Detailed Summary:

A lingering Arctic airmass over portions of the central and eastern U.S. will begin to moderate 
this weekend. However another surge of cold air will settle into the Lower Great Lakes and 
Northeast regions. These areas will are expected to have much below normal temperatures, with a few 
locations possible setting new records. Passage of the leading cold front may also bring a period 
of gusty winds from the High Plains to the western Gulf Coast early in the period, but wind 
speeds/gusts at this point do not appear to meet criteria for a high wind area on the hazard chart. 
Locally heavy rainfall will be possible along the immediate Gulf Coast, however the heaviest 
amounts will likely remain offshore. Model guidance is indicating that a nor'ester will spin up 
near the Carolinas and will keep the possibility of heavy rain along the Carolinas/Mid-Atlantic 
Coasts possible through the end of the forecast period, Nov 18. 

Recent warmer than average temperatures across the North Slope will return to normal by Nov 14. 
Portions of southern Mainland will have rain/elevated snow as an initial surface low moves through 
the Gulf of Alaska, though amounts may not reach criteria for a heavy rainfall area. Across the 
Aleutians/western Peninsula region, the guidance continues to show the approach of a deep cyclone 
which could deliver a period of high winds and waves to portions of the Panhandle region, however 
it has trended south which would prevent it from reaching criteria. Temperatures will begin to 
climb from midweek onward across the North Slope. The criteria for well above normal temperatures 
will be met by Nov 18.
