..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
ISOLATED THUNDERSTORMS WILL BE POSSIBLE ON FRIDAY ACROSS PARTS OF
THE PACIFIC NORTHWEST AND THE MIDWEST, BUT NO SEVERE THREAT IS
EXPECTED.
..SYNOPSIS
A PRONOUNCED, COUPLED MID-LEVEL/SURFACE TROUGH WILL TRAVERSE THE
MIDWEST INTO THE OH VALLEY AS A MID-LEVEL IMPULSE TRACKS FROM THE
PACIFIC NORTHWEST TO THE NORTHERN ROCKIES ON FRIDAY. SOME OF THE
LATEST GUIDANCE DEPICTS A PLUME OF COOLER TEMPERATURES ALOFT
ACCOMPANYING THE MIDWEST/OH VALLEY MID-LEVEL TROUGH, WHICH MAY
SUPPORT A FEW LIGHTNING FLASHES OVER THESE REGIONS FRIDAY INTO
FRIDAY NIGHT. LIKEWISE, COOLER TEMPERATURES ALOFT WILL OVERSPREAD
PORTIONS OF THE PACIFIC NORTHWEST INTO THE NORTHERN ROCKIES AS THIS
MID-LEVEL TROUGH PASSES OVERHEAD, PERHAPS RESULTING IN ENOUGH
BUOYANCY TO SUPPORT A FEW LIGHTNING FLASHES.
