First freeze of the season will occur for many this week
Clouds skies have gripped the region for most of Tuesday keeping temperatures on the cooler side for many. While highs are still seasonal, a series of upper level disturbances will usher in the coolest air we've seen in quite some time. Ahead of the cool down we'll see scattered showers come in two waves. Wave number one is already occurring across Southcentral and will dissipate into the evening hours. Wave number two will arrive Wednesday afternoon and bring some light rain, with snow showers in higher elevations. Once the cold air filters into the region, we'll see a noticeable difference in our mornings.
Skies clearing out Wednesday night into Thursday will allow temperatures to dip down into the mid 30s bringing frost to many areas. The biggest cool down arrives Thursday night, where many will likely see the first freeze of the season. For now the airport looks to only dip down to 33, but East Anchorage will likely see the first freeze of the season both days.
We see a brief drying period Thursday through Saturday before our next storm system takes shape. This looks to not only bring some beneficial rain to the region, but will also keep cloudier skies in the forecast. It's possible meany areas could pick up an additional inch of rain when all is said and done, as this system looks to arrive overnight Saturday and not taper off until Monday.
The fall pattern has arrived and looks to show no signs of letting up as we close out September.
Have a great hump day!
