SYNOPSIS. The weather is likely to remain rather benign over the next few days as a high pressure system offshore keeps a northwest onshore flow. Expect mostly dry weather into early next week with temperatures warming some Sunday and Monday.
SHORT TERM. Tonight through Monday . A weak shortwave seen in water vapor pictures dropping southeast off the coast of Vancouver Island Friday afternoon is expected to push a weak cold front into the region overnight. Model time height cross sections show mainly just a rather narrow band of shallow moisture arriving with this system late tonight, so will limit pops to a slight chance of showers overnight for the north coastal areas. Otherwise the resulting onshore flow should be enough to return area of clouds to the coast and northern interior late tonight and Saturday morning, with little change in high temperatures expected between Friday and Saturday.
Saturday night through Sunday night models are consistent in showing the upper heights rising some, while low level flow turns more northerly due to resurgence of a thermally induced trough of low pressure along the south Oregon coast. This will result in a decrease in the amount of diurnal cloudiness and warming temperatures. Although the upper heights begin to come back down again by Monday, 850 mb temperatures continue to warm, suggesting Monday is likely to be the warmest day of the coming week. With 850 mb temperatures expected to peak around 18C Monday, could see some inland valley high temperatures reaching near 90F.
LONG TERM. Monday night through Friday . Models are in general agreement showing the more or less zonal flow early next week, evolving into a trough over the region, before shifting east of the Cascades at the end of the week. While the ultimate depth of the trough is not well agreed upon, there is enough uncertainty in the strength to include a small chance of showers over parts of southwest Washington Wednesday and Thursday. Otherwise expect temperatures to run a little below normal through the middle and latter parts of the week.
AVIATION. Conditions remain predominately VFR as the air mass continues to stabilize as high pressure builds in across the area. Predominately VFR across the area with mostly clear skies through Saturday. The only exception will be along the coast this evening as onshore flow will persist. Expect MVFR cigs to develop near KAST after 07Z Saturday along with a slight chance for showers. KONP has the potential for MVFR cigs to develop around the same time but, confidence is low at this time. After 16Z Saturday look for VFR conditions to return along the coast and persist across the area through Saturday.
KPDX and APPROACHES . Predominately VFR with mostly clear skies through Saturday. /42
MARINE. High pressure will build across the waters through early next week with thermal low pressure over the far south Oregon coast. North winds 15 to 25 kt with gusts up to 30 kt and seas 7 to 10 feet at 12 seconds. Highest gusts of 30 kt possible south of Cascade Head. Gusty northerly winds and steep seas will continue through much of the upcoming week, therefore have issued a small craft advisory for winds and seas starting Saturday for all waters. /42
PQR WATCHES/WARNINGS/ADVISORIES. OR . None. WA . None. PZ . Small Craft Advisory from 11 AM Saturday to 11 PM PDT Sunday for coastal waters from Cape Shoalwater WA 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.
