..SYNOPSIS
A MID-LEVEL TROUGH WILL TRAVERSE THE MIDWEST/GREAT LAKES REGIONS AS
UPPER RIDGING REMAINS IN PLACE OVER THE INTERIOR WEST, BUT WITH A
SMALL BUT PRONOUNCED MID-LEVEL IMPULSE IMPINGING ON THE NORTHERN
CALIFORNIA COASTLINE TODAY. THIS IMPULSE, IN TANDEM WITH ADEQUATE
INSTABILITY, WILL PROVIDE ENOUGH LIFT TO SUPPORT AT LEAST SCATTERED
THUNDERSTORMS TO PORTIONS OF THE PACIFIC NORTHWEST THIS AFTERNOON
INTO THE OVERNIGHT HOURS. THESE STORMS WILL MOVE ATOP A MODESTLY DRY
BOUNDARY LAYER, WITH WET AND DRY STORM MODES BOTH POSSIBLE.
NONETHELESS, THESE STORMS WILL OVERSPREAD DRY FUEL BEDS, ESPECIALLY
FROM THE CENTRAL/NORTHERN CASCADES AND POINTS EAST. DRY THUNDERSTORM
HIGHLIGHTS REMAIN IN PLACE FOR THE POSSIBILITY OF LIGHTNING STRIKES
(SOME DRY) POSING A HAZARD FOR FUEL IGNITION.
