897 FXAK69 PAFG 312037 AFDAFG Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 1237 PM AKDT Thu Jul 31 2025 .SYNOPSIS... Warmer and drier weather is inbound as a high develops over Northern Alaska. Summer-like temperatures will be around through the weekend with chances for showers and storms, mostly in the SE Interior and Alaska Range, though a sporadic shower is possible in the White Mountains and higher terrain of the Interior. North Slope will be warming up and gradually losing the fog/stratus as offshore flow dominates. && .KEY WEATHER MESSAGES... Central and Eastern Interior... - Dry and warm weather with plenty of sunshine through this weekend. - A few showers remain in the Eastern Interior today with some embedded thunderstorms likely, especially in the SE Interior. - Similar story tomorrow, but storm chance extends to AK Range. - Scattered to numerous showers on Saturday in the Eastern Interior and Eastern AK Range. 0.25 - 0.50" of rain possible (Fairbanks stays mostly dry). West Coast and Western Interior... - Dense morning coastal and valley fog to 1/4 mile at times Friday morning. - Dry and warmer weather through the weekend with highs 5 to 10 degrees above normal. - Isolated thunderstorm chances in the Western AK Range and near McGrath tomorrow afternoon, Lower Yukon/Kusko Valley on Saturday, Middle Yukon Valley on Sunday. - Increasing southeast winds with peak gusts to 35 mph and isolated showers in the YK Delta Friday into Saturday North Slope and Brooks Range.. - Clearing skies along the coast as offshore flow dominates. There may be some stratus or fog returning each night, but the afternoons should be nicer and warmer overall. - Isolated showers in the Brooks Range, but overall it will be a warmer and drier weekend. && .FORECAST ANALYSIS AND DISCUSSION... High pressure moving in. There will be continued chances for rain, especially in the SE Interior and Alaska Range each day. Though the most widespread rain looks to be on Saturday as a front from the low in the Gulf moves north. This front likely stalls in over the Fortymile and Eastern AK Range on Saturday, so rain is not expected in Fairbanks. Otherwise, typical summertime showers are expected over the higher terrain of the Interior through this weekend so while it won`t be completely dry, it`ll be drier than it has been. A low in the Bering will bring gusty southeast winds and showers to the YK Delta tomorrow through Saturday, but that`s as impactful as it gets for that area. The North Slope will be warmer and drier as well, getting away from the stratus and fog for a little bit. && .FIRE WEATHER... Warmer and drier weather with much of Northern Alaska reaching the 70s by Saturday. Min RHs will get as low as 30 to 35% in Interior valleys this weekend. Showers and storms aren`t ruled out either. Most of the rain will be in the SE Interior and Alaska Range, especially tomorrow and Saturday. A front on Saturday will stall over the Fortymile and Eastern Alaska range with the potential for upwards of 0.50" in the terrain, and 0.10 to 0.25" in the upper Tanana Valley. Expect typical summertime showers for the rest of the terrain of Interior Alaska, but thunderstorm activity will be limited to the SE Interior and Alaska Range today and tomorrow. Then in the Middle/Lower Yukon Valley this weekend. Winds will be largely light, but from the Northeast through Saturday as well. && .HYDROLOGY... No concerns as rivers are cresting today then gradually falling through the weekend. && .EXTENDED FORECAST DAYS 4-7... Looking towards next week the models are in agreement with the main features that will move through the area. However, the biggest uncertainty will be what the arctic trough does as it moves across the North Slope Monday through Thursday. We could potentially see multiple fronts associated with this trough as it moves across the North Slope bringing temperatures below normal as well as chances for showers. In the Interior a shortwave feature over Southcentral Alaska will create a triple point low with the main low pressure in the Bering Sea. This will keep advecting moisture into the Interior, allowing for a continued showery pattern into the middle of next week. This would also cool the Interior down to near normal temperatures by Tuesday. Coastal Hazard Potential Days 3 and 4...None && .AFG WATCHES/WARNINGS/ADVISORIES... AK...None.
