Here is my new weekly weather quiz question. What is “Apparent Temperature?” Please remember to post your answer at the bottom of this page. The first person to post the correct answer 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) has taken control of our weather sending a lot of moisture into the Pacific Northwest. The graphic for days 1-3 shows the frontal system moving through Oregon. The warm front moved through and the cold front is following behind it. The graphic for days 3-7 shows a series of frontal systems that will keep our weather active through next Thursday. For mountain snow conditions at the local ski areas check out their websites or give them a call.

*Note: Don’t forget to Spring ahead and turn your clock ahead at bedtime Saturday night (officially 2 am Sunday). Also, check the batteries in your smoke alarm, CO2 alarm, and Radon detector if you have them. Replace batteries as needed.
