...NRN PLAINS...
AN UPPER-TROUGH CURRENTLY OFF THE PACIFIC NW COAST WILL DRIFT EWD

FORECAST SOUNDINGS ACROSS THE REGION 21Z THURSDAY SHOW MODERATE DEEP
LAYER SHEAR WITH SBCAPE VALUES ABOVE 2000 J/KG. THIS SHOULD BE
SUFFICIENT FOR SUPERCELLS IF STORMS REMAIN DISCRETE. INVERTED
V-SOUNDING PROFILES SUGGEST A MARGINAL WIND DAMAGE POTENTIAL THREAT
MAY EXIST LATE THURSDAY AFTERNOON AND EARLY EVENING. HAIL WILL ALSO
BE POSSIBLE WITH THE STRONGER CELLS AS CONVECTION EXPANDS IN
COVERAGE DURING THE EVENING AND MOVES EWD INTO NW MN. PARTS OF THE
NRN PLAINS MAY NEED TO BE UPGRADED TO SLIGHT RISK IN LATER OUTLOOKS.


...NRN NEW ENGLAND...
AN UPPER-TROUGH IN CNTRL CANADA WILL SLIDE ESEWD ACROSS ONTARIO
WEDNESDAY NIGHT INTO NEW ENGLAND THURSDAY. LIFT AHEAD OF THE TROUGH
SHOULD RESULT IN SCATTERED STORMS BY THURSDAY AFTERNOON. MODELS
FORECAST SUFFICIENT INSTABILITY FOR STRONG UPDRAFTS WITH ABOUT 30 KT
OF DEEP LAYER SHEAR. THIS MAY BE ENOUGH SHEAR FOR MARGINALLY SEVERE
MULTICELL STORMS MAINLY DURING THE AFTERNOON NEAR PEAK HEATING.
