A Severe Thunderstorm Watch has been issued area-wide through 7 PM.
Today: Finally, widespread rainfall is in the forecast today. This morning has started off mostly dry with ample sunshine. Now, showers and storms are beginning to develop and will pick up in coverage and intensity through the late morning and afternoon. Most in eastern Iowa will pick up some rain, some will see heavy rain with a slight chance of severe storms, damaging wind gusts the main threat. The clouds and rain should keep the high heat away with highs in the mid to upper 80s. It will still be humid keeping our heat index in the low to mid 90s. We will have a south wind at 5 to 10 mph.
Tonight: Showers and storms come to an end in the evening with decreasing clouds following. Open up the windows tonight – lows drop to the mid 60s with a northwest wind at 5 to 10 mph. Humidity will start to fall.
Friday: Skies will be mostly sunny with highs in the mid to upper 80s. This time, humidity should be lower with dew points in the mid 60s thanks to a northwest wind at 5 to 15 mph.
Weekend: We will have a couple chances for rain and storms, one coming with a complex of storms moving somewhere through Iowa on Friday night. Right now I have a 20% chance for that. Otherwise, some scattered showers and storms will be possible on Saturday with partly cloudy skies. We look dry and partly cloudy on Sunday. Temperatures will generally be in the mid 80s with lows in the mid 60s. Humidity will be higher on Saturday before dropping down on Sunday.
Next Week: Heat looks to build back in with highs in the upper 80s and low 90s. Humidity will certainly become higher, driving heat indices up. There will be a few sporadic rain/storm chances in between the sunshine and partly cloudy skies. Best chances look to be Monday night, Tuesday night and Wednesday, and Thursday night through the weekend. Heat may become extreme for next weekend but for now we have highs in the low 90s.
