DISCUSSION
TODAY THROUGH MONDAY NIGHT...
A COLD FRONT CURRENTLY PASSING OVER SOUTHEASTERN MONTANA IS
SHIFTING WINDS TO THE NORTHWEST AND BRINGING WITH IT COOLER
TEMPERATURES, WITH HIGHS IN THE UPPER 70S TO LOW 80S TODAY,
THAT WILL HELP KEEP HUMIDITIES FROM DROPPING BELOW 20 PERCENT.
WINDS IN EASTERN MONTANA WILL MIX DOWN AND GUST UP TO 30 MPH
LATE THIS MORNING THROUGH THE AFTERNOON.
WINDS WILL SHIFT TO THE SOUTHEAST MONDAY MORNING, THOUGH WITH
LITTLE MOISTURE RETURNS WITH IT. ZONAL FLOW ALOFT WILL DOMINATE
THE WEATHER PATTERN, BUT A WEAK SHORTWAVE IS POSSIBLE LATE MONDAY THAT
BRINGS A SMALL CHANCE FOR THUNDERSTORMS TO THE MOUNTAINS.
TEMPERATURES WILL REBOUND, WITH HIGHS IN THE MID 80S.
VERTZ
TUESDAY THROUGH SATURDAY...
DRY WESTERLY FLOW WILL PERSIST TUESDAY WITH TEMPERATURES BOOSTED
INTO THE 90S FOR MOST LOCATIONS. THE STORM TRACK ACROSS SOUTHERN
CANADA WILL BECOME ACTIVE AFTER MIDWEEK, DRAGGING SOME COLD FRONTS
ACROSS OUR CWA. THIS MEANS A CHANCE OF ISOLATED TO WIDELY
SCATTERED THUNDERSTORMS TRACKING ACROSS OUR REGION EACH DAY.
AFTERNOON HIGHS WILL BE A LITTLE COOLER THAN TUESDAYS DUE TO
CLOUD COVER, WITH READINGS IN THE MID 80S TO LOWER 90S. BT
AVIATION
VFR CONDITIONS WILL PREVAIL TODAY. SURFACE WINDS WILL BE PRIMARILY
FROM THE NORTH OVER THE LOWER ELEVATIONS. BT
