A strengthening low moving north into the eastern Gulf has brought heavy rain and warm temperatures to Southeast. Up to 2 inches of rain through tonight is possible leading to localized flooding concerns. This low is headed due north toward the northern Panhandle, then will turn northeastward and exit into Canada tomorrow. However, a separate low in the southern Bering will quickly replace it.
The Bering low is weakening as it moves into the AK Peninsula later today. Snow showers are likely over the Aleutians and AK Peninsula, but less likely over the rest of Southwest. It will cross into the Gulf as a very wounded pressure system but then regenerate behind the departing low heading into the weekend. That means rain, and lots of it, continuing in Southeast through the weekend.
Southcentral is sandwiched between both disturbances. Clouds will increase in PWS today with snow possible in the afternoon or evening hours. Snow will then intensify overnight. 3 to 6 inches are possible in Cordova and Valdez. Elsewhere, in Anchorage and the Valley, sunshine will return as AM low clouds and fog burn off. Mostly to partly sunny skies are expected in the Kenai Peninsula.
Clouds will increase a bit in Anchorage tomorrow evening but no measureable snow is anticipated.
It will be unseasonably chilly through the weekend. Highs 20s Southcentral, teens to single digits Interior, and subzero to single digits Slope and West.
