Area Forecast Discussion . UPDATED National Weather Service Portland OR 1015 AM PDT Sun Jul 12 2020

Updated aviation discussion

SYNOPSIS. Aside from a chance for light rain today, expect primarily dry conditions with temperatures remaining near to slightly above average for much of the next week.

SHORT TERM. Today through Wednesday . Weak lift and shallow moisture just ahead of a weakening front continues to shift southeastward into northwest Oregon and southwest Washington early this morning. Doppler radar has picked up on lots of light returns spreading onto the north coast early this morning. Measurable rain has been rather limited thus far, but more and more stations should measure as the low level atmosphere saturates. Expect off and on light rain this morning along the coast and west slopes of the Cascades north of a line extending between Newport and Mt Hood. Confidence more than a few sprinkles will fall in the Portland/Vancouver metro is still low given the difficulty with which some our typically wetter spots have had measuring rain thus far, but radar trends suggest at least a slight chance mention seems prudent. Between daytime heating, increasing northwesterly to northerly flow and building 500mb heights across the area, expect clouds and rain chances to gradually dissipate today.

Shortwave ridging building across the northeast Pacific should then then result in 500mb heights rising further Monday into Tuesday and Wednesday across the region. This should allow temperatures to warm back to seasonal averages to begin the week before climbing several degrees above average towards the middle of the week. Low level onshore flow will keep the coast cool with breezy winds each afternoon and evening. Expect morning clouds to largely be confined to the north coast and lower reaches of the Columbia River with mostly sunny to sunny conditions elsewhere. /Neuman

LONG TERM. Wednesday night through Sunday . Upper level ridging will continue to reside over the northeast Pacific and Four Corners regions. This will likely maintain weak upper level troughing over the Pacific Northwest. Low level onshore flow will keep temperatures near to slightly above average for the date. Most model solutions and climatology suggest the bulk of the CWA will likely remain dry. However, there are enough ensemble members that suggest the region could be clipped by a weakening front Thursday or Friday that have kept slight chance to low end chance PoPs across our northern zones during this timeframe. It should be noted that the EC and many of its ensemble members have the pattern becoming a bit more amplified late in the week into next weekend. So while they are a bit more bullish on cooling and precipitation chances late in the work week, they also rebound a shortwave ridge over the Pacific Northwest late in the weekend into early next week. This could potentially bring some of our warmest weather of the year during this period, but confidence in this occurring remains low at this point. /Neuman

AVIATION. A weak disturbance will continue to move across the forecast area this morning resulting in local MVFR cigs inland along with a few sprinkles. Expect lower cigs inland to linger through ~20Z before lifting and scattering this afternoon. The exception will be the central coast where local IFR conditions may linger through ~22Z. High pressure will build into the region this afternoon resulting in widespread VFR conditions and gusty northerly winds this afternoon and evening. There is a chance for some patchy IFR cigs along the coast tonight, but confidence is low.

KPDX AND APPROACHES . Expect local MVFR cigs to stick around through ~20Z with some light sprinkles possible. Otherwise, stratus will lift and scatter this afternoon for VFR conditions under mostly clear skies. Expect VFR to persist through Monday, with gusty northwest winds possible between 23-05Z. /64

MARINE. The remnants of the weak cold front that passed through overnight continues to bring scattered rain showers throughout the northern Oregon/southern Washington waters. Southwesterly winds, which brought gusty conditions to the northern inner waters, will shift to a northerly flow Sun morning as high pressure develops over the eastern Pacific. This high pressure and associated wind shift will kick start a prolonged period of gusty northerly winds through the next several days. The northerly flow around the high pressure is compounded by an inverted thermal trough that is forming over California. This thermal trough will increase the pressure gradient, especially through the central Oregon waters which will aid in intensifying winds. Starting Sun night and persisting through the middle of the week, expect winds 10 to 15 kt with gusts to 25 kt. At this time, expecting the advisory levels winds to be isolated to the the central waters so a Small Craft Advisory has been issued for those areas.

While winds are expected to increase, seas too will be impacted. The general swell is stemming from the northwest at 4 to 5 ft with a period of 7 seconds. Significant wave heights, aided by the addition of the wind driven wave, may become square with waves building to 5 to 7 ft with a 7 to 8 second period. These conditions are expected to persist through the work week. -Muessle

PQR WATCHES/WARNINGS/ADVISORIES. OR . None. WA . None. PZ . Small Craft Advisory from 5 PM this afternoon to 5 AM PDT Tuesday for coastal waters from Cascade Head OR to Florence OR out 60 NM.

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.
