Rockford hit 94 degrees yesterday afternoon and peak heat indices in the Rockford area hit 101 degrees around 3PM yesterday. This marked the 9th time this year Rockford has hit 90. The 94 degree high ties the highest temperature so far this year back on July 18th and was just three degrees shy of the record of 97. This is also the first time since July 18th and 19th that Rockford has seen back-to-back 90 degree or higher temperatures. However, Rockford will not make it three as low clouds and northeast winds behind the cold front, which came through this morning, will keep temperatures throughout much of the day near 80 or in the lower 80s in places that get more sun. Behind the front, humidity has not dropped off at all; in fact as of the lunch hour in Rockford, dew points were still in the lower 70s making the air feel very muggy and tropical.
Tuesday night and Wednesday morning much needed rains stayed well to the north and east of the area on the periphery of the ring of fire pattern. With amble low level moisture in the region, patchy fog will develop late tonight and during the overnight hours into tomorrow morning.
The front that came through this morning will stall out and will come back as a warm front later this week. Uncertainty exists exactly where this will set-up for late this week and this weekend. Temperatures tomorrow should be near 90 and with the high humidity, heat indices will make it feel well into the 90s. Friday, Saturday and Sunday also look to be very warm and very humid.
With the front nearby, on the edge of the dome of high pressure off to our south, the northwest flow will set-up over us and give us periodic chances of showers and storms starting Thursday night and lasting through Sunday. Sunday a cold front will push through the region and knock temperatures and humidity. Our best chance of storms look to be Friday and Sunday, and some could be severe. Highs for Labor Day will be near the seasonal norms in the upper 70s under clear skies.
