VALID 271200Z - 281200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
SLOW CHANGES ARE EXPECTED IN THE UPPER AIR PATTERN ON MON AS THE
GREENLAND BLOCK RETROGRADES.  THIS WILL ALLOW THE POLAR VORTEX TO
BEGIN SHEARING EWD AND RESULT IN A BUILDING RIDGE OVER MOST OF THE
CONUS. TO THE WEST...UPPER SYSTEM DROPPING SWD TO THE WEST OF 138W
WILL BEGIN TO EJECT NEWD ON MON...REACHING THE PAC NW AND NRN/CNTRL
CA BY 12Z TUE. WHILE MOST OF THE COUNTRY WILL REMAIN TSTM-FREE...A
FEW TSTMS ARE PSBL ACROSS PARTS OF CA. 

...CA...
TONGUE OF SUB-TROPICAL MSTR WILL ADVECT NEWD AHEAD OF THE EJECTING
ERN PAC TROUGH MON AND MON NIGHT.  RAIN WILL INCREASE LATE SUN NIGHT
ACROSS NRN/CNTRL CA WITHIN STRONG WARM ADVECTION REGIME AND
GRADUALLY SPREAD SWD.  A STRONGER BAND OF CONVECTION/ISOLD TSTMS
ASSOCIATED WITH THE COLD FRONT MAY DEVELOP OFFSHORE MON AFTN AND
QUICKLY MOVE ONSHORE NRN/CNTRL CA MON EVE/NIGHT.  VERY STRONG WIND
FIELDS /SLY 55 KT AT H85 BENEATH SWLY 90 KT AT H5/ WILL ACCOMPANY
THE PARENT UPPER TROUGH.  THUS...THERE IS SOME CONCERN THAT STRONGER
STORMS ALONG THE FRONT MAY TEND TO BOW AND PRODUCE DAMAGING WINDS. 
LAPSE RATES... HOWEVER...ARE WEAK AND DO NOT STEEPEN UNTIL LATER MON
NIGHT IN THE POST-FRONTAL REGIME.  THUS...ATTM...WILL MAINTAIN A NO
SEVERE FORECAST.
