________________

Sorry, but no winner this week. Here is my weekly weather quiz question for the last time. What is “Popcorn Convection?” Here is the correct answer. Popcorn Convection is slang for showers and thunderstorms that form on a scattered basis with little or no apparent organization, usually during the afternoon in response to diurnal heating. Individual thunderstorms typically are of the type sometimes referred to as air-mass thunderstorms: they are small, short-lived, very rarely severe, and they almost always dissipate near or just after sunset. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

Advisories:

A Blue-Green Algae warning continues for Dexter Reservoir, Dorena Reservoir, and Fern Ridge Reservoir.  Water monitoring has confirmed the presence of blue-green algae that can produce toxins, state public health officials said. The algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided according to the authorities.

________________

An upper level high pressure ridge shaded “Arch” shape has taken over our weather for a short while, then another upper level low pressure trough will move in to replace it. Autumn begins at 1:44 PM Friday September 22nd, so Summer is nearly over.

________________

The Grass Pollen Count is listed as Low at 2 and Tree pollen is Absent at 0 as of 8/31/13 according to Oregon Allergy Associates. The Season is over.

Advisories:

A Blue-Green Algae warning continues for Dexter Reservoir, Dorena Reservoir, and Fern Ridge Reservoir.  Water monitoring has confirmed the presence of blue-green algae that can produce toxins, state public health officials said. The algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided according to the authorities.
