Late Week System Brings Rain, Possibly Snow, for the First Weekend of 2020

The end of 2019 and beginning of 2020 will be quiet, but cold. Skies are beginning to clear from north to south Tuesday evening, eventually leaving us with a mostly clear sky to kick off the New Year. Temperatures will fall into the upper teens and low 20s.

Wednesday and much of Thursday will be dry and warmer. Southwest winds will increase during the afternoon Wednesday, gusting at times to 25 mph. This will bring temperatures up into
the upper 30s for the afternoon, and then into the 40s for Thursday. Cloud cover will increase during the day Thursday with a little drizzle during the afternoon. Rain showers become likely Thursday night into Friday afternoon as low pressure lifts up from the southwest. Depending on the overall track of the low, snow could be possible Friday night into Saturday. And depending on which model you look at, perhaps a decent amount. However, inconsistency is about the only thing forecast models have in common during that time period.

The track of the low will all depend on how low pressure develops within the jet stream. A more defined low will mean a stronger storm system and possibly a better chance for snow. A less defined low will mean a quicker moving storm system and less of a chance for snow. Either way, it is a time period to keep an eye on. Another quick moving low will zip across the Upper Midwest Sunday with possibly an even larger storm system heading into early next week.
