Here is my weekly weather quiz question for the last time. What is “AFOS?” Please remember to post your answer at the bottom of this page. An email will not suffice.

________________

The Jet Stream (Shaded area with blue arrows) continues sending warmer air in to replace the colder air at the surface. Another disturbance will return the chance of snow by late today.  The days 1-3 graphic shows the next surface low and frontal system heading inland Tuesday into Wednesday on a similar track as the previous storm. The graphic for days 3-7 shows no slowdown in frontal systems that will be headed our way in the near future. For mountain snow conditions at the local ski areas check out their websites or give them a call.
