Discussion:

The overall weather pattern remains mostly unchanged this morning as an arctic airmass remains entrenched over most of Alaska.
Temperatures have fallen into the negatives across much of inland Southcentral where calm winds and clear skies have allowed for efficient radiational cooling. Many of the areas experiencing strong winds have seen temperatures remaining above zero but with below zero wind chills. The dense arctic airmass has continued to produce strong gap flow winds through north/south oriented gaps and passes, as has been the case the past 24-36 hrs. The strongest of these winds have been through the Matanuska Valley where wind gusts of up to 90 mph were reported. Strong winds were also felt along the Knik Arm to north and west Anchorage and along the coast of the northern Cook Inlet, including Kenai and Nikiski. These winds have subsided somewhat this morning but are expected to pick back up later this morning, and continuing through tonight before gradually decreasing through Monday.

Strong winds have also created ground blizzard concerns through many of the passes, including Broad Pass, Isabel Pass, and Thompson Pass.
Webcams indicated winds gusting to 50 mph through Thompson Pass are still created significant blowing and drifting of snow this morning so have extended the Blizzard Warning through noon today. These conditions through the passes should improve later today as snow in these areas becomes more compacted and harder to loft, and winds gradually subside. However, gusty winds will continue to produce dangerous wind chills heading into the workweek.

Accumulating snowfall is still ongoing over northern Kodiak Island this morning. Moderate to heavy snowfall fell most of the night with strong winds reducing visibilities down to under a mile. Conditions have improved, but another shortwave trough rotating around the parent low will bring another round of moderate snow by late morning to early afternoon with up to several more inches of accumulating snowfall. By Monday morning the Gulf low will start to shear apart and move eastwards. Looking at the upcoming workweek, the weather looks to remain cold and mostly dry, with gap winds continuing for favorable locations.
