
WESTERN MONTANA AND NORTH CENTRAL IDAHO AND INSTEAD SHOW WAVES OF
ENERGY MOVING THROUGH THE REGION BY MID WEEK. THIS WILL RETURN A
SLIGHTLY COOLER AND MORE ACTIVE PATTERN TO THE REGION. IN
ADDITION, THIS PATTERN WILL FAVOR BREEZY AFTERNOON WINDS.
BY THURSDAY, FORECAST MODELS ARE FAVORING ANOTHER TROUGH OF LOW
PRESSURE APPROACHING THE REGION, DEPICTED BY APPROXIMATELY 80
PERCENT OF MODEL SOLUTIONS. THERE ARE STILL DIFFERENCES IN HOW
DEEP AND WET THIS TROUGH WILL BE, BUT COOLER AND POTENTIALLY
SHOWERY CONDITIONS ARE FAVORED.
AVIATION
AFTER SOME POSSIBLE PATCHY FOG THIS MORNING, THE
WEATHER WILL TURN DRIER AND WARMER FOR THE WEEKEND. A FEW SHOWERS
OR AN ISOLATED THUNDERSTORM ARE POSSIBLE ALONG THE CONTINENTAL
DIVIDE THIS AFTERNOON, BUT MOST LOCATIONS WILL REMAIN DRY.
