Updated aviation and marine discussions

SYNOPSIS. Mild and mainly dry Spring-like weather will hold through early Thursday before a series of storm system bringing a return to valley rain and mountain snow late in the week into the weekend.

SHORT TERM. Tonight through Friday . What remains of a stalled, dying front continues to spread out across the northwestern part of the CWA tonight. Weak surface ridging develops through Wednesday, which will maintain dry conditions across the CWA along with a warming trend which will result in high temperatures for inland valley locations reaching the upper 50s to low 60s, coastal locations and the Cascades warming into the upper 40s to mid 50s through early Thursday.

Over the next few days a trough coming from the Aleutian Islands will slowly progress into the eastern Pacific Ocean and by Thursday afternoon will start to impact our area. The key features through the latter part of this week will be the trough and a weak to low end moderate atmospheric river. The trough and associated front will turn this atmospheric river flow south to north, rather than the typical west to east flow. Guidance does have total QPF values of 2 to 3 inches by Friday night for areas along the Coast Range with total QPF values lowering further east with inland valley locations picking up between 0.50 and 0.25 inches and the Cascades seeing less than 0.25 inches by Friday night. Given the south to north orientation, the likelihood of hydrological impacts remain low at this time. However, areas like the Grays and Nehalem rivers will be closely monitored given that some areas still have a snow lingering in the upper elevations. /42

LONG TERM. Friday night through Monday . Friday night models have the upper level trough axis over or past the Cascades. The cooler air behind the front will drop snow levels but the bulk of the precipitation looks to be done by that time. Saturday shortwave ridging looks to take place which will lower precipitation chances but given that there is some uncertainty between the operational models have chosen to not deviate much from the NBM which keeps a chance of precipitation across the CWA. As Sunday approaches a colder low looks to dive down from the Gulf of Alaska towards the Pacific Northwest, which will bring cooler temperatures, lowering snow levels with valley rain and mountain snow through Monday. /42

AVIATION. High pressure will continue over the region tonight into tomorrow, bringing calm to light and variable winds and mostly clear skies. This setup will be ideal for areas of fog and low stratus to develop later tonight, especially after 11Z Wednesday. It appears fog will be a little more widespread than last night, with dense fog possible at times. All TAF sites have the potential for fog tonight into Wednesday morning, but KHIO/KUAO/KEUG appear to have the best chance. Any fog or low clouds that develop overnight should last well into Wednesday morning, and perhaps into early afternoon over the southern Willamette Valley. Skies should eventually become mostly clear again once fog and low stratus scatters out between 17-21Z Wednesday.

KPDX AND APPROACHES . Nearly calm winds and mostly clear skies will continue through much of tonight, before chances for fog and/or low stratus increase after 11z Wednesday. Dense fog is not expected at the terminal at this time, but cigs around 800 ft are becoming more likely beginning around 12Z Wednesday. -TK

MARINE. Buoy observations late Tuesday evening showed seas still hovering around 12-13 ft, which is several feet higher than what wave guidance has been suggesting. This is due to a northwest swell that is taking longer than expected to fall below 10 ft. Therefore, the Small Craft Advisory has been extended for all waters through tonight before dropping off after sunrise when seas should finally fall below 10 ft. A Small Craft Advisory has also been extended through 10 am PST Wednesday for the main channel of the Columbia River Bar, due to seas running higher than expected and Wednesday's morning strong ebb likely resulting in seas to 10 ft with breakers possible.

Conditions deteriorate Thursday as a strong but slow moving cold front approaches. Moderate to high potential for strong southerly gales, along with seas building back to 17 to 22 ft. A Gale Watch has been issued for all waters beginning Thursday morning and continuing through mid Friday morning. Winds and seas will drop back a bit on Friday afternoon, but unsettled weather will continue into the coming weekend. -TK/Weagle

PQR WATCHES/WARNINGS/ADVISORIES. OR . None. WA . None. PZ . Gale Watch from Thursday morning through Friday morning for coastal waters from Cape Shoalwater WA to Florence OR from 10 to 60 NM.

Small Craft Advisory until 7 AM PST Wednesday for coastal waters from Cape Shoalwater WA to Florence OR out 60 NM.

Gale Watch from Thursday morning through Friday morning for coastal waters from Cape Shoalwater WA to Florence OR out 10 NM.

Small Craft Advisory until 10 AM PST Wednesday for Columbia River Bar.
