As temperatures fall close to the dew point temperature and winds turn light tonight, there may be some areas of freezing fog. Visibility will drop in spots and we'll watch for patchy slick spots, especially on bridges and overpasses.
Sunday afternoon will bring sun and clouds with highs in the mid-30s and a south, southwest breeze 10-15 mph. In fact, Sunday will mark the first time in nine days that Indy will be above freezing.
Clouds will increase Sunday night and Monday will bring rain in the afternoon as a low-pressure system lifts north out of the Plains. Winds will pick up 10-20 mph with higher gusts Monday evening as temperatures soar into the mid-40s. There may be enough instability to have thunder around Monday night. A strong cold front will move in early Tuesday and drop temperatures from the mid-40s after midnight into the 30s by daybreak Tuesday. Expect a changeover from rain to snow showers early Tuesday.
Model data is suggesting only a dusting to a couple of tenths inches of snow for parts of central-northern Indiana on Tuesday. We'll watch this but for now, I'm not expecting much considering the ground will be relatively warm.
Speaking of snow, Indy has seen 7.7 inches of snowfall since July 1, 2015 with 5.8 inches of that snow falling this January. The dates we look at to compare actual snow to the average are July 1 and Dec. 1. However, if I just use Dec. 1, then we can't account for the snow that occurred in Nov. 2015.
A nice warm up will come into next weekend where highs may touch the 50s in spots. --Danielle Dozier
