It was a mild finish to 2011 and start to 2012 with spring-like temperatures in the 50s. However, changes will take place tonight as a cold front passes through the Delaware Valley.

Besides a few showers around, the big story will be what’s behind the front. Strong winds will begin to usher in an arctic air mass to the region on Monday. Highs will be back closer to average in the lower 40s.

The true arctic air will surge in Monday night with a few flurries possible in some spots. The wind will continue to howl through the day on Tuesday with highs only in the low 30s. Wind chill values will be well into the teens though the day.

Wednesday morning will be the coldest morning of the season with lows into the teens. The wind will diminish a bit for Wednesday but highs will be very cold in the low 30s again. The cold spell will be brief as the arctic air begins to life out for Thursday with highs back to near average of 40 degrees. It then looks like we will make another run at some 50 degree temperatures for the weekend.
