DES MOINES, Iowa – Our holiday weekend forecast is going to mark a return to a more active weather pattern after a couple of gorgeous days to wrap up the week. The good news is the weekend won’t be totals lost to rain and storms, but the second half will likely take some creative planning if outdoor events are where you are planning to spend your holiday.
Saturday will likely be the best bet for dry weather across the state. We will see mainly cloudy skies across the state throughout the day, with a few showers mixed in, especially west of I-35. Most of the showers should remain very isolated and fairly light. While we may not see much more than a few peeks of sunshine during the afternoon, the rain will be light enough over the northwest half of the state to keep from disrupting most plans.
Sunday will be another story. As an area of low pressure pulls to the north, it will bring with it periods of rain and thunderstorms, starting in the early morning hours of Sunday and continuing off and on through the day. This system will have an open door to pull moisture from the Gulf of Mexico, so locally heavy rains will be possible on Sunday, with 1 to 2″ not out of the question. Prepare to spend much of Sunday indoors. Aside from the heavy rain potential, Sunday’s storms do not look to have much of a severe weather threat.
Monday will be a bit better, but may also provide a chance for storms. A few lingering showers from Sunday will be possible up through 7 a.m., and then we should at least a period of dry weather, and possibly a bit of sunshine into early Monday afternoon. The midday/afternoon break should provide a nice window for outdoor festivities on the holiday.
At this point, there will be a chance for storms to redevelop late in the afternoon into the evening, and some could be strong, particularly in Southern Iowa. Much will depend on how quickly the low and cold front work east on Monday, which could lessen the chance for PM storms on Monday so continue to monitor the forecast through the weekend, especially if you are planning to camp or enjoy the waters on one of our lakes.
