Last night (11/5) the Turnagain Arm area saw around 2 inches of light snow and skies will be clearing through today. Temperatures have been in the teens to low 20’s F. Winds have been light in the 5-10mph range from the north east.
Calm and mostly clear conditions should prevail into Friday. A low pressure system is headed our way for the weekend with snow in the forecast. How much this storm will impact the Turnagain Arm region is uncertain at this point.
