0426 PM CDT MON JUN 28 2004

AREAS AFFECTED...NRN NV...ERN ORE...SRN ID

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 282126Z - 282330Z

WIDELY SCATTERED STRONG TO SEVERE TSTMS ARE LIKELY OVER PARTS OF THE
INTERIOR NORTHWEST THROUGH THE EVENING. A CONCENTRATED AREA OF WIND
DAMAGE POTENTIAL MAY EVOLVE ACROSS PARTS OF SRN ID AND A WATCH MAY
BE NECESSARY.

SERIES OF MID LEVEL IMPULSES CONTINUE TO LIFT NWD/NEWD AROUND THE
PERIPHERY OF LARGE SCALE UPPER RIDGE SITUATED ACROSS THE
INTERMOUNTAIN WEST. ONE OF THESE FEATURES...CLEARLY EVIDENT IN
SATELLITE IMAGERY...WAS MOVING OVER THE SNAKE RIVER VALLEY BETWEEN
WRN ID AND NERN ORE. SUBSIDENCE IN THE WAKE OF THIS FEATURE HAS
ALLOWED CLEAR SKIES AND STRONG INSOLATION TO OCCUR ACROSS PARTS OF
SRN ID AND NRN NV. MEANWHILE...A BAND OF STRONGER S/SELY MID LEVEL
FLOW WAS DEVELOPING NWD ACROSS NV. VIGOROUS CONVECTION WAS BEGINNING
TO FIRE ACROSS THE HIGHER ELEVATIONS OF NERN NV AND SWRN ID AND THIS
ACTIVITY WILL MOVE INTO AN AXIS OF GREATER INSTABILITY AND DCAPE
ACROSS NRN NV AND SRN ID OVER THE NEXT 1-2 HOURS. WHILE DEEP LAYER
SHEAR REMAINS SOMEWHAT MARGINAL..LIFT ASSOCIATED WITH THE NWD MOVING
NV IMPULSE COUPLED WITH SUFFICIENT INSTABILITY SHOULD RESULT IN
NUMEROUS STORMS CAPABLE OF PRODUCING  DAMAGING WINDS.
