The upcoming wet pattern is coming into better focus in the latest model forecasts, and indeed it looks very wet from southwestern Alaska across the western interior to the central Brooks Range. Both the traditional and AI-based ECMWF models are showing widespread amounts above 3-4 inches in the next 10-15 days, with higher amounts locally.
The strong west-east gradient across the interior reflects the fact that the flow will turn more southerly by the middle of next week, shutting off big rain potential for locations downwind of the Alaska Range; but lots of moisture will continue to flow northward across western Alaska. Here's a sequence of 500mb maps at 48-hour intervals beginning Saturday afternoon.
I picked out Kobuk as a location to illustrate the potential for very persistent rain that may eventually cause flooding issues - see below (note especially the two ECMWF models in the top panels). However, the NWS notes that most rivers in the Koyukuk and Kobuk basins currently have low flow, so it won't be a problem immediately.
