ROCKFORD (WREX) — Temperatures continue to climb through the week, which indicates a very toasty weekend to come. Alongside building heat and humidity, storm chances return to the Stateline.
Thursday afternoon features above average highs, with most spots topping out in the middle to upper 80s. You likely notice a touch more humidity in the air and that's thanks to an increase in dew points, with many areas sitting in the 60s. As a reminder, any time dew points climb into the 60s, you start to notice humidity.
The added moisture to the atmosphere might allow for a few more clouds, especially during the afternoon hours. Wednesday featured crystal clear blue skies and little in terms of cloud cover. Thursday shifts to a mostly sunny to partly sunny sky.
Southeasterly breezes continue to pull in slightly higher dew point temperatures, especially by week's end. Through Thursday, winds around an area of high pressure to the east could gust to around 15 miles per hour.
One more dry day:
Friday features continued dry weather, but a few more clouds stream in for the afternoon. After a seasonably cool start to the day, with lows in the upper 50s and lower 60s, highs to wind down the work week climb into the upper 80s. In terms of heat indices Thursday and Friday, they'll remain generally below 90°.
A partly cloudy sky is the rule of thumb for the end of the work week ahead of a somewhat wet start to the weekend.
Saturday rain chances:
A cold front moves through the Stateline during the latter half of the day Saturday. This brings a return to rain and thunderstorm chances, but the day doesn't look to be a washout. Forecast guidance depicts a scattering of showers and thunderstorms along the cold front during the afternoon and evening.
I am not recommending cancelling outdoor plans Saturday, but take precaution to head indoors if you hear thunder roar.
Drying out and cooling down:
The tail end of the weekend features a drop in rain chances and in humidity. Highs Sunday top out in the lower 80s with abundant sunshine. Believe it or not, even cooler weather is ahead for next week. Highs through midweek drop into the middle to upper 70s with continued dry weather.
