SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)
Isolated showers and mid-level clouds will persist through the afternoon across Southcentral as clear skies and moist southeasterly flow have led to surface heating and convective activity. Radar returns indicate persistent activity over the Caribou Hills east of Ninilchik, and increasing activity north along the Kenai Peninsula, the Chugach Front range, and the Talkeetna Mountains. Strong southeasterly gap winds for Turnagain Arm, Knik River Valley, and Copper River Valley will develop this afternoon through late tonight with gusts up to 35 mph possible.
A shortwave trough off a low over Southeast Alaska continues to sweep across Southcentral this afternoon. While it has brought persistent rain to Valdez, Cordova and the southern Copper Basin, the northern Copper Basin has remained slightly drier under persistent cloud cover. On Wednesday the residual trough will then elongate and get pulled southward through the day with scattered showers redeveloping over the higher terrain drifting east over Anchorage and Cook Inlet in the east- northeast flow aloft.
As a low sweeps across the Alaska Peninsula on Wednesday it passes into the southern Gulf, pulling the remnant trough to the south along with it. Drier and warmer conditions are expected for Thursday and Friday with most locations reaching high temperatures in the mid to upper 70s, with near 70 for Homer, Seward, and Valdez, and high 60s for Kodiak and Cordova.
AVIATION
PANC...The southeasterly Turnagain Arm winds will persist through the evening and then lighting up, though not entirely end, overnight. These winds are expected to increase again Wednesday afternoon, but not be as strong as this afternoon and evening. There remains a chance for a shower to encroach on the terminal this evening, but the more likely timeframe for rain is after midnight through Wednesday morning as an easterly wave moves into the area. Even with the rain, VFR conditions are expected to persist through the TAF period.
