Staying oppressively hot and humid, heat advisory issued for some

The summer heat returned in a big way on Father's Day, leaving the Rockford Airport with it's warmest day of the year thus far. 

Officially, the mercury peaked at 94°. This mark may very well be tied or eclipse later today as this oppressively hot and humid weather pattern aims to carry on into the new work week.   

 

Little to no relief came in overnight as cloud cover held lows in the low to mid 70s. This will provide a nice base for temperatures to quickly climb under a mostly sunny to partly cloudy sky, landing highs in the low to mid 90s this afternoon.  

Of course with dew point values in the upper 60s and low 70s, heat indices will once again approach the century mark at times. Some may eclipse the 100° mark, hence the Heat Advisory that has been issued for Jo-Daviess, Stephenson, Carroll, and Whiteside County. Forcing won't be as strong, meaning the likelihood for widespread storms is low. However, a very summer-like pattern such as what we're in will provide the low chance for one or two showers or storms. Skies remain partly cloudy overnight, with temperatures falling into the mid 70s. 

Rain chances stay isolated for Tuesday. Temperatures take a step back to the low 90s, though heat indices will still end up in the upper 90s. 

Strong ridging to the east will continue to keep our weather pattern hot and humid conditions into the end of the work week. Surface flow will remain out of the southwest, allowing highs to top out in the low 90s Wednesday through Friday. Again, we'll remain under Heat Advisory criteria as upper 60 dews will keep heat indices under the century mark. 

With that being said, continue to take caution from the oppressive heat and humidity. Drinking plenty of fluids, taking frequent breaks in the shade and A/C, and wearing light clothing are all ways to lower your chances of getting a heat-related illness. 

A cold front will help increase rain chances during the Wednesday-Thursday time frame. Another heightened chance for storms arrives Saturday into Sunday as the east coast ridge flattens out, allowing a trough/low pressure system to glide into the Great Lakes.
