Rainfall totals

Over the past 24 hours eastern Iowa picked up nearly a half inch of rain to an inch and a half. The rain is finally coming to an end as the cold front pushes farther east. Waterloo actually broke their daily rainfall amount yesterday with a total of 0.95”. The old record was set back in 1979 with a total of 0.77”. Here is a list of unofficial rainfall totals thus far. Fayette 1.90” Waukon 1.50” Oelwein 1.34” Eldorado 1.18” New Hampton 1.14” Marengo 1.0” Decorah 0.89” Central City 0.80” Elkader 0.50” Guttenberg 0.51” Vinton 0.51”

Strong to severe storms possible

Storm chances increase into the evening hours as the cold front pushes closer. Roughly around 7 pm storms will roll into eastern Iowa and continue throughout the overnight hours. A few storms have the potential to become strong to severe. At this time the majority of the area is under a Level One risk (Slight Risk) for strong storms. The area highlighted in yellow indicates the Level One Risk. Main threats include damaging winds and small hail. Isolated tornadoes cannot be ruled out. Heavy rain is also a concern. At this time rainfall totals look to stay around a half inch to roughly an inch of rain. Locally higher amounts are possible under stronger/ heavier thunderstorms. The rain will come to an end for the second half of Sunday, but clouds will stick around for some time. Temperatures will be significantly colder. Expect highs to only top out into the 50s.

Timing the weekend rainfall

As you’ve been noticing in the 9-day forecast this week, the rain chances haven’t gone away for the weekend. The automatic reaction may be to think the rain will ruin your plans. For the vast majority of us however, it probably won’t! Saturday – As a strong warm front lifts in from the south in the early to mid-morning, a few isolated showers may flare up. Once this front lifts north, we’ll be left with a mild, breezy and mainly dry afternoon. After 7pm, a line of showers (and maybe even a thunderstorm) will approach from the west very slowly. Plan on this rain to be around for Saturday evening and night. Sunday - We’ll need to walk a few showers out through 10am, then we are done. Clouds will likely linger for several hours after the rainfall. It’ll be cooler with upper 50s to lower 60s for highs.

Storms move in Saturday

Rain and storms are moving closer to eastern Iowa. Isolated showers are possible early Saturday, but will become more likely into the evening and overnight. A few storms have the potential to become strong throughout the evening hours on Saturday. Wind and hail are the main threats with any of the stronger storms. The majority of the TV9 viewing area is under a Level One risk (slight risk) for severe weather. Rain showers are possible during the early morning hours on Sunday. Rain will come to an end early Sunday, and then mostly cloudy skies will take over. Rainfall totals at this time look to be around a half inch to an inch. Locally higher amounts are of course possible under heavier storms.

Recent rains improve the drought

Drought conditions ranging from moderate to extreme just a few weeks ago have gotten smaller or even erased. The latest Drought Monitor issued Thursday morning shows that unusually dry conditions continue from roughly Highway 30 and south. This is because there are still some leftover effects of the very dry weather in August and September. A few small pockets of moderate drought dot the area, too, but those are much smaller than they had been. The rain coming this weekend may help even further, although it'll slow down the harvest progress again.
