Detailed Summary:

The medium range period (Monday, November 2nd - Friday, November 6th) will be very quiet across 
much of the CONUS, while more active over Alaska. A closed upper-level low will generate heavy 
precipitation across the Alaskan Peninsula on Monday and Tuesday. High pressure will build in 
behind this system, ushering in, colder, much below normal temperatures across the southeastern 
part of mainland Alaska through Thursday, and the northern panhandle from Tuesday through Friday. A 
weak upper-level ridge will build over the northern mainland on Sunday leading to much above normal 
temperatures across the region on Monday. The ridge will gradually weaken over the next couple of 
days, despite temperatures remaining warmer than average, before a stronger--much more 
amplified--ridge arrives on Friday. This will lead to yet another day of much above normal 
temperatures over the northern mainland of Alaska.

Meanwhile over the CONUS, there remains the potential for heavy precipitation for the Pacific 
Northwest at the beginning of next week as the system that is forecast to impact the Alaskan 
Panhandle dives down into the Pac NW. The precipitation looks like it'll be relegated to just 
high-elevation snowfall at this time. Elsewhere, a cold and dry airmass will enter the eastern half 
of the country at the beginning of next week. This may lead to some isolated pockets in the 
Carolinas and the Southeast experiencing their first freeze of the season. Severe drought 
conditions will persist for much of the western United States, and parts of the Northeast 
throughout the medium range period.
