Marengo Weather: The Week Ahead

The week opens warm and humid. The high reaches 83°, three degrees above the June average of 80°, after a 63° morning. A stray sprinkle is possible early, but at a 16% rain chance the day stays mostly dry. South wind around 15 mph and UV near 8 make it feel like full summer, so reach for the sunscreen and water. Enjoy the dry hours. They are the easiest ones until the weekend.

The wettest day of the week. Rain is close to a sure thing at 90%, with drizzle and steadier downpours likely through the day, so move outdoor plans indoors and keep an umbrella handy. The high still reaches 83° behind the clouds, three degrees above average, and the morning starts mild at 64°. UV drops to a 5, the lowest reading of the week. A soaking for the garden, if not for your plans.

Warm, muggy, and unsettled. The high climbs to 86°, six degrees above average, and the 69° morning hints at the humidity building all day. Thunderstorms are likely at a 67% chance, most active in the afternoon heat. Wind stays light at 9 mph, the calm before a more active stretch. Keep an eye on the afternoon sky if you have outdoor plans.

The hottest day of the week. The high peaks at 88°, eight degrees above the June average of 80°. The 72° morning is the mildest start of the week, and the humidity makes the afternoon feel warmer still. Afternoon thunderstorms are possible at 41%, with wind picking up to 20 mph ahead of Thursday's front. Hydrate, find shade after midday, and get any strenuous work done in the morning.

The day the pattern breaks. A strong cold front pushes through with the windiest conditions of the week, wind climbing to 31 mph, and a 51% chance of thunderstorms along the front. The high still reaches 86° ahead of it, but the air behind the front turns noticeably cooler and drier, and the overnight low falls to 61°. Bring in anything in the yard that can blow around, and expect storms to clear by evening. This is the week's turning point.

Cooler and calmer behind the front. The high settles to 78°, two degrees below average and ten cooler than Wednesday's peak, with a fresh 55° morning, the crispest start of the week. Skies stay mostly cloudy with a lingering 51% chance of a shower, but the wind eases to 9 mph and the humidity is gone. A welcome reset after the stormy stretch.

The week ends mild and mostly dry. The high recovers to 81°, one degree above average, after a 61° morning, with only a 22% chance of a stray shower. Clouds break for some sun, the wind stays light near 10 mph, and the air feels comfortable rather than muggy. The best outdoor day of the back half of the week.
