...Blizzard conditions possible with bombogenesis off the Northeast
...Widespread precipitation expected with a Pacific front moving inland
over the western U.S....
...Shower and thunderstorm activity will be on the increase across Texas...
Another Arctic high sliding down from western Canada and moving in over the central and eastern U.S. will keep temperatures well below normal across several locations east of the Rockies early this week.
In addition to the cold...light snows will be possible with energy embedded in the flow aloft...which is expected to swing through the Middle/Upper Mississippi Valley Monday evening and into the northern Mid-Atlantic region by Tuesday morning.
Showers and thunderstorms will continue to develop to the north of a
frontal boundary stalled out over the northern Gulf of Mexico Monday
evening...at the leading edge of an initial shot of cold air that plunged
through the central and eastern U.S. this past weekend.
A surface low developing along the front will steadily track northeastward away from Florida's Atlantic Coast Monday night into Tuesday...and precipitation across the southern tier should lift northward across the Southeast and Mid-Atlantic states.
As the low continues its track up the Eastern Seaboard on Tuesday...the combination of the energy aloft swinging through the Mid-Atlantic region and a strong temperature gradient at the surface
will allow the storm to undergo rapid cyclogenesis...or bomb out.
By the Wednesday morning...a 960 MB surface low is expected off the New England coast...which would be a 48 MB drop in 24 hours.
The low should track far enough offshore to keep precipitation confined to the coast. However; the combination of snow and the strong winds surrounding the deep cyclone could lead to blizzard conditions for some of the coastal areas of New England.
Widespread precipitation is expected with a Pacific front moving inland over the Western U.S. early this week. Initially...the majority of
precipitation will fall as snow...but as temperatures and snow levels drop behind the front...accumulating snows will be possible along the higher elevations of the Cascades...Sierra Nevada...and Central / Northern Rockies.
Shower and thunderstorm activity will be on the rise across Texas on
Tuesday night into Wednesday as a piece of southern stream energy lifts through aloft and moisture increases across the region from return flow from the western Gulf.
