Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 208 AM AKDT Wed Apr 24 2024

SYNOPSIS
Most of Northern Alaska remains quiet as a big bubble of high pressure sits overhead. A front stretching from St. Lawrence Island to the YK Delta will continue to bring some light rain and breezy conditions. This front gradually pushes inland this morning with mainly light rain from the Seward Peninsula southeast. Along the North Slope, is mostly quiet today, but a high in the Arctic will strengthen bringing strong easterly wind and blowing snow as we head into Thursday.

DISCUSSION
Upper Level Analysis...
At 500 mb, a 498 decameter low over the Central Bering Sea will remain nearly stationary as an associated front moves into Western Alaska this morning. A 543 decameter high over the Interior will be strengthening and center itself over the Central Interior this afternoon. A weakening 537 decameter low over Juneau has a front extended into the southern Yukon and far southeastern Interior which has provided some isolated rain showers. Otherwise, the high over the Interior will remain dominant through the weekend, then try to break down heading into next week.

Surface Analysis...
A weakening 973 mb low over the Central Bering Sea is extending a front which will be moving into the West Coast this morning bringing areas of rain and breezy conditions. Otherwise, a high remains dominant over the rest of the state keeping the weather mostly quiet today. A thermal trough has been developing in the Interior which has sparked a few isolated rain showers over the terrain and that will be the case once again today.

West Coast and Western Interior...
A front is currently bringing light rain from St. Lawrence Island to the YK Delta. This gradually moves into the Seward Peninsula around 7 to 10 AM this morning with areas of light rain as well.
It will be breezy with winds around 20 to 25 mph, gusting to 30 mph. Periods of light rain and rain showers look to continue from Diomede to Anvik as the front remains nearly stationary through Thursday, then conditions to improve and the rain showers will be less numerous by Friday. Temperatures will be mild, but near to slightly above average for this time of the year with highs in the mid 30s to near 40 along the coast. In the Western Interior northeast of Anvik, high temperatures will be in the upper 40s and low 50s as most of the area remains dry.

Central and Eastern Interior...
Outside of a few higher terrain rain showers, our weather will remain mostly quiet as a banana high stretching from the Yukon through the Interior and around to Wrangell Island keeps us dry.
Winds will be increasing a bit today with the strongest being around Delta Junction as a Tanana Valley Jet strengthens. Expect gusts as high as 30 mph this evening around Delta Junction and gusts 15 to 20 mph for the remainder of the Interior. There will also be weak gap flow with gusts to 35 mph through the AK Range passes tonight through Friday night. Otherwise, our warm and mostly dry weather will persist through the end of the week and into this weekend.

North Slope and Brooks Range...
Quiet weather today will come to an end along the coast as easterly winds increase on Thursday. There will likely be some blowing snow and lowered visibility, especially southeast of Utqiagvik towards Deadhorse and Demarcation Point. At this time, a Winter Storm Watch is issued for the Central and Eastern Beaufort Sea Coast for blowing snow and potentially blizzard conditions beginning on Thursday. Temperatures will be around average to slightly above with highs in the teens to around 20 today, but they will be dropping into the teens and single digits through Friday. South from the coast, winds won't be as strong and high temperatures will be in the teens and 20s with lows in the single digits and low teens. In the Brooks Range, expect highs in the 30s with lows in the teens and 20s.

Extended Forecast For Days 4-7...
Ridging looks to remain dominant through this weekend but it will be weakening, especially on Sunday. As this ridge breaks down, there is some model disagreement on what exactly happens, but there is some consensus on troughing entering the North Slope and eventually the Interior and West Coast towards the beginning of next week. Exact details will continue to be evaluated, but some more active and slightly cooler weather may be headed our way as we move into next week.

Coastal Hazard Potential Days 3 and 4...None.
