   ...SYNOPSIS...
   MID AND UPPER LEVEL FLOW WILL CONTINUE TO UNDERGO AMPLIFICATION ON
   THURSDAY AS A TROUGH DEEPENS OVER THE WEST COAST AND NRN
   ROCKIES...A DOWNSTREAM UPPER RIDGE BUILDS OVER THE UPPER MS
   VALLEY...AND A NRN STREAM SHORT WAVE TROUGH...CURRENTLY MOVING SEWD
   FROM SRN CANADA...MERGES WITH SLOW MOVING SRN STREAM IMPULSE AND
   PROMOTES THE DEVELOPMENT OF A CLOSED LOW OVER THE UPPER OH VALLEY.
   
   THE COLD FRONT ASSOCIATED WITH THE NRN STREAM TROUGH WILL EXTEND
   FROM THE ERN GREAT LAKES TO THE CNTRL HIGH PLAINS EARLY IN THE
   PERIOD AND IS FCST TO SWEEP SEWD ACROSS THE OH AND TN VALLEYS BY
   EARLY FRIDAY AS BROAD LOW LEVEL CYCLONE DRIFTS SLOWLY ACROSS THE
   CNTRL APPALACHIANS AND MID ATLANTIC REGIONS.
   
   IN THE WEST...STRENGTHENING AND DIFLUENT UPPER FLOW WILL MAINTAIN
   LARGE SCALE UPWARD MOTION ACROSS THE NRN ROCKIES AS A NUMBER OF
   UPSTREAM IMPULSES...INDICATED ON WV IMAGERY OVER THE EAST
   PACIFIC...CONTINUE TO SPREAD INLAND. 
   
   ...ID/WRN MT...
   BAROCLINIC CLOUD BAND CURRENTLY EVIDENT ON SATELLITE IMAGERY ACROSS
   WA/ORE AREA IS EXPECTED TO DEVELOP INLAND AND BE LOCATED ACROSS
   ID/WRN MT AREA BY EARLY THURSDAY. ETAKF WAS FCSTG MLCAPE VALUES OF
   500-1000 J/KG WILL DEVELOP ALONG/AHEAD OF THE BOUNDARY BY EARLY
   AFTERNOON. STRENGTHENING MID LEVEL FLOW...STRONG FORCING FOR SLOPED
   ASCENT ACROSS THE BOUNDARY WITHIN ENTRANCE REGION OF UPPER
   JET...AND OROGRAPHIC FORCING...WILL ALL CONTRIBUTE TO INCREASING
   TSTM COVERAGE AND INTENSITY. FAVORABLE DEEP LAYER SHEAR AND STEEP
   LAPSE RATES SUGGEST SEVERAL BANDS OR CLUSTERS OF STORMS AND SOME
   SUPERCELLS WILL POSE A THREAT OF LARGE HAIL AND/OR DAMAGING WINDS
   FROM MID AFTERNOON THROUGH THE EVENING FROM THE BOI AREA NEWD TO 
   N-CNTRL MT.
   
   ...OH VALLEY...
   COLD FRONT WILL SPREAD ACROSS THIS REGION DURING THE AFTERNOON WITH
   LIFT ALONG THE BOUNDARY LIKELY PROMPTING INCREASING TSTM
   DEVELOPMENT WITHIN MOIST BUT MARGINALLY UNSTABLE/WEAK LAPSE RATE
   AIRMASS. 12 UTC ETA RUNS APPEAR TO SUGGEST SOME POTENTIAL FOR A
   CORRIDOR OF GREATER SURFACE HEATING AHEAD OF THE FRONT ALONG THE OH
   RIVER VALLEY. TEMPERATURES APPROACHING THE LOWER 80S AND DEWPOINTS
   IN THE LOWER 60S WILL YIELD MLCAPE VALUES AROUND 1000 J/KG WITH
   POCKETS OF 1500 J/KG POSSIBLE IF GREATER HEATING IS REALIZED.
   STRONGER MID LEVEL FLOW AOA 30KT WILL BE JUXTAPOSED WITH FRONTAL
   FORCING AND POTENTIALLY STRONG INSTABILITY ACROSS THE UPPER OH
   VALLEY AREA DURING THE AFTERNOON. THIS COULD LEAD TO THE
   DEVELOPMENT OF GREATER STORM ORGANIZATION WITH A FEW HAIL/WIND
   EVENTS POSSIBLE.
   
   ...SOUTHEAST...
   PREFRONTAL AIRMASS FROM THE TN VALLEY EAST AND SOUTH WILL BECOME
   INCREASINGLY UNSTABLE WITH HEATING OF THE DAY. WEAK CAP AND
   PRESENCE OF REMNANT FRONTAL BOUNDARY AND OUTFLOWS WILL AID STORM
   INITIATION. LARGE SCALE TROUGH AMPLIFICATION AND 25-30KT MID LEVEL
   FLOW MAY PROVIDE SUFFICIENT BACKGROUND FORCING FOR A FEW ORGANIZED
   STORMS WITH AN ISOLD TO SCATTERED WIND DAMAGE HAZARD FROM LATE
   AFTERNOON THROUGH EARLY EVENING.
