TRACKING: Potential for Severe Weather Today

Remaining Ad Time Ad - 00:00

A round of showers and storms brought heavy rain, lightning and some small hail to extreme portions of northeast Iowa. Another round of showers and storms are expected to develop later today.

A cold front will be tracking south into Iowa this afternoon. Highs will be warm in the 80s with some locations in southern Iowa reaching to near 90 degrees. Dew points will be in the 60s so it will definitely feel warm and muggy across Iowa. This heat will help to hold off on storm initiation across eastern Iowa until this evening and overnight.

Location of storm development will depend on where the cold front stalls out this evening. Current models indicate that it will most likely be between HWY 20 and I-80. Timing of initiation is expected to be after 6 PM. Once the storms develop, they could quickly become severe. The main threats are expected to be large hail, damaging winds, dangerous lightning and heavy rain.

Some locations may see heavy rain continue for an extended amount of time. In total, over a half inch of rain is possible with around an inch or more possible in stronger storms. The potential for flooding will be monitored.

Scattered showers and storms will continue throughout the overnight into Friday though the severe weather threat should diminish after midnight. Lows tonight will be in the 50s to 60s and winds will be from the northeast at 5-15 mph.

Tomorrow’s highs will be dependent again on front placement. Areas south of the front will be warm in the 70s to near 80 degrees. Areas north of the front will be on the cooler side with highs in the 60s. Scattered showers and storms will likely be ongoing in the morning with heavy rain and lightning the main threats. Winds will be breezy from the east at 10-20 mph.

Rain chances will continue into Friday night but this round is dependent on front placement and where storms develop out west. We may not see any of this rain until Saturday morning.

The low pressure system will track east and bring this nuisance of a front with it. However, with the low pressure system tracking through during the afternoon, severe storms are again possible Saturday afternoon and evening. Be sure to stay weather aware throughout the day if severe storms should develop.

Rain continues into Sunday before this system finally tracks out Monday.

Another strong storms system will bring another threat for rain across eastern Iowa beginning Tuesday. Needless to say, flooding may be a concern into the weekend and next week along with severe weather threats. Be sure to stay updated on upcoming forecasts for the latest.
