As expected, temperatures hit the mid-40s on Friday…despite rainy conditions. But the passage of a cold front this evening, marked by a flurry of rain/ice, brings an icy change for the weekend.
Temperatures drop steadily overnight and reach freezing point by midnight and teens above/below 20 by sunrise on Saturday. This will cause some refreezing of moisture not evaporating from the wind on the roads/sidewalks as patches of ice develop on the untreated surfaces.
This wind makes it “feel” 30°-40° colder as wind chills peak in the 0°-10° range. The recovering cold from Lake Michigan, combined with the upper air lift, is producing scattered lake effect flurries/snow showers…and enough in places for dusty/slippery roads Saturday morning.
These should subside later in the afternoon as the wind moves away from central Indiana. Saturday evening clears up and cools down to near single digits on Sunday morning.
Most models remain consistent on a mower, albeit weak, moving through central Indiana on Sunday with light and more stable snow cover in the afternoon/early evening. This will suffice for a dusting to locally 1″ in some spots. This will occur with temperatures in the teens/under 20’s, so it is conceivable slip spots could develop on Sunday afternoon.
