...Heavy snow possible for parts of the Upper Midwest and Upper Great Lakes on Friday...
The very vigorous upper level system which brought severe weather, heavy rain, and flash flooding to parts of the nations midsection yesterday and overnight will continue to push quickly eastward as the low pressure at the surface deepens and moves across the Upper Midwest/Great Lakes this morning.
Plenty of moisture and instability ahead of this system will result in widespread heavy rain and thunderstorms from the Lower Mississippi Valley to the Ohio Valley on Friday.
The Storm Prediction center has highlighted an area for a slight risk of severe weather for parts of the referenced area above.
The showers and thunderstorms will spread into the East Coast states by the afternoon and evening hours on Friday, but severe
weather and flooding rains are not expected to be much of a threat.
On Saturday evening, the southern portion of the front in the Gulf of Mexico is forecast to shift northward as a warm front which should increase the threat for heavy rain for parts of the Gulf Coast states overnight Saturday and into Sunday.
Elsewhere across the U.S., heavy snow on the north side of the
aforementioned system is expected to continue for parts of northern
Wisconsin and the Upper Peninsula of Michigan this morning, but should come to an end by nightfall as the surface low pushes into Southeast Canada.
On the southern edge of this colder air, some mixing of rain/snow or sleet/freezing rain will also be possible across the Upper Great Lakes.
Out west, a series of weak systems off the Pacific will keep scattered
rain and higher elevation snows in the forecast for much of the
Intermountain West and into the Rockies today and into the weekend.
