Area Forecast Discussion . Updated National Weather Service Portland OR 959 AM PDT Mon Jul 6 2020

Updated Aviation Discussion.

SYNOPSIS. An upper level trough slowly moves across the Pacific NW for the start of this week. A weak cold front moves into the area on Tuesday through late Wednesday, bringing a chance of showers, cooler than normal temperatures and increasing cloud cover. A ridge of high pressure then build across the area for the latter part of the week, bringing less active weather and warming temperatures back towards seasonal normals.

SHORT TERM. Today through Wednesday . Water vapor satellite imagery continues to reveal a longwave trough over the far northeast Pacific and Pacific Northwest. Embedded within this longwave trough are a few visible perturbations which individually provide for some drizzle chances this morning along the coast and western part of the Coastal Range. These perturbations will also create an increasing chance for precipitation through Monday night along the coast, Coast Range and The Cascades. Little to no precipitation expected within Willamette Valley.

Tuesday through early Wednesday multiple models are showing a weak cold front associated with the body of the longwave trough passing across the Pacific NW, which will bring an increasing chance for showers primarily for inland areas north of Eugene. As the front moves across the CWA, precipitation chances will diminish starting from the southwest and move towards the northeast of the CWA.

Models are showing a slight ridging pattern within the 500mb heights, which means that drying trend starting on Wednesday along with a warming pattern for the middle of the week.

Overall what this means is that temperatures will be cooler than seasonal normals through the middle of the week, with temperatures in the mid 70s. Tuesday will be the exception and will likely be the coolest day for the early part of this week as areas will likely struggle to get above 70F. /42

LONG TERM. Wednesday night through Sunday . Models are in decent agreement a longwave trough will persist across the Pacific Northwest during the second half of next week and into next weekend. It appears at least a couple weak shortwave troughs dropping southeastward out of the Gulf of Alaska into the base of the main upper level trough will brush the region during this time. This will maintain our recent weather of late where widespread morning clouds should gradually give way to afternoon sunshine each day with high temperatures topping out near to slightly below average for the date. Models and their ensembles indicate there is still a lot of uncertainty on the timing and strength of these passing shortwave troughs, though. The first appears likely to impact the area sometime Thursday or Thursday night while another one could bring a stronger front into the region next weekend. However, an examination of the WPC cluster analyses of 500mb heights in the GEFS, EPS and CMCE systems suggests there is a decent chance (~45% of members) that ridging will begin to build northward into the Rocky Mountains and/or Pacific Northwest beginning over the weekend. There are certainly variations in its amplitude among those members, but the end result is that our persistent longwave trough would shift westward and result in fewer morning clouds and warmer temperatures across the region late in the weekend. /Neuman

AVIATION. Stable marine air mass remains across the region. Mix of low VFR and MVFR stratus will persist through 20Z to 22Z. Patchy drizzle is possible along the coast this am with slight chance of light rain near KAST through the afternoon. East of the coastal mtns, will see stratus lift to VFR after 18Z, with stratus gradually breaking up after 22Z.

Weak upper level disturbance off the coast will act to enhance the onshore flow today. This will slow the breakup of the stratus a bit, with stratus persisting along the coast through the day. Farther inland, low VFR stratus will reform later this evening. Late tonight into early Tuesday chances of light rain showers will increase.

KPDX AND APPROACHES . Marine stratus, with CIGS around 3500 ft, will persist this am and gradually lift through 20Z. Should see stratus break up a bit this afternoon, with scattered clouds 21Z to 04Z. After 04Z, low vfr cigs will reform. DDH/Rockey

MARINE. No changes Previous discussion follows. Surface high pressure sitting offshore will dominate the marine wind pattern this week, with generally west to northwesterly winds 5 to 15 kt. Seas mostly stay at 3 to 4 ft, thanks to a southerly swell for next few days, then a tad higher by midweek as new fetch of westerly swell arrives. /Rockey

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
