SYNOPSIS

Key Messages:

- Very warm to hot temperatures this afternoon with sunny skies.

- Slightly cooler but still mild for much of the panhandle on Wednesday with increasing mid to high level clouds.

- Next front with light rain pushes into southern panhandle later Wednesday afternoon, then lifting north through the night.

- Cooler with rain showers for the end of the work week.

LONG TERM.../Friday through Sunday/

Upper level off-shore flow shifts to on-shore flow through the day Friday as the upper level low moves south along the coast, out of the area. This then allows a ridge to take its place over the panhandle, however, both the magnitude and timing are not conclusive between ensembles. This has created much uncertainty in the exact timing of any precipitation for the weekend, but the ridging building over the panhandle on Friday and Saturday is likely to bring a drying trend with showers on Friday diminishing through Friday night into Saturday. Despite the drier conditions, skies are likely to be cloudier due to the moisture coming off the ocean.

Ensembles indicate a upper level shortwave moving through the area on Sunday. This energy is likely to bring rain showers back to the panhandle on Sunday. This energy could also bring increased winds to the panhandle on Sunday, specifically the southern and central inner channels and land areas.

AVIATION.../through Wednesday afternoon/

VFR conditions expected through most of Wednesday. A front lifting north will bring lowering cloud decks from PASI over to PAPG and on south on Wednesday. Rain showers could lower CIGs down to MVFR by late afternoon for PAPG, PAWG and especially PAKT and PAKW. For TAF sites further north, just expect increasing high clouds through Wednesday afternoon. Winds will generally be less than 10kt through the period. Occasional higher gusts possible during the afternoon hours across the north Wednesday.

MARINE

Outside (Gulf and Coastal Waters): A low pressure system is currently west of our coastal waters, and will move east late Tuesday night into Wednesday morning. The low is expected to track near Haida Gwaii, so the highest winds up to 20 kts and waves up to 10 feet will occur across our far southern waters.

Inside (Inner Channels): Winds today have been fairly weak in the inner channel. A low pressure system currently in the Gulf of Alaska will approach our area increase the winds in east-west channels (e.g. Cross Sound, Fredrick Sound, and Sumner Strait). The low is fairly weak, so winds are expected to remain under 15 kts, but may approach 20 kts and waves of 3 feet as the associated front moves through. Behind the front, high pressure is expected to set-up, and lead to generally onshore flow.
