DISCUSSION
THROUGH MONDAY...
RIDGING WILL BEGIN BUILDING OVER THE NORTHERN ROCKIES TODAY. COOL
AND DRY CONDITIONS WITH HIGHS IN THE 40S AND 50SF ARE IN STORE
TODAY AS WELL.
WEDNESDAY WILL BE WARMER, WITH HIGHS IN THE 50S TO 60F. MODELS
DEPICT A SHORTWAVE AND AN ASSOCIATED COLD FRONT DROPPING THROUGH
LATE ON WEDNESDAY. CURRENTLY, THIS FRONT LOOKS TO BE DRY, THOUGH
THE BEST CHANCE FOR A SHOWER OR TWO WOULD BE ALONG THE DAKOTAS
BORDER. THE MAIN IMPACT WITH THIS FRONT WILL BE BREEZY NW WINDS,
WITH GUSTS IN THE 20-40S MPH (HIGHEST NORTH AND WEST OF BILLINGS).
AS THE SHORTWAVE BECOMES AN UPPER LOW IN SOUTHERN CANADA AND
DROPS THROUGH THE DAKOTAS, EXPECT BREEZY WINDS TO RETURN THURSDAY
AFTERNOON AND EVENING IN THE FAR EAST.
RIDGING BRIEFLY REBUILDS FOR FRIDAY, BRINGING COOL AND DRY
CONDITIONS FOR HALLOWEEN WITH HIGHS IN THE 40S TO MID 50S.
THE RIDGE BEGINS TO FLATTEN SATURDAY THROUGH SUNDAY.
CONCURRENTLY, A FAVORABLE PRESSURE GRADIENT FOR THE LIVINGSTON AND
NYE GAP WINDS BUILDS. CONFIDENCE FOR WINDS TO REACH 50 MPH IS
MODERATE AT THIS TIME, WITH 700MB WINDS BEING ON THE LOWER END (30
KNOTS). ANOTHER ROUND OF BREEZY WINDS WILL SPREAD ACROSS THE AREA
ON SATURDAY WITH THE RIDGE FLATTENING AND FLOW BECOMING ZONAL TO
NORTHWESTERLY.
GUSTIER WINDS ARE CURRENTLY FORECAST FOR SUNDAY INTO MONDAY AS
850-500MB WINDS INCREASE GREATLY, WITH JET DYNAMICS MOVING ACROSS
THE REGION FROM AN ALASKAN LOW. UNCERTAINTY REMAINS HIGH WITH THE
CHANCE OF PRECIPITATION OVER THE WEEKEND, THOUGH THE CURRENT
FORECAST HAS A LOW CHANCE.
MATOS
AVIATION
VFR CONDITIONS WILL PREVAIL TODAY. WHILE LOW LEVEL
WIND SHEAR IS EXPECTED EARLY THIS MORNING AROUND KSHR AND KMLS,
WINDS ALOFT WILL DECREASE BY MID-MORNING, ENDING THIS THREAT.
