Zionsville, IN After waking up to half an inch of snow, sunshine engulfed most of the region Tuesday. The vitamin D didn’t help temperatures moderate much as highs were more like mid to late December as opposed to mid November. We discuss a warming trend below, after a frigid start to your Wednesday.
Wednesday: Mostly sunny; 19/ 39
A strong area of high pressure will move overhead Wednesday and help supply a mostly sunny sky. Despite the sun, it’ll be another unseasonably cold day. Many outlying communities will begin the day in the upper teens before rising into the upper 30s to near 40 by afternoon- a solid 15 degrees below normal.
Thursday: Partly cloudy; 28/ 49
The same high pressure that will be directly overhead Wednesday will begin to move east Thursday. This will put our region in a southwesterly air flow and allow temperatures to begin moderating. After another cold start, highs will push towards the 50 degree mark Thursday afternoon.
Friday: Partly cloudy; 35/ 52
We’ll wrap the work week up with a few more clouds and temperatures still slightly cooler than normal, though much milder than those we’re dealing with now.
Saturday: Turning cloudy with PM showers (0.20″); 40/ 59
Model data continues to hint at increasing clouds and the threat of afternoon light rain. We’ll initially have to overcome the dry air mass in place, but by afternoon/ evening we should have scattered showers beginning to impact central portions of the state.
Sunday: Cloudy with rain likely (0.45″); 52/ 60
More widespread rain will arrive for the second half of your weekend. Highs will approach 60 and should we see any sunshine (not looking likely at this point), temperatures could go into the lower to middle 60s. While temperatures will be much warmer we’ll have to contend with rain Sunday.
Monday: Showers and possibly a thunderstorm (0.50); 34/ 63
A strong cold front will blow through the state Monday evening. Out ahead of the front, an impressive surge of warmer and more humid air will move north and encompass central Indiana during the day. In fact, latest model data suggests dew points reach the lower 60s Monday. The combination between the warmer, more humid air in place and an impressive surge of arctic air behind the front could team up to produce a clap or two of thunder with the moderate to heavy rain threat Monday afternoon as the front moves through. Temperatures will then crash Monday night.
Tuesday: Scattered snow flurries; 24/ 34
The big story Tuesday will be the much colder air mass rushing into the state on strong and gusty northwest winds. Just enough moisture may linger to create the chance of scattered snow flurries.
