SYNOPSIS. Another chilly, fall day is in store as showers continue before tapering off tonight. A weak front will approach the coast Wednesday and move inland on Thursday. A warming trend is expected by the weekend as dry weather is likely through at least Monday.

SHORT TERM. TODAY THROUGH THURSDAY . Water vapor satellite imagery early Tuesday morning reveals a deep upper level trough moving over the region. Widespread convective showers within an unstable air mass under the upper trough are spreading across the entire CWA this morning. The few lightning strikes that have been observed have mainly been confined to near the coast. The trough axis, along with the coldest air aloft, will slide east of the Cascades this morning leaving the area under northwest flow aloft. Expect rain showers to continue through this afternoon, and then taper off from west to east tonight. A slight chance of thunder will continue today, mainly along the coast this morning before shifting inland this afternoon. Temperatures will remain cool as many locations will struggle to reach 60 F today. Snow levels today are expected around 5,500 feet.

The next weather system to approach the coast will stem from low pressure in the Gulf of Alaska on Wednesday. Precipitation chances will increase along the north Oregon and southwest Washington coast on Wednesday. Breezy southerly winds will also be likely along the north Oregon and south Washington coast where gusts up to 45 mph will be possible near beaches and headlands. Rain chances will then increase and spread further inland on Thursday as an upper level shortwave moving toward Vancouver Island drives a weak front across the Pacific Northwest. The best chances for rain on Thursday will be across the northern zones, while much of the southern Willamette Valley may remain fairly dry. Rainfall amounts will generally be light, except for the north coast and Willapa Hills. Ensemble means and NBM suggest that Astoria will likely see 0.5 to 1.0 inch of rainfall over a 36 hour period. Daytime temperatures will warm slightly each day through the middle of the week to near normal by Thursday. /DH

LONG TERM. THURSDAY NIGHT THROUGH MONDAY . A weakening shortwave moving across the region Thursday night may support a few lingering showers into Friday morning. Building high pressure behind the front is expected to bring drier weather to the area Friday and into the weekend. More northerly low level flow should keep temperatures relatively cool again on Friday. Models are in decent agreement that an upper level ridge will shift over the region by Saturday and build through Sunday. Temperatures are expected to warm into the 70s over the weekend. Monday should see similar conditions. NBM guidance suggests PDX has a 35% chance of reaching 80F both Sunday and Monday. Overall, the start of October should be dry, relatively warm, and a good weekend to get outside. /DH

AVIATION. An unstable and showery weather pattern will gradually ease later today and tonight as high pressure builds into the region. This will result in predominantly VFR conditions areawide through 12z Wednesday. With that said, conditions will likely temporarily drop into MVFR thresholds and even IFR conditions in a few isolated instances when an intense shower rolls over a site today. Will likely handle these possibilities with tempo groups. In addition, clearing skies tonight may allow fog and low clouds to form in spots towards 12z Wednesday. This may create at least some pockets of LIFR, IFR and MVFR conditions forming between 06-12z Wednesday.

Finally, a few thunderstorms have been present near the Oregon coast this morning. These should dissipate between 12-15z Tuesday. However, a slight chance of thunderstorms will likely develop this afternoon across the Willamette Valley, particularly east of Interstate 5 with KPDX and KTTD standing the highest chance of getting a short lived thunderstorm.

KPDX AND APPROACHES . An unstable and showery weather pattern will gradually ease later today and tonight as high pressure builds into the region. This will result in predominantly VFR conditions through 12z Wednesday. Clearing skies this evening may allow fog or low clouds to form in spots towards 12z Wednesday. This may create at least some pockets of LIFR, IFR and MVFR conditions forming between 06-12z Wednesday. Finally, there is a 10-20% chance of a short lived thunderstorm impacting the terminal between ~20Z Tuesday and 02z Wednesday. /Neuman

MARINE. A cool and showery weather pattern continues across the waters early this morning. This is resulting in ongoing isolated thunderstorms across the waters. These more intense showers and thunderstorms should weaken considerably over the next couple of hours as the upper level storm system supporting these storms slides into the Rocky Mountain states. Surface high pressure building into the waters later today should result in decreasing winds and allow seas to subside.

A warm front will then push across the northern waters late Tuesday night into Wednesday. This will result in winds increasing across the waters, particularly off the north Oregon and south Washington coast. Winds may temporarily back off later Wednesday before strengthening ahead of a cold front dropping southeastward Wednesday night. Most model guidance suggests high end Small Craft Advisory level wind gusts of 30 kt will develop across our northern waters. However, some high resolution models suggest the potential for low end Gale Force wind gusts of 35 kt to develop over the waters off the Columbia River Bar and south Washington coast Wednesday into Wednesday night. Given confidence is relatively low in these stronger winds materializing, will let the day shift evaluate the need for a Gale Watch if more and more model guidance suggests this will become likely.

Surface high pressure will build across the northeast Pacific late Thursday into early next week. This will bring relatively benign winds and allow seas to subside down into single digit values during this period.

Finally, a large westerly swell of 15-20 ft continues to move across the waters early this morning. Expect this swell to slowly subside today with seas likely falling below 10 ft on Wednesday. Seas will then hover around 10 ft late Wednesday through Friday before subsiding more solidly into single digit values over the weekend. /Neuman
