Wider weather episode

A strong surface low associated with an upper level trough in the Gulf of Alaska increased snowfall over Southcentral Alaska on January 5th as flow shifted southwesterly. The trough was negatively tilted, which further aided in providing lift for additional snowfall. In addition, the low created a very tight pressure gradient over Kachemak Bay and the southern Kenai Peninsula January 6, 2026. In addition to the pressure gradient, heavy snow developed over Kachemak Bay producing heavy snow and blowing snow over the region. Strong Westerly winds also produced high surf along the Homer Spit.
