...Shower and thunderstorm chances stretch from the Upper Midwest and
Great Lakes to the Southern Plains over the next few days...

...Chilly and frosty start to Earth Day throughout the Ohio Valley and
Mid-Atlantic, while well above average temperatures remain in place across
much of the Southwest/Great Basin...

Precipitation chances are expected to remain mostly scattered and light
throughout much of the Nation into midweek as atmospheric moisture content
remains sparse following the passage of a strong cold front into the Gulf
of Mexico and western Atlantic. A few thunderstorms are possible across
the central and southern Florida Peninsula today as the aforementioned
cold front makes it's final exit. A few storms could turn severe and
produce damaging wind gusts and hail. Thus, the Storm Prediction Center
has issued a Marginal Risk (level 1/5) for severe weather across southeast
Florida. Otherwise, rain chances are forecast to progress eastward from
the northern Plains to the Upper Midwest today along a swiftly moving
Pacific cold front. By Tuesday, rain chances are anticipated to stretch
from the Great Lakes and Ohio Valley to the Southern Plains. The heaviest
rain associated with this system is possible across parts of
central/eastern Oklahoma and western Arkansas on Wednesday, but this
aspect of the forecast remains somewhat uncertain.

Temperatures are expected to start off in the 30s throughout much of the
Midwest, Ohio and Tennessee valleys, Mid-Atlantic, and Northeast as strong
high pressure leads to clear skies and cold temperatures at ground-level.
Lows into the low 30s are likely to lead to frost/freeze conditions and
has prompted Frost Advisories and Freeze Warnings for much of the region
where the growing season has already begun. Warmer weather is forecast to
begin spreading eastward on Tuesday, but will be short-lived as the next
shot of cold air enters the Great Lakes Tuesday night. Warmer weather is
anticipated to remain throughout the Southwest, Great Basin, and parts of
the Southern Plains through midweek. Highs can be expected to reach into
the 70s and 80s, with 90s and low 100s in the typical warm spots
throughout the Desert Southwest.
