AREAS AFFECTED...NWRN MT

CONCERNING...SEVERE THUNDERSTORM WATCH 510...

VALID 212337Z - 220130Z

DAMAGING WIND AND ISOLATED LARGE HAIL WILL REMAIN LIKELY WITH THE
STRONGER STORMS MOVING NEWD THROUGH NWRN MT AND EVENTUALLY N CNTRL
MT MUCH OF THE EVENING.

EARLY THIS EVENING A SURFACE FRONT EXTENDS FROM SERN MT NWWD THROUGH
NWRN MT E OF THE HIGHER TERRAIN. AN AXIS OF BOUNDARY LAYER DEWPOINTS
GENERALLY IN THE 60S EXISTS N OF THIS BOUNDARY WITH MUCH DRIER LOW
LEVEL AIR TO ITS S. FLOW IN THE 850MB TO 700 MB LAYER IS FORECAST TO
VEER AND STRENGTHEN OVER WRN MT LATER THIS EVENING...ENHANCING THE
DOWNSLOPE COMPONENT. THE INCREASING DOWNSLOPE FLOW SHOULD RESULT IN
SOME DRYING OF THE BOUNDARY LAYER FROM THE SW...AND THIS MAY ENHANCE
THE DAMAGING WIND POTENTIAL. OTHERWISE...STRONG VERTICAL SHEAR WILL
CONTINUE TO SUPPORT ORGANIZED STORM STRUCTURES INCLUDING SUPERCELLS
AND BOW ECHOES.
