Today's Storms... More Storms...

Scattered thunderstorms worked across the state this morning and are continuing into the early afternoon hours over central and eastern portions of the state. Cloud cover has also hampered the warming that was expected over some parts of the state, this is also taking away from the potential severe weather risk that central/eastern Iowa had. A cold front is working across the state, currently past the northwest corner of the state and should be over central Iowa by mid-afternoon. Some clearing ahead of this front will allow for a slight warm-up and allowing some marginal instability. Whatever instability that can occur along with the lift along the front and marginal moisture returns should allow for redevelopment of thunderstorms over central Iowa and northward. These storms may be capable of large hail and damaging winds, although an isolated tornado is not being ruled out at this point the best risk for them will be north of the state line into MN and WI. Expect thunderstorms to move across central Iowa and through eastern Iowa by early tomorrow...

Highs today will be in the mid 60s over western Iowa where the cold front is already passing through, mid 70s could be reached over eastern Iowa. Lows tonight in the mid 50s possibly where the cold front has not yet passed, otherwise 40s for lows over much of the state. Clearer skies for Sunday, with highs in the low to mid 70s across the state. By Sunday night a warm front is forecasted to begin moving over the state, this is going to bring some thunderstorm chances into the forecast for southern Iowa on Sunday night. Otherwise lows in the 50s are expected throughout the state. By Memorial Day the front has continued its' move across the state, although bringing much warmer temperatures and moisture, it will likely bring isolated thunderstorms over much of the state. If you can avoid those, you're in for a nice day with highs in the mid 70s to lower 80s. Lows in the upper 50s for northeastern Iowa on Monday night, with other portions of the state in the low to mid 60s.

Our next big system will move in late Monday night, but especially Tuesday as another cold front sweeps across the state. Thunderstorms may work over the area early Tuesday morning from their initiation in the Dakotas. Redevelopment along the cold front is likely over western Iowa at this point, with the potential for severe weather. These thunderstorms will likely work across the state Tuesday night and possibly into Wednesday for eastern Iowa. More details on this threat will be worked out as it nears...
