Good Monday morning!
We had another seasonable weekend with some light snow developing on Saturday, clouds during the day yesterday, and some light snow developing again last night. High temperatures were just above 30, which is right around our average for the last week of February.
Well this was a wild weekend of weather forecasts if you live in southern Wisconsin. A low pressure system that couldn't quite make up its mind on how far north it wanted to bring its snow changed last night and today's forecast in southern Wisconsin from cloudy, to a Winter Storm Watch and 6-10" of snow, to a Winter Weather Advisory with 2-6" of snow, and overnight the advisory was cancelled early in south-central Wisconsin and will be ending shortly in southeastern Wisconsin with just 2-4" of snow expected by around lunchtime. East-central Wisconsin was never under any watch or advisory, but an inch or two of new snow is possible this morning as the snow gradually pushes east over Lake Michigan.
Another little disturbance could give us more light snow tomorrow night and into Wednesday, then an upcoming upper-air jet stream trough brings in colder air from Canada, so expect high temperatures in the 20s instead of the 30s for the second half of the work week.

Snow from a storm system tracking toward the lower Great Lakes will continue to affect east-central Wisconsin for a time this morning. The primary snow band will affect areas south and east of a line from Wautoma...to Clintonville...to Oconto...to just north of Sturgeon Bay. Areas farther west should receive just flurries. Areas within the primary snow band could see visibilities briefly fall to below 1 mile at times. Most locations affected by the snow band will receive an inch or two of snow...though totals out near the western edge of the band will be a bit lower. Although temperatures were within a few degrees of freezing...the snow will fall hard enough to accumulate on untreated roadways. Morning commuters should be alert for the possibility of snow on roadways...and use extra caution. The snow should taper to flurries by mid-morning.
... Winter Weather Advisory remains in effect until 10 am CST this morning...
* Timing... accumulating snow will gradually diminish from the west later this morning. However some periods of light snow and flurries are still expected into the afternoon.
* Snow accumulations... total accumulations of 2 to 4 inches are expected.
* Winds... northeast winds will increase to 15 to 20 mph.
* Impacts... snow will lead to some slippery travel conditions...especially for the morning commute on untreated roads.
A Winter Weather Advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities... and use caution while driving.

...Lack of mild weather keeps snow cover on ground...
The Green Bay area has seen a longer than usual period of cool weather
and solid snow cover this winter (defined here as December through
So far during the winter of 2009-10 in Green Bay, only two days
experienced temperatures of 40 degrees or greater--both of those were at
the very beginning of December. In fact, temperatures have remained
below 40 in Green Bay since December 3. The current streak of 77
consecutive days without a high temperature of 40 or greater in Green
Bay is the 15th longest in 114 years of data. The longest such streak
is 112 days during the winter of 1903-04. More recently, the winter of
2000-01 had a run of 91 consecutive days under 40.
If the temperature stays in the 30s today and through the end of the
week, the current streak will likely last through the end of the month
and into early March as colder air is on the horizon. That would vault
the current run of consecutive days below 40 degrees into the top 10.
The cool temperatures have kept the snow cover in check across the area,
too. Through Thursday morning, Green Bay has recorded a snow depth of
at least 1 inch since December 9 (readings are taken at 6 am daily; data
available since 1948) -- 71 days in a row with snow cover. That is
nowhere near the record of 124 days in a row set during the winter of
1985-86. Just last year, Green Bay recorded 106 consecutive days with 1
inch or more on the ground -- the sixth longest streak. If the snow
cover can hang around during the next few days, the current streak would
jump into the top 20.
