Marcus’ 4 a.m. Wednesday forecast INDIANAPOLIS (WISH) — Active weather this week, with widespread rain expected on Thursday. As temperatures plummet from the 50s to the 20s overnight, there is a risk of flash freeze and patchy black ice by Friday morning. Today: A weak boundary is wor king through the state this morning, sparking some light drizzle across the area. While air temperatures are hovering around 40°, road temperatures are a little closer to freezing, so some areas of black ice could be possible for untreated and lesser traveled roads this morning. Meanwhile, clouds should break later today with warmer temperatures. Highs will hit the mid 40s. Wet and windy Thursday: A cold front approaching from the north will bring gusty winds and rainfall to the region on Thursday afternoon. Wind gusts are predicted to reach between 25 and 35 miles per hour ahead of the storm system, while mild temperatures this week will contrast sharply with the anticipated cooldown. Rain will develop in Central Indiana on Thursday, becoming moderate to occasionally heavy, particularly in southern and eastern areas. Minor flooding is possible in low-lying regions as precipitation accumulates. By Thursday evening, the weather will shift dramatically as two cold fronts move through, causing temperatures to drop quickly. Flash freeze potential Friday morning: As the first front moves through late in the afternoon, the rain will taper off and temperatures will begin to fall into the 30s and lower 40s. The second, stronger front will push temperatures down to the 20s and upper teens, creating conditions ripe for a flash freeze. The rapid temperature drop could result in black ice formation by Friday morning. Snow showers may also occur overnight into Friday morning, with minor accumulations of up to half an inch. 7 day forecast: Looking ahead, milder weather is set to return over the weekend, with highs expected to reach the 40s. Even warmer temperatures will follow into Christmas week. ...read more read less
