...A low pressure system will bring strong to severe thunderstorms from
the central Plains eastward toward the central/southern Appalachians into
Friday...
...The same low pressure system will bring moderate to heavy rain for
parts of the Northeast and possibly severe thunderstorms for the
Mid-Atlantic by the Memorial Day weekend...
A developing low pressure system currently in the central High Plains will
be the main weather maker for the central and eastern U.S. as we head into
the Memorial Day weekend. Showers and thunderstorms will generally expand
eastward into the Midwest today ahead of the low pressure center while
additional thunderstorms are expected to organize across the central
Plains today ahead of a cold front. Some of these thunderstorms are
expected to become severe. In addition, heavy downpours from the
thunderstorms could result in flash flooding. Much of the rain and
thunderstorms will be moving across the lower Great Lakes, Midwest, Ohio
and Mid-Mississippi Valleys, and toward northeastern Texas on Friday. By
later on Friday, the low pressure system is forecast to move across the
central Appalachians. Thunderstorms developing over the Mid-Atlantic
could become severe Friday night. Meanwhile, moderate to heavy rain is
forecast to develop across southern New England early on Saturday as a new
low pressure center is forecast to form off Long Island. Across the Deep
South, scattered thunderstorms will move slowly southward toward the Gulf
Coast in association with the cold front later on Friday into the Memorial
Day weekend.
Across the Northeast, cooler air behind a cold front will settle into the
area today. Much of the northern Great Plains into the Midwest will have
cool afternoons due to clouds and rain tracking to the north of the
developing low pressure system. In fact, parts of North Dakota could see
some wet snow early this morning.
Out in the Pacific Northwest, a low pressure system moving onshore
Thursday morning will bring widespread rain to the area. Mixed
precipitation and even some wet snow is possible in the northern Cascades.
As the system moves inland, mixed precipitation is expected for the
northern Rockies early on Friday. By Friday night into Saturday morning,
showers and some thunderstorms are forecast to move across the northern
Plains ahead of a front, while a new low pressure center is forecast to
develop in the central High Plains.
