GEN TSTMS ARE FCST TO THE RIGHT OF A LINE FROM 30 NNE CLM 25 N OLM
25 SSW PDX 35 NNE OTH 30 W OTH.

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THE LARGE SCALE PATTERN IS BECOMING MORE PROGRESSIVE AS A DEEP
TROUGH MOVES E OF NEW ENGLAND. AN UPSTREAM RIDGE DEVELOPS FROM
THE PLAINS TO THE MS VALLEY...AND A BROAD TROUGH REMAINS OVER THE
WESTERN STATES. THE SHORTWAVE TROUGH OVER NRN CO THIS AFTERNOON
WILL EJECT NEWD TO THE UPPER MS VALLEY TONIGHT AND GRADUALLY
WEAKEN. MEANWHILE...ANOTHER SHORTWAVE TROUGH JUST WEST OF WA/OREGON
WILL MOVE INLAND OVER WA/ORE LATER THIS EVENING.

VERY WEAK MID LEVEL BUOYANCY EXISTS IN ASSOCIATION WITH THE NRN CO
TROUGH...AS WELL AS OVER OK/TX WITH A SRN STREAM TROUGH THAT IS
MOVING NEWD. STILL...THE ENVIRONMENT WILL BECOME LESS FAVORABLE FOR
THUNDERSTORMS WITH TIME AS BOTH SYSTEMS MOVE AWAY FROM THEIR
ORIGINAL MID LEVEL MOISTURE SOURCES.

SATELLITE IMAGERY AND NATIONAL LIGHTNING DATA REVEAL SOME
CONVECTION/VERY ISOLATED LIGHTNING STRIKES IN ASSOCIATION WITH THE
TROUGH APPROACHING THE PAC NW COAST. THIS SYSTEM WILL WEAKEN AS IT
MOVES ONSHORE, BUT AS COLDER AIR IN THE MID AND UPPER LEVELS MOVE
ONSHORE THE LAPSE RATES WILL STEEPEN AND ISOLATED THUNDERSTORMS WILL
STILL BE POSSIBLE THROUGH THE END OF THE PERIOD.
