Wednesday, October 21st – Lincoln County
Summary: 63 was indeed popular yesterday as a mercury reading (see Weather Factoid below); all of our reporting stations recorded the same high temperature. The Sun never gained a strong foothold as scattered clouds irritated the sky most of the day along with very light winds. It was clear enough for decent sunset photos and the First Quarter Moon reigned over much of the night; low temps were in the 40s. Haze and fog began developing early this morning and by dawn, visibility was down to a mile or less in spots with light northeast winds doing little to dissipate it.
Past 24 Hours High/Low…
Lincoln City: 63F/52F
Depoe Bay: 63F/48F
Forecast: At least a few more basically dry days are in the crystal ball this week before a change begins around Sunday. Mixed skies are expected today, high about 60F, and light winds. Patchy fog again tonight, low near 45F. Tomorrow, foggy early but mostly sunny later with an afternoon sea breeze 10-15 mph gusting 20-25 and the thermometer stopping at 60F. Outlook is for partly to mostly sunny Friday and Saturday, and then a chance of rain Sunday through Tuesday. The mercury idles around seasonal readings with highs of 60F and lows of 45-50F.
Travel: In the Coast Range, there’s bare pavement on the highways this morning with pass temperatures near 40F; fog early, partly sunny later today and 65F. Valley destinations are expecting fog this morning, partial clearing this afternoon, the thermometer rising to 65-70F. The Columbia River Gorge forecast calls for areas of fog, becoming mostly sunny, light west winds, highs of 65-70F. For the Cascades, the passes are dry with temps 35-45F; mostly sunny today, the free air freezing level is 13,000 feet.
Marine: Benign conditions exist this morning and are expected to continue today with NE winds 10 knots and seas just 4 feet at 9 seconds. Tonight, northerlies rise to 10-15 knots gusting 20 with seas 6 feet. A large swell is projected to arrive in local waters tomorrow, reaching 12 feet at 16 seconds by afternoon, and N winds 10-15 knots gusting 20-25. Outlook is for northerlies 15-20 knots Friday with swells subsiding to 8 feet, and then SE winds 10-15 knots Saturday and Sunday, seas falling to 5-6 feet. Always check the latest Bar Reports before you venture offshore.
On the Beach… Fog early, mixed skies, surf 4-5 feet (low).
* Big surf expected tomorrow, 10-12 feet, so plan to stay away from jetties, offshore rocks and the surf line along the beaches.

Weather Factoid: Why do we use the word ‘mercury’ to describe temperature readings? The mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit of Amsterdam back in 1714 (Fahrenheit also gave us the temperature scale currently used only in the United States and Liberia while the rest of the world uses the metric Celsius scale). A mercury thermometer consists of a bulb containing liquid mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb. As the temperature changes, the mercury expands and contracts into the tube along a scale of degrees marked on the side. Efforts are underway to completely phase out this type of thermometer due to the hazardous nature of mercury. Federal and state authorities have lobbied since 2002 for bans on medical mercury thermometers. It’s already almost impossible to buy one for home use. Now, the Environmental Protection Agency, the National Institute of Standards and Technology, and environmental and industry groups are targeting industrial users of mercury thermometers. However, the term ‘mercury’ will no doubt live on in weather jargon for some time to come.
