ROCKFORD (WREX) – The weekend is almost here and with it, sunshine is plentiful and temperatures will be very warm.
High pressure has moved in this morning and is anchored just to the west of the Stateline. Under the influence of sinking air, plenty of sunshine is to be expected today. High temperatures will likely land a few degrees higher than on Thursday, where Rockford recorded a high of 85°. Upper 80’s will likely be plentiful and cannot even rule out a few locations climbing to 90°.
Dew points will slowly begin to inch upwards through the day. They will slowly increase into the mid 60’s or so by the overnight hours. Once dew points climb above 60°, you slowly begin to notice the humidity a bit more. With that being said, today will still be a pretty comfortable day. Heat index values will likely only be in the upper 80’s to low 90’s. While that’s still quite toasty, it’s a far cry from where heat indices could be later this weekend and especially next week.
If you plan on heading out to City Market in Rockford, or if you plan on heading to the Stephenson County Fair, you’ll have gorgeous weather awaiting you tonight. As high pressure slides to our east, winds will become more southwesterly, indicating an abrupt end to the relatively comfortable humidity we’ve been able to enjoy over the last 48 hours.
Steamy weather returns tomorrow. Temperatures tomorrow afternoon will likely top out near 90 and some spots may even get into the low 90’s. Let’s discuss heat index values! Dew points are forecast to be in the mid 70’s at times. If that indeed does verify, we could see heat index values hit or exceed 100°.
There is a system that could bring scattered thunderstorm chances during the afternoon hours. At this time, it looks like thunderstorm chances look to peak between 12 and 5 p.m. If you have outdoor plans tomorrow, just be ready to head indoors for a bit until storms come to an end.
Sunday looks to be a virtual repeat of Saturday, but storm chances look a bit more isolated. The pattern of afternoon storm chances remain in place through much of next week, as heat and humidity continue to build.
