The cold fall weather pattern gripping much of the Lower 48 to the east of
the Rockies will begin to moderate by the end of the week and into the
weekend. The cold area of high pressure, currently centered from the Ohio
Valley into the Lower Mississippi Valley and Southern Plains will be
pushing eastward over the next few days and offshore of east coast on
Friday.  The much below average temperatures of Wednesday for all areas
east of the Rockies will remain below average Thursday into Friday, but
trend warmer on both days.  The coldest morning expected to be Thursday
morning when record low temperatures are possible from the Lower
Mississippi Valley, across portions of the Southeast, Mid-Atlantic and
northern New England.  Freeze warnings are in effect across all of these
areas, save for New England, signaling the end of the growing season for
these regions.   Most areas to the east of the Rockies will have below
freezing temperatures Thursday morning, except for the Gulf Coast, Florida
and the Southeast Coast.  In contrast to the below average temperatures to
the east of the Rockies, temperatures will remain above average over the
next few days from the Rockies to the West coast.

While most of the country will be dry over the next several days, a wet
weather pattern is beginning for portions of the west coast.  The initial
surge of above average moisture values from the first atmospheric river
event will bring a heavy precipitation threat into the Pacific Northwest
Wednesday night into early Thursday. This will be followed by additional
heavy precipitation late Friday into early Saturday for northern portions
of California.  This wet weather pattern should continue then into the
late weekend and next week with additional periods of heavy precipitation.
This upcoming wet weather pattern will be welcome across these regions as
much of the Pacific Northwest into Northern California has had below
average precipitation over the past month and is experiencing moderate to
extreme drought conditions.
