Thank you for stopping by the Weather Watch 12 blog! If you missed the past two entries that Mark did about ‘ice balls’ and ‘ice volcanoes’ check them out right after this entry. Very interesting Great Lakes phenomena!
Cold weather has been the story the past 2 days, and it will continue to dominate the weather headlines for another 36 hours or so. Below is a surface map at 1pm Wednesday. Notice that temperatures are in the single digits to teens in many locations. The arctic air covers most of the Plains and Midwest!
With daytime highs struggling to reach 10 degrees in many areas, temps don’t have far to fall to produce a very cold night. This means that stepping out the door early Thursday temperatures of -5 to -10 will greet many. I think -5 or so is likely even here in the city!
The frigid start on Thursday will slowly warm to about 5 to 10 degrees during the afternoon.
If we stay in the single digits for daytime highs it would be the second time this season.
The good news about cold snaps heading into the middle part of February, they usually don’t last too long. The combination of a higher sun angle and longer days are a couple of signs that we are heading toward Spring.
By next week temperatures will easily warm into the 30s, if not the 40s across southeastern Wisconsin. Below is a forecast temperature map from the 12Z GFS for next Wednesday, February 17. Notice the 60s over parts of Missouri!
A couple of limiting factors will be in place that may keep our temperatures somewhat in check. The first is a deep snowpack, this will automatically keep temperatures cooler than what they potentially could be. Also, when a deep snowpack begins to melt, low clouds and fog can form and keep temperatures from warming.
Even if low clouds and fog form, I think temperatures should warm into the 30s, and if sunshine breaks through 40s are possible! If there was no snow, like in late December, we would be enjoying 50s!
Watch WISN 12 News for the latest as the cold ends and we transition into a milder part of the pattern.
Have a great day!
