...Snow over the southern Rockies/High Plains will spread toward Oklahoma
tonight...

...Large temperature swings across the northern U.S. as arctic air
moderate slowly over the eastern and southern U.S....

...A low pressure wave will bring some showers and possibly thunderstorms
across southern Florida today and into Thursday...

An upper level trough digging southward into the southern Rockies will
continue to bring a good chance of snow across the northern half of New
Mexico this morning before swinging eastward across the Texas Panhandle
and into Oklahoma later today into tonight.  Much of these areas should
receive 1 to 3 inches of snow, although snow bands may lead to localized
higher amounts.  This area of snow should gradually taper off as the upper
level trough weakens and tracks east toward the mid-Mississippi Valley
Wednesday night.

Caught in between mild air that builds up over the High Plains and a pair
of arctic cold fronts forecast to plunge from Canada, the northern tier
states will experience large temperature swings through the next couple of
days.  Frigid conditions across the upper Midwest this morning will be
quickly followed by milder than normal conditions by Thursday before
another arctic surge reaches the area Thursday night.  Mainly light snow
is expected to accompany the arctic front as it sweeps through the Great
Lakes on Thursday.  Meanwhile, arctic air that has settled across the
eastern and southern U.S. will moderate slowly during the next couple of
days.

Elsewhere, a low pressure wave will bring some showers and possibly
thunderstorms across southern Florida today and into Thursday.  This wave
is forecast to become nearly stationary just east of Florida through
Friday morning, with rain chances gradually decreasing over Florida.  For
the West, dry and mostly quiet weather is anticipated.  In contrast, rain
chances are forecast to increase across southern Texas Thursday night as
another upper level impulse dipping through the Rockies interacts with a
developing frontal boundary.
