...Heavy rain possible from parts of the Southern Plains to the Southern
Ohio/Tennessee Valleys...
...Heavy snow possible over parts of the Northern/Central Rockies...
A front extending from the Great Lakes southward to Central Gulf Coast
will move eastward to the Northeast while weakening by Friday morning.
Showers and thunderstorms will develop along and ahead of the front,
likewise, from the Great Lakes to the Central Gulf Coast that will also
move eastward to off the Northeast/Mid-Atlantic Coast by Friday afternoon.
Snow will develop over parts of the Upper Mississippi Valley into parts
of the Upper Great Lakes ending by Friday morning. Rain/freezing rain
will also develop over parts of the western portion of the Upper Peninsula
of Michigan through Thursday evening.
Meanwhile, another front over Northern Rockies to the Great Basin will
move southeastward and link up with the aforementioned boundary over the
Eastern U. S. on Thursday evening over the Southern Plains into the
Central Gulf Coast. The front will lift northward into the Middle
Mississippi Valley/Western Ohio Valley by Friday evening. In addition,
energy rotating around an upper-level low over James Bay will induce a
reinforcing front over the Great Lakes on Friday evening, too. The system
will produce snow and lower elevation rain over the Northern/Central
Rockies on Thursday that will continue over the region through Friday
evening. As the storm moves southeastward to the Southern High Plains,
showers and thunderstorms will develop over parts of the Central/Southern
High Plains on Thursday afternoon that will expand eastward to the Middle
Mississippi Valley by Friday morning and into parts of the Ohio Valley by
Friday evening. Additionally, showers and thunderstorms will develop over
the Lower Mississippi Valley and the Tennessee Valley on Friday afternoon
into evening. Furthermore, additional upper-level energy will move into
the Great Basin/Southwest/Southern Rockies on Friday. The energy will
produce rain and higher elevation snow over parts of the Southern
Rockies/Southwest on Friday into Friday evening.
Elsewhere, onshore flow will aid in producing rain and higher elevation
snow over parts of the Pacific Northwest on Thursday into early Friday
morning.
