Significant rainfall and mountain snow expected for the Pacific Northwest through Saturday… …Heavy rainfall likely this weekend and beyond for parts of the Gulf Coast, Florida, and into the Southeast…
A steady stream of moisture directed at the Pacific Northwest coastline will result in a variety of weather hazards into the weekend. An extended period of heavy rainfall and mountain snows is likely lasting through Saturday across portions of western Washington and Oregon. Along the coast, rainfall totals of several inches is expected, while in the highest elevations of the Cascades, snow accumulations may exceed 3 feet. The storm will also bring periods of high wind and rough surf to the coast. The system shifts slowly southward with heavy rain and mountain snows moving into portions of northern California by late Saturday into Sunday.
An upper level low crossing the southern Plains on Friday should reach the Gulf Coast by Saturday night. This will eventually spin up a low pressure system in the Gulf of Mexico which should move slowly northeastward towards the Florida Panhandle through early Sunday. Showers and thunderstorms, with heavy rainfall likely, will begin impacting the central Gulf Coast region on Saturday, which should spread into parts of the Southeast and northern Florida by Sunday. Gusty winds are also possible along the Gulf Coast on Sunday associated with this system.
Much of the Gulf Coast states to the East Coast and New England will be near or below average to start the weekend. The greatest anomalies are expected across interior New England where daytime highs could be 10 to 20 degrees below normal on Friday. In contrast, warmer than average temperatures will spread across the northern and central Plains into the Midwest where daytime highs on Saturday may be 10 to 20 degrees above normal for this time of the year. The West Coast should trend cooler through the weekend as a front moves inland late in the period.
