Finally... Thunderstorms!

Slight changes in the forecasted path of storm systems, as well as the system stalling out over the plains has allowed the forecast to change since I last posted. Yesterday had the first round of storms come through, with some developing in eastern Iowa while others moved into the state from southwest Minnesota. Damaging winds were the biggest reports of the day over the state, however the storms that did also produce large hail did it with some significant sizes! Black Hawk county received several reports of hail larger than an inch, but the largest came in at sizes nearing softballs. One tornado report to speak of as well, 7 miles west of Haskins, IA had the sheriff report a tornado. The Davenport NWS Office also confirmed a tornado had touched down in Washington, this one has received a rating of EF1 with winds nearing 100 mph. A full report of the tornado can be found on the Davenport NWS Page.

More thunderstorms are possible today across the state, as a stationary front continues to be draped across the state from west to east. The better chances for storms looks to be in the eastern half of the state, where large hail and damaging winds, along with the threat for a tornado or two exists. Storms may develop in SD/MN and move into northern Iowa this evening as well; these also will be capable of large hail, potentially significant, as well as damaging winds and a tornado or two also cannot be ruled out if storms move into this area.
The thunderstorm chances will continue into tomorrow, as the system continues to only slowly move eastwards. The SPC has once again put nearly the entire state under a slight risk for severe weather. The risk does seem less severe as in the previous days however, nonetheless large hail and damaging winds cannot be rules out.

Temperatures during this time will be well above normal, with upper 90s in western Iowa today and near 90 in the rest of the state. Tomorrow much of the same with temperatures expected in the mid 80s where showers may begin the day, to the mid 90s where clearer skies exist. Thursday and Friday finish off the week with temperatures in the 80s throughout the state... Lows tonight and tomorrow will be in the upper 60s to lower 70s from north to south; with upper 50s to lower 60s by Thursday night and much the same expected on Friday.

Updates to the page may come a little less frequent, I'm currently working a job that is taking quite a bit of time up to earn some money before heading back to college. I'll hopefully keep up the posts to at least every other day... Thanks for reading and hope you continue to do so!
