Forecast Synopsis SIWO

Forecast Synopsis for 4/22: 

A series of lows will be moving north across the Bering, bringing periods of gusty winds and a gradual warming trend through the weekend. The first low is already producing areas of gusty winds between 35 and 45 kts, as well as some moderate precipitation. This is resulting in occasional blizzard conditions. These are expected to last through tonight. Temperatures will warm up behind a front that moves over St. Lawrence Island and the Seward Peninsula, resulting in a warming trend over the next couple of days. As the low continues to shift NW, another round of gusty easterly winds are likely on Thursday with speeds up to 40kts over St Lawrence Island and 25kts over the NW Seward Peninsula. Winds will become more static by the weekend as the low quickly fills in. Another low will be moving across the Aleutians and set up in the Southern Bering, getting blocked by an area of high pressure building over the Arctic. This will result in another round of gusty, NE winds by Sunday afternoon with gusts up to 35kts over St. Lawrence Island and up to 20kts over the NW Seward Peninsula. Winds will gradually weaken through the start of the next week as this second low weakens.
