...Rain and thunderstorms are forecast across the Gulf Coast states over
the next couple of days...

...Light snow and gusty winds are expected in the Great Lakes to Northeast
through tonight...

After a wet several days in the Tennessee and Ohio Valleys, rainfall there
will end this morning behind a cold frontal passage. For the first part of
the workweek, rain and thunderstorms are expected to focus across the Gulf
Coast states as moisture from the Gulf of Mexico streams into the region.
As a surface low pressure system moves eastward along a front, rain will
shift from eastern Texas and the Lower Mississippi Valley today and
tonight toward the Southeast on Tuesday. Rainfall amounts of 1 to locally
3 inches are forecast for these areas, and Marginal Risks of excessive
rainfall are in place, indicating isolated flash floods are possible. On
the back edge of the precipitation, light snow is possible for the
Southern Rockies/Southern High Plains early today. Then light snow or
mixed precipitation is possible for the Southern/Central Appalachians
Tuesday night into Wednesday.

Rain should also clear out of the Mid-Atlantic and Northeast today after
the cold front passes, but gusty westerly winds are likely behind the cold
front, prompting Wind Advisories for much of the region. Additionally,
snow is forecast to spread across the Great Lakes region and toward the
Northeast today into tonight. Snow amounts will generally be light, but
localized accumulations of a few inches are possible. Snow showers could
continue for the interior Northeast Tuesday, but should generally be
insignificant. Elsewhere, the rest of the U.S. should remain dry through
early Wednesday, with the exception of light precipitation in the Pacific
Northwest.

In terms of temperatures, the East Coast can expect warmer than average
conditions today, with daily records for warm minimum temperatures in
jeopardy this morning. Temperatures should then flip to cooler than
average across the East Coast on Tuesday (with the exception of the
Florida peninsula), along with a cooler than normal Southeast due to the
cloudiness and rain. The Southern High Plains will be cooler than normal
especially in terms of high temperatures today. Meanwhile, the
Northern/Central Plains can expect warmer than average temperatures,
particularly on Tuesday when highs could rise into the 50s and 60s.
