120 AM MDT SUN AUG 24 2025
DISCUSSION
A DRY NORTHWEST FLOW ALOFT, COMBINED WITH PERSISTENT EASTERLY
SURFACE WINDS, WILL KEEP THE REGION DRY WITH SEASONABLE TEMPS AND
HIGH RH RECOVERIES THROUGH THE FIRST PART OF THE COMING WEEK.
THERE IS A LOW CHANCE OF SHOWERS AND WEAK THUNDERSTORMS OVER THE
ABSAROKAS/BEARTOOTHS BEGINNING MONDAY AND CONTINUING INTO
WEDNESDAY. WE THEN EXPECT AN INCREASING CHANCE OF SHOWERS AND WET
THUNDERSTORMS ACROSS THE DISTRICTS BY THURSDAY AND FRIDAY AS
MONSOONAL MOISTURE MOVES INTO THE REGION. STORMS MAY BE SLOW
MOVING, THUS COULD PRODUCE SIGNIFICANT LOCAL PRECIPITATION. BT
