Timing so far looks pretty good for storm to develop across central and eastern Iowa during the afternoon hours. There should be plenty of instability aloft for storms to tap into and parameters look good for strong damaging wind gusts. There should be a minimal threat of tornadoes but right now the primary concern is strong winds and perhaps some large hail.
Once this storm system moves out Friday Night we should stay quiet until late Monday and into Tuesday. That’s when a more powerful cold front will pass through the state, threatening to bring another round of strong storms. At this time it’s too soon to tell the extent of that threat, but there are indications we could see a more organized severe weather event that what we’ll see tomorrow.
The other good news from Tuesday’s cold front is drier and cooler air behind it. But for now we’ll focus on the humidity and severe threats over Iowa in these next 48 hours. Look for more updates when needed later this afternoon.
