Wet to dry, wet to dry but back to dry today

By  | 

ANCHORAGE (KTUU) - While under partly sunny skies Wednesday Anchorage warms to near 62 degrees.

High pressure looks to clear clouds and dry off the western part of Southcentral for the most part west of Prince William Sound. Our next weather concern is a strong frontal system, that arrives in the western Gulf of Alaska Wednesday/today that lifts into the northern Gulf on Thursday. This system is attached to a deep Bering low that is holding tropical moisture from the remnants of Typhoon Faxai. Given the tropical moisture feed, this feature is expected to bring some of the heaviest rains and strongest winds we have seen in a couple of months. Rain will first overspread Kodiak Island late Wednesday, lifting north by Thursday morning.

Rain will also spread across the eastern Kenai Peninsula overnight tonight (Wednesday) into early Thursday. Due in part to the westward track of the compact low in Prince William Sound as it phases in with the larger frontal system. More rain then makes it into Prince William Sound by midday Thursday.

Partly sunny in Anchorage Wednesday after early morning fog as we warm up to 62 degrees while we see winds pick up to 20 mph this afternoon. Mostly cloudy tonight as we drop down to 54 degrees with winds out of the southeast at 15 mph but up to 30 mph along Turnagain Arm and in higher elevations.

Cloudy on Thursday with a high of 65 degrees and northeast winds at 15 mph but up to 35 mph along Turnagain Arm as well as in higher elevations. Thursday night while under cloudy skies we cool down to 52 degrees with winds out of the southeast at 15 mph but up to 30 mph along Turnagain Arm and in higher elevations.

Looking ahead, Anchorage will be cloudy on Friday with a high of 61 degrees.

Fire Weather: The Copper River Basin will continue to be the primary fire weather concern. Temperatures will remain in the 60's while minimum relative humidity values slowly climb higher each day into the 40-50 percent range. Gusty winds out of the southeast will develop in the river valley again Wednesday afternoon. For other locations, showers will begin to diminish overnight across the Interior while areas of rain develop across Prince William Sound for Wednesday. A strong frontal system then moves over the Southcentral mainland with rain and gusty winds out of the southeast for late Wednesday through Thursday. While rain will be likely over inland areas, amounts will generally be less than a 10th of an inch through Thursday night.
