...Rapid warm-up forecast across much of the Lower 48 today and
tomorrow...

Expansive high pressure will drive calm weather across much of the
Nation to open the work week, with most notable precipitation
relegated to the western face of the Olympic Range from a
weakening atmospheric river. Temperature wise, unseasonably mild
weather is in store for much of the Lower 48 today and tomorrow as
a zonal jet stream scours out lingering Polar air over the CONUS.
While much of the Nation will feel above average highs today and
tomorrow, warm weather fans across the Heartland will emerge as
the big winners with this warm-up and enjoy highs in the 50's and
60's -- nearly 25-30 degrees above average. The lone exception to
this warm stretch will fall along the Gulf Coast, which could
experience marginally freezing overnight temperatures beneath the
high pressure center. Cold air should eventually return east of
the Continental Divide beyond Tuesday behind a series of cold
fronts. A deepening low pressure center along these fronts also
will support additional wintry weather over the Upper Midwest and
Northeast, although through Wednesday morning impacts appear
minor.
