   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE NRN ROCKIES

   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN GREAT
   LAKES... AND NEW ENGLAND STATES...
   
   ...HIGH PLAINS/NRN ROCKIES...
   
   A POSITIVELY TILTED UPPER-LEVEL TROUGH ACROSS THE PACIFIC NW WILL
   SHIFT SEWD INTO THE INTERMOUNTAIN WEST ON DAY 2. AS THE UPPER-TROUGH
   SHIFTS EWD...A SFC LOW WILL DEEPEN AND MOVE NEWD INTO THE NRN
   ROCKIES. THIS WILL RESULT IN LOW-LEVEL MOISTURE ADVECTION INTO WRN
   NEB...WY AND NE CO DURING THE DAY. A WEAK IMPULSE IS FORECAST BY THE
   ETA...ETAKF AND GFS TO EJECT NEWD OUT OF THE TROUGH INTO THE NRN
   HIGH PLAINS. THIS WILL PROVIDE SUFFICIENT LIFT FOR SCATTERED
   THUNDERSTORMS BY AFTERNOON. THE STORMS WILL DEVELOP NEAR A
   STATIONARY FRONT LOCATED FROM NW TO SE ACROSS ERN ID...SRN WY AND
   NRN CO. AS TEMPS WARM IN THE AFTERNOON...CONVECTION SHOULD INITIATE
   OVER THE HIGHER TERRAIN AND MOVE NEWD INTO THE HIGH PLAINS. FORECAST
   SOUNDINGS ACROSS THE REGION SHOW STRONG DIRECTIONAL SHEAR PROFILES
   CREATING 0-6 KM SHEAR VALUES OF 35 TO 45 KT...MORE THAN SUFFICIENT
   FOR SEVERE STORMS WITH SUPERCELLS LIKELY IN THE BETTER LOW-LEVEL
   MOISTURE ACROSS WY...NEB AND NE CO. STEEP MID-LEVEL LAPSE RATES AND
   INVERTED V-PROFILES SUGGEST A THREAT WILL EXIST FOR LARGE HAIL AND
   DAMAGING WINDS. ALTHOUGH SUPERCELLS DEVELOPMENT SHOULD BE
   ISOLATED...THE SEVERE THREAT SHOULD CONTINUE INTO THE EVENING HOURS
   AS THE STORMS SPREAD NEWD.
   
   
   ...SRN GREAT LAKES/NEW ENGLAND STATES...
   
   A COLD FRONT CURRENTLY IN ONTARIO AND QUEBEC WILL MOVE SEWD TONIGHT
   AND BECOME QUASI-STATIONARY ON DAY2...EXTENDING EAST TO WEST FROM
   NRN IA ACROSS THE CHICAGO AREA INTO LOWER MI AND NRN NY. ALTHOUGH
   LARGE-SCALE ASCENT SHOULD BE WEAK ACROSS THE REGION...THE FRONTAL
   BOUNDARY WILL PROVIDE THE LOW-LEVEL CONVERGENCE NECESSARY FOR
   CONVECTIVE INITIATION AS TEMPS WARM AND THE ATMOSPHERE DESTABILIZES
   WEDNESDAY AFTERNOON. FORECAST SOUNDINGS FOR WEDNESDAY AFTERNOON
   ALONG THE FRONTAL BOUNDARY...SHOW UNIDIRECTIONAL SHEAR WITH
   RELATIVELY WEAK MID-LEVEL FLOW. HOWEVER...0-6 KM SHEAR VALUES ARE
   FORECAST TO RANGE FROM 20 TO 30 KT WHICH STILL SHOULD BE SUFFICIENT
   FOR MULTICELL SEVERE STORMS. ALTHOUGH HAIL WILL BE POSSIBLE WITH THE
   STRONGEST UPDRAFTS...WIND DAMAGE SHOULD BE THE PRIMARY THREAT
   CONSIDERING THE LOW-LEVEL JET WILL BE POSITIONED FROM EAST TO WEST
   ALONG AND AHEAD OF THE STATIONARY FRONT. THE STORMS SHOULD MOVE SEWD
   AWAY FROM THE FRONTAL BOUNDARY DURING THE LATE AFTERNOON WITH THE
   GREATEST SEVERE THREAT OCCURRING NEAR AND JUST AFTER PEAK HEATING.
   STABILIZATION WILL ALLOW THE SEVERE THREAT TO SLOWLY DIMINISH DURING
   THE EVENING.
