An Upper level High Pressure ridge, as you can see by the shaded area off the coast and the little arrows inside,  will keep our weather dry through Christmas day. The next cold front will change the weather back to wet over the weekend. If you’re looking for a white Christmas you’ll have to look somewhere else.

Here’s my new weekly weather quiz. Why can the mercury never drop below -40 degrees F? Please place your question as a comment on this page. The first person to answer correctly wins one week of free personalized forecasts tailored to your needs.

A very strong cold front is moving through Oregon. Behind it is colder air aloft which will lower the snow levels. That means more snow for the mountains. Great for skiers and the snow should stay in the mountains and leave the rest of us alone.

Nobody correctly answered this week’s weather quiz question. What do “lake breezes” have to do with spiders? Here is the answer. In the summer of 1991, Chicago lake shore high-rise residents had to contend with an invasion of spiders. These arachnids, or “araneus serricatus,” may actually fly in across Lake Michigan. They are believed to spin little parachutes and waft across the lake on brisk easterly breezes, coming to rest on the tall buildings. The wind also blows smaller insects into the spiders’ new webs, providing a steady diet that enables some spiders to grow to be an inch across.

There will be another weekly weather quiz question starting next Monday.  The first person to answer correctly will win a free week of personalized forecasts tailored to your needs. Good luck.
