LATEST WATER VAPOR IMAGERY SHOWS TWO UPPER-LEVEL TROUGHS IN PLACE
ACROSS THE CONUS.  THE FIRST TROUGH IS ASSOCIATED WITH A CLOSED LOW
LOCATED JUST OFF THE COAST OF MARYLAND. STRONG ASCENT AND COLD AIR
ALOFT WITH THE UPPER-LOW MAY BE ENOUGH TO SUPPORT ISOLATED
THUNDERSTORM DEVELOPMENT MAINLY IN THE COASTAL WATERS OFF OF SRN NEW
ENGLAND. THE SECOND UPPER TROUGH EXTENDS WWD FROM THE NRN HIGH
PLAINS INTO THE PACIFIC NORTHWEST. A FEW THUNDERSTORMS MAY FORM
ALONG THE COASTAL SECTIONS OF WA THIS EVENING AS A SECONDARY
UPPER-LEVEL IMPULSE MOVES INLAND. NO SEVERE THREAT IS ANTICIPATED
ACROSS THE CONUS THROUGH THE DAY 1 PERIOD.
