Here is my weekly weather quiz question for the last time. What is a “Panhandle Hook?” Here is the correct answer. A Panhandle Hook: Low pressure systems that originate in the panhandle region of Texas and Oklahoma which initially move east and then “hook” or recurve more northeast toward the upper Midwest or Great Lakes region. In winter, these systems usually deposit heavy snows north of their surface track. Thunderstorms may be found south of the track. 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.

An upper level low (Shaded “U” shape with blue arrows) returned and has pushed a frontal system down from the northwest bringing even more rain with mountain snow levels falling. The warm front moved in. The cold front follows between tonight and Sunday                                                                                                                                                                                                                                                         bringing the colder air and falling snow levels. We could see some pretty heavy rainfall in the valleys with snow in the mountains. A frontal system will slide down late next week.
