Heavy Rains

With some decent thunderstorms providing rainfall over the state during the weekend, the threat of heavy rains is once again in the forecast for the next system to pass over the state. A strong low pressure system will move south of the area, allowing for potentially significant severe weather over areas of the central/southern plains. But, for the state of Iowa, being just north of the low will set portions of the state up for significant rainfall.

Showers/Thunderstorms likely to begin in the southwest by late tomorrow morning, with movement northeastward allowing them to overtake much of the state by Tuesday evening. Those lucky enough to not be rained out during the day will see the rain begin overnight. These showers/thunderstorms will likely last throughout the night and into Wednesday morning, with the northern half of the state seeing an end by 10 am, however the southern half or third of the state may see rainfall linger much of the day as the low continues to spin just south/southeast of the state. The southern third of Iowa is thus likely to see the heaviest rainfall, with current forecasts of nearly 2 inches or more. Northern portions of the state will also see some significant rains, although only on the order an inch or so...

Once this system passes through, temperature on Thursday will be in the lower 60s throughout the state. Despite this day below average, temperature will continue to rise to above normal standards by the weekend. Mid 60s to lower 70s from northeast to southwest on Friday; 70s throughout the state on Saturday with the highest values once again over the western portions of the state. Finishing off the weekend, high temperatures over western Iowa will likely be in the 80s once again with the rest of the state also very warm in the 70s. Lows during this period will range in the 40s on Thursday/Friday night, warming into the upper 40s and lower to mid 50s for the weekend.
