Thursday, August 27th – Lincoln County
Summary: Try as it might, the late-Summer Sun just couldn’t do a heck of a lot to penetrate the marine cloud layer yesterday. But there were a few short-lived sunbreaks, highs rose into the 60s and the breeze was light southwest. Following sunset, the waxing gibbous Moon played peek-a-boo through the diaphanous overcast, the wind fell calm and lows dipped to around 50F. Fog developed along the beaches after midnight with even a smidge of drizzle reported. At daybreak, the fog, haze and low clouds were thinning, and a breeze drifted along from the northeast.

A Special Weather Statement has been issued by the National Weather Service for all of Northwest Oregon including the Central Coast. A big change in the weather is coming as substantial rain is expected over the area late this week and this weekend. This could be the most rain we’ve seen since March. Rainfall accumulations through the weekend could exceed an inch or possibly even 1.5-2.0 inches along much of the coast with 0.75 to 1.5 inches in the Cascades and 0.5 inches or higher in the valleys. The rain will be produced by a low pressure system currently located off the coast as it moves onshore and inland into the Pacific Northwest. This system will be picking up substantial moisture, some of it of tropical origins, and spreading it across our area beneath a 110 knot upper level jet. The first main period of the heaviest rain will be Friday night into Saturday, but a second system will add to the rainfall totals Saturday night into Sunday.
If all of this comes together as expected, this rain will likely ease the dry fire conditions dramatically over Northwest Oregon for at least the next week or two. The rain will cause problems for those with outdoor activities planned for this weekend. Snow levels will generally stay above 8,000 feet, but climbing area mountains is not recommended. In addition, oils that have built up on roadways during the extensive period of dry weather this Summer will cause the roadways to be extra slippery during the first part of the coming rain event. Be sure to slow down and use caution, and leave extra space between you and the vehicle ahead of you.
Forecast: It appears we’ll squeak out another dry one today with mixed skies, highs around 65F and light winds. The transformation becomes apparent tonight when clouds thicken and a chance of rain develops; lows near 55F. The first shot of rain arrives tomorrow, maybe a quarter inch, and southwest winds blow 5-15 mph gusting 20. Outlook is for the brunt of the storm to hit the Central Coast tomorrow night into Saturday with the most precipitation, an inch or better, and the strongest winds, sou’westers gusting 25-30 mph. Showers of varying intensity continue Sunday through Wednesday but with some sunbreaks, the mercury rises to 60-65F during the day and falls to 50-55F at night.
Travel: In the Coast Range today, partly sunny with 75-85F. Valley destinations are expecting a few clouds and a high of 85F. The Columbia River Gorge forecast calls for mostly sunny skies, light south wind, temps near 85F. For the Cascades, there’s bare pavement on the highways this morning, temperatures are 50-55F; partly cloudy, the free air freezing level is 12,000 feet.
Outdoor burning remains banned throughout most of Northwest Oregon including State Parks and ocean beaches.
Marine: It’s the calm before the storm this morning; winds SE 5-10 knots and nearly-flat swells 3 feet at 16 seconds. Expect southerlies today, tonight and tomorrow 5-15 knots with swells 3 feet building to 5 feet. Outlook is for rough conditions Saturday as S winds rise to 20-25 knots gusting 35 and combined seas build to 8 feet. Sunday, S winds 15-20 knots, seas 9-10 feet, and Monday a SW breeze 20-25 knots with 8 foot choppy seas. Always check the latest Bar Reports before you venture offshore.
Notice to Mariners… The dredge m/v Yaquina is scheduled to be working in the Yaquina Bay entrance and harbor from today, August 27th, through next Wednesday, September 2nd. The dredge monitors VHF Channels 13 and 16. Also, Oregon State University will deploy a research buoy from September 3rd through September 12th at approximate position 44-29-30.000N, 124-25-10.000W, about 16 nautical miles west of Seal Rock. Dates are tentative but the deployment will end during the month of September 2015. The buoy is yellow, 5 feet in diameter, and will display a yellow flashing light with a Fl Y 4s flash characteristic. Mariners are requested to provide 500 yards clearance from the buoy due to its sensitive equipment.
On the Beach… Sun and clouds, light breeze, surf 1-3 feet (low).
* Beach fires are prohibited under the current open-burning ban.
