AREAS AFFECTED...CNTRL AND SRN ORE

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 282252Z - 290015Z

SEVERAL BANDS OF THUNDERSTORMS ARE CURRENTLY ONGOING IN SRN ORE. AS
THE STORMS SPREAD NNWWD...HAIL AND STRONG GUSTY WINDS WILL BE
POSSIBLE WITH THE STRONGER ROTATING STORMS.

WATER VAPOR IMAGERY SHOWS AN UPPER-LOW MOVING EWD INTO NRN CA. A
CLEAR SLOT IS EVIDENT EAST OF THE CASCADES WHERE RISING TEMPS AND
SFC DEWPOINTS IN THE 50S F ARE RESULTING IN MLCAPE VALUES NEAR 1000
J/KG. THIS COMBINED WITH MODERATE VERTICAL SHEAR SHOWN ON OBJECTIVE
ANALYSIS WILL BE SUFFICIENT FOR A FEW ORGANIZED STORMS AS CELLS
INITIATE OVER THE ERN SLOPES OF THE CASCADES EARLY THIS EVENING. THE
STEEP LAPSE RATES IN PLACE AND RELATIVELY COLD AIR ALOFT (500 MB
TEMPS AROUND -16C) SHOULD BE SUFFICIENT FOR HAIL WITH THE STRONGER
ROTATING STORMS. A MARGINAL WIND DAMAGE THREAT COULD ALSO
MATERIALIZE CONSIDERING 0-2 KM LAPSE RATES EXCEED 8.0 C/KM EAST OF
THE CASCADES.
