We dodged the worst of this Serial Derecho with the 100-112 mph gusts (some damage suggests up to 125 mph) in east-central & eastern Iowa & the 80-100 mph gusts across northern Illinois to far northern Indiana.
Here, highest measured gust was 73 mph & overall gusts tended to be in the near 50-73 mph range. It does appear there were gusts +75 mph Newton County & a possible brief tornado spin-up or two.
There are reports of wind damage in every county except White County as I have gone through every severe weather report from NWS to all of our spotters & viewers. Clinton County has the second least with one & that was a large tree limb down near Rossville.
Earlier fog & low cloud deck continues to break up & more & more of the area is seeing partly cloudy skies.
It is still humid, but not as bad as yesterday & temperatures are cooler at 75-81 (north to south) as of 1:52 p.m. Dew points are 63-72 over the area (north to south).
Surface cold front runs along I-70 in Indiana & is slowly sinking southward, so any isolated shower that can pop will be south of our area this afternoon-evening. Thus, I have removed the 20% POPs for the area.
Due to cold front pushing farther southward, I dropped highs from 83-90 projection to 80-86.
The weather looks pretty good for a few days as winds turn to the northeast then east & the humidity drops a bit.
Some patchy fog could occur Wednesday & Thursday morning with lows 57-64 & highs 79-86 (with partly cloudy skies).
This will occur as cold front stalls & stays south of our area.
However, it will move back northward as a warm front Friday, bathing us in very warm to hot, muggy air for this weekend.
With that airmass, multiple rounds of storms may occur on periphery of intense heat & humidity. However, a pretty strong cold front & upper trough will flatten & then push the hot upper ridge west, bringing us cooler weather. This sequence of events will bring risk of storms Friday night through Sunday & Monday. Multiple rounds of storms are possible. The better mid & upper flow will for widespread severe storms will reside northwest of our area, but we will still need to monitor. There is at least the risk of isolated severe storms at times.
It still looks like a streak of below normal temperatures is ahead for mid-August following this brief heat-up this weekend.
Monday, August 17-Thursday, August 20 of next week shows a tendency for below normal temperatures.
However, it still looks like late August to early September will turn hot & humid with overall streak of above normal temperatures. It also still appears that there will be two periods that tend to drive up the overal mean temperature with both periods seeing 90s. One or both of these may be classified as a heat wave (5 days or more at or above 90 degrees).
Note how a few "Ring of Fire" or "Ridge Riders" (storm complexes on periphery of hot upper ridge) try to make it in here at times.
However, overall, late August to early September is trending drier than normal with the heat. This could change if a tropical system can make it in here.
Trends are for the northwest Corn Belt & Northern Plains to have heavy rainfall & considerable severe weather & then tropical rainfall will be in the Southeast U.S.
There is a trend to bring temperatures a bit below normal in mid-September after this stretch of above normal temperature dominating (lows well down into the 40s).
