INDIANAPOLIS (WISH) — High temperatures will run 10-15° below average through early next week.

Thursday:

A large area of low pressure continues to spin over the Great Lakes, keeping conditions cloudy, cool, breezy, and at times damp. Expect today’s weather to be very similar to Wednesday’s.

Isolated showers are expected to develop this afternoon. As on Wednesday, coverage will be limited, and any rain should be relatively light.

High temperatures will reach only the upper 50s to lower 60s. Blustery winds with gusts up to 20 mph will make it feel colder.

Thursday night:

Showers will diminish this evening and overnight. With Canadian high pressure settling in overnight, expect clouds to break. Fog is likely to develop in the western portions of the state overnight.

Temperatures will be chilly, with overnight lows falling to the low to mid-40s.

Friday:

Despite below-average temperatures, Friday (Carb Day) looks favorable. Expect mainly dry conditions with partly cloudy skies. High temperatures will reach the mid-60s.

Saturday:

The start of the holiday weekend also looks relatively quiet, with partly cloudy skies and slightly warmer temperatures. Highs will reach near 70°F across much of central Indiana, still about 5°F below average.

Indy 500:

Cloud cover will increase on Race Day (Sunday). There’s a good chance of precipitation in the southern half of the state, mainly south of the I-70 corridor. Rain is likely after 2 or 3 p.m. While there’s optimism that Indianapolis Motor Speedway may stay dry, the proximity of rain warrants mentioning the chance of showers for the second half of the race.

Sunday will remain cloudy and cool, with high temperatures in the mid-60s.

Memorial Day:

A similar pattern will occur on Memorial Day. Another wave moving in from the north and west will bring rain chances to the southern half of the state, likely in the afternoon.

High temperatures will reach the mid-60s.

Extended forecast:

The cool pattern continues into the short workweek, with highs failing to get out of the 60s. Scattered rain and storms will also be possible through the middle of next week.
