Good Tuesday Evening! It is quite cold and even snowy at times for many of you tonight. We will have a few more chances of wintry precipitation yet this week as arctic air is locked in. However, attention is beginning to turn to this upcoming weekend. A powerful storm system will bring snow across the Plains, Severe Threats to the south, and more rain for our area.
In addition to the rain, we expect milder air to move in Saturday into Sunday, which will keep the snow away from the area. However, we will be dealing with a deepening low pressure with a tight gradient. Tight pressure gradients are a sign of strong winds and a dynamic system. For our area, this means another windy weekend is looking possible.
Above is a look at the forecast wind speeds at 850 Millibars (5,000 Feet) overnight Saturday into Sunday Morning off of the afternoon model run of the GFS. These wind speeds are above the surface, but still in the lower levels of the atmosphere. Remember a couple of weekends ago with strong to damaging winds? *IF* these models were to verify, we could be looking at quite an interesting end to the weekend. Highs will get into the 50’s (and possibly the 60’s), which will help to fuel the tight pressure gradient.
Right now, we are going to be conservative with the wind gusts. However, wind gusts of 45 to 55 MPH are certainly possible across the Great Lakes. Here is how that breaks down for our local area. Again, we have several days to watch this. However, models have been rather consistent on this potential. Stay tuned for updates!
