WITH THE UPPER SNAKE HIGHLANDS RECEIVING 2 TO 4 INCHES OF SNOW
MAINLY ALONG THE WYOMING BORDER. EXPECT BREEZY WINDS THIS MORNING
INTO THE AFTERNOON WITH GUSTS OF 25 TO 35 MPH. A STRONG HIGH
PRESSURE RIDGE WILL START BUILDING IN SUNDAY INTO MONDAY. EXPECT
DRY CONDITIONS SUNDAY THROUGH THE REMAINDER OF THE WEEK. THIS HIGH
PRESSURE RIDGING WILL ALSO BRING VALLEY INVERSIONS WHICH WILL
DETERIORATE AIR QUALITY. BY MONDAY EXPECT DAY TIME TEMPERATURES IN
THE 40S FOR MOUNTAIN LOCATIONS SUCH AS STANLEY. WYATT

THE WEST WILL PERSIST THRU THURSDAY. INVERSION CONDITIONS WILL
RESULT IN NIGHTTIME LOW CLDS AND PATCHY FOG IN THE VALLEYS...WHILE

OFF ON PRECIP FOR FRI AND FRI NIGHT AND COME MORE IN LINE WITH THE
GFS IN BRINGING A SPLIT FLOW UPPER TROF INTO THE WEST. MOST OF THE

SLIGHT CHANCES FOR SNOW IN THE MTNS SAT AND SAT NIGHT. HEDGES
