Strong storm to bring wet and windy conditions to Southcentral
Uneventful is the perfect way to describe the end of the workweek, as afternoon sunshine and highs in the 40s gripped Southcentral. Hopefully you enjoyed the sunshine, as clouds will steadily increase through the night ahead of our next storm system. Due to increasing clouds through the night, the Aurora Borealis may be hard to see for many. If you're looking to catch a glimpse of it, your best bet is to head north into the valley or out near Glennallen.
Saturday morning will start out like many the past week, with cloudy skies and slightly breezy conditions. This all comes ahead of a strong storm that has been taking shape over the Aleutians. Plenty of wind energy is associated with this storm, as winds have already gusted near 70 mph across the island chain. As the storm gradually shifts to the northeast over the coming hours, not only will the winds affect a large portion of the state but rain and snow can be expected for many.
In advance of the incoming storm a large portion of the state is under a variety of warnings. From winter storm warnings and winter weather advisories in the interior and western portions of the state. To high wind watches, flood watches, and winter weather advisories to Southcentral, the reach of this storm system will be felt across thousands of miles.
The first half of Saturday will continue the trend of relatively uneventful weather for Southcentral, with winds slowly picking up through the day. If you have any plans to take part in Trick or Treating in Downtown Anchorage, while no rain is expected it will be breezy at times. The extent of the winds for Anchorage won't arrive until late Saturday night when a high wind watch goes into effect. By the afternoon hours, snow will begin spreading into the northern Susitna Valley, with areas along and north of Talkeetna likely seeing upwards of 4-10 inches of snow from Saturday into early Monday morning. Elsewhere, expect winds to remain quite breezy with gusts anywhere form 30-50 mph across Southcentral. Higher wind speeds can be expected on the Anchorage Hillside and Turnagain Arm, where winds could gust up to 75 mph. While most of Anchorage will be on the downsloping side of the storm, rain would typically be hard to come by, however due to the amount of moisture associated with this storm system rain showers will be off and on through the weekend. The heaviest rain will be situated on the eastern side of the Kenai and Western Prince William Sound, it's here where not only will the winds be breezy, but 4-6 inches of rain can be expected from Saturday through Monday. A flood watch has been issued in advance of this storm system due to the possibility of rapid water level rises.
The rain and wind will linger into Sunday and the first part of Monday before tapering off, with slightly cooler air filtering in on the backside of it. Temperatures for now look to slowly drop near 40 degrees by Halloween with overnight lows near freezing, which is still unseasonably warm for this time of the year.
Stay cautious this weekend!
