Detailed Summary:

The medium range period (Sunday, January 23rd to Thursday, January 27th) will be relatively quiet 
across the lower 48 while Alaska's mainland Gulf Coast experiences an active period. The overall 
pattern will persist through the period as an upper-level ridge very slowly makes its way into the 
West Coast, and a series of short waves round an upper trough, centered around the Northwestern 
Passages of Canada, as they move through the Midwest and Northeast. Very cold air will arrive 
across the Deep South and East Coast behind a polar front associated with this Friday/Saturday's 
Mid-Atlantic/Southeast winter storm. High temperatures on Sunday will be between 15-25 degrees 
below normal for many of the aforementioned regions. High pressure will descend into the Northern 
Plains from Canada on Tuesday launching a cold front through the Central U.S.. This will allow for 
another shot of arctic air to invade the Northern Plains and Upper Midwest on Tuesday and 
Wednesday. High temperatures will be 20-30 degrees below average for many areas during this period. 
Much of the Northern and Central Plains will be warm through Monday before the arrival of the next 
cold front on Tuesday. The West remains seasonably warm under the upper-ridge. A piece of shortwave 
energy will break off from the mean flow across the CONUS, drop into the Southwest and develop into 
a cutoff low this weekend. This low may go on to produce heavy rainfall across the Gulf coast early 
next week, but too much uncertainty still exists as to whether the strongest rainfall will make it 
ashore.

...Alaska...

The active pattern continues along the mainland Gulf Coast of Alaska before quieting down a bit by 
next Tuesday. A low pressure system will spread heavy precipitation and high winds across the 
southern mainland coast of Alaska between Sunday and Monday before weakening and stalling out along 
the mainland/panhandle coasts. Much of the mainland will be seasonably warm through Tuesday before 
a cold front sweeps across the region and moderates temperatures.
