A relatively dry northerly flow will continue this morning over western Alaska. Moisture flowing out of Canada will push westward through the Fairbanks area, bringing a chance of showers to the western Interior. Rain and isolated thunderstorms will redevelop in Fairbanks this evening as clearing this morning. Highs will reach the 60s in the Interior with mostly to partly cloudy skies.
Meanwhile, an occluded front draped over the Gulf of Alaska is bringing rain to the Alaska Peninsula. Dry air to the north has prevented cloud cover along the front from moving into the mainland. As this dry flow tapers off later today, clouds will be allowed to spread over southern Alaska. Where the upper flow is from the south over the eastern Gulf, clouds are increasing and pushing into the Panhandle.
As a result, look for mostly cloudy skies this afternoon over most of southern coastal Alaska with rain showers likely in the SE Panhandle, PWS, the eastern Kenai Peninsula, and Kodiak. Highs will top out in the low 50s in SE with upper 40s to upper 50s elsewhere.
The Bristol Bay and Kuskokwim regions are in for another partly cloudy day. Expect 50s to near 60 for highs.
Sufficient cold air advection will drop temps to near or just below freezing in northern Alaska tonight. As rain develops near the the thermal trough axis over the Interior later this evening, rain will change to snow over the higher elevations of the Brooks Range. Up to 5 inches is likely into tomorrow morning.
Partly to mostly cloudy skies and upper 50s are forecast for Anchorage. Temps will be a little cooler tomorrow and Thursday with a chance of showers.
