SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)

An upper level low currently over Bristol Bay will slowly weaken and move into the eastern Gulf over the next 72 hours. Through Monday afternoon, upper level shortwaves will rotate into the coast and some interior areas, bringing periods of light rain showers. Overall precipitation chances and magnitude decrease as you move inland. Along the coast and Kodiak, expect more frequent rain due to upslope and onshore flow. Colder air will slowly wrap into the low, so expect a slight cooling trend this week with lows around freezing for cooler spots by Tuesday morning. As we move into Tuesday afternoon and Wednesday, the low will depart farther to the east, leading to more widespread clearing, and colder morning lows. There is a weak trough expected to move into the region on Wednesday, but there remains uncertainty as to its overall shape and speed as it moves from the AKPen and into the Gulf and/or Kenai Peninsula. It does look like rain and mountain snow will return by late Wednesday.

AVIATION

PANC...VFR conditions will persist through the TAF period. Very light drizzle will remain possible for much of Sunday while the remnants of a front lift up Cook Inlet and the terminal remains downstream of broader low pressure system over Southwest Alaska. Light and variable winds will continue into Monday with the threat of any LLWS coming to an end this afternoon as southeasterly winds at around 2000 ft finally weaken.
