   ...ERN ID/SRN MT/WY SSEWD TO THE CENTRAL HIGH PLAINS...
   HIGH BASED THUNDERSTORMS WILL CONTINUE TO DEVELOP OVER ERN ID/NWRN
   WY AND TRACK ESEWD ACROSS THIS REGION INTO THE EVENING.  WELL MIXED
   BOUNDARY LAYER AND MODERATE UNIDIRECTIONAL WIND FIELDS WILL BE
   FAVORABLE FOR DAMAGING MICROBURST WINDS.  ADDITIONAL SEVERE THREAT
   IS EXPECTED OVER THE CENTRAL HIGH PLAINS...WHERE A SIMILAR
   THERMODYNAMIC ENVIRONMENT FAVORS DAMAGING WIND GUSTS.   FOR
   ADDITIONAL INFORMATION...PLEASE REFER TO SPC WW AND MESOSCALE
   DISCUSSIONS FOR THIS REGION.
   
   ...PREVIOUS OUTLOOK ISSUED AT 20Z...
   ...CNTRL/ERN NC...NRN SC AND SERN VA...
   A STRONG VORT MAX CONTINUES ESEWD THROUGH NC/VA. HIGHER LOW LEVEL
   MOISTURE HAS SHIFTED TO THE COAST NEAR THE INITIAL CONVERGENCE
   BAND. HOWEVER...RESIDUAL DEWPOINTS IN THE UPPER 50S AND SURFACE
   HEATING UNDERNEATH COLD AIR ALOFT IS SUPPORTING MLCAPES TO 1500
   J/KG. STRONGER MID LEVEL FLOW WILL SHIFT SEWD...RESULTING IN
   DECREASING DEEP LAYER SHEAR PROFILES WITH TIME. HOWEVER...THE
   THERMODYNAMIC PROFILES WITH COLD AIR ALOFT...LOW WET BULB ZERO 
   LEVELS AND MODERATE INSTABILITY MAY PROVE SUFFICIENT FOR ISOLATED
   STORMS TO PRODUCE LARGE HAIL. ALSO...DESPITE BEING IN A DECREASING
   TREND...DEEP SHEAR MAY REMAIN AT LEAST MARGINALLY FAVORABLE FOR MID
   LEVEL UPDRAFT ROTATION OVER THE ERN PARTS OF NC/SC...WHICH WOULD
   FURTHER ENHANCE POTENTIAL FOR LARGE HAIL. ISOLATED DAMAGING WIND
   GUSTS MAY ALSO BE POSSIBLE GIVEN 25+ LOW LEVEL TEMPERATURE/DEWPOINT
   SPREADS. 
   
   ...ERN PARTS OF THE NRN PLAINS THROUGH UPPER/MID MS VALLEY... 
   SCATTERED STORMS ARE CURRENTLY DEVELOPING OVER ERN PARTS OF SD INTO
   NERN NE AND NWRN ID WITHIN ZONE OF WARM ADVECTION ALONG SWLY LOW
   LEVEL JET. THESE STORMS APPEAR ELEVATED AND ROOTED ABOVE 3 KM. THE
   ATMOSPHERE SW OF THIS ACTIVITY CONTINUES TO WARM AND DESTABILIZE
   BUT REMAINS CAPPED. HOWEVER...THE LOW LEVEL JET WILL CONTINUE TO
   STRENGTHEN INTO THE EVENING IN RESPONSE TO APPROACHING EXIT REGION
   OF SEWD MOVING UPPER JET. STORMS MAY INCREASE IN COVERAGE/INTENSITY
   IN THE ZONE OF WARM ADVECTION AS THE LOW LEVEL JET STRENGTHENS AND
   TRANSPORTS INCREASINGLY HIGH THETA-E AIR EWD FROM THE DESTABILIZING
   WARM SECTOR. IT APPEARS THE STORMS MAY REMAIN ELEVATED. HOWEVER...
   SUFFICIENT CLOUD LAYER SHEAR WILL BE PRESENT TO SUPPORT UPDRAFT
   ROTATION WHICH ALONG WITH STEEP LAPSE RATES AND MODERATE
   INSTABILITY SUGGEST THREAT FOR LARGE HAIL. ALSO...THE BOUNDARY
   APPEARS DRY ENOUGH FOR A DAMAGING WIND THREAT...ESPECIALLY IF
   STORMS CAN ORGANIZE INTO AN MCS AS THEY DEVELOP SEWD.
   
   ...NRN CA AND NV THROUGH OR...
   LARGE SCALE ASCENT/UPPER DIVERGENCE DOWNSTREAM FROM SHORTWAVE
   TROUGH MOVING NWD INTO CA/OR SHOULD PROVIDE A FAVORABLE ENVIRONMENT
   FOR STORMS TO DEVELOP OVER THE HIGHER TERRAIN OF NRN CA/OR/NRN NEV.
   STRONG SURFACE HEATING IS OCCURING OVER THIS AREA AND IS
   CONTRIBUTING TO DESTABILIZATION. SUFFICIENT DEEP SHEAR EXISTS FOR
   HIGH BASED SUPERCELLS WITHIN AN ENVIRONMENT WITH DEEPLY MIXED
   INVERTED-V BOUNDARY LAYERS. DAMAGING WIND SHOULD BE THE MAIN THREAT
   THROUGH EVENING.
