A front extending from the Upper Mississippi Valley southward to the
Southern High Plains will move eastward to the Great Lakes to the Lower
Mississippi Valley by Friday. Moisture will pool along the boundary
aiding in the development of showers and thunderstorms over the Middle
Mississippi Valley that will expand southward into the Southern Plains by
Thursday morning. The showers and thunderstorms will also expand
northward into the Upper Great Lakes by Thursday evening, with heavy rain.
By Friday morning the showers and thunderstorms will extend from the
Great Lakes southward to the Lower Mississippi Valley/Central Gulf Coast,
with moderate rain. In addition, rain will develop over parts of the
Upper Great Lakes on Wednesday evening that will move into Southern Canada
by Friday morning.
Meanwhile, upper-level energy will aid in producing moderate to heavy rain
over parts of the Central High Plains on Wednesday evening moving into the
Central Plains by Thursday while the intensity weakens to light to
moderate rain. Rain and snow will develop over parts of the higher
elevations of the Central Rockies on Wednesday evening.
Additional upper-level energy will enter the Northern Tier State and move
southeastward to the Upper Mississippi Valley/Central Plains by Friday.
The energy will aid in developing rain and snow over parts of the Northern
High Plains/Northern Rockies on Thursday morning that will move to parts
of the Northern Plains by Friday. Furthermore, rain will also develop
over parts of the Northern High Plains and move eastward to the Upper
Mississippi Valley by Thursday. Elsewhere, low pressure off New England
Coast will produce moderate to heavy rain over parts of New England Coast
on Wednesday evening that will slowly wane overnight ending on Thursday.
