Freezing drizzle and light snow will develop late tonight and into tomorrow morning. As warmer air pumps into Southeast Wisconsin tomorrow, all precipitation will transition into rain by the afternoon hours. A low pressure system will approach Wisconsin on Monday, bringing with it slightly above average temperatures and more rain through Wednesday. This rain will eventually transition over to snow by Wednesday evening. As the low moves off to the northeast on Christmas, cooler air will flow back into Wisconsin, bringing our high temperatures closer to normal. There is still considerable variability in the track of this low pressure system, and any significant changes in where the low will move may dramatically change the amount and type of precipitation we get.
