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. VFR prevails across much of the forecast area this afternoon, as a stalled front and the last vestiges of this morning's low clouds dissipate across SW WA/NW OR. Skies tonight will start off mostly clear with some passing high clouds. With winds nearly calm, expect areas of fog to develop in the valleys tonight, perhaps a little more widespread than last night. Any fog or low clouds that develop overnight should last well into Wednesday morning, and perhaps into early afternoon for some areas.

KPDX AND APPROACHES . VFR this evening, with an increasing chance of fog overnight after 06z. Roughly a 40 percent chance of IFR/LIFR conditions between 03/12z and 03/16z. Will likely handle this with BCFG in the 00z TAFs. Weagle

MARINE. Stalled front across the northern waters has more or less dissipated over the last few hours. While winds are fairly benign, seas are not - residual W-NW swell has pushed seas into the mid-teens across our coastal waters. Wave models suggest seas should subside below 10 ft by midnight tonight, so existing SCA looks to be in good shape. Strong morning ebbs may require another SCA for rough Columbia river bar Wed morning, but will hold off for now as our bar forecast model shows marginal SCA conditions and it tends to over-forecast.

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 will likely be needed soon, especially for the outer waters. Winds and seas will drop back a bit on Fri, but unsettled weather continues into the coming weekend. Weagle

PQR WATCHES/WARNINGS/ADVISORIES. OR . None. WA . None. PZ . Small Craft Advisory until midnight PST tonight for coastal waters from Cape Shoalwater WA to Florence OR out 10 NM-Columbia River Bar-Coastal waters from Cape Shoalwater WA to Florence OR from 10 to 60 NM.
