AREAS AFFECTED...SE ORE/SRN ID/NERN NV/NW UT

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 022125Z - 022330Z

...ISOLD SVR TSTMS POSSIBLE OVER THE NEXT FEW HOURS...

SATELLITE/RADAR LOOPS SHOW INCREASING COVERAGE OF TSTMS ACROSS
MAINLY SRN PORTIONS OF ID AND THE ERN GREAT BASIN THIS AFTN. THIS IS
LIKELY IN RESPONSE TO LARGE SCALE FORCING ASSOCIATED WITH WRN
IMPULSE APPROACHING FROM NRN CA. SFC DEWPOINTS IN THE LOW TO MID 50S
ARE CONTRIBUTING TO A MODERATELY UNSTABLE AIRMASS /MLCAPE VALUES
NEAR 2000 J/KG/ WHICH EXTENDS FROM THE PLATEAU THROUGH MAGIC VALLEY
AND NW UT. LATEST RUC ANALYSIS SUGGESTS DEEP LAYER SHEAR HAS
INCREASED TO AROUND 35-40 KT...WHICH WILL FAVOR ORGANIZED MULTICELLS
OR SUPERCELLS. BACKED ELY WINDS WITHIN THE SNAKE RIVER VALLEY WILL
ENHANCE LOW LEVEL DIRECTIONAL SHEAR. MAIN SEVERE THREATS WILL BE
LARGE HAIL OR ISOLD SVR WIND GUSTS.
