MADISON (WKOW) - Our overperforming snow system has exited southern Wisconsin and a quieter, colder weather pattern is moving in.
Snow totals ranged from around 2-5" across southern Wisconsin. This was above forecast totals, especially closer to the Illinois border.
Snow switched over to rainfall farther south too late in the day. The area of low pressure that moved through the Upper Midwest stayed about 30 miles farther south than forecast.
This slight change in the forecast track kept our area on the "cold side" of the system, keeping the bulk of precipitation as snow.
High pressure moves in from the Northern Plains with increasing sunshine. Temps get to around 30°, but with a breeze out of the NW at 10-15 mph, wind chills will stay in the 20s.
Conditions turn much colder tonight with temps in the low single digits and wind chills sub-zero.
Wednesday highs only top off in the mid teens.
The Arctic-based high pressure system will be overhead by Thursday morning allowing temps to plummet below-zero with wind chills around -10° to -20°.
The cold is short-lived with temps getting to the freezing mark by Friday afternoon with upper 30s and low 40s this weekend with a good amount of sunshine.
