Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 502 PM AKST Sat Jan 9 2021 .ANALYSIS AND UPPER LEVELS... Two lows, one over the southern Gulf approaching Kodiak Island, and a second located west of Dutch Harbor, are the two primary features driving the weather across southern Alaska this afternoon. Both are large features, moving towards each other and will eventually merge together late tonight. In the meantime, occasional blizzard conditions have been reported in Dutch Harbor with peak wind gusts near 70 mph with heavy snow this morning. This low has a steady supply of polar air feeding into it from the north and northeast, with temperatures around 30 in the Pribilofs, and within a few degrees of zero across the Kuskokwim Delta. The Gulf low has warmer air with it and much less cold air to draw from. Nevertheless, the return flow west of the center has lowered visibilities in Kodiak due to snow, though temperatures have now warmed several degrees above freezing. Precipitation is becoming steadier and heavier across the Kenai Mountains, with a swath of stratiform precipitation evident on Middleton Island radar imagery. Elsewhere, little in the way of precipitation is making it inland, but the associated cloud cover sure is, which is keeping Southcentral relatively mild in the teens and 20s as compared with points further west across Southwest Alaska. The 12Z Anchorage sounding has a similar atmospheric profile as 24 hours ago, but is significantly drier, especially in the mid-levels. In the upper levels, a large longwave trough is in pace across the Bering, with a piece of the North American ridge extending into the Copper Basin. An embedded upper level low is associated with the Aleutians surface low west of Adak, with a strong negatively- tilted shortwave trough associated with the Gulf low across the southern Gulf. && .MODEL DISCUSSION... Model agreement remains good on the synoptic scale this afternoon regarding the two lows merging into one, then remaining stationary between the Shumagins and Kodiak Island through at least Monday afternoon. Discrepancies and uncertainty pertain to any lows and disturbances wrapping around the main low, where timing and intensity differences are large. Since these features have a large impact on the weather locally, confidence with those is lower. Nonetheless a continued cloudy, warmer than normal weather pattern with frequent precipitation along the coast, cold conditions across interior Southwest Alaska, and frequent snow shower activity across the Bering and Aleutians is very likely, with confidence in that overall weather pattern high. && .AVIATION... PANC...VFR conditions and northerly winds will persist. The winds could become gusty at times, especially tonight. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Today through Tuesday)... An upper-level wave and associated surface low continues to track northwest from the central Gulf toward the Barren Islands. As it does, a front will move toward the Southcentral coast with easterly winds and precipitation both on the increase. The precipitation that began as snow for Kodiak City this morning is transitioning to a rain/snow mix as warmer air tries to work in from the Gulf and is expected to become all rain by later this evening. The precipitation across the Southcentral coast will also start this evening as all snow, but should mix with rain along the immediate coast (Seward, Whittier, Cordova) as a southerly flow ushers in warmer air. By Sunday morning, any mixed precipitation should become all rain as temperatures climbs into the mid to upper 30s. Gap winds will also be on the increase this evening, especially along Turnagain Arm. Colder air bottled up over the Copper River Basin will help increase northeasterly drainage flow winds along the Matanuska Valley and through Thompson Pass, where blowing snow is possible overnight into early Sunday. With the track of the low moving toward the Barren Island, winds aloft ahead of and along the front will be easterly. The easterly winds will help being plenty of moisture in the form of snow to the Kenai and Chugach mountains, but will limit precipitation for places farther inland across the Kenai Peninsula. These features will then phase with a larger trough moving west across the Aleutians. The re-established trough over the AKPEN will allow multiple weaker waves to lift north over the Gulf. Additional rounds of coastal mixed rain/snow and mountain snow are expected late Sunday into Monday and again late Monday into Tuesday. Interior locations will see limited precipitation due to a southeasterly downslope flow. Gap winds will also persist as each wave moves along the coast. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)... Quiet weather will continue for Southwest through this evening with a mostly clear to partly cloudy sky. Low pressure off to the south along the Alaska Peninsula and the eastern Aleutian Chain will combine with higher pressure off to the northwest. This will create a tightening pressure gradient across Southwest heading through the remainder of the day and into the evening hours leading to developing breezy conditions. Along with the breezy conditions, some upper level shortwaves associated with a surface low pressure southeast of the AKPEN will send some moisture into Bristol Bay starting tonight. Due to the deep southeasterly flow, the typical areas that downslope will see minimal if any precipitation. Areas such as Dillingham, New Stuyahok, and Koliganek west to the east facing side of the Kuskokwim Mountains (due to upslope) will have the best chance of seeing some snow. Most areas are expected to see upwards of an inch with higher amounts in the mountains. With the increasing winds, blowing snow is a concern in Dillingham as the snow is expected to be light and fluffy with any snow that falls tonight into Sunday. As a result, visibility may becomes as low as 1-2 miles at times. Some moisture may make it over the mountains to bring a slight chance of snow to the southern areas of the Kuskokwim Coast late Sunday into early Monday. The best chance time for Bethel to see any light snow comes Monday morning into Monday afternoon. Winds will begin to gradually ease some on Monday as the pressure gradient weakens over the area. Another piece of energy may bring some more light snow to Southwest on Tuesday. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)... A storm force low currently to the south of Nikolski will continue to slowly move off to the south towards the North Pacific. Its front which has been plastering Dutch Harbor all day with strong gusty winds upwards of 55-65 mph with reductions in visibility to 1/4 mile (blizzard conditions) at times will continue to slowly pivot over the region through this evening. Due to this, a Special Weather Statement has been issued for Dutch Harbor through 9 PM this evening. Strong gusty winds and blizzard conditions will slowly abate around or just after 9 PM, though gusty winds upwards of 30-40 mph can still be expected through the overnight. The main story behind this storm system will be the broad and cold northerly flow across much of the Bering Sea for the next 3 days. Cold air flowing over a relatively warm body of water will create for an unstable atmosphere which will cause snow showers/squalls for the next 3 days. Basically, many areas along the Aleutian Chain and the Pribilofs can expect brief reductions in visibility at times as any one snow shower moves through before going back up to unrestricted visibility. Along with the cold air and the snow showers will be small crafts across a good chunk of the Bering with gale force winds north and east of the Pribilofs and to the south. West of the Pribilofs, mainly small crafts are expected. The typical bays and passes are expected to blow stronger (maybe high end gales for gusts) than out over the open water where the air is channeled through gaps especially Sunday through Tuesday morning. && .MARINE (Days 3 through 5...Tue through Thu)... Gulf of Alaska: A Southwest Gulf low curves over Kodiak Island and continues into the Alaska Peninsula for Wed. Model track and development are inconsistent making forecast confidence low. Easterly small craft winds and waves spread across the Gulf with gale force gusts through Cook Inlet and Shelikof Strait through Wed, becoming southwesterly small craft winds Thu. Gulf wave heights start at 6-10 feet Tue, building to 14-20 feet Wed before diminishing to 6-8 feet Thu. Bering Sea: High pressure over the Western Aleutians and Bering couple with a low in Southwest Alaska through Thu. Model track and development vary, making forecast confidence fair through Thu. Widespread northerly small craft winds and waves with local gale force gusts push through the central and eastern Bering Tue, diminishing Wed. Wave heights 7-10 feet except locally to 14 feet in the Western and Eastern Aleutians Tue, diminishing Wed. && .LONG TERM FORECAST (Days 3 through 7)... The latest model guidance shows broad troughing over Southern Alaska, extending across the Bering early next week with a deep low positioned over the Gulf. Multiple embedded upper-level waves will move across Southcentral and Southwest Alaska while the system remains relatively stationary over the southern AKPEN. Large scale cyclonic flow will keep cold, northerly flow across the Bering through mid-week. This will aid in the development of smaller polar lows moving southward across the Bering. Most of the moisture impacts will be present across the Gulf and along the North Gulf Coast, moving to the southeast by mid-week as the system occludes and begins weakening. Model spread is still relatively large. Thus, uncertainty is high for a second strong low looking to approach the southern Gulf that could bring another round of heavy precipitation to areas along the north Gulf Coast, as well as high winds and seas across the Gulf. Impacts will be very track dependent, including precipitation type for both Southcentral and Southwest. This includes winds across the mainland, which can induce warming, especially if southeast flow across the mountains is able to mix with flow at the surface. && .AFC WATCHES/WARNINGS/ADVISORIES...
