AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1100 PM MDT MON APR 4 2016

.SHORT TERM...TONIGHT THROUGH TUESDAY (ISSUED AT 126 PM MDT)

SHORTWAVE AND COLD FRONT APPROACHING THE WEST WITH WIDESPREAD
SHOWERS AND A FEW TSTMS EXPECTED THROUGH AT LEAST 00Z BEFORE
DECREASING. A QUICK 3 TO 5 INCHES WILL FALL IN THE NW MTNS ABOVE 9
TO 10K FEET. SOME OF THESE SHOWERS AND AN ISOLD TSTM OR TWO WILL
ALSO MOVE EAST OF THE DIVIDE THROUGH THE EVENING...ESPECIALLY THE
I80 CORRIDOR AND IN THE BIGHORN BASIN/CODY FOOTHILLS. A SECONDARY
VORT MAX ROTATES DOWN THE BACKSIDE OF THIS TROUGH ON TUESDAY WITH
COLDER AIR AND EVEN STRONGER WINDS. BEST CHANCE OF SHOWERS WITH
SOME MTN SNOW WILL BE ACROSS THE NRN HALF. THE BIGHORNS WILL
LIKELY GET A QUICK SHOT OF HEAVIER SNOW FOR AT LEAST A FEW HOURS
TUE AFTN ALONG WITH STRONG NW WIND. THE WIND WILL DEFINITELY BE A
FACTOR FOR MUCH OF THE AREA THRU TUE. THE HIGH WIND WATCH FOR
JOHNSON COUNTY BEGINNING TUE AFTN INTO TUE EVENING IS STILL
LOOKING GOOD. NOT MUCH IN THE WAY OF PRESSURE RISES BUT STRONG NW
FLOW THAT WILL HAVE A GOOD CHANCE OF COUPLING AND MIXING TO THE
SFC TO CREATE HIGH WINDS TUE AFTN AND EVE. THE WATCH WILL REMAIN
IN EFFECT FOR JOHNSON COUNTY. OTHERWISE...FOR THOSE THAT DON'T GET
A SHOWER TODAY OR TOMORROW...MOST CAN EXPECT WINDY TO VERY WINDY
CONDS AT TIMES WITH WINDS BEING STRONGER FOR THE LOWER ELEVATIONS
ON TUESDAY. TEMPS ON TUESDAY WILL LIKELY REACH THEIR MAX IN THE
MORNING ACROSS THE NORTH BEFORE STABILIZING OR EVEN FALLING SOME
IN THE AFTERNOON. WIND WILL HAVE A LITTLE BITE TO IT TOMORROW WITH
TEMPS EAST OF THE DIVIDE ONLY IN THE 40S DURING THE AFTERNOON WITH
STRONG NORTHWEST WIND. WEST OF THE DIVIDE WILL BE WINDY BUT NOT AS
STRONG AS EAST BUT TEMPS WILL ONLY BE IN THE 30S MOST OF THE DAY.

.LONG TERM...TUESDAY NIGHT THROUGH MONDAY

NORTHWEST FLOW TO CONTINUE TUESDAY NIGHT...AND BRING A PUSH OF
MOISTURE ACROSS NORTHEASTERN WYOMING. THIS WILL KEEP SHOWERS OVER
THE BIGHORN MOUNTAINS AND ACROSS JOHNSON COUNTY THROUGH EARLY
WEDNESDAY MORNING. ADDITIONALLY...GUSTY WIND TO CONTINUE OVER
NORTHEASTERN WYOMING TUESDAY NIGHT...FINALLY WEAKENING AFTER
MIDNIGHT. THE LULL WEDNESDAY MORNING WILL END DURING THE AFTERNOON
WHEN ANOTHER ROUND OF STRONGER WIND DEVELOPS. AGAIN THESE STRONGER
WINDS WILL FOCUS ON NORTHERN JOHNSON COUNTY...AND SHOULD BE A
SHORTER TIMEFRAME THAN THOSE EXPECTED ON TUESDAY.

OTHERWISE...GENERALLY DRY CONDITIONS UNDER THE INFLUENCE OF THE
RIDGE...WITH WARMING TEMPERATURES EXPECTED THROUGH THURSDAY. THE
AXIS OF THE RIDGE WILL MOVE THROUGH THE AREA LATE FRIDAY
EVENING...PERMITTING A SOUTHWESTERLY FLOW TO RETURN TO THE FORECAST
AREA. MEANWHILE...A SURGE OF MOISTURE IS EXPECTED TO IMPACT THE
DESERT SOUTHWEST BY FRIDAY EVENING. WITH THE SOUTHWEST
FLOW...MOISTURE AND ASSOCIATED SHOWER ACTIVITY LOOKS FAVORABLE TO
RETURN TO THE AREA EARLY SATURDAY MORNING. INSTABILITY WILL
ACCOMPANY THESE SHOWERS BY SATURDAY AFTERNOON...WITH ISOLATED
THUNDERSTORM ACTIVITY POSSIBLE.

THIS SYSTEM ON SATURDAY WILL BEGIN A SERIES OF DISTURBANCES
EXPECTED TO  IMPACT THE AREA THROUGH THE REMAINDER OF THE FORECAST
PERIOD. COVERAGE OF SHOWERS AND THUNDERSTORMS REMAINS UNDER
INVESTIGATION AS MODELS DO VARY ON COVERAGE AND INTENSITY. THIS
CHANGE IN THE WEATHER PATTERN WILL ALSO INTRODUCE SOME COOLER
TEMPERATURES ACROSS THE AREA.
