DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0758 PM CDT TUE SEP 04 2007
VALID 050100Z - 051200Z
..THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF NRN UT...
..NRN UT...
LINE OF THUNDERSTORMS ALONG SURFACE COLD FRONT -- EMBEDDED WITHIN
LARGER AREA OF ONGOING SHOWERS AND STORMS AHEAD OF ADVANCING UPPER
TROUGH -- IS MOVING EWD ACROSS THE SALT LAKE CITY REGION ATTM.
WHILE INSTABILITY IS LIMITED...DEEP-LAYER WIND FIELD SUPPORTIVE OF
ORGANIZED CONVECTION SUGGESTS THAT DAMAGING WINDS AND HAIL WILL
REMAIN POSSIBLE FOR THE NEXT 1-2 HOURS OVER NRN UT...BEFORE STORMS
MOVE INTO THE LESS UNSTABLE AIRMASS OVER THE HIGHER TERRAIN OF NRN
UT/SWRN WY.
..NERN MT...
CLUSTER OF THUNDERSTORMS CONTINUES MOVING EWD ACROSS FAR NERN MT
ATTM. THOUGH MID-LEVEL FLOW NEAR 40 KT PER EVENING GGW /GLASGOW MT/
RAOB IS CONTRIBUTING TO SHEAR SUFFICIENT FOR UPDRAFT
ORGANIZATION...STORMS WILL CONTINUE EXITING THE AXIS OF GREATER
INSTABILITY. THIS COMBINED WITH THE LOSS OF DAYTIME HEATING
SUGGESTS THAT ANY REMAINING THREAT FOR GUSTY WINDS OR HAIL SHOULD
PROVE TO BE SHORT-LIVED.
