Chilly start to weekend, but warm up coming: Skilling
Southwest winds on Friday brought the area its mildest air since February 20th. Temperatures reached the upper 40s across most of the area.
Following a cold frontal passage late Friday evening, winds turned north, putting the area’s warm-up on a temporary hiatus. Satellite imagery confirmed that over 90 percent of lake Michigan remains covered by ice. As northeast winds increase on Saturday, air flow off the ice pack will limit daytime readings to the low and mid 30s. Sunshine, and lighter winds on Sunday are expected to allow temps to moderate to seasonable levels.
Much stronger southwest winds are forecast to sweep across the area on Monday, negating any influence of lake Michigan. The area can expect its warmest air in more than three months as readings soar to the mid and upper 50s.
