As we arrive to summer's midpoint, a quick look at how it has shaped up so far. In summary, warm and most notably humid. The humid air has been assisted by an unfavorable weather pattern for cold fronts, wet ground, and evapotranspiration from mature crops in agricultural areas. pic.twitter.com/3JeSpWjeGg— NWS Chicago (@NWSChicago) July 18, 2018
Little cooler Wednesday. Then an unsettled pattern sets up for the end of the work week and the weekend. pic.twitter.com/HxeO5CjptP— NWS Chicago (@NWSChicago) July 17, 2018
High waves through this evening will create dangerous swimming conditions at Northwest Indiana beaches. pic.twitter.com/QsIxFX7nuX— NWS Chicago (@NWSChicago) July 17, 2018
After what seems like weeks of humid conditions, last night's cold front is helping usher in much more comfortable humidity levels thru Thur pic.twitter.com/7VQSa7zEZR— NWS Chicago (@NWSChicago) July 17, 2018
Dense fog is likely early this morning south of Valparaiso to Kankakee line. Fog will quickly dissipate early this morning. pic.twitter.com/glZuOCQpGi— NWS Chicago (@NWSChicago) July 17, 2018
