Cool & Calm July

Iowa has been both on the cool and calm side of the weather for the month of July despite a few events that have hit some parts of the state hard, including a few tornadoes and some very damaging hail across northeast Iowa last Friday. A rough and quick look at the mean temperatures over the month of July indicates that it is likely to be the coolest since 1992. For example, Estherville has a mean temperatures thus far of 66.8 degrees, which is second coolest since 1951!

The final day of the month looks to be just at, or just below normal for the state. We'll also get a good chance of some thunderstorms for the end of the month across at least the western half of the state. The severe weather threat appears minimal at the moment, but some small hail and gusty winds is not out of the question for the western third of the state. An update may be necessary if the potential for severe weather tomorrow night does increase...

We'll clear off and be near or just below normal for high temperatures once again through next week; low temperatures will be just below normal. A chance of thunderstorms and showers will work its' way back into the forecast for mid-week, otherwise it appears dry through the first week of August. The long range forecasts do indicate the possibility of a good ridge building into the central US through the first weeks of August which may finally lead to some above normal temperatures!
