Spring is in the air. Not only are west and south suburban high temperatures to surge to the highest levels of any weekend since September, but humidities are to rise as well. Increased humidity level lends air a truly springlike feel by reducing heat-removing evaporation of moisture from our skin. The year’s first 60° dewpoint (a measure of moisture)—comparable to Gulf Coast levels late Friday—is predicted here late Sunday—the highest dewpoint here since Oct. 29.
Warming was in full swing in the Plains and Upper Midwest Friday. International Falls, Minn., recorded its highest temp (67°) since Oct. 11 while new high records were established for the date at Williston (86°) and Dickinson (80°)—both in North Dakota. These readings are more than 30 degrees above normal.
The Chicago area received 100 percent of its possible sun Friday—only the fifth day in 2005 to do so.
