Here is my weekly weather quiz question for the last time. What is an“Adiabatic Lapse Rate?” Here is the correct answer. An Adiabatic Lapse Rate is the rate of decrease of temperature experienced by a parcel of air when it is lifted in the atmosphere under the restriction that it cannot exchange heat with its environment. For parcels that remain unsaturated during lifting, the (dry adiabatic) lapse rate is 9.8°C per kilometer. I’ll have a new weekly weather quiz question for yopu starting Monday. Please remember to post your answer at the bottom of this page. An email will not suffice. 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 High (Shaded “Arch” shape with blue arrows) to our Northwest is sending cold air down to us from Canada. Low pressure to the South combines to return the moisture to Oregon by late Friday. The days 1-3 graphic shows  surface low and frontal system that is moving Southward along the Pacific Coast and then inland well to our South by Wednesday giving us the short break from the precipitation chances. The graphic for days 3-7 shows the break from storms Thursday and most of Friday. Then more frontal systems that will be headed our way late Friday into Saturday and again Monday.  For mountain snow conditions at the local ski areas check out their websites or give them a call.
