The jet stream shows a high pressure ridge (“arch” shape) has been aiming the airflow straight South toward the Pacific Northwest. The ridge is slowly moving Eastward which will allow our temperatures to moderate a bit. A weak disturbance will slip in bringing at least a slight chance of rain. Yet another ridge will start to build in and that will keep us under a relatively calm weather pattern. Remember that, particularly this time of the year, often when it’s not raining it is usually fogging.

“Punxsutawney Phil” did not see his shadow Wednesday. That is supposed to give a forecast of an early spring. I surveyed reports from 15 groundhogs across the country (most of them in the Northeast and one in Ontario, Canada) and 10 did not see their shadows while 5 did. That means 10 predicted an early spring and 5 said we’ll see 6 more weeks of winter. What does all of this mean? Not much, but it is a diversion from the stormy weather across over half of the United States.

Congratulations to Buddy McKinley this week’s weather quiz winner. Here’s the question he correctly answered. Nor’easters have been causing a lot of trouble this Winter season. Just define the term “nor’easter” to win a week of free forecasts. You can go back to his posted comment answer, but I’ll place it here for you now. “A nor’easter,also northeaster; is a type of macro-scale storm along the East Coast of the United States and Atlantic Canada, so named because the storm travels to the northeast from the south and the winds come from the northeast, especially in the coastal areas of the Northeastern United States and Atlantic Canada. More specifically, it describes a low pressure area whose center of rotation is just off the East Coast and whose leading winds in the left forward quadrant rotate onto land from the northeast. The precipitation pattern is similar to other extratropical storms. Nor’easters also can cause coastal flooding, coastal erosion, hurricane force winds, and heavy snow. Nor’easters can occur at any time of the year but are mostly known for their presence in the winter season. Nor’easters can be devastating and damaging, especially in the winter months, when most damage and deaths are cold related, as nor’easters are known for bringing extremely cold air down from the Arctic air mass. Nor’easters thrive on the converging air masses; that is, the polar cold air mass and the warmer ocean water of the Gulf Stream.” I’ll have another weekly weather quiz question for you starting next Monday. Please post your answer as a comment by clicking on “no 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.
