Below is an image I put together showing the weather around the Great Lakes from this evening. The arrows indicate the direction and speed of wind - the shortest arrows represent 5mph winds while the longest arrows represent 25mph winds. The snowflakes represent light snow and the clouds represent overcast skies. By looking at the wind pattern, you can kind of make out where the low pressure system that just passed through this weekend is located.
According to noaa.gov, the current barometric reading is 1016.7 mb. Below is a diagram of the barometric pressure throughout the day from UW - Eau Claire's weather page. The trend shown can be associated with the low pressure system moving out and a high pressure system coming in. Based off of that, we should see some sunny skies for tomorrow, perhaps in the afternoon.
The image below is from intellicast.com. It shows the predicted jetstream for tomorrow. What is very noticeable about the jetstream is a prominent trough in the central U.S. and the southern Rockies. Associated with the trough are calmer winds and cooler temperatures. Moving west or east away from the trough, temperatures and wind speeds increase. You will also notice a trough in the northwestern part of the map and a broad ridge in the southwest.
Below is an image from noaa.gov of watervapor. In this image you will notice on the east coast a distinct line between where there is little watervapor and where there is more concentrated watervapor. This is associated with the low pressure system, or nor'easter, that just dumped around 30 inches of snow in some areas of New York and Massachusetts.
And judging by the diagram from below from accuweather.com, it is predicted another low pressure system will produce more storms for the east coast by this weekend, as part of the end of February's string of storms. Because this same low pressure system will be passing through Eau Claire, we should expect to see some precipitation sometime between wednesday night and friday morning.
