SYNOPSIS
Key Messages:
- A weak disturbance will slide south through SEAK Monday, bringing a chance of showers.
- Quiet weather returns for Tuesday through Thursday, with more sun and dry conditions expected. Northerly outflow winds expected to increase through the inner channels and outer coastal waters.
- A return to a wetter pattern expected by late week into next weekend.
LONG TERM.../Thursday through Saturday/
Nothing much to speak of in the middle of the week as a large ridge parks itself over the Gulf. A change in pattern is on the horizon, however, as a front makes its way into the panhandle late Friday, dropping rain through Saturday. This does not have the appearance of a particularly heavy or concerning rain system, but it will end the nice weather. Cold air ahead of the front has the snow level pretty low, but the change to southerly flow and slow arrival of moisture will likely eliminate the confluence of factors necessary for some snow to mix in for low elevation spots early at event onset. Expect a rain event, but as this system gets in range for high res models, the rain/snow line will be something to watch.
AVIATION
/ through Monday night / Weakening frontal band or trough is moving slowly east though southeast alaska. Ceilings above 3500 feet are east of roughly a Kake Klawock line although patchy fog around the Petersburg region again that had visibilities under 1/2 mile briefly west of line and northward to about the Icy Strait Corridor this morning was ceilings of 1000 to 2500 feet and a few pockets of 600 to 900 feet height. Isolated showers are mixed into the clouds as well. A clearer hole further behind the trough in Yakutat, allow a lower patch of clouds with fog also down to 1/2 mile or less develop this morning as well with visibilities shift around.
A second pocket of clouds and possibly rain is expected to push into the norther gulf and track to the northern panhandle later part of Monday. The flow pattern may direct this energy primarily Southeast along the outer coast of the panhandle.
