Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 443 PM AKDT Fri Jul 19 2024

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: This afternoon through Monday evening)...

The warmer and drier weather has arrived today and is expected to persist through the weekend. The only caveat is that mesoscale easterly waves will move near or over Southcentral this weekend.
While most areas will stay dry, there is a chance of isolated thunderstorms over the Copper River Basin and Mat-Su Valleys Saturday with potentially a little more coverage on Sunday with warmer temperatures and more instability expected. Depending exactly where exactly the mesoscale waves track, the Chugach and Kenai Mountains, including potentially the Anchorage Hillside, and along either side of the Kenai Mountains, have a chance to see an isolated storm for Sunday afternoon and into the evening.
However, confidence is low and there is uncertainty with the tracks of the mesoscale waves. The warmest locations this weekend will continue to be the Copper River Basin and Susitna Valley were temperatures could touch 80 degrees. The warmer and drier weather comes to an end on Monday as a more powerful easterly wave from Yukon, Canada moves westward over the Copper River Basin initially, and then the rest of mainland Southcentral through the day.
.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3)...

The axis of a high pressure ridge is spans from the eastern Aleutians to the Southwest coast this afternoon. An occluded low is centered over the western Aleutians with its triple point located near Nikolski. A long fetch of subtropical moisture is expected to spread across the Aleutians and into the Bering Sea over the next few days.

Precipitation is moving through the central Aleutians and Bering Sea, but later this evening, precipitation will lift into the northern Bering and spread east to the Pribilofs and the eastern Aleutians. Precipitation should remain steady and light, with smaller moderate to heavy bands between Unalaska to the Pribilofs by Saturday morning. The low will slowly linger in the Southern Bering Sea while its front will slow down considerably as it continues across the eastern Bering Sea and the Alaska Peninsula.
The slow progression will contribute to a total rainfall for St Paul to be around an inch from tonight through Sunday afternoon.
Elsewhere along the Aleutians could expect roughly half inch to an inch storm total rainfall. Winds along the front are expected to be between 15 to 25 mph with gusts to about 30 to 40 mph.

Across Southwest Alaska, skies will gradually clear for this weekend as the ridge moves east. Afternoon showers will be possible through the weekend from southern Bristol Bay to the foothills of the western Alaska Range as embedded easterly shortwaves round the periphery of the a Gulf low. Winds are expected to be light across Southwest as the upper level flow weakens. Convective potential will increase each day, with isolated thunderstorms possible Sunday afternoon.

.LONG TERM FORECAST (Days 4 through 7: Tuesday through Friday)...

With some small adjustments with the position and strength of the omega block over Mainland Alaska will come from the West through the forecast period. One upper level low center exits the Gulf of Alaska Wednesday with little effect to the high, moving onshore into Canada by midweek. The other low in the Bering gathers support from the Arctic and begins its move over the West Coast.
Shortwaves around the Bering low add increased instability for the Western half of the state. Longer term rainfall continues across the Aleutians and Bering through the end of the workweek. Forecast model confidence remains higher for the Interior features, and slightly less elsewhere. Periods of locally heavy rain spreads over Southwest Alaska and the Alaska Peninsula for late Tuesday and is sustained more over the West as the areal coverages expands across Kodiak Island and Southcentral Alaska through Prince William Sound by Friday. Locally heavier rains will also extend inland to the Alaska Range during the forecast.

The Eastern Interior and along the Alaska Range will see warmer temperatures as the bulk of the surface high holds in place through the Yukon Valley. A higher risk of occasionally heavier showers and thunderstorms through the Copper River Valley are possible through the forecast period.
