Gradual warming on tap, heavy rain possible Saturday
Residents looking for any signs of spring in south-central Wisconsin should take some solace the rest of the week, as temperatures gradually warm up to 40 by Saturday.
The down side to the warmer weather is the chance for heavy rain on Saturday, and mixed precipitation both before and after the rain.
The National Weather Service said Madison could see up to an inch of rain Saturday and Saturday night, which could lead to localized flooding both in the countryside and in low-lying urban areas.
That’s if the strong low pressure system moving through the region stays on the forecast track.
“If the low goes farther south, the precipitation may end up as more of a wintry mix across more of the area Saturday and Sunday,” the Weather Service said.
Before we have to choose between umbrellas and snow shovels, we should have a quiet stretch of weather in Madison, with temperatures moving up the thermometer.
A high of 23 is forecast for Wednesday, with a slight chance for flurries in the afternoon and evening, then it should be partly sunny and 23 on Thursday.
The high should top the freezing mark at 34 on Friday, with a small chance for snow early in the morning.
Saturday might be a good day to stay inside.
The Weather Service said the day could start out with snow before 9 a.m, then freezing rain between 9 a.m. and 11 a.m., then rain after that, with patchy fog after 4 p.m., the high reaching 40.
On Saturday night, rain is expected before midnight, then rain and snow from midnight to 3 a.m., and snow after 3 a.m into Sunday morning.
Rain could mix with snow after 11 a.m., before gradually ending. Sunday’s high is forecast to reach 36.
The mixed precipitation will be accompanied by strong winds, gusting up to 30 mph on Saturday and up to 45 mph on Sunday.
The work and school week should get a nice start, with partly sunny skies and 35 on Monday and mostly sunny skies and 37 on Tuesday.
