Damaging Wind in Wyoming, June 4, 2014

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE RIVERTON WY
1201 PM MDT WED JUN 4 2014

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT

ANOTHER SHORT WAVE MOVES THROUGH TODAY WITH MORE VERY WINDY SHOWERS
AND THUNDERSTORMS EXPECTED. WE ARE STILL LIMITED BY MOISTURE AS THE
RICHER DEW POINTS REMAIN WELL TO THE EAST...BUT THERE IS STILL
ENOUGH TO WORK WITH ACROSS MOST OF THE FORECAST AREA...WITH THE
EXCEPTION OF SWEETWATER COUNTY WHERE THE BONE DRY SOUTHWEST FLOW
REMAINS. THE BEST MOISTURE AND INSTABILITY WILL AGAIN BE ALONG THE
I25 CORRIDOR AND INTO THE BIGHORN BASIN. THIS TROUGH IS A LITTLE
SLOWER TO MOVE THROUGH SO SOME SHOWERS AND STORMS ARE EXPECTED TO
LAST LONGER INTO THE EVENING.

WARM AND QUITE DRY ON THURSDAY AS A COLD FRONT APPROACHES FROM THE
NORTH. SOME UPSLOPE FLOW IS POSSIBLE ALONG THE I25 CORRIDOR...ENOUGH
FOR A STORM OR TWO WITH A REAL THREAT FOR DRY THUNDERSTORMS WITH
VERY GUSTY WINDS. THE COLD FRONT MAKES PROGRESS SOUTH DURING THE
EVENING HOURS...ENDING UP ALONG THE DIVIDE BY MORNING...DRAGGING
ALONG MUCH RICHER MOISTURE...COOLER TEMPS AND A WIND SHIFT. THIS
WILL SET THE STAGE FOR SOME MORE THUNDERSTORM ACTIVITY ON FRIDAY.
THERE WILL BE MUCH MORE MOISTURE TO WORK WITH...ESPECIALLY ALONG AND
EAST OF THE DIVIDE AS ANOTHER TROUGH APPROACHES. LATEST MODEL RUNS
BRING THE TROUGH IN A BIT SLOWER...HOLDING BACK THE BROAD LIFT
ASSOCIATED WITH THE FRONT SIDE OF THE TROUGH UNTIL LATE IN THE
AFTERNOON INTO EARLY EVENING. HOWEVER...THERE WILL BE ENOUGH
INSTABILITY AND LIFT PROVIDED BY THE MOUNTAINS IF THE SKIES ARE
CLEAR ENOUGH FRIDAY MORNING BEHIND THE FRONT. THE SOUTHWEST FLOW
SETTING UP WITH THE APPROACHING TROUGH MAY CAUSE THE FRONT TO
RETREAT FURTHER NORTH...SETTING UP A DRY LINE OF SORTS AS THE VERY
DRY AND WARM SOUTHWEST FLOW IS ESTABLISHED. THIS COULD CREATE A SHARP
BOUNDARY FOR THE STORMS TO FIRE UPON...IT WOULD ALSO SET UP A ZONE
OF INCREASED LOW LEVEL SHEAR NEEDED FOR MORE ORGANIZED STORMS. THE
FRONT PUSHES BACK TO THE SOUTH IN THE EVENING WITH SHOWERS AND
STORMS EXPECTED TO CONTINUE EAST OF THE DIVIDE OVERNIGHT.

.LONG TERM...SATURDAY THROUGH WEDNESDAY

FRIDAY'S UPPER TROUGH PUSHES MORE ABUNDANT MOISTURE TO OUR EAST ON
SATURDAY...LEAVING SFC HIGH PRESSURE OVER THE NORTHERN HIGH PLAINS
AND STATIONARY FRONT ALONG THE EAST SLOPES OF THE DIVIDE...E-NE SFC
FLOW BEHIND THE FRONT AND A DRIER WNW SFC FLOW WEST OF THE DIVIDE.
THE MAIN CHANGE ADVERTISED BY ECMWF AND GFS IS NOT QUITE AS COLD OF
AN AIRMASS ACROSS NE WY AND MUCH MORE INSTABILITY IN THE VCNTY OF
THE FRONTAL BOUNDARY.  CYCLONIC WNW FLOW CONTINUES ALOFT WITH
SEVERAL RIPPLES IN THE FLOW.  THIS WILL SET THE STAGE FOR
THUNDERSTORMS TO DEVELOP NEAR THE FRONTAL BOUNDARY...THE BEST
COVERAGE AND STRONGER STORMS EXPECTED FROM THE SOUTHERN BIG HORN
BASIN SOUTH ACROSS FREMONT AND NATRONA COUNTIES.  THE NORTHERN
BIGHORN RANGE COULD STILL SEE A FEW INCHES OF SNOW SATURDAY MORNING
NEAR 9KFT AND HIGHER.

BOTH GFS AND ECMWF KEEP UNSETTLED NW FLOW AROUND A BIT LONGER
THROUGH THE WEEKEND WITH ANOTHER SHORTWAVE DIVING SOUTHEAST ACROSS
WYOMING ON SUNDAY.  THE ECMWF IS ON THE FAST END OF GUIDANCE WITH
S/W INTO THE HIGH PLAINS 18Z SUNDAY WHILE THE GFS HAS IT CROSSING
THE WY DIVIDE.  STATIONARY FRONT WILL BE IN THE SAME POSITION ALONG
THE EAST SLOPES OF THE DIVIDE WITH BETTER INSTABILITY ALONG AND EAST
OF INTERSTATE 25 THAN ON SATURDAY.  SO JUST A MATTER OF TIMING...BUT
ANOTHER ACTIVE DAY EXPECTED WITH THUNDERSTORMS FIRING OFF ALONG AND
EAST OF THE FRONTAL BOUNDARY.

A DRIER AND WARMER WESTERLY FLOW IS EXPECTED ACROSS MOST OF THE AREA
ON MONDAY WITH FRONTAL BOUNDARY RETREATING...LEE SFC TROUGH EXPECTED
TO BE OVER EASTERN WYOMING IN THE AFTERNOON.  BEST CHANCE OF
THUNDERSTORMS WILL BE ALONG AND EAST OF INTERSTATES 25/90.

ON TUESDAY AND WEDNESDAY...UPPER RIDGE BUILDS IN THE EASTERN PACIFIC
ALONG 140-150W WITH TROUGH DIGGING NEAR 120W IN RESPONSE.
DETERMINISTIC RUNS BECOME MUCH LESS RELIABLE HERE.  EC ENSEMBLE MEAN
STILL HOLDS MEAN TROUGH POSITION ALONG 120W OR NEAR THE NW COAST
THROUGH WEDNESDAY.  BACKING SW FLOW ACROSS WYOMING ON TUESDAY WILL
BRING MUCH WARMER AND BREEZY/WINDY CONDITIONS ACROSS MUCH OF THE
AREA WITH LEE SFC TROUGH EXPECTED IN ITS USUAL POSITION IN THIS
FLOW...RUNNING NORTH ALONG THE LARAMIE RANGE AND WWD INTO THE
NORTHERN BIG HORN BASIN...ISOLATED TO WIDELY SCT THUNDERSTORMS ALONG
AND N-E OF THE SFC TROUGH.   PRETTY MUCH A REPEAT ON WEDNESDAY PER
ECEM.

.AVIATION.../18Z ISSUANCE/

EAST OF THE DIVIDE...KCOD/KCPR/KLND/KRIW/KWRL ROUTES

ANOTHER DISTURBANCE WILL MOVE THROUGH THE AREA THIS AFTERNOON AFTER
19Z AND BRING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. SIMILAR
THREATS OF GUSTY AND ERRATIC WIND AND FREQUENT LIGHTNING ARE
ANTICIPATED FOR THIS AFTERNOON AND EVENING. GENERAL WIND OUTSIDE OF
THUNDERSTORM ACTIVITY WILL ALSO INCREASE WITH THE DISTURBANCE
PASSAGE...ESPECIALLY FOR KLND...KCPR AND KRIW WHERE GUSTY WIND IS
ANTICIPATED. THE BEST CHANCE FOR SMALL HAIL AND LOCALLY HEAVY
RAINFALL WILL BE OVER NORTHERN AND EASTERN WY. MOST CONVECTION
SHOULD END AFTER 4Z THURSDAY.

WEST OF THE DIVIDE...KBPI/KJAC/KPNA/KRKS ROUTES

ANOTHER DISTURBANCE WILL MOVE THROUGH THE AREA THIS AFTERNOON AND
EVENING...BRINGING ANOTHER ROUND OF ISOLATED SHOWERS AND
THUNDERSTORMS. ACTIVITY WILL MAINLY STAY CONFINED TO THE WESTERN
MOUNTAINS...THOUGH SOME GUSTY WIND WILL WORKS ITS WAY TO THE LOWER
ELEVATION TERMINALS...INCLUDING KJAC...KPNA AND KBPI. THE
DISTURBANCE WILL INCREASE GENERAL WIND SPEEDS ACROSS THE AREA THIS
AFTERNOON. MOST CONVECTION SHOULD END AFTER 5Z THURSDAY.

&&

.FIRE WEATHER...

AN UNSTABLE ATMOSPHERE WILL CONTINUE FOR THE NEXT COUPLE DAYS ACROSS
THE FORECAST AREA. GUSTY AND ERRATIC WIND WITH FREQUENT LIGHTNING
WILL REMAIN THE PRIMARY THREATS WITH ACTIVITY TODAY ACROSS
NORTHERN AND CENTRAL WYOMING. TEMPERATURES WILL BE SIMILAR ON
TODAY AS WHAT WAS EXPERIENCED ON TUESDAY...WITH CONTINUED LOW
HUMIDITY. ANOTHER DAY OF MODERATE TO HIGH HAINES INDEX IS
EXPECTED...WITH A HAINES OF 6 EXPECTED ACROSS MUCH OF RAWLINS
DISPATCH AREA. A COLD FRONT DROPS IN FOR FRIDAY WITH MUCH HIGHER
HUMIDITY AND A BETTER CHANCE OF WETTING RAIN ALONG AND EAST OF THE
DIVIDE.
