...Active weather expected with a Pacific system dropping through the
Central Great Basin and Southwest...
...An arctic front slowing down while dropping out of the north central
U.S. will bring unsettled weather from the Southern Plains to the
Northeast and set up quite the dichotomy of temperature anomalies...
...Widespread moderate to heavy precipitation will move onshore with a warm front surging into the Pacific Northwest Friday into Saturday...
Unsettled weather will continue with a Pacific front sinking through the
southwestern corner of the Nation late this week.
Accumulating snows will be possible over the higher elevations of the Central Great Basin and Sierra Nevada range...and as increasing amounts of Pacific moisture get wrapped into the system... widespread moderate to heavy precipitation is expected to develop over the Southwest.
Falling temperatures across the region will make snow a possibility over portions of the Mogollon Rim.
Strong winds with an arctic front dropping out of the north central U.S.
will continue to force upslope snows over the Northern to Central Rockies and adjacent High Plains on Thursday.
Farther east...while the front pushes through the Midwest and Central Plains...a lack of moisture will initially limit precipitation; However...as the boundary slows down and warm moist Gulf air surges northward ...weather will become increasingly active along the front.
A wintry mix of snow and freezing rain will be possible to the north and west of a surface low tracking northeastward along the boundary ...impacting portions of the Middle Mississippi Valley...Great Lakes...a nd interior New England.
Heavy rains will be the main concern from the Central Plains to the Lower Mississippi Valley as showers and thunderstorms breakout ahead of the southern portion of the boundary.
Also...temperatures 15 to 20 degrees above normal ahead of the front and 15 to 20 degrees below normal behind the boundary will set up quite the dichotomy of temperatures across the Central and Eastern U.S..
A warm front moving onshore will bring moderate to heavy precipitation into the Northwestern U.S. Friday into Saturday.
Steady rains are expected along the Washington and Oregon coasts ... and widespread snowfall accumulations will be possible over the Cascades...Intermountain West...and Northern Rockies.
