110 PM CDT WED JUL 9 2008

.AVIATION...18Z TAF. TSTMS STARTING TO FIRE JUST TO THE EAST AND
SOUTHEAST OF KGRI AND OVERALL EXPECT THIS ACTIVITY TO REMAIN OUT
OF KGRI BUT DID INCLUDE A VCTS TO ACCOUNT FOR THIS. OVERALL WINDS
WILL BE VARIABLE FOR MUCH OF THE TAF PERIOD BUT WILL SHIFT MORE
SOUTHERLY AFTER 12Z WITH AN INCREASE IN WIND SPEEDS AS WELL. CLOUD
HEIGHTS WILL BE VFR OTHER THAN AN OUTSIDE CHC OF MVFR CLOUDS FOR A
BRIEF TIME WITH TSTMS AROUND THIS AFTN.

PREV DISCUSSION... /ISSUED 429 AM CDT WED JUL 9 2008/

DISCUSSION...MAIN CHALLENGE CONTINUES TO BE THUNDERSTORM CHANCES
OVER THE NEXT FEW DAYS.

WEAKENING SHOWERS/THUNDERSTORMS THAT BARELY MADE IT INTO THE FAR
WESTERN CWA LATE LAST NIGHT HAVE SINCE MET THEIR DEMISE...WITH IR
SATELLITE IMAGERY SHOWING STEADILY WARMING CLOUD TOPS. FURTHER
NORTH...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS CONTINUE TO
TREK SOUTHEAST FROM NORTHWEST THROUGH NORTHEAST NE BEING DRIVEN BY
AN APPROACHING SHORTWAVE IN A CONTINUED NORTHWEST FLOW ALOFT AND
PERHAPS SOME VERY WEAK CONVERGENCE AT H85. ALONG WITH THIS
WAVE...WATER VAPOR IMAGERY SHOWS UPPER RIDGE STILL ANCHORED OVER THE
EASTERN PACIFIC/WEST COAST...WITH SEVERAL PERTURBATIONS EMBEDDED IN
THE LOW AMPLITUDE NORTHWEST FLOW FROM THE PAC NW INTO THE CENTRAL
PLAINS. SOME SUCH ENERGY CAN BE SEEN RIPPLING ACROSS WY...WITH A
MORE ORGANIZED SHORTWAVE CURRENTLY PASSING THROUGH MT AND
NORTHERN WY.

FOR THE MORNING HOURS...SOME SHOWERS AND THUNDERSTORMS SHOULD CLIP
NORTHERN PORTIONS OF THE CWA AS CONVECTION ACROSS NORTHERN NE
CONTINUES TO PRESS SOUTHEAST AHEAD OF SHORTWAVE DIVING SOUTHEAST
THROUGH SOUTHERN SD ATTM. 4KM WRF MODEL SEEMS TO HAVE A GOOD
HANDLE ON THIS ONGOING CONVECTION...AND EVENTUALLY BRINGS IT SOUTH
INTO NORTHERN PORTIONS OF THE CWA LATER THIS MORNING. FOCUS
REMAINS ON THUNDERSTORM POTENTIAL INTO THE AFTERNOON HOURS...AND
00Z MODEL RUNS OF BOTH THE NAM AND GFS HAVE REMAINED FAIRLY
SIMILAR TO THEIR SOLUTIONS FROM 24 HOURS AGO REGARDING HOW THINGS
EVOLVE THIS AFTERNOON. BOTH MODELS SHOW A WEAK SURFACE BOUNDARY
EXTENDING WNW TO ESE ACROSS THE CWA WITH LOW-LEVEL MOISTURE
POOLING ALONG AND NORTH OF THE BOUNDARY. THIS POOLING OF LOW-LEVEL
MOISTURE LEADS TO MLCAPES OF 1500 TO 2000 J/KG DEVELOPING...WITH
LITTLE TO NO CAPPING LEFT THIS AFTERNOON. ADDITIONAL MID-LEVEL
SHORTWAVE ENERGY RIPPLING ACROSS SHOULD HELP TO INITIATE SURFACE
BASED CONVECTION THIS AFTERNOON. GIVEN THE PROGGED INSTABILITY
ALONG WITH EFFECTIVE BULK SHEARS OF 25 TO 35 KTS...COULD SEE SOME
ISOLATED SEVERE STORMS WITH LARGE HAIL AND STRONG WINDS THE MAIN
CONCERNS. NOT REAL CONFIDENT IN HOW THIS WILL ALL PLAY OUT GIVEN
POTENTIAL FOR MORNING CONVECTION TO PASS THROUGH THIS AREA AND
ALTER THE ENVIRONMENT...AND THUS HAVE KEPT POPS IN THE SLIGHT
CHANCE RANGE FOR NOW. THE NORTH/NORTHEAST CWA REMAINS THE
PREFERRED AREA FOR CONVECTION INTO THE EVENING HOURS...BUT FOCUS
SHOULD THEN EVENTUALLY SHIFT NORTH OF THE FORECAST AREA LATER
TONIGHT ALONG THE NOSE OF DEVELOPING LLJ.

SHOULD THEN CATCH A BREAK FROM THE PRECIP THURSDAY AND THURSDAY
NIGHT. MID-LEVEL TEMPS WARM THROUGH THE DAY ON THURSDAY...WITH H7
TEMPS CLIMBING TO +12-14C WHICH SHOULD KEEP THE ATMOSPHERE CAPPED TO
ANY CONVECTION GIVEN THE ABSENCE OF ANY APPRECIABLE FORCING.
SOUTHERLY WINDS WILL BE ON THE INCREASE AS SURFACE LOW PRESSURE
DEEPENS OVER THE NORTHERN HIGH PLAINS AHEAD OF A POTENT UPPER LOW
TRACKING ACROSS SOUTHERN CANADA. AS THE GRADIENT TIGHTENS AHEAD OF
SURFACE TROUGH EXTENDING SOUTHWARD THROUGH THE HIGH
PLAINS...SOUTHERLY WINDS WILL BECOME BREEZY TO WINDY WITH
ATTENDANT WAA HELPING TEMPS CLIMB INTO THE LOWER 90S FOR HIGHS.

AS THE UPPER LOW CONTINUES TO ADVANCE ACROSS SOUTHERN CANADA ON
FRIDAY...IT SENDS A COLD FRONT SOUTH INTO THE NORTHERN CWA BY LATE
FRIDAY AFTERNOON. MAIN QUESTION HERE IS WHETHER CONVERGENCE ALONG
THE BOUNDARY WILL BE SUFFICIENT TO SPARK CONVECTION GIVEN WARM
MID-LEVEL TEMPS STILL IN PLACE AND UPPER FORCING STAYING NORTH OF
THE AREA. COULD VERY WELL STAY CAPPED OFF GIVEN PROGGED MID-LEVEL
TEMPS...BUT CONVERGENCE ALONG THE BOUNDARY IS ALSO QUITE STRONG.
BELIEVE AT LEAST SOME ISOLATED CONVECTION COULD DEVELOP ALONG THE
BOUNDARY...AND HAVE ADDED SLIGHT CHANCE POPS IN TO ACCOUNT FOR THIS
BEGINNING LATE FRIDAY AFTERNOON ACROSS THE NORTHERN CWA AND
SPREADING SOUTH FRIDAY EVENING/OVERNIGHT. IF STORMS CAN INDEED
BREACH THE CAP...INSTABILITY LOOKS SUFFICIENT DESPITE MARGINAL SHEAR
TO SUPPORT SOME STRONG TO SEVERE STORMS.

FOR THE WEEKEND...LATEST RUNS OF THE GFS AND ECMWF ARE IN GOOD
AGREEMENT IN PUSHING THE FRONT SOUTH OF THE CWA AND TAKING BETTER
PRECIP CHANCES WITH IT. THUS HAVE LOWERED POPS DURING THIS
PERIOD...KEEPING LARGELY CONFINED TO THE SOUTHERN CWA. IF MODELS
CONTINUE THIS TREND...WILL LIKELY NEED TO TRIM PRECIP CHANCES MORE
AS LATEST INDICATIONS SUGGEST PRIMARILY DRY CONDITIONS FOR MOST IF
NOT ALL OF THE CWA GIVEN FURTHER SOUTH BOUNDARY POSITION.
