AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
158 PM MDT WED JUN 25 2008

.SHORT TERM/LONG TERM...SATELLITE AND RADAR SHOW CONVECTION
DEVELOPING ACROSS THE EASTERN HALF OF THE FCST AREA THIS AFTN.
MOST OF THIS IS OCCURRING OVER THE NORTHERN PORTIONS AND ALONG WY
BORDER. THIS IS IN RESPONSE TO DISTURBANCES LIFTING NNE ACROSS
EASTERN ID AND WY. FCST CALLS FOR ISOLD TSTORMS OVER THE MTNS
SPECIFICALLY IN THE PLACES MENTIONED ABOVE. LIGHTNING...GUSTY WINDS
AND LITTLE RAINFALL CAN BE EXPECTED. UPPER TROF CONTINUES TO PUSH
ASHORE TODAY WITH THE BULK OF THE ENERGY DROPPING TO OFF THE CA
COAST AND FORMING CLOSED LOW. THE NORTHERN PORTION OF THIS TROF
WILL CONTINUE TO SWEEP ACROSS THE NORTHERN ROCKIES AND ON TO THE
EAST TONIGHT AND THURS. THIS WILL DRIVE A COLD FRONT ACROSS THE
AREA. CURRENT MODEL TRENDS PUSH THE FRONT TO WY/UT BORDERS AROUND
NOON. WINDS WILL PICK UP LATER IN THE AFTN INTO THE EVENING.
CURRENT FCST INDICATES LAKE WIND ADVISORY CRITERIA WOULD BE
REACHED BY MID AFTN...BUT WILL LET MID SHIFT TAKE ONE LAST LOOK
AND ISSUE ANY HEADLINES. AHEAD OF THIS FOR TONIGHT...MODELS PUSH A
WEAK DISTURBANCE EAST ACROSS THE AREA...KEEPING A FEW TSTORMS IN
THE FCST ALON THE MT BORDER. BACK TO THURS...AS HE TROF APPROACHES
THE AREA...TSTORMS WILL DEVELOP FIRST OVER THE NORTHERN AND
CENTRAL MTNS AND SPREAD SOUTHEAST. ISOLD TO SCTD POPS HAVE BEEN
INCLUDED IN THE FCST. LOOKING AT SEVERE POTENTIAL TOMORROW...THAT
IS A SOMEWHAT COMPLICATED ISSUE. THE NAM IS GOING GANGBUSTERS ON
SEVERE POTENTIAL WITH VERY LOW LIS AND POCKETS OF SBCAPE NEAR 3000
J/KG OVER THE SNAKE PLAIN AND EASTERN MTNS. MLCAPES OF 750 TO 1500
J/KG ARE FCST FOR THE SAME AREAS. THE GFS IS MUCH MORE STABLE. ONE
WOULD SUSPECT THAT REALITY IS SOMEWHERE IN BETWEEN. BUFR SOUNDINGS
AND OTHER PARAMETERS WOULD INDICATE THAT STRONGER STORMS WOULD
HAVE THE POTENTIAL FOR DOWNBURST WINDS AND PERHAPS SMALL HAIL. AT
THIS TIME...CHOSE TO NOT MENTION ANYTHING IN GRIDDED FCST. EVENING
AND MID SHIFTS WILL HAVE TIME TO LOOK THINGS OVER MORE AND
DETERMINE WHAT WILL TRANSPIRE TOMORROW. BEYOND THURSDAY...RIDGE IS
SILL EXPECTED TO BUILD ACROSS THE ROCKIES AND LOW OFF THE WEST
COAST...PUTTING THE AREA UNDER SOUTH TO SOUTHWEST FLOW ALOFT. GFS
AND ECMWF STILL WANT TO BRING SOME MOISTURE AND ENERGY INTO THE
AREA...WHICH WOULD HELP TO POSSIBLY FIRE OFF TSTORMS. THIS ALSO
SOME HINT THAT HE CLOSED LOW WILL WEAKEN AND ACTUALLY MOVE ACROSS
THE AREA AS AN OPEN WAVE FOR THE FIRST PART OF NEXT WEEK. CURRENT
FCST CALLS FOR ISOLD MTN CONVECTION AND LEFT THIS AS IS. WILL NEED
TO MONITOR EVOLUTION OF CLOSED LOW AND ANY CONVECTION TO OUR SOUTH
AND SOUTHWEST BEFORE MAKING ANY CHANGE ONE WAY OR THE OTHER DOWN
THE ROAD. THE OVERALL STORY WILL BE MUCH WARMER AND DRY.

OF NOTE...MANY AREAS ACROSS IDAHO HAVE BEEN REPORTING SMOKE AND/OR
HAZE IN THE PAST 24 HOURS. FOR THE MOST PART...THERE HAVE BEEN NO
MAJOR PROBLEMS WITH VISIBILITIES EXCEPT FOR SOME VALLEYS IN THE
CENTRAL MTNS. WEB CAMS SHOWED RATHER DENSE SMOKE TRIED TO SETTLE
INTO THESE AREAS AND WOULD EXPECT THIS TO BE A PROBLEM TONIGHT AND
BEFORE THE COLD FRONT ARRIVES TOMORROW. HAVE ADDED HAZE TO THE
VALLEYS OF THE CENTRAL MTNS...SNAKE PLAIN AND THE VALLEYS OF THE
SOUTH CENTRAL HIGHLANDS THROUGH NOON TOMORROW. KEYES

&&

.AVIATION...EXPECT CONTINUED VFR CONDITIONS AT THE TAF SITES THROUGH
THURSDAY.  A COLD FRONTAL PASSAGE MAY CAUSE MOUNTAIN THUNDERSTORMS
THURSDAY.
GK

&&

.FIRE WEATHER...EXPECT ISOLATED MOUNTAIN THUNDERSTORMS THIS EVENING
AND THURSDAY AFTERNOON AND EVENING AS A WEAK COLD FRONT PASSES
THROUGH THURSDAY.  DRY AND MUCH WARMER WEATHER MOVES IN BY THE
WEEKEND AS AN UPPER RIDGE BUILDS OVER THE REGION.

.PIH WATCHES/WARNINGS/ADVISORIES...
NONE.
