...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.
