SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)

This afternoon, a large upper-level low in the northern Gulf will continue drifting eastward, stalling southwest of Yakutat and lingering in-place before dissipating Friday morning. Light, mixed precipitation will continue across parts of the Copper River Basin, Thompson Pass and the Gulf coast from Prince William Sound and eastward, before tapering off later this afternoon.

Overnight low temperatures across Southcentral will be much colder over the next few days, dipping into the teens and 20s in most spots for Thursday morning, and into the single digits for portions of the Copper River Valley if skies remain clear. Low temperatures overnight Thursday into Friday morning will likely be even colder, with widespread teens for locations away from the immediate coast and single digits to near zero degrees for locations in the Copper River Basin.

Conditions favorable for fog will develop in select locations where saturated ground and clearing skies permit temperatures to rapidly reach the dewpoint. Drier and cooler conditions persist through Friday as an upper ridge strengthens over Southcentral from the west. Further out, the front of a strong Bering low will increase chances for rain across Kodiak and the southeastern Kenai Peninsula for Saturday morning, then lower chances across interior Southcentral by Saturday afternoon.

LONG TERM FORECAST (Days 4 through 7: Sunday through Wednesday)

Key Messages:

* A series of strong storms continue to move across the Bering Sea and into Alaska from Sunday through the middle of next week, bringing strong winds and heavy precipitation.

* Confidence is low to medium with regards to impacts. Strong onshore winds and elevated coastal water levels are concerns for Southwest Alaska, especially on Sunday and Monday.
