Dry air invaded Chicago Sunday, dropping dew points into the 20s and producing a 21 percent relative humidity level at Midway Airport—the lowest value recorded here since a 17 percent reading back on Feb. 26, 2006. The dry conditions will not last long, however, as warm and considerably more humid air is expected to surge into the area on Monday, setting the stage for several periods of showers and thunderstorms beginning Monday night and continuing into Wednesday.
Severe weather continued to rake the Plains Sunday, though activity was greatly reduced from Saturday’s battering that produced reports of 93 twisters.
It is only May, but hurricane forecasters are focusing their attention on a low pressure system off the Carolinas. Currently producing winds to nearly 50 m.p.h., the non-tropical system is expected to strengthen as it loops westward toward the Southeast coast and possibly gain some tropical characteristics.
