Good morning! Here is your latest forecast update:
Past 24 hour rainfall accumulations:
Simulated radar from 7 PM Monday through 10 AM Tuesday. It looks like the onset of this event will fall initially as rain before we transition into snow across the Milwaukee area. As things stand now, SE Wisconsin looks to stay too warm for much of snowfall accumulations with mostly rain expected. Milwaukee looks to be centered more under the axis of higher liquid content, allowing for snow ratios around 5:1.
Here is a look at modeled temperatures from 7 PM Monday through 10 AM Tuesday. Initially temperatures will be warm enough for rain on the onset of this event. Temperatures will drop from NW to SE as we progress through the night with the Milwaukee area seeing near 32 as we to around 5 AM. Because temperatures will be hovering around the 32 mark, some initial melting will be possible but we could see accumulations on roads where snowfall rates are the highest. Grassy accumulations can be expected.
Temperatures will warm up on Tuesday with mostly sunny conditions. Here is a look at high temperatures on Tuesday. Any snow that accumulates will likely melt during this the afternoon hours of Tuesday.
Temperatures look to fall back close to 32, especially the farther north you go. Milwaukee looks to be on the border of slightly warmer temperatures but the risk is there that 32 to could be met. SE Wisconsin as is stands now look to remain on the warmer side with temperatures above 32. Will need to monitor this closely. Here is a look at modeled low temperatures Tuesday night/ Wednesday morning.
Here is a look at sustained winds from 7 PM Monday through 10 AM Tuesday. Some breezier conditions will be possible as the snow is falling but winds will calm down as the system departs. The weaker winds will allow the water at the surface to stick around longer, increasing refreeze risk Tuesday night/ Wednesday morning. Winds look to generally be out of the north- northwest during this time.
Here is our preferred model snowfall amounts for this event.
