COLD AIR SPILLS IN

Presently, there is a strong ridge just off the west coast off the USA. Just underneath though, a cut-off low pressure system continues to churn. This formation of a High over a Low is blocking pattern and deflects the Jetstream. In this case, much of the Pacific flow is going up and over the ridge, sending cold Canadian air into much of the northern plains. Some of this cold air will reach us!

By Wednesday and especially into Thursday, moisture, working in form the Southwest looks to overrun this cold air. The depth of the cold air will not be sufficient for snow, but it will be below freezing in places at the surface. So, some sleet, rain and freezing rain may be in the cards. We're watching this scenario unfold and will be timing things in the days to come.
