AS A LEE SIDE TROUGH DEEPENS AND STRONG SURFACE PRESSURE AND TEMPERATURE GRADIENT WILL DEVELOP. CONDITIONS WILL BE DRY WITH INCREASING TEMPERATURES THROUGH SUNDAY. THIS WILL CONTINUE TO MELT LOW LEVEL SNOW PACK INCREASING RUN OFF AND ALSO MELT ICE COVER IN THE RIVERS CONTINUING THE THREAT OF ICE JAM FLOODING. WILL EXTEND AREAL FLOOD ADVISORIES THROUGH SUNDAY AFTERNOON. .LONG TERM...SUNDAY NIGHT THROUGH SATURDAY ANOTHER STORM SYSTEM APPROACHES ON SUNDAY NIGHT...GIVING THE MOISTURE FROM THE EASTERN PACIFIC SOMETHING TO WORK WITH AS THE FLOW FLATTENS AND THE JET BEGINS TO AGITATE AN APPROACHING WAVE. MOST OF THE PRECIPITATION WILL REMAIN IN THE NORTHWEST SUNDAY NIGHT WITH SOME RAIN CHANGING TO SNOW IN THE VALLEYS BELOW 7000 FEET. RAIN AND SNOW WILL SPREAD SOUTH AND EAST EARLY IN THE MORNING...BRINGING SOME MORE RAIN TO STAR VALLEY AND LINCOLN COUNTY AROUND SUNRISE...AS THE MORNING GOES ON...THE UPPER LEVELS BECOME MORE AND MORE DIVERGENT AS A STRONG TROF CONTINUES TO DIG TO OUR WEST...BRINGING THE RAIN OVER THE WYOMING AND SALT RANGES AND INTO THE UPPER GREEN RIVER BASIN. OVERALL...THE MOST ROBUST FORCING FOR ASCENT ARRIVING MONDAY NIGHT AND THE PRECIP WILL BECOME MORE WIDESPREAD MONDAY NIGHT AND TUES. SFC FRONT WILL ALSO DROP INTO THE NORTHERN PORTION OF THE FORECAST AREA MONDAY NIGHT INTO TUE MORNING BRINGING INCREASINGLY GOOD CHANCES FOR BASIN PRECIP E OF THE DIVIDE BY MIDNIGHT. IN THE BIGHORN MOUNTAINS...SNOW LVLS WILL START AROUND 8000 FT...BUT WILL ALSO QUICKLY FALL TO BELOW 4000 FEET POST FRONTAL AND AFTER MIDNIGHT IN THE ERN PORTIONS OF JOHNSON COUNTY. OVERALL...SNOW WILL BE MORE PLENTIFUL IN THE WRN MOUNTAINS OVR THE 36 HR PERIOD ENDING TUE MORNING...WITH THE BIG HORNS LOOKING TO GET ABOUT HALF. JOHNSON COUNTY AND THE CODY FOOTHILLS LOOK TO MAKE OUT BEST AT THE LOWER ELEVATIONS WITH WHAT MAY BE LOW END ADVISORY AMOUNTS. CONCERNING THE FLOOD SITUATION...THE STORM ON SUNDAY NIGHT AND MONDAY HAS THE POTENTIAL TO DROP ONE QUARTER TO ONE HALF INCH OF RAIN IN THE WESTERN VALLEYS BEFORE IT CHANGES TO SNOW MONDAY NIGHT. THIS INCLUDES STAR VALLEY...JACKSON VALLEY AND THE UPPER GREEN RIVER BASIN. THE SNOW LEVELS WILL START OUT QUITE HIGH...WITH THE HIGHEST SNOW LEVELS EXPECTED AS YOU HEAD FURTHER SOUTH AND EAST. SO ANY RAIN THAT DOES OCCUR ON THE LOWER ELEVATION SNOW PACK ON MONDAY COULD ADD A SIGNIFICANT AMOUNT OF WATER TO THE WATERSHED AS THERE IS A SIGNIFICANT AMOUNT OF LIQUID MOISTURE STILL CONTAINED IN THIS LOW ELEVATION SNOW. THE GOOD NEWS FOR THE BIGHORN BASIN...WIND RIVER BASIN...NATRONA AND JOHNSON COUNTIES IS THAT THE RAINFALL WILL NOT LAST TOO LONG AS MOST OF THE PRECIPITATION EXPECTED IN THESE AREAS WILL BE ASSOCIATED WITH THE COLD FRONT...TEMPERATURES ARE COLD ENOUGH BEHIND THE FRONT TO QUICKLY CHANGE THE RAIN TO SNOW.

HIGH PRESSURE WILL QUICKLY BUILD INTO THE AREA IN THE WAKE OF THIS SYSTEM...AND RESIDUAL MOISTURE WILL BE AMPLE ENOUGH FOR FOG FORMATION IN THESE LOCATIONS. OTHERWISE...CLEAR AND DRY CONDITIONS WILL PREVAIL THROUGH THE REST OF THE WEEK INTO THE WEEKEND. THE WARMING TREND WILL RETURN WITH THIS PATTERN...WHICH WILL AID IN SNOW MELTING IN THE LOWER ELEVATIONS. FLOODING WILL BE THE MAIN CONCERN THROUGH THIS PERIOD...ESPECIALLY FOR AREAS NEAR RIVERS AND STREAMS. WESTERN PORTIONS WILL CONTINUE TO BE AFFECTED...AS SNOW DEPTHS REMAIN SIGNIFICANT IN STAR VALLEY...NEAR JACKSON...MOOSE...AND MORAN. A WEAK...DRY COLD FRONT WILL MOVE THROUGH ON FRIDAY...WHICH WILL BRING PARTLY TO MOSTLY CLOUDY SKIES TO NORTHWEST AND NORTH-CENTRAL PORTIONS OF THE FORECAST AREA. HIGH CLOUDS COULD ALSO REMAIN ACROSS THESE AREAS ON SATURDAY...WHICH WILL HELP MODERATE THE MELTING SNOW. && .AVIATION.../06Z ISSUANCE/ EAST OF THE DIVIDE...KCOD/KCPR/KLND/KRIW/KWRL ROUTES VFR CONDITIONS WILL OCCUR THROUGH 06Z MONDAY.
