.PREV DISCUSSION... /ISSUED 254 AM MDT THU JUN 9 2011/

SHORT TERM...TODAY THROUGH SATURDAY NIGHT

SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE EARLY THIS MORNING
ACROSS WESTERN AND CENTRAL WYOMING AS AN UPPER LEVEL LOW PRESSURE
SYSTEM APPROACHES FROM NORTHERN IDAHO.  MODELS ARE IN REASONABLE
AGREEMENT IN BRINGING THE UPPER LOW OVER WYOMING TODAY AS IT WEAKENS
AND TRANSITIONS TO AN OPEN WAVE.  CLOSE PROXIMITY TO THE LOW AND
DIFLUENCE ON THE NOSE OF A 90KT JEST STREAK WILL STILL KEEP ENOUGH
DYNAMIC FORCING FOR SHOWERS AND ISOLATED THUNDERSTORMS TO CONTINUE
IN THE WEST AND REDEVELOP ELSEWHERE TODAY.  INSTABILITY WILL BE
REDUCED TODAY SO STRONG THUNDERSTORMS ON THE ORDER OF THOSE ON
WEDNESDAY ARE NOT EXPECTED.  WINDY CONDITIONS WILL DEVELOP ALONG THE
ROCK SPRINGS TO CASPER CORRIDOR THIS AFTERNOON AS THE LOW LEVEL
PRESSURE GRADIENT TIGHTENS IN RESPONSE TO THE SURFACE REFLECTION OF
THE LOW TRANSITING SOUTHERN AND EASTERN WYOMING.  HIGH WIND CRITERIA
IS NOT EXPECTED BUT WIND OF 20 TO 30 MPH GUSTING TO 40 MPH IS
LIKELY.  COOLER TEMPERATURES ARE EXPECTED TODAY AS THE UPPER COLD
POOL MOVES OVER WITH THE LOW.  TEMPERATURES WILL RECOVER A BIT ON
FRIDAY AS DRIER CONDITIONS PREVAIL ACROSS MOST OF THE STATE.  THE
NORTHERN THIRD WILL SEE A FEW SHOWERS DURING THE MORNING HOURS AS
MOISTURE WRAPS AROUND TO EXITING LOW.  SEASONABLY COOL TEMPERATURES
AND DRY CONDITIONS WILL ALLEVIATE SOME OF THE FLOODING CONCERNS ON
FRIDAY.  SATURDAY WILL SEE THE APPROACH OF THE NEXT SHORTWAVE TROUGH
BRINGING SHOWERS AND ISOLATED THUNDERSTORMS TO THE WESTERN MOUNTAINS
SATURDAY AFTERNOON.

LONG TERM...SUNDAY THROUGH THURSDAY

THROUGH TUESDAY...MEDIUM RANGE MODELS CONTINUE TO SHOW WEAK
TROUGHINESS OVER THE WEST...AND STRONG RIDGING OVER THE SOUTH
CENTRAL STATES. ALTHOUGH MEDIUM RANGE MODELS STILL DIFFER ON THE
DETAILS...IT APPEARS A SHORTWAVE...AND ASSOCIATED COLD FRONT WILL
IMPACT THE AREA LATE SUNDAY NIGHT THROUGH MONDAY NIGHT. HAVE
INCREASED POPS FOR THIS TIMEFRAME...ESPECIALLY OVER THE NORTHWEST
AND NORTH.

MEDIUM RANGE MODELS HAVE LARGE DIFFERENCES IN HANDLING CURRENT
ENERGY ACROSS THE EXTREME WESTERN PACIFIC NEAR 55 NORTH...150
EAST. MODELS VARY FROM STALLING THIS UPPER LOW OVER THE PACIFIC
NORTHWEST/BRITISH COLUMBIA...ABSORBING THIS SYSTEM...WITH MAINLY
NORTHWEST FLOW OVER THE AREA...TO PUSHING THE UPPER LOW/TROUGH
INTO THE NORTHERN ROCKIES. DUE TO THIS LARGE DISCREPANCY...WILL
HAVE ONLY SLIGHT POPS...MAINLY OVER THE MOUNTAINS FOR NOW...UNTIL
THEIR IS MORE CONSISTENCY.

TEMPERATURES IN THE EXTENDED ARE EXPECTED TO BE SEASONAL TO
SLIGHTLY BELOW AVERAGE.

AVIATION...

UPPER LOW IN WESTERN IDAHO CONTINUES TO PUMP MOISTURE NORTH ACROSS
WYOMING. BEST INSTABILITY EARLY THURSDAY WILL BE EAST OF THE
CONTINENTAL DIVIDE WHERE UPPER LEVEL DIVERGENCE WILL CONTINUE TO AID
SHOWER AND THUNDERSTORM DEVELOPMENT. LOCALIZED MVFR AND MOUNTAIN
OBSCURATIONS IN ASSOCIATION WITH THE EARLY MORNING CONVECTION...
GENERALLY IN THE CORRIDOR OF KLND-KRIW-KWRL. OTHERWISE...TERMINALS
WILL BE VFR INTO THURSDAY AFTERNOON WITH THE EXCEPTION OF KCPR. LOW
LEVEL EAST-NORTHEAST FLOW AS ADVECTED MOISTURE INTO NATRONA COUNTY
AND EVENING CONVECTION LEFT BEHIND COOL AND MOIST AIRMASS. THIS WILL
CREATE MVFR CONDITIONS UNTIL AROUND SUNRISE THURSDAY WHEN DRIER
SOUTHWEST FLOW BEGINS TO ADVECT TOWARD KCPR. UPPER LOW AND
ASSOCIATED MID-LEVEL COLD POOL WILL COMBINE WITH LINGERING MOISTURE
LADEN AIR TO AGAIN GENERATE AFTERNOON AND EARLY EVENING CONVECTION
ON THURSDAY. JET STREAK SET TO ROUND SOUTHERN END OF THE UPPER LOW
WILL ENHANCE CONVECTION IN CENTRAL WYOMING DURING THE LATE
AFTERNOON. EXPECTATION IS THAT BRIEF HEAVY RAIN AND SMALL HAIL...AND
NOT GUSTY OUTFLOW WIND...WILL BE THE MAIN HAZARDS WITH THIS
ACTIVITY. GUSTY WEST-NORTHWEST WIND 15-25KTS WILL FOLLOW IN THE WAKE
OF THIS SYSTEM WITH KBPI...KPNA...AND KRIW THE MOST LIKELY
TERMINALS. CLOUDS WILL BE ON THE DECREASE BY LATE THURSDAY EVENING
ACROSS THE SOUTHWEST QUARTER OF THE STATE. KWRL AND KCOD WILL REMAIN
IN MOIST WRAP-AROUND NORTHWEST FLOW THROUGH THURSDAY EVENING AS
UPPER LOW TRACKS TOWARDS THE DAKOTAS.

HYDROLOGY...

FLOODING CONCERNS CONTINUE ACROSS MUCH OF THE AREA.  COOLER
TEMPERATURES HAVE KEPT SNOWMELT TO A MINIMUM BUT RAINFALL HAS TAKEN
ITS PLACE AS THE PROVIDER TO RUNOFF TO AREA RIVERS AND STREAMS.
THIS SITUATION WILL CONTINUE FOR ONE MORE DAY AS AN UPPER LEVEL
STORM SYSTEM CONTINUES TO BRING PRECIPITATION FOR THE AREA.  SHOWERS
AND THUNDERSTORMS WILL AGAIN BE A CONCERN TODAY AS ANOTHER QUARTER
TO HALF INCH OF RAIN IS EXPECTED IN THE WEST AND IN THE BIG HORN
MOUNTAINS.  SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE
EXPECTED OVER THE REST OF THE AREA AS WELL.  FLOOD ADVISORY REMAINS
FOR YELLOWSTONE NATIONAL PARK AND A FLOOD WARNING REMAINS FOR STAR
VALLEY WITH THE EXPECTED ADDITIONAL RAINFALL TODAY.  A FLOOD WATCH
REMAINS IN EFFECT FOR THE NORTH PLATTE RIVER IN AND NEAR CASPER.
CONSIDERABLE RAINFALL OCCURRED WEDNESDAY IN AREAS DRAINING INTO THE
NORTH PLATTE SO LEVELS WILL NEED TO BE MONITORED FOR FURTHER RISES.
SHOWERS WILL CONTINUE INTO EARLY FRIDAY OVER NORTHERN WYOMING THEN
DRIER CONDITIONS FOR ABOUT 24 HOURS.  SATURDAY WILL SEE WARMER
TEMPERATURES BUT ALSO THE APPROACH OF THE NEXT RAINMAKER WHICH WILL
REACH WESTERN WYOMING SATURDAY EVENING.
