NWS Weather Prediction Center College Park MD
426 PM EDT Wed Oct 28 2020
 
Valid Saturday October 31 2020 - Wednesday November 04 2020
 
Hazards:
- Flooding possible across portions of the Middle Mississippi Valley.
- Flooding likely across portions of the Middle Mississippi Valley.
- Heavy precipitation across portions of the Alaska Panhandle, Sat-Sun, Oct 31-Nov 1.
- Much below normal temperatures across portions of the Alaska Panhandle and mainland Alaska, 
Sat-Tue, Oct 31-Nov 3.
 
Detailed Summary:

The medium range period (Saturday, October 31st - Wednesday, November 4th) will feature no 
significant weather hazards over the CONUS, but will include heavy precipitation and much below 
average temperatures over parts of Alaska. A Severe drought is forecast to continue across much of 
the West and parts of the Northeast. An upper-level trough that will track across Canada this 
weekend is expected to generate rain and mixed precipitation over parts of the Lower Great Lakes 
and Northeast, but amounts are unlikely to be hazardous. Potentially heavy precipitation could 
impact the Pacific Northwest next week as a low pressure system emerges from the Alaskan Panhandle, 
but a hazard area is not warranted at this time.

The aforementioned low pressure system is forecast to produce heavy precipitation over the Alaskan 
Panhandle this weekend before spreading moisture down the North American coast into the beginning 
of next week. High pressure will build over mainland Alaska behind the previous system. This cold 
air mass will plunge temperatures to over 20 degrees below normal from Saturday through Tuesday.
