...A wet and windy weekend is in store for the Pacific Northwest...
...Showers and thunderstorms will continue to moisten a cold front sweeping through the Central U.S....
A wet pattern will remain set up over the northwestern corner of the
Country this weekend due to a deep vortex spinning off the British
Vigorous energy rotating around the vortex will push a series of cold fronts and surges of moisture into the Pacific Northwest. The anomalous moisture will fuel widespread moderate to heavy rains across the region...with the heftiest totals expected along the favored slopes of the terrain. Enough moisture should spill inland to produce heavy rains over the Northern Rockies as well. In addition to the soaking rains...winds will become strong and gusty as the pressure gradient increases over the Northwest.
Showers and thunderstorms will continue to moisten a cold front
sweeping through the Central U.S. on Saturday.
On Sunday...the boundary should begin to weaken as its upper level support lifts farther northeastward into Canada. As a result... precipitation will become increasingly sparse while the weakening front presses through the Great Lakes and Ohio Valley.
However...enough moisture streaming out of the Western Gulf should continue to support convection along the southern portion of the boundary moving through the Lower Mississippi Valley and Southern Plains.
Strong surface ridging should keep much of the Eastern Seaboard
precipitation free during the short range period. However...low level
northeasterly flow off the Atlantic could bring some light shower activity
inland across Florida and up into the Carolinas.
