Valley, while much above average temperatures spread across the West...

...Rains from Ian to push northward into South Florida on Monday...

The recent period of record high temperatures across the Central to
Southern Plains into the Lower Mississippi Valley will be coming to an end
in response to a southward moving cold front pushing across the Southern
Plains/Lower Mississippi Valley regions this weekend into early next week.
 This front is being driven by an increasingly amplified mid to upper
level pattern across the nation, with a deep trof stretching from eastern
Canada into the Northeast and a building upper ridge from the Southwest
into the Northern Rockies.  In addition to bringing cooler temperatures to
portions of the south, the above mentioned front will also spread below
average temperatures east southeastward from the Great Lakes into the Ohio
Valley Sunday and Monday, and across the remainder of the East by mid
week.  In the wake of this front moving through the Great Lakes, active
lake effect rain showers are likely Sunday into Monday downwind of all of
the Great Lakes as cold air will be moving over the warm lakes. 

While temperatures cool down across the east over the next few days, they
will be heating up across much of the West in response to the amplifying
upper ridge.  Much above average temperatures expected across most of the
West into next week, with a few record highs possible by Monday across the
coastal Pacific Northwest. 

The amplified upper trof stretching from eastern Canada into the East will
also help to draw Ian northwestward over the next few days from the
Caribbean toward western Cuba and eventually into the eastern Gulf of
Mexico.  Rainfall ahead of Ian may begin to affect South Florida on
Monday.  Additional impacts from Ian likely across Florida through much of
next week as the official storm track from the National Hurricane Center
pushes the storm northward through the eastern Gulf of Mexico.
