WEATHER SATURDAY APRIL 20 2024...SEVERE WEATHER FROM TEXAS TO GEORGIA ...FAIR IN NEW YORK AND LA RAIN PAC NW

There is a Slight Risk of excessive rainfall over parts of the Southern
Plains/Lower Mississippi Valley on Saturday.
Light to moderate snow over parts of the Central Rockies and Central
High Plains overnight Friday into Saturday and a second area of light snow
over the Cascades and Northern Intermountain Region on Sunday.
Strong to severe thunderstorms from the southern Mid-Atlantic,
Southeast to the Southern Plains on Friday and Saturday.
A front extending from Upstate New York southward to the Mid-Atlantic and
then westward to the Western Gulf Coast will move off the Northeast and
Mid-Atlantic Coast by Saturday afternoon. The boundary lingers along the
Gulf of Mexico Coast through Sunday evening. As the front moves into the
southern Mid-Atlantic/Southeast, showers with strong to severe
thunderstorms will develop over the area. Therefore, the SPC has issued a
Marginal Risk (level 1/5) of severe thunderstorms over parts of the
Mid-Atlantic/Southeast through Saturday morning. The hazards associated
with these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes. The area of showers and
thunderstorms will extend into parts of the Lower Mississippi Valley and
the Southern Plains through Friday night. Moreover, rain will develop over
parts of the Northeast Friday night into Saturday as light snow showers
develop over parts of the Upper Great Lakes, ending by Saturday afternoon.
Overnight Friday into Saturday, upper-level energy and upslope flow
associated with strong high pressure over the Northern High Plains will
help produce light to moderate snow over parts of the Central Rockies and
Central High Plains.
On Saturday, as the front settles over the Gulf Coast, showers with strong
to severe thunderstorms will develop over parts of the Southern Plains and
Southeast. Therefore, the SPC has issued a Marginal Risk (level 1/5) of
severe thunderstorms over two areas, the Southern Plains/Western Gulf
Coast and the second area over the Southeast from Saturday into Sunday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a minimal threat of
tornadoes. The showers and thunderstorms will also produce heavy rain over
parts of the Southern Plains/Lower Mississippi Valley. Therefore, the WPC
has issued a Slight Risk (level 2/4) of excessive rainfall with these
thunderstorms. The associated heavy rain will create mainly localized
areas of flash flooding, with urban areas, roads, and small streams the
most vulnerable. On Sunday, the strong to severe thunderstorm threat has
come to an end.
However, showers and thunderstorms will continue over parts of the
Southeast to the Southern Plains. Meanwhile, a front will come onshore
over the Pacific Northwest Saturday afternoon and move eastward to the
Northern High Plains and Great Basin by Sunday evening. The system will
produce rain over parts of the Pacific Northwest Coast through Sunday
evening. Furthermore, overnight Saturday, light snow will develop over the
Cascades and parts of the Northern Intermountain Region by early Sunday
morning, continuing into Sunday evening.
