AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
333 AM MDT WED APR 13 2011

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...
WEAK SHORTWAVE MOVING OVERHEAD EARLY THIS MORNING WAS HAVING VERY
MINIMAL IMPACT. IN FACT...IR IMAGERY SHOWS WARMING CLOUD-TOPS
SINCE AROUND MIDNIGHT. LINGERING SHOWERS WILL CONTINUE TO BE A
POSSIBILITY THIS MORNING HOWEVER...AS AN AREA OF WEAK ISENTROPIC
LIFT PERSISTS ALONG 295K MAINLY NORTH OF A WHEATLAND TO ALLIANCE
LINE. THE COVERAGE WILL BE LIMITED SO WOULD EXPECT MOST PLACES TO
REMAIN DRY. MORNING SATELLITE IMAGERY SUPPORTS THE IDEA OF A 6 TO
9 HOUR BREAK IN BETWEEN SYSTEMS. SKIES ARE MOSTLY CLEAR OVR MUCH
OF WRN CO...UT...AND EVEN INTO ERN NEVADA AT THIS HOUR. SO...WOULD
NOT BE SURPRISED IF MUCH OF THE AREA WILL REMAIN DRY FROM LATE
THIS MORNING THRU MID/LATE THIS AFTERNOON. NEGATIVELY TILTED
TROUGH WILL MOVE FROM THE GREAT BASIN LATE THIS AFTERNOON INTO WRN
COLORADO BY AROUND MIDNIGHT. AS A RESULT...FLOW WILL BACK TO THE
SOUTHWEST INTO THE CWA. MODELS DIFFER ON THE TIMING OF ONSET OF
PRECIPITATION WITH THE GFS THE QUICKEST BRINGING CONVECTION IN BY
LATE AFTERNOON. MEANWHILE..THE NAM WAS SLOWER DELAYING CONVECTIVE
INITIATION UNTIL AFTER 6P. PREFER THE SLOWER NAM...BUT HAVE KEPT
COVERAGE ISOLATED ALONG AND WEST OF THE LARAMIE RANGE MAINLY LATE
THIS AFTERNOON TO GIVE SOME WIGGLE ROOM FOR THE QUICKER GFS.
LIFTED INDICES WILL BE BETWEEN 0 AND -2C LATE THIS AFTERNOON IN
CARBON COUNTY. THIS WILL BE SUFFICIENT FOR A FEW THUNDERSTORMS...
ESPECIALLY LATE THIS AFTERNOON/EARLY THIS EVENING. WOULD EXPECT
CONVECTION TO BECOME ELEVATED AND BE ABLE TO BE SUSTAINED WELL
INTO THE NIGHTTIME HOURS...SO KEPT THUNDER IN UNTIL AT LEAST
MIDNIGHT. WOULD NOT BE AT ALL SURPRISED IF ITS NEEDED LONGER. LOW
FREEZING LEVELS WILL SET THE STAGE FOR THE POSSIBILITY OF GRAUPEL
AND/OR SMALL HAIL WITH THE HEAVIER CONVECTIVE SHOWERS THIS
EVENING. SNOW LEVELS WILL CLIMB TO AROUND 9000 OR 10000 FEET THIS
AFTERNOON...BUT WILL FALL ONCE AGAIN TO THE VALLEY FLOORS LATE
THIS EVENING AND OVERNIGHT. SO...PRECIP WILL REMAIN LIQUID THRU
MUCH OF THE DAY TODAY...BUT WILL MIX WITH SNOW BY LATE THIS
EVENING AND TRANSITION TO SNOW AFTER MIDNIGHT. THE NEGATIVELY
TILTED TROUGH WILL CONTINUE INTO SE COLORADO BY EARLY THURSDAY AND
CLOSE OFF OVER WRN KANSAS ON THURSDAY AFTERNOON. 00Z MODEL SUITES
HAVE CONTINUED THE SLOWER/WETTER TREND WITH THIS SYSTEM. AS THE
UPPER LOW CLOSES AND STACKS...ITS PROGRESSION WILL SLOW TO A
CRAWL. AS THIS OCCURS AN IMPRESSIVE AREA OF DIVERGENCE DEVELOPS
WITHIN DIFFLUENT H3 FLOW. THIS WILL MOVE OVER TOP OF AN AREA OF
STRONG LOW-LEVEL CONVERGENCE WHICH WILL PROVIDE A FAVORABLE SET-UP
FOR PRECIPITATION THURSDAY. HAVE CONTINUED TO INCREASE PRECIP
CHANCES ACROSS THE BOARD FOR THURSDAY AND THURSDAY NIGHT. IF TEMPS
ARE ABLE TO REMAIN COLD ENOUGH...AREAS OF THE NRN PANHANDLE COULD
SURPASS ADVISORY CRITERIA SNOW AMOUNTS. THIS WILL COMBINE WITH
NORTHWEST WINDS OF AT LEAST 15 TO 25 MPH AND PERHAPS HIGHER TO
CREATE AREAS OF BLOWING AND DRIFTING SNOW. THIS PERIOD WILL NEED
TO BE MONITORED CLOSELY AS ANY DEVIATION IN LOW POSITION WOULD
HAVE RESIDUAL CONSEQUENCES ON THE OUTCOME. THE UPPER LOW WILL
WOBBLE INTO CENTRAL KANSAS THURSDAY NIGHT AND INTO ERN KANSAS
FRIDAY MORNING. AS THIS OCCURS...DRIER CONDITIONS WILL WORK IN
FROM WEST TO EAST ON FRIDAY AND FRIDAY NIGHT. SO...FOR TOTAL SNOW
ACCUMULATIONS...HAVE 3 TO 7 INCHES IN THE SNOWIES/SIERRA
MADRES/LARAMIE RANGE...WITH PERHAPS 1 TO 3 INCHES IN ADJACENT
LOWER ELEVATIONS. KEPT HIER AMOUNTS GOING IN THE WRN NEBRASKA
PANHANDLE...WHERE 2 TO 5 INCHES FO SNOW WILL BE POSSIBLE. H7
TEMPERATURES WILL DROP TO AROUND -8C ON THURSDAY AND WHEN COMBINED
WITH THICK CLOUDS WILL ONLY YIELD UPPER 30S/LOW 40S FOR HIGHS.
SOME MODERATION BACK INTO THE UPPER 40S IS EXPECTED BY FRIDAY.

.LONG TERM...SATURDAY THROUGH TUESDAY...
UNSETTLED WEATHER WILL OCCUR EACH DAY THROUGH THE EXTENDED PERIOD.
WARMER TEMPERATURES WILL BE NOTED ON SAT AS THICKNESS VALUES
INCREASE OVER THE CWA. A DISTURBANCE ALONG WITH MID LEVEL MOISTURE
WILL PRODUCE A CHANCE OF RAIN AND SNOW SHOWERS WEST OF THE LARAMIE
RANGE SAT. WESTERLY FLOW WILL BE ALOFT OVER THE FORECAST AREA FROM
SAT NIGHT THROUGH SUN NIGHT AND THIS WILL PROVIDE A STEADY STREAM
OF MOISTURE FROM THE PACIFIC. SEVERAL WEAK DISTURBANCES WILL MOVE
ACROSS THE AREA AT THIS TIME AND THIS WILL RESULT IN A CHANCE OF
RAIN AND SNOW SHOWERS FROM SAT NIGHT THROUGH SUN NIGHT. PRECIP
AMOUNTS DURING THIS TIME SHOULD REMAIN LIGHT. ON MON...THE UPPER
FLOW WILL BECOME SW AS AN UPPER TROUGH DEEPENS TO THE WEST. THIS
UPPER TROUGH WILL BEGIN TO MOVE ACROSS THE CWA MON NIGHT WITH THE
ASSOCIATED COLD FRONT ALSO MOVING ACROSS THE AREA AT THIS TIME.
A 700 MB CLOSED LOW WILL ALSO BE OVER THE FORECAST AREA MON NIGHT.
THIS SYSTEM APPEARS THAT IT WILL BE MUCH STRONGER THAN THE WEAK
DISTURBANCES EARLIER IN THE EXTENDED PERIOD...AND SIGNIFICANT
AMOUNTS OF PRECIPITATION WILL OCCUR ACROSS MUCH OF THE FORECAST
AREA. THE PRECIP WILL REMAIN RAIN MON EVENING...BUT WILL LIKELY
CHANGE TO SNOW EARLY TUES MORNING BEFORE CHANGING BACK TO RAIN BY
TUES AFTERNOON. SIGNIFICANT SNOW AMOUNTS ARE POSSIBLE IN THE
SOUTHERN MOUNTAINS. HIGH TEMPERATURES WILL BE FROM 4 TO 7 DEGREES
ABOVE NORMAL FOR SAT AND SUN...AROUND NORMAL ON MON...AND A FEW
DEGREES BELOW NORMAL ON TUE.

&&

.AVIATION...12Z TAFS
AREAS OF MVFR CONDITIONS WILL OCCUR MAINLY EAST OF THE LARAMIE
RANGE THIS MORNING DUE TO SHOWER ACTIVITY AND LOWER CIGS. VFR
CONDITIONS WILL PREVAIL THIS AFTERNOON ACROSS THE AREA. AREA OF
MVFR CONDITIONS WILL RETURN TO THE AREA TONIGHT DUE TO RAIN AND
SNOW SHOWERS REDUCING VSBYS AND CIGS. SOME BRIEF IFR CONDITIONS
ARE ALSO POSSIBLE ACROSS THE WESTERN PORTION OF THE AREA TONIGHT
INTO THUR MORNING.

&&

.FIRE WEATHER...
ANOTHER DISTURBANCE WILL PUSH INTO THE DISTRICT BY LATE AFTERNOON
AND TONIGHT. THIS WILL BRING ANOTHER GOOD CHANCE OF WIDESPREAD
PRECIPITATION TONIGHT THROUGH THURSDAY NIGHT. TEMPERATURES DROP
TONIGHT SUCH THAT MUCH OF THE PRECIPITATION WILL MIX WITH AND TURN
TO SNOW. MOST AREAS CAN EXPECT AT LEAST SOME ACCUMULATING SNOW
WITH THIS SYSTEM. ADDITIONALLY...STRONG NORTHWEST WINDS WILL
DEVELOP THURSDAY NIGHT AND FRIDAY. THE SYSTEM WILL PULL AWAY FROM
THE AREA ON FRIDAY...GRADUALLY ENDING PRECIPITATION CHANCES FROM
WEST TO EAST. COOL TEMPERATURES AND UNSETTLED CONDITIONS WILL KEEP
RELATIVE HUMIDITIES HIGH THROUGH THE END OF THE WEEK. ALTHOUGH
THIS SYSTEM LOOKS THE STRONGEST IN THE FORESEEABLE FUTURE...
ADDITIONAL DISTURBANCES WILL BRING PERIODIC CHANCES FOR THE LATTER
HALF OF THE WEEKEND AND INTO EARLY NEXT WEEK.

&&

.HYDROLOGY...
RIVER LEVELS ON THE NORTH PLATTE DOWNSTREAM OF GUERNSEY RESERVOIR
WILL REMAIN NEAR STEADY THROUGH WEDNESDAY. AFTER THAT
TIME...ADDITIONAL LIQUID PRECIPITATION OF UP TO ONE HALF INCH WILL
CAUSE WATER LEVELS IN RIVERS...ESPECIALLY IN THE PANHANDLE TO RISE
SLIGHTLY BY THURSDAY AND CONTINUE FOR FRIDAY. THE STAGES AT THE
GAGE SITES AT HENRY AND MITCHELL WILL REMAIN IN THE ACTION STAGE
FOR THE FORESEEABLE FUTURE.
