WAUSAU, Wis. (WSAW) - A lifting low pressure system arrives Thursday, pushing a warm front through the state. This will help bring high temperatures back into the 40s Thursday and Friday. However, the front is expected to trigger a widespread weather maker for much of the state. The type of precipitation will vary in different parts of the Badger State.

Most areas can expect to see rain and thunderstorms starting Thursday afternoon or evening tracking in from the southwest. Areas over the north will be cooler, seeing more of a wintry mix featuring snow and freezing rain, likely setting up somewhere along or north of HWY 64. Rain could be heavy at times over North Central Wisconsin Thursday evening, especially for those under thunderstorms. Thunderstorm are not expected to be severe for North-Central region.

Expect widespread preciptation to continue through much of Friday. Rainfall and thunderstorms from overnight could create some issues for the morning commute Friday for areas who tend to see issues during rainfall type of events. Current forecast models are starting to hint at a possible ice threat for the Friday morning commute. A band of freezing rain could develop along and north of the HWY 29 corridor throughout Friday morning, resulting in ice accumulations. If this forecast holds true, this could cause major travel impacts for Friday morning. Mixing of snow and freezing rain will still try to fall and accumulate over the far northern parts of the state during the morning and afternoon. Elsewhere, expected mostly widespread rainfall where temperatures allow.

Another chance for some thunderstorms during the afternoon or evening Friday over 3/4 of the state. We do not expect thunderstorms Friday to become severe over North Central Wisconsin, but areas over Southern Wisconsin have a chance for a few severe thunderstorm developments, during the afternoon or evening. Non-severe thunderstorms over North Central Wisconsin will still pose localized flooding threats from heavy rainfall.

Rainfall amounts over much of Central Wisconsin from Thursday through Friday evening will range from 1-2 inches in total. The heaviest rain likely tracking somewhere along and south of HWY 29. Make sure storm drains near your home are clear of debris to allow for rain to flow correctly.

Temperatures will cool down from Friday night through Saturday as a cold front slips in. Areas under widespread rainfall will see a switchover to widespread snowfall as the front passes through and ushers in colder air overnight. Snow continues through Saturday morning for the region, clearing out at some point during the day as the system tracks off to the east. Highs cooler, in the mid-30s.

Snow accumulations will be more of a wet type of snow. Accumulations higher over the Northern parts of the state due to cold air filtering in earlier allowing for snow accumulations to start at some point during Friday evening. Snow accumulations North of HWY 64 around 4-8 inches possible. Some ice accumulations will be underneath the snow accumulations. Areas south over Central Wisconsin, could see snow amounts ranging anyfrom from 1-4 inches. High confidence for those around the HWY 29 corridor to pick up a minimal of 2 inches of snow.

Likely drier for the second half of the weekend, Sunday. Partly sunny skies. Sunday or Monday could be when we hit our first 50-degree day of the season!
