Here is my weekly weather quiz question. What is a “Banner Cloud?” The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) moves up toward the coast allowing for more inland warming. The graphics for days 1-3 show the weak cool front that passes just north of us cooling temperatures a bit. The graphics for days 3-7 show the next frontal systems approaching the Pacific Northwest and trying to move in Friday and next Monday.

Enjoy the 4th of July, but please be careful with any fireworks and don’t drink and drive a motor vehicle or a boat.

Advisories:

•  A Health Advisory has been issued for Lake Billy Chinook, located 12 miles west of Madras in Jefferson County. Water monitoring has has confirmed the presence of Blue-green Algae and the toxins they produce. These toxin concentrations ca be harmful to humans and animals. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area. Drinking water directly from these areas of Lake Billy Chinook at this time is especially dangerous. Oregon public health officials advise campers and other recreational visitors that toxins cannot be removed by boiling, filtering or treating water with camping-style filters.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.

An Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows) will slowly migrate across Oregon. Marine clouds cooled us a bit Saturday. We warmed up a bit again Sunday. An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) moves up toward the coast allowing for more inland warming. The graphics for days 3-7 show the next frontal system approaching the Pacific Northwest and trying to move in Tuesday night into Wednesday. The 4th of July still looks bright and dry with temperatures in the mid to upper 80s. That’s a bit above normal.

Here is my weekly weather quiz question for the last time. What is the “Backwater Effect?” Here is the correct answer. The Backwater Effect is in hydrologic terms, the effect which a dam or other obstruction has in raising the surface of the water upstream from it. I’ll have a new weekly weather quiz question for you starting Monday.  The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

An Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows) will slowly migrate across Oregon. That means we’ll slowly warm up a bit. The graphics for days 3-7 show the next major frontal system will move over the Pacific Northwest Monday through Tuesday and another one approaching Saturday. So far, the 4th of July looks dry with temperatures near 80. That’s just about normal.

Advisories:

•  A Health Advisory has been issued for Lake Billy Chinook, located 12 miles west of Madras in Jefferson County. Water monitoring has has confirmed the presence of Blue-green Algae and the toxins they produce. These toxin concentrations ca be harmful to humans and animals. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.Drinking water directly from these areas of Lake Billy Chinook at this time is especially dangerous. Oregon public health officials advise campers and other recreational visitors that toxins cannot be removed by boiling, filtering or treating water with camping-style filters.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.
