Mississippi River on the rise

Runoff from rain to the north is causing the Mississippi to come up. This will lead to flooding along parts of the river for the Memorial Day weekend. If you plan to go boating on the Mississippi over the weekend, be aware that the current will be faster than usual. Also be on the lookout for debris that the swollen river may have picked up. The following are the river forecasts as of Wednesday afternoon: Lansing: Remain below flood stage. Lynxville: Remain below flood stage. McGregor: Minor flooding. Rise above flood stage Wednesday night and crest at 17.8 feet Saturday, then remain steady through Tuesday. At 16 feet, the Washington Street Bridge to Saint Feriole Island begins to flood and is closed. At 17 feet, access to parks near the river in Prairie du Chien is affected.

Finally May like weather

Considering we’re still on the back side of the low pressure system, we’ll still be dealing with a few sprinkles here and there this afternoon and early evening. On the bright side, literally the bright side the low will move out of here and leave us with some sunshine for Thursday. Partly to mostly sunny skies will take over eastern Iowa and thanks to the sunshine high temperatures will warm back into the 70s. The warmth stays with us throughout the end of the week and into the weekend. However clouds roll back into the area and a few showers and storms pop back up into the TV9 viewing area. Storms will be very isolated throughout the weekend. It won’t be a wash out by any means. Go ahead and make plans, but just be sure to keep an eye on Pinpoint Doppler Radar. Keeping us on a positive note; at least we won’t have to water the grass and plants all that much!

Warming back up with rain chances for Memorial Day weekend

After a few chillier days early this week, our temperatures will warm back up to near normal levels just in time for the weekend. However, we’ll also have to watch for showers and storms. We’ll be breaking out of the cloudier and cooler weather pattern once we move past Wednesday. Winds will gradually return out of the south, bringing back milder air to eastern Iowa. As the southerly winds continue, they’ll also be bringing back moisture to eastern Iowa, especially by Friday. This will increase our chances for showers and storms. The entire weekend doesn’t look like an entire washout, so there’s no need to cancel the outdoor plans yet. As we move through the next few days, the timing of storms will become more apparent. Stay tuned!

Be weather-safe when boating

This is National Safe Boating Week. With summer fast approaching, it’s important to remember weather safety when being out on the water. Lightning is particularly hazardous for two reasons. First, lightning tends to strike taller objects; if you’re out in the middle of the water, you are the tallest object around. Second, water conducts electricity; lightning striking the water nearby will send the electrical current across the water. One myth is that lightning strikes only when it’s raining – this is false. Lightning can strike 15 miles away from a thunderstorm. And if you can hear thunder, lightning is already close enough to hit you. Practice the “30-30 Rule.” Go inside when there’s lightning, and stay inside for another 30 minutes after you’ve been able to count a full 30 seconds between a flash of lightning and the rumble of thunder. All thunderstorms have lightning by their very definition. However, not all thunderstorms are intense enough to warrant a severe thunderstorm warning, which comes when they produce 58 mph winds and/or quarter-sized hail. Strong winds and large hail pose their own dangers, but you can’t rely on a warning message to alert you to the threat of lightning. The KCRG-TV9 First Alert Weather app does offer lightning notifications; if you have it, check your app settings to ensure they’re turned on.

Cool stretch of days ahead

With showers and clouds expected across eastern Iowa, along with northerly winds, temperatures will be running below normal through Wednesday. In the upper levels of the atmosphere, a deep trough will dig deep into the eastern half of the country. This means cooler air aloft will funnel into the Midwest and Great Lakes regions. With winds out of the northwest and northeast for the next few days, temperatures will struggle to warm in the afternoons. Highs on Tuesday are only forecast for the middle 50s with Wednesday only a few degrees milder. These numbers are close to 15 degrees below normal for late May. Slightly milder and more seasonable air is expected by Thursday, as the trough lifts back north, allowing warmer air to move back into the area.
