.PREV DISCUSSION... /ISSUED 1003 AM CST MON FEB 14 2011/
DRY AND STABLE CONDITIONS ARE EXPECTED TO PRECLUDE ORGANIZED
THUNDERSTORMS OVER MOST OF THE CONUS TODAY...WITH THE EXCEPTION OF
THE PACIFIC NORTHWEST COAST.
A STRONG UPPER TROUGH IS EVIDENT ON WATER VAPOR IMAGERY OFF THE
WA/ORE COAST...AND SHOULD APPROACH THE COAST LATE TONIGHT.
STRENGTHENING ONSHORE FLOW AND COOLING MID LEVEL TEMPERATURES WILL
PROMOTE THE RISK OF SHOWERS AND A FEW THUNDERSTORMS IN
OROGRAPHICALLY FAVORED AREAS ALONG THE COAST RANGES...MAINLY LATE
TONIGHT. OFFSHORE LIGHTNING DATA HAS INDICATED ISOLATED ACTIVITY
THIS MORNING NEAR THE TROUGH AXIS...FURTHER INCREASING CONFIDENCE IN
THUNDERSTORM POTENTIAL LATER IN THE PERIOD.
