Rain & Much Cooler Temperatures

Showers and isolated thunderstorms are moving over parts of the northwestern quarter of the state currently. Expect these showers and thunderstorms to continue over the state during the overnight hours and into the day tomorrow for portions of southeastern Iowa. Lows tonight will drop into the 50s for most of the state, however extreme northwestern parts of the state may even see some upper 40s! These cooler temperatures will continue into the day on Monday, heavy cloud cover and occasional showers along with the plain cool air will hold high temperatures well below normal. Highs should range from a few near 70 marks in southeast Iowa to the lower 60s for highs in some portions of the state! By Monday night, some clouds along with occasional showers may linger over southeast Iowa; but most of the state should be dry. Lows will once again be well below normal, with a majority of the state in the upper 40s; the exception being southeast Iowa where they should hold onto the lower 50s.

Temperatures should slowly rebound into mid-week; Highs in the lower to mid 70s on Tuesday increasing to the mid to upper 70s on Wednesday. Lows will also make it out of the 40s and slowly rise during the mid-week stretch. Lows in the lower to mid 50s on Tuesday night; Wednesday night will range from the lower 50s to upper 50s, although a few upper 40 marks aren't being ruled out across the northwestern quarter of Iowa.

The latter part of the week will once again bring in the chance for rain showers over the state. Currently it looks as if late Thursday and especially Thursday night will bring in the showers over western & central Iowa, leaving eastern Iowa by afternoon on Friday. Highs will once again be impacted greatly, falling back well below normal; Thursday highs in the mid to upper 60s with some areas of extreme southeastern Iowa still seeing 70s ahead of the clouds/showers. Friday will have highs struggling into the 60s for the most part, ranging from 60 in the northwest corner to the upper 60s in the southeast portions. Lows on Thursday night could be downright cold! Mid to upper 40s, with a few 50s over the state and look for them to drop even further Friday night. Upper 40s in the southeast, to mid 40s over the southwest. Lower 40s for the northern half of the state, but wouldn't be surprised if a couple lower lying areas in northwest Iowa can drop into the 30s! Yes, some temperatures flirting with the frost point are possible by this weekend...

More updates later this week on the possible frigid temperatures for September; including the possibility of frost.
