It was another sunny day in the Stateline with high temperatures again reaching the mid-60s for most. Cloud cover has been on the rise though ahead of our next weather system. This is already producing some scattered thunderstorms in Eastern Iowa. Gradually, the cells will move closer to the Stateline, possibly reaching the Mississippi River as early as 6/7PM.
That is when some of the isolated storms may begin, reaching peak intensity near 12/1AM. Temperatures will not fall far overnight, as rain keeps moisture high, keeping overnight lows in the upper 40s.
Futurecast shows rainfall starting as soon as 9PM for areas West of I-39, peaking around 12/1AM with embedded thunderstorms most likely to track near and along I-88. This will place highest rainfall totals likely just South of Rockford. Rain comes to an end before 6/7AM, clearing our skies out a bit for Friday morning.
Total rainfall likely will remain within a range of 0.25-0.75" for most, but some isolated totals near 1.0" or so may be possible where better forcing and thunderstorm activity lines up, likely near I-88. Further North into Southern Wisconsin, there is lower confidence on some of that thunderstorm activity, so likely on the lower end of that 0.25-0.75" range for our Southern Wisconsin counties.
All of this rain is much-needed, given the continued drought conditions that have been developing across the Stateline. The latest drought monitor from the National Drought Mitigation Center shows all of the Stateline under Moderate to Severe Drought conditions, as we haven't seen widespread soaking rainfall in nearly a month.
We dry back out into the weekend, with afternoon highs on either side of the 60-degree mark and high pressure overhead. Saturday night into Sunday morning may be chilly if skies remain clear, as overnight lows drop into the low 30s. But we begin to warm back up Sunday evening ahead of a windy and warm start to next week.
