Keeping it Cold

My predictions from yesterday were fairly accurate.  The temperature did decrease, and it was around zero for most of the day (although it felt much colder due to the wind chill).  The wind picked up to a strength of light to moderate, and it also switched direction and was coming from the SW this afternoon.  Currently, there is a WSW wind at ten miles per hour.

The sky was also clear and blue for most of the day.  This is due to the high-pressure system to our WSW.  As I learned in class earlier today, pressure systems coming from the Northwest are commonly directed by the Rocky Mountains into the Great Plains.  Over the past couple of days, a high-pressure system consisting of a continental polar air mass has been shifted in this way (see map below).

I'm predicting minimal changes in the weather for tomorrow.  The continental polar air mass will keep the temperature in the colder range, and the high-pressure system will more than likely prevent any precipitation from occurring.  Thus, I expect a sunny, blue sky again tomorrow.
