Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 141 AM AKDT Thu Apr 22 2021

SYNOPSIS . Another pleasant spring day across the forecast area with generally partly cloudy skies. Some patchy low clouds in the Arctic will be moving through with a period of cloudy conditions and some patchy fog east of Utqiagvik. A decaying front moving into the Lower Yukon Delta will bring some isolated showers and clouds south of Mountain Village. Winds generally less that 15 mph with the strongest winds in the Lower Yukon Delta and the Western Alaska Range. Temperatures will generally be above climatological normals over most of the forecast area into the weekend.

DISCUSSION.

Models . 22/00Z solutions continue to handle the big ridge well with good run to run continuity. No significant difference in the solutions through the midrange, with some differences in how they handle the breaking down of the ridge beyond 102 hours. With the relatively quiet pattern a general blend of the solutions will be utilized for most elements. The exception will be temperatures, will maintain continuity with only some minor tweaks to accommodatesome minor adjustments. Temperatures will continue to be warmer than climatological normals across most of the forecast area into the weekend.

Aloft . At 500 hpa . Troughing well east of the state as the 570 dam high that was over the Bering Strait yesterday has moved over Kotzebue at 567 dam. Ridging associated with the high extends northwest over the Western Arctic, southwest over St Lawrence Island and the Central Bering Sea, and southeast over Prince William Sound and the Eastern Gulf of Alaska. The lows south of the Eastern Aleutians have merged with a 527 dam low 100 nm south of Unalaska. Ridging will slowly rotate, and by Friday morning the high will be over Huslia at 563 dam with ridging extending north over 150W, southeast over Cordova and the Eastern Gulf of Alaska, and west over the Bering Strait, Gulf of Anadyr, and the Kamchatka Peninsula. The low south of Unalaska will move southeast to 400 nm south of Kodiak Island, while a 537 dam low will develop over Cold Bay. Saturday morning the 562 dam high over the state will be cutoff as the low south of Kodiak Island moves southeast. The High will be quasi stationary over Ambler with ridging extending northeast over the Beaufort Sea, south over the Gulf of Alaska and southwest over the Pacific, and northwest over Wrangel Island. The low that developed over Cold Bay will move over the Central Bering Sea at 531 dam, while a 515 dam low will be high in the Arctic At 850 hpa. -10C isotherm is northeast of the state. The 0C isotherm lies from Yakutat to Utqiagvik with the dome of warm air, around +6C, centered over the Chukchi Sea. No significant change is expected through Friday evening, then the dome of warmer air, around +6C, shifts over the Central Brooks Range.

Surface . A 1034 mb high is over the Central Brooks Range this morning with high pressure extending east to a 1033 mb high near Ft McPherson NWT, southeast to a 1032 mb high near the Yukon/NWT Border, and a 1028 mb high in the Copper River Basin, and north across the Eastern Arctic. A 992 mb low is 100 nm south of Unalaska with a decaying front pushing north to the Lower Yukon Delta today. The weak front that moved northeast out of the Chukchi Sea yesterday continues to move northeast across the Arctic as it weakens. By Friday morning high pressure will extend west across the state from a 1031 mb high near Ft McPherson NWT to a 1028 mb high near Ambler, then west to the Chukotsk Peninsula. A 1028 mb high will develop in the Upper Yukon Valley in the Yukon Territory, and a 1023 mb high will develop in the Copper River Basin. Weak leeside troughing will develop north of the Alaska Range with a 1018 mb low near Lake Minchumina. Saturday morning a benign pattern will develop over the state dominated by high pressure.

Arctic Coast and Brooks Range . Some patchy clouds and patchy fog moving through the area, but generally partly cloudy. Temperatures above climatological normals through the weekend with highs in the 20s to 30s, and lows in the single digits and teens. Winds southwest to south at 5 to 15 mph becoming south to east by late this evening.

West Coast and Western Interior . Partly cloudy with the exception of the Lower Yukon Delta where a decaying front will bring some isolated showers to the area today along with cloudy skies. Temperatures will continue above climatological normals through the weekend with highs in the 30s to 40s along the coast, and 40s to 50s inland. Lows will be in the teens and 20s. Winds north to east at 5 to 15 mph.

Central and Eastern Interior . Partly cloudy. Temperatures will continue above climatological normals through the weekend with highs in the 50s to around 60, and lows in the upper 20s to around 30. Winds variable to 10 mph.

Coastal Hazard Potential Days 3 and 4 . None.

Extended forecast for days 4 to 7 . Generally clear and warm across the area into next week. A weather front may bring some clouds to the West Coast Tuesday, then a front in the Arctic will bring some clouds to the Chukchi Sea Coast Wednesday. Some cooler dry air will move into the area from the northeast midweek.

Fire Weather. Temperatures will be warming into the 50s to around 60 in the Interior with Relative Humidity values falling into the 20 to 35 percent range. Winds in the Interior picking up to east and southeast to 10 mph during the afternoon, otherwise light and variable. No precipitation expected through the weekend.

Hydrology. Breakup will accelerate some as the temperatures in the Central and Eastern Interior will generally be above climatological normals during the day, and near or above normal climatological temperatures overnight allowing the melting process to be almost continuous. Smaller streams, creeks, and sloughs continue to open up as melt runoff is making it into them, and water is running on top of ice in some of them, so caution should be used if you are near them. River Ice will break down much faster that lake ice as upwelling can erode the ice rapidly without being visible, so use extreme caution.

AFG WATCHES/WARNINGS/ADVISORIES.

None.
