Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 507 PM AKDT Sat Jul 11 2020

ANALYSIS AND UPPER LEVELS.

A 500 mb low east of the Yukon Delta has been producing some thunderstorms throughout the day in the Kuskokwim valley. This upper level low will move southward through the next few days and be the focus for thunderstorm activity this afternoon and evening, and again Sunday. While Southcentral Alaska remains unstable and conducive for thunderstorms today, they should be more widespread in Southwest Alaska because of this upper level low.

The Bering Sea remains under high pressure causing low stratus over the majority of it. A front along the Central Aleutians is shearing apart as it runs into the ridge.

MODEL DISCUSSION. Models are in good synoptic agreement through the early part of next week with some more noise creeping into the pattern for the second half of the week. This is most evident in the Bering Sea where the GFS has a high in the central Bering and the ECMWF and Canadian show a closed low in the southern Bering Sea. However, this will mainly impact the Aleutian chain and the practical difference may just be wind direction and whether there is predominately fog or rain.

AVIATION. PANC . Winds have turned to the southeast this evening and could be gusty at times off the Turnagain Arm. Showers will persist around the airport into tomorrow, with some isolated thunderstorms around the terminal this evening. Ceilings will drop under 5000 ft at times, but should remain above MVFR conditions.

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2: Today and Sunday) .

The upper level low continues to drop south over western Alaska, pushing ample moisture into the Southcentral region. This, coupled with the unstable airmass, will produce isolated to scattered thunderstorm activity across the Kenai Peninsula north into the Susitna Valley and western Copper River Basin this evening. The steering flow is out of the west, thus expect the storms that do form to move to the east and mainly be along the Talkeetna and Chugach Mountains. Some storms will form off the Alaska Range as well and move across the Susitna Valley. Following the convective activity tonight, west to southwest flow will usher in more stable air along with more moisture, thus increasing the chances of rain across much of south central Alaska Sunday, particularly the Susitna Valley.

A surface low will be under the low over Southwest Alaska and a surface low will form along a front south of the Alaska Peninsula tonight. This low intensifies as it moves into the western Gulf of Alaska Sunday night and Monday. In advance of this low a ridge builds in the eastern Gulf of Alaska and intensifies Monday. The interior thermal trough, while not strong, will be in place as well. The combination of the intensifying ridge and interior trough will be the driver behind the gap winds through the Chugach Mountains as well as along the Copper River the next few days.

SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3).

An active pattern is set up across Southwest Alaska today as an upper level trough digs into the region. Instability and convection accompany this feature as it moves southward through the end of the weekend. Thunderstorms have already developed over the Kuskokwim Valley and interior Bristol Bay. Widely scattered thunderstorms are expected to continue for interior locations, with areas just north of New Stuyahok looking like a hot spot for storms late this afternoon into the evening hours.

This pattern will continue into Sunday, though a bit weaker with less thunderstorm activity expected as there is slightly less instability in place. However, isolated thunderstorms remain in the forecast, once again staying farther inland away from the coasts. Quieter weather moves in to start the week on Monday with showers tapering off across the Southwest.

SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2).

With high pressure across the Bering, fog and low stratus will remain in the forecast over the next few days, with conditions improving for the daytime hours. Low pressure continues to slide eastward south of the Aleutian Chain, keeping relatively weak winds with a chance of precipitation. However, there is some model uncertainty start Sunday afternoon whether this area of low pressure will develop into a closed low south of Kodiak Island, which would bring more precipitation and stronger winds to areas south of the Alaska Peninsula.

MARINE (Days 3 through 5: Tuesday through Thursday).

High pressure lingers across the Bering with easterly winds and waves across the southern half and southerly winds and waves over the northern half through Thu. High uncertainty comes with the initial position and track of a North Pacific low, bringing problems its movement and wind directions with said low through Thu. Confidence is good for less than small craft winds and waves south of the Aleutians through Thu.

Over the Gulf, a low center will track across the Gulf, however certainty is low for frontal positions through Thu. East to southeast winds and waves are expected across the Northern Gulf with less than small craft speeds. We expect a shift to northerly winds and waves around Kodiak Island and the western Gulf by Thu.

LONG TERM FORECAST (Days 3 through 7). By Tuesday, the upper level low that is near Southwest Alaska today will have moved over Kodiak Island and be in the central Gulf of Alaska. This will start the period with high pressure over Southwest Alaska and a front along the north Gulf coast. The high pressure is not terribly strong but should spread over Southcentral Alaska for the middle of next week. Southwest Alaska will be susceptible for low stratus to advect into the region off the Bering Sea, though rainfall should mainly be afternoon and evening showers over higher terrain.

Afternoon and evening showers are also likely over interior parts of Southcentral Alaska throughout the period.
