ANCHORAGE, Alaska — Get used to hearing a lot about an upper level trough. In the big picture, it is our primary weather feature all the way into next week.
What does an amplified upper trough mean for us? It means unsettled, chilly, and wet weather for many parts of the state.
If you look outside this morning in Anchorage or anywhere in the Cook Inlet region, you're thinking, "What's the big deal? It looks gorgeous." In fact, most of Southcentral is shaping up to be partly to mostly sunny today. But it will also be cool. Highs will to out in the 40s, a good 5 to 10 degrees below average for the beginning of May.
Anchorage and the Valley are seeing very low dewpoints, thanks to cold dry air advecting into the region since yesterday evening. That is why it is clear and also why it is cold---lows hit the teens over east Anchorage and parts of the Mat Su.
