WEATHER PATTERN OVERVIEW:
TONIGHT THROUGH SATURDAY: ZONAL FLOW AND WEAK RIDGING WILL KEEP
THE WEATHER MAINLY DRY WITH ABOVE NORMAL TEMPERATURES. HIGH
TEMPERATURES THROUGH THE WEEKEND RANGE FROM MID TO LOW 40S IN THE
NORTHEAST TO LOW 50S IN THE SOUTHWEST WITH LOWS IN THE 20S
THROUGHOUT THE REGION. WITH LIMITED SNOWPACK REMAINING, THIS WILL
KEEP SNOW MELT AND FLOODING CONCERNS DOWN. THESE CONDITIONS COULD
SLOW ICE BREAK UP ON AREA RIVERS AND INCREASE THE ICE JAM
CONCERNS.
OVER THE WEEKEND THE UPPER FLOW WESTERN CONUS BEGINS TO SPLIT
WITH AN EAST PACIFIC TROUGH MOVING ONSHORE AND STAYING WELL TO THE
SOUTH AS IT MOVES EAST. THIS WILL PULL UP SMALL AMOUNTS OF
PACIFIC MOISTURE ACROSS MONTANA GENERATING MINOR CHANCES (10-30%)
FOR MINIMAL QPF/SNOW WITH SUBTLE SHORTWAVES MOVING THROUGH THE
ZONAL FLOW.
MONDAY ONWARD: THE NEXT UPPER TROUGH MOVES DEEPER INLAND FROM THE
PACIFIC AND PUTS MONTANA INTO A SW FLOW ALOFT BY MONDAY/TUESDAY
WHICH WILL BRING MORE PACIFIC MOISTURE INTO THE AREA WITH CHANCES
FOR SNOW STARTING SUNDAY NIGHT AND CONTINUING FOR A FEW DAYS AS
TEMPS COOL OFF ONCE THE TROUGH HITS THE PLAINS AROUND MID-WEEK,
ARCTIC AIR WILL START FILLING IN BEHIND IT RETURNING US TO NEAR
NORMAL TEMPS.
FORECAST CONFIDENCE & DEVIATIONS:
BLENDED 50% HRRR WINDS FOR DAY 1 WINDS AND 50% NBM90 FOR DAY 1
