CURRENTLY WIND GUSTS OVER 40 MPH ARE BEING NOTED ACROSS THE CODY FOOTHILLS.

AREA OF LOW PRESSURE RESPONSIBLE FOR THIS STRONG GRADIENT WILL PUSH ACROSS EASTERN MT THIS EVENING...KEEPING MOIST WESTERLY FLOW ACROSS THE WEST. THIS WILL BRING CONTINUED CHANCES FOR LIGHT SNOW ACROSS THE NORTHWESTERN MOUNTAINS...WITH SOME LIGHT RAIN OR FLURRIES ACROSS THE WESTERN VALLEYS...THROUGH TONIGHT. A WEAK COLD FRONT COULD ALSO CLIP NORTHERN JOHNSON COUNTY OVERNIGHT TONIGHT...AND MAY PRODUCE SOME ISOLATED LIGHT RAIN SHOWERS. WEDNESDAY...ISOLATED MORNING PRECIPITATION ACTIVITY WILL DIMINISH BY EARLY MORNING ACROSS JOHNSON COUNTY...AND POSSIBLY HOLDING ON TO THE MID TO LATE MORNING HOURS ACROSS THE NORTHWESTERN MOUNTAINS.

HIGH PRESSURE BUILDS ACROSS THE AREA WEDNESDAY AFTERNOON...DIMINISHING CLOUDS AND BRINGING SIMILAR...PERHAPS SLIGHTLY WARMER...TEMPS TO TUESDAY. .LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY TRANSITORY RIDGE MOVES IN WEDNESDAY NIGHT AND THURSDAY IN ADVANCE OF OUR SHORTWAVE FOR FRIDAY. POTENTIAL FOR HIGH WINDS AHEAD OF OUR FRIDAY SYSTEM IN THE CODY FOOTHILLS. BEHIND OUR FRIDAY SYSTEM IS ANOTHER RIDGE FOR THE WEEKEND BEFORE OUR POTENTIAL SHARP COLD FRONT AND A CHANCE OF SNOW MONDAY. SO DRY AND MILD TO START THE PERIOD BEFORE OUR COLD FRONT SWEEPS SE ACROSS THE AREA ON FRIDAY. MAY NEED ANOTHER HIGH WIND WATCH IN THE CODY FOOTHILLS FOR THURSDAY NIGHT WITH STRONG...STABLE MTN TOP FLOW FORECAST FOR THURSDAY NIGHT AS RIDGE AXIS PASSES TO THE EAST.

SO FOR NOW JUST A CHANCE OF RAIN OR SNOW EAST OF THE DIVIDE MONDAY INTO MONDAY NIGHT BEFORE POTENTIAL CLEARING BY TUESDAY AM.
