...Lingering showers and thunderstorms found across the East Coast and
Southeast today as a cold front exits the region...
...Unsettled weather enters the Pacific Northwest and Northern Great Basin
on Thursday night...
...Dry and unseasonably warm temperatures continue in the West as cooler
temperatures spread into the East...
After an active stretch of weather in the central and eastern U.S., much
quieter conditions are in store for a majority of the Lower 48 through the
end of the week. A cold front that currently stretches from the Northeast
through the Ohio Valley and eventually into the western Gulf of Mexico is
expected to exit the East Coast this evening, while continuing to linger
across northern Florida on Thursday. Showers and thunderstorms will be
found along the frontal boundary up and down the East Coast. A few
thunderstorms could turn severe in the Mid-Atlantic and Southeast, with
isolated damaging wind gusts and large hail the primary concern. The Storm
Prediction Center has issued a Marginal Risk of severe thunderstorms that
extends from Delaware southwestward to the central Gulf Coast. The
slow-moving nature of the cold front across the central Gulf Coast could
lead to scattered instances of flash flooding today as well. WPC has
issued a Marginal Risk of Excessive Rainfall across this area, with a
small embedded Slight Risk that includes coastal regions of southeast
Mississippi, Alabama, and the western Florida Panhandle.
Elsewhere, a weak area of low pressure and associated cold front is
forecast to swing through the Central Plains today and into the Ohio
Valley by Thursday night. Only light showers and scattered thunderstorms
are expected, with light snow possibly mixing in across the Dakotas this
morning. For the Pacific Northwest, a fast moving cold front will produce
showers and high elevation light snow between Thursday night and Friday
morning, as well as the Northern Great Basin/Northern Rockies by Friday.
Temperature-wise, using Cinco de Mayo standards it will be quite spicy
throughout the West and very mild from the Midwest to Northeast through
Friday. High temperatures are forecast to soar 10 to 20 degrees above
average throughout much of the western U.S. today before the warm
temperatures shift into the Intermountain West on Thursday. A few daily
temperature records could be set in the San Joaquin Valley as highs reach
into the upper 90s. Shifting east, the current warm and humid airmass will
be short-lived across the Mid-Atlantic and Southeast this morning as
refreshing dry and cooler air enters by tonight. Thursday will feature
high temperatures nearly 10 degrees below average from the Midwest through
the Ohio/Tennessee valleys and into the Northeast.
