A slow-moving front across the Upper Great Lakes will produce showers and
thunderstorms over the region from Friday evening into Sunday.  The Storm
Prediction Center has issued a Slight Risk of severe thunderstorms over
portions of the region.  Tornadoes, large hail, and damaging winds are
possible across far northern Wisconsin into Upper Michigan late Friday
afternoon and evening.  Storms are expected to develop once again on
Saturday, with additional severe storms expected across northern Wisconsin.

Moisture and low pressure associated with the remnants of Tropical Cyclone
Beta continue to move across the Southeast, generating widespread showers
and some thunderstorms.  The Weather Prediction Center has issued a Slight
Risk of excessive rainfall over parts of the Carolinas through Saturday
morning.  The heavy rain associated with the showers and thunderstorms
will produce mainly localized areas of flash flooding over the area
through Saturday morning.  Scattered showers associated with Beta's
remnant moisture are possible in the Mid-Atlantic on Saturday.
Temperatures throughout the Southeast should also moderate to seasonally
mild levels on Saturday.

Elsewhere, temperatures will be 10 to 20 degrees above average over the
central and southern High Plains.  A strong cold front sweeping across the
Northwest is expected to usher in colder temperatures over the northern
and central High Plains.  Pacific moisture will also accompany this cold
front leading to periods of rain in the Pacific Northwest and northern
Rockies through Sunday morning. 

Red Flag Warnings are in effect for portions of California, the central
Rockies, and the northern and central Plains.  Critical fire weather
conditions are occuring now, or are imminent, across these areas.  Dry and
windy conditions are expected to contribute to elevated fire weather
concerns across portions of the western and central U.S. into the weekend.
 In addition there are air quality alerts over parts of the Central Valley
in California.
