Bombing Out

A highly unusual weather scenario is developing for this time of year. A low pressure system is currently bombing out (i.e. strengthening really really fast) in the vicinity of Indiana. This system is expected to retrograde northwestward and stall out over southern Lake Michigan by tomorrow. The result should be some decidedly un-May-like weather through the weekend. Expect the following conditions:

1) Winds: A Wind Advisory is in effect for most of Wisconsin for Thursday, with sustained winds of 25 to 35 miles per hour expected, and gusts of 40 to 50 miles per hour.

2) Temperatures: The mercury will struggle to climb out of the 40s tomorrow and Friday, and below normal temperatures are expected to persist for the next several days, likely through at least the beginning of next week.

3) Precipitation: Rain is likely tomorrow, and there will be chances of rain every day through the weekend. The heaviest rain should fall across eastern Wisconsin and Michigan. There is an outside chance that the rain could mix with snow sometime tomorrow, if enough cold air mixes in. The best snow chances are across far northern Wisconsin and the Upper Peninsula, where a Winter Storm Watch is in effect. In those areas, wet, heavy snow could combine with the strong winds to create some big problems, most notably from snow-laden tree branches falling on powerlines.

Just when we thought the weather couldn't get any weirder...
