Area forecast discussion, Apr 26, 5:00 AM AKDT, 10 hours 33 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 500 AM AKDT Mon Apr 26 2021 .ANALYSIS AND UPPER LEVELS... Upper level ridging holds strong over the eastern portions of the State, which is also reflected at the surface levels. Meanwhile, a longwave trough has finally broken through, pushing onto and across the Southwest mainland. This North Pacific low begins moving southeast briefly before becoming almost stationary just south of the Gulf. Its front and a series of waves move across the Gulf through mid-week, applying pressure on the upper level ridge, weakening it and forcing it out. This will allow more active weather to begin makings its way back into Mainland Southcentral. High pressure exists across the central Bering through mid-week as well, and is sandwiched between two low pressure systems. One of which is a polar low, whose trough extends down across Southwest Alaska, while the other is the remnants of Typhoon Surigae. The polar low in conjunction with the high pressure ridge will eventually allow colder northerly upper-level flow to move across the Bering. && .MODEL DISCUSSION... Models remain in good overall synoptic agreement through the forecast period. Discrepancies across models for a digging trough are low and will be non-impactful. && .AVIATION... PANC...VFR conditions and light winds will persist. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2...Mon and Tue)... Our blocking ridge of high pressure will hang on for a few more days before slowly yielding to clouds and even chances for precipitation across the southern mainland on Wed. First, satellite clearly shows little change to the synoptic pattern from the weekend. High pressure remains parked over the Copper River Basin while areas of low pressure continue to pass through the Sand Point area. Caught in between these systems is Kodiak Island where frontal system after frontal system continue to make for cloudy, breezy, and wet weather. The next front in the series has slowed down some this morning, so we have trended slower with PoPs over the island. However, we do expect rain to start there once again by late this morning/early this afternoon. Once it returns, expect light rain to be persistent all the way through Tue with broad onshore flow associated with a decaying stationary front. Over the mainland, abundant sunshine and warm temperatures are once again in store for today. However, the area of high pressure will be under siege from just about all directions as we head toward the middle of the week. One of the first features to move in will be a cold upper level wave from Canada. This shortwave will slide north to south along the AlCan Border late Monday leading to a slight cool down Tuesday over the Copper River Basin. Another piece of energy will drift south from the Interior on Tue allowing for continued deterioration of the high pressure. As it wanes, it will open the door for some cloud cover to filter back in late Tue. It will also create the possibility of some southeasterly gap winds through places like the Turnagain and Knik Arms by late Tue. Overall, the next few days will continue to feature dry conditions with slightly more "normal" April weather returning as we head through the week. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2: Monday and Tuesday)... An upper level trough over Southwest Alaska remains sandwiched between ridging over the eastern Interior and western Bering. Embedded within the trough are two shortwaves, one over the AKPen and the other over the North Pacific. The shortwave over the AKPen will push weak pulses of energy onto the Mainland this morning, continuing the overcast and showery pattern through midday. By this afternoon, the shortwave over the North Pacific will push to the south as the upper level trough amplifies. This will pull the low over the AKPen southward as well, bringing in much drier air from the Interior. Clearing skies overnight Monday into Tuesday morning will drop the lows a few degrees from those observed Monday morning. The weather on Tuesday should be mostly clear with temperatures remaining above average. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2: Monday and Tuesday)... Mostly calm conditions are expected throughout the region as high pressure builds in from the west. A compact low over the AKPen will bring rain and overcast skies to the Central and Eastern Aleutians today. These should begin to taper off Tuesday morning as the low gets pulled south underneath a rapidly amplifying trough. Meanwhile, a ridge is expected to build in from the western Bering to the north of the remnants of Typhoon Surigae. Due to the ridge, the now extra-tropical cyclone will remain south of the forecast area, but its front will bring gale force winds and rain to the Western Aleutians Tuesday. && .MARINE (Days 3 through 5: Wednesday through Friday)... The forecast period overall looks quiet with winds generally below 35 kts and less than 20 ft seas for much of the Bering and western Gulf. The only exception is the marine waters around the southwestern Bering and the Western Aleutian Islands which are expected to experience gale force winds Wednesday as a result of a low pressure system to the south (former Typhoon Surigae). Winds will gradually continue to weaken over this area Wednesday evening and night as the low exits across the North Pacific. Lastly, a low over the northeast Pacific will lift northward toward the eastern Gulf Thursday through Friday. There is a high level of uncertainty in the track and strength of this low, so stay tuned. && .Long Term Forecast (Days 4 through 7: Thursday through Sunday)... Beginning Thursday, the stretch of nice, sunny, and dry weather over Southcentral Alaska comes to an end to an extent. A broad upper trough is expected to set up over the Alaska Mainland during this time period. This means cooler temperatures, but likely near normal for this time of year. There will also be an increase in the potential for precipitation, though the details of individual features is highly uncertain. Overall, expect an increase in the amount of clouds throughout the region, with some sun still possible - just not like it has been of late. Meanwhile, weather across the Bering Sea and Aleutians looks quiet as an upper ridge holds Pacific storms off to the south. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...NONE.
