Warm air advection can be identified in the Great Lakes region with a thermal gradient of 0 to approximately 9 degrees Celsius. Winds in the Midwest appear to be out of the southwest ranging from 45 knots in the southern United States to nearly 20 knots in northern Indiana.

The strong southerly winds will bring warmer temperatures throughout much of the Lafayette area. High temperatures during the weekend should reach the low 60s. The weekend will be dominated by nicer weather, so it would be nice to enjoy outdoor activities this weekend.

A developing cold front is also approaching in to Monday next week. A strong vorticity max will allow for positive vorticity advection throughout much of the regions in front of the cold front. Precipitation will be expected Monday into Tuesday.
