Good Wednesday morning!

Weather Synopsis
Aren't you glad all that rain that fell yesterday wasn't snow? There were some reports of freezing rain early yesterday morning across parts of central Wisconsin, but southern Wisconsin and the Fox Valley seemed to avoid that nasty scenario. However, we may still have our chance to be the lucky recipient of some springtime snow as a series of strong low pressure systems keeps churning through the United States, bringing both rain and snow our way. Besides some light snow showers or flurries today, another round of rain and/or snow moves through tomorrow night and again Saturday night and Sunday, the latter of which could actually accumulate to a few inches of new snow! What, you think I'm kidding? Check around, pal! Today may be the first day of April, but it sure isn't going to feel like it outside for a while.

Today’s Forecast Grade: I

Wisconsin Forecast:
Today: Cloudy and windy with scattered light rain or snow showers, mostly this morning. More of a nuisance than anything else, really. Maybe a small break in the clouds this afternoon before more clouds roll in late. High of 42 central, mid- 40s south. Chance of measurable snow just 25% central, 15% south.

Raw Model Data: (combined numerical output range from three different NOAA weather models)
Appleton: Highs 25-85. Chance of precip 0-100%.
Madison: Highs 14-97. Chance of precip 0-100%.
Waukesha: Highs 21-79. Chance of precip 0-100%.
Steve's New Basement: Highs 66-67. Chance of precip 0%-0%.

Tonight: Partly sunny. Highs upper 30s central, near 40 south.

Tomorrow: Cloudy and becoming windy again with showers and isolated thunderstorms developing late in the day south. Highs low to mid- 40s central, mid- to upper 40s south. Rain turning to light snow tomorrow evening and overnight as it spreads across the rest of eastern Wisconsin. Chance of rain during the day 50% south, 25% central. Chance of precip tomorrow night 70%.

Friday: Partly sunny, highs 44-49.

This Weekend:
Saturday: See also, Friday.

Saturday Night: Cloudy and windy with rain or snow showers likely south, gradually spreading into central Wisconsin overnight. Lows near 30. Chance of precip 60%.

Sunday: Cloudy and windy with rain and snow likely. I would not be surprised to see another couple inches of snow develop from this thing depending on the final track of the system and how much of it falls as snow where you live. Highs 41-46. Chance of cursing mother nature 60%.

Next Week’s Outlook: All of you who are expecting warm spring temperatures to arrive will just have to wait a little while longer. Maybe some light rain or snow Wednesday night as a large storm system just grazes us from the south, otherwise dry with below-normal temperatures in the low to mid- 40s for highs. At least it will be in the upper 60s to near 70 inside your house as you watch Opening Day baseball from your living room.

Independence Day Outlook: Mostly sunny in the morning with increasing clouds late in the day. Scattered showers and thunderstorms developing in the evening and continuing overnight, some of which may be severe south. High of 83. Low of 64. South winds 10 to 20 mph turning northwest 5 to 15 mph overnight. Barometric pressure 29.87" in the morning, dropping to 29.52" by late in the afternoon.

Other City Forecasts:

Today and Tomorrow in Minneapolis/St. Paul, Minnesota: Breezy with snow this morning, mixing with rain this afternoon. Partly cloudy tomorrow. Highs near 40, don'cha know? Maybe that's why your university is named after gophers - the nasty weather just makes you want to live in a hole in the ground!

Today and Tomorrow in Anna, Illinois: Sunshine today, no sunshine tomorrow. Sorry. Storms likely tomorrow as well. Highs mid- 60s.

Today and Tomorrow in League City and Pearland, Texas: Partly cloudy and breezy y'all. Highs low to mid- 70s.

Today and Tomorrow in Hilton Head Island, South Carolina: Breezy with showers and thunderstorms likely. Highs near 70. Flooding of biblical proportions possible ... REPENT!!!
Through 8 am...rain will continue to affect southeast South Carolina. Majority of the rain will remain light with rain totals ranging from a trace to a few hundredths of an inch in a hours time. Majority of the rain will remain along the coastal counties and across portions of Allendale and Hampton counties during this time period.

Today and Tomorrow in Las Vegas, Nevada: Golden chips a'plenty falling from the sky between 5 p.m. and 7 p.m., redeemable at any of the Forum Shops at Caesar's. Bring your umbrella along but hold it upside-down to really rake in the cash! Highs around $2,500!

Today and Tomorrow in Davenport, Florida: Scattered thundershowers, highs mid- to upper 80s. You can still golf in that but I would recommend plastic clubs.

Today and Tomorrow in Albuquerque, New Mexico: Who cares?

This Day in WisconsinWeatherUpdate.com History (2003):

Spring Weather Statement:
Winter Storm Watch For Tonight and Tomorrow...
Periods of rain or freezing rain can be expected through the afternoon hours... thus expect a significant coating of ice on untreated surfaces. Snow is then expected to redevelop later this afternoon and continue through tonight and tomorrow. Total accumulations of 12 to 18 inches are expected by tomorrow evening. In addition... northerly winds are expected to increase to 15 to 30 mph later tonight... causing significant blowing and drifting snow. The combination of snow... freezing rain and sleet will make roads slippery. Use extreme caution if you are traveling and allow plenty of time to reach your destinations.

Today: A strong area of low pressure is building in from the central Plains, which will combine with the low pressure system that gave us a mix of light rain and snow yesterday. This combination of systems will push a lot of new moisture and instability to our area. Ahead of the cold front associated with this new low, precipitation will begin to fall as rain, but will quickly turn over to freezing rain and eventually snow by the later afternoon hours as the front passes. Snow may be heavy at times this evening, and combined with strong winds and fog will likely help to create near-blizzard conditions across the area. Because this system is moving so slowly, a Winter Storm Watch has been issued by the National Weather Service for most of the state, from a line south of Rhinelander stretching to about Rockford, Illinois, and from Prairie du Chien through parts of western Michigan. Highs mid- 40s early, then dropping during the afternoon hours as the cold front passes.

Tonight: Snow continuing, mixed with plenty of wind and fog. Yuck! Lows upper 20s.

Tomorrow: Snow eventually ending by evening. 6-12" of new snow is expected across southern Wisconsin, with areas near the Fox Valley getting between 12-18" by the time tomorrow night rolls around! Highs only lower 30s.

Extended: Talk about a thaw! A nice surge of warm air will move in by Thursday due to a good southwest flow behind an area of high pressure to our west. This will push high temps in the upper 50s Thursday, mid- to upper 60s on Friday, low to mid- 70s Saturday, and perhaps lower 80s by Sunday! The record high in Madison for this upcoming Sunday is 85 degrees, set back in 1991, so this may challenge that record! After that, another stretch of cold weather will move in for next week, pushing temps back into the 30s and 40s. Gotta love spring in Wisconsin!
