Valid 030100Z - 031200Z


Isolated, non-severe thunderstorms will remain possible along the
Pacific Northwest coast tonight.

...01Z Update...
Secondary strong 500mb speed max is digging southeast toward the OR
Coast. Very cold mid-level temperatures, which have steepened lapse
rates across the Pacific Northwest, are noted along the cyclonic
side of this feature. 00z soundings from UIL and SLE exhibit 500mb
temperatures around -33C with surface-6km lapse rates around 7.5-8
C/km. While lightning has been sparse with low-topped convection, a
few flashes have been noted along the southwest WA Coast around 23z.
Earlier thoughts regarding the possibility for a few weak
thunderstorms remain.
