Reported by: 911 Call Center

The 911 Center relayed a report of water over a bridge on Lake Edmund Road, at the upper end of Rays Lake. Radar estimates indicate 5-6 inches of rain occurred over the area over a short period of time. The increased runoff caused the small lake to rise and inundate the low bridge.
A Colorado Low took shape during the early morning hours of Saturday, December 28th, with an inverted trough extending up toward the Red River Valley. During the day, the surface low tracked into eastern Nebraska, but the inverted trough remained over the valley. This allowed snow to spread slowly from the South Dakota border up to the highway 2 corridor. It was a very mild day, with high temperatures in the low 30s over southeast North Dakota and west central Minnesota, to the lower 20s in the Devils Lake region. Temperatures did not change much Saturday night, as the surface low tracked from eastern Nebraska up into north central Iowa. Meanwhile, the snow finally reached the Canadian border, and north to northeast winds continued to increase. From Sunday into Sunday night, the surface low lingered over southwest Minnesota, before it finally began to fill. This kept a prolonged period of gusty north winds and steady snow over eastern North Dakota and the northwest quarter of Minnesota. From 5 to 17 inches of snow fell across the area, with the highest totals generally over the central Red River Valley into portions of southeast North Dakota. Winds along and west of the Red River Valley also gusted from 40 to 50 mph, causing blizzard conditions from Sunday morning through Monday morning. Interstate 29 was closed in eastern North Dakota and Interstate 94 was closed from Fargo to Bismarck.

A stretch of cold weather resulted in a freeze up ice jam on Willow Creek in the MatSu Borough.

Flood in MATANUSKA VALLEY, ALASKA
From 21-DEC-19 00:00:00 to 31-DEC-19 00:00:00 (AKST-9)
Location: WASILLA
Flood cause: Ice Jam
Property damage: 200.00K
Crop damage: 0.00K
Reported by: Emergency Manager

Late on December 21, an ice jam on Willow Creek near the Deneki Bridge (61.77N, -149.956W) caused water to back up and flow through numerous residences.  Deneki Road and access to the Deneki Bridge was closed for multiple weeks between December 21 and January 8, 2020.  At least thirteen households evacuated on December 21-22 due to flooding or anticipation of road closures.  Six homes were damaged by flood water; there was a report of knee-deep water in one home, as well as deep flowing water around the house, ���It formed a river in my yard��� .  Numerous, (>10), cars were flooded and frozen in place.  Also some cars had to be abandoned after owners tried to drive across the flood waters and became stuck.
Examining the hydrographs, the most likely cause of the ice jam flooding was an ice dam which collapsed in the canyon, causing a mini breakup which was constricted and stopped at the Deneki Bridge.
The MatSu Borough worked with private contractors to divert the water and allow access to the Deneki Bridge and the subdivision of homes and farms to which it provides the single point of access.  Using heavy equipment, they mechanically removed the ice jam, which allowed the water flow to return to the channel, preventing it from flowing through the neighborhoods overland.
As the strong storm which impacted the area and disrupted travel over the previous two days moved into Arizona during the morning of December 27, high pressure moved into the area and brought drier weather, clearing skies and decreased winds. This resulted in a strip of dense fog forming along the middle of the San Joaquin Valley which reduced visibility to below a quarter mile at some locations during the morning of December 27 disrupting some holiday season travel plans. The fog lifted into a low cloud deck by late morning which dissipated by early afternoon.

A 29-year-old backcountry skier died after she was caught up in an avalanche near Cameron Pass.  The woman was with another skier on south Diamond Peak when the avalanche was triggered.  The skier triggered the avalanche approximately midway through her descent near the center of a steep wind-loaded gully. The avalanche started on a northeast-facing slope at around 11,200 feet. It broke above the skier and although she managed to stay on her skis, she was swept down the gully and buried on a flat bench in the runout zone.  The victim was not breathing after the avalanche.  She was declared deceased at the scene, and her body was recovered from the mountain-side.  The avalanche was described as 2 to 3 feet deep, very wide, and running close to 500 feet vertically, according to the Colorado Avalanche Information Center.  The south Diamond Peak incident marked the first avalanche death of the season in Colorado.

An initial shortwave ahead of a trough over the central CONUS crossed the region on December 16th. Snow fell initially, with accumulations of 1 to 3 inches reported by the morning hours. However, a mix with freezing rain occurred as a warm layer developed aloft. Any icing in most cases was limited to a light glaze during the night of the 16th.
Locally heavy rainfall occurred through the night of the 16th into the morning of the 17th, thanks to the passage of a surface low and enhanced lift provided by an upper jet.  Rainfall totals of between 1 and 2 inches over a 24 hour period were common across northern West Virginia.  With the ground already saturated from previous precipitation, several flooding problems were able to develop.
