PREVIOUS DISCUSSION...

THE IR SAT IMG INDCT MSTLY CLDY BUT NO LIGHTNG STRIKES OVR THE
WTRS. THE RADAR HAS NO INDC OF TSTMS CELLS OVR THE REGION OR
WITHIN THE ADJ COASTAL AREAS THO IT SHOWS STRNG INLAND TSTMS CELLS
E AND NE OF THE CNTRL WTRS OVR NV. AT 0600Z WKNED HGH PRES NOW
1025 MB CNTRED 240 NM W OF WASH WTRSHAS A WEAK RIDGE ACRS THE WRN
PARTS FO THE REGION. INLAND LOW PRE 1005 MB OVR SRN CA HAS A TROF
XTNDG NW ACRS CNTRL CA STATE. THE PRES GRDNT IS TIGHTEST OVR THE
CNTRL REGION BUT NOT TIGHT ENOUGH TO GENERATE GALE FORCE WINDS.
THE MAX OBSVD WINDS ARE 20 KT OVR THE CNTRL WTRS AND THEY RANGE
BTWN 10 AND 20 KT ELSEWHERE.

MOST OF THE ERNGY IS CONFINED TO THE W OF THE UPPRLVL RIDGE THAT
LIES JUST W OF THE FCST REGION. THERE IS SOME ENRGY INLAND NR WASH
STATE BUT THAT WILL BE PUSHED SE INLAND. THE UPPRLVL RIDGE WILL
PERSIST AND THWART ANY EFFORTS OF ENERGY MANIFESTATION OVR THE
REGION THRU THE FCST PRD. SO SMOOTH WX TO CONTNE WITHOUT WRNGS OVR
THE FCST REGION.

THE GLBL MDLS HV CONTUNED TO INTIALIZE WELL WITH NO MJR DIFFS
AMONG THEM THRU THE FCST PRD. SO WILL JUST STAY WIH GFS MAINLY 10M
WINDS WITH JUST A SLIGHT ADJ BY UP TO 3 KTS MAINLY OVR THE CNTRL
REGION. IN THE SHORT TERM THE HGH PRES WILL SLIGHTLY SHIFT NW BUT
WILL STILL REMAIN W OF THE WASH WTRS WITH ABOUT THE SAME STRENGTH.
THE RIDGE WILL STLL CONTINUE W OF THE REGION WHILE THE INLAND TROF
WILL PERSIST BUT WEAKER AND SO THE PRES GRDNT OVR THE REGION SHUD
CONTINUE TO REMAIN SLACK INEVITABLY WINDS MUST ALSO REMAIN BELOW
GALE FORCE THRU THE FSCT PRD.
