29. Beautiful and cold yesterday, calm and warmer today, two snow systems over the next few days.
My picture (to the right) is from yesterday just before sunset. I took this from the lower part of my driveway looking NNE over a series of fields towards a range of forested hills. The sun was setting behind me but was still striking the top of the ridge.
Today was cloudy except a little clearing late in the afternoon as a shortwave was skirting along the US/Canadian border.
Snow chance number one.
A low pressure is currently coming out of the Northern Rockies and will be moving across the region Saturday. Ahead of the system some light snow is expected to fall. At this time the best chance seems to be across the border into Minnesota on Friday, but that snow could move east into Wisconsin by Saturday.
The map (to the left) is from The Weather Channel (TWC) and shows the forecast weather on Friday (top) and Saturday (bottom).
Accumulations will probably be light -- two inches or less with some places only receiving a dusting.
Behind the snow will be a cold front that will knock back our temperatures a few degrees. Friday's high temperature is expected to be in the mid 20s across the region, mid teens Friday night, mid to upper 20s on Saturday, and between 5 and 10 degrees on Saturday night.
Snow chance number two. Computer models continue to show a storm system on Monday. The map (to the right) is from the National Center for Environmental Prediction (NCEP) and shows the GFS at 96 hours from now, about 18:00 on Monday (4th).
The low pressure doesn't look especially strong, but the model does show precipitation over northern Wisconsin for about 24 hours. Also, the rain/snow line stays across southern Wisconsin, leaving the north completely under snow. Amounts over 24 hours could add up to several inches.
Having said that, the exact path of the low pressure is not definite yet, the computer models have not nailed it down.
