INDIANAPOLIS, Ind. (Feb. 29, 2016)--Good Monday afternoon and happy Leap Day! It's been a sunny afternoon with temperatures in the 50s. Things will be changing as we go through the day Tuesday.
While Tuesday marks the start of meteorological spring, it won't feel like it as a strong cold front moves through the region. The first front will move into north-central Indiana tonight and stall to the north of Indy. Temperatures will dip to the upper 30s in the circle city tonight. Winds will be light out of the southeast as clouds increase overnight.
Temperatures will quickly rise to the upper 40s and low 50s through midday with winds increasing out of the southwest. This is in advance of the secondary cold front. Rain will spread in late morning and continue through the afternoon.
There will be a chance of thunderstorms across southern Indiana. Rainfall amounts of 0.25-0.50 are possible in Indy with locally higher amounts in thunderstorms south. As the secondary cold front swings through the area between 4 and 5 p.m. Tuesday, expect rain to change to sleet or snow by 5 p.m. in Indy. Areas across north and western Indiana will see snow sooner. Winds will also pick up with gusts to 30 mph late day. Temperatures will plunge to the 30s in the late afternoon/evening behind the front.
Light accumulations of snow are expected at this time, mainly on grassy surfaces as the ground is warm. It appears that a trace to 0.50 inches of snow is possible in Indy with higher amounts of 1-2 inches across northern Indiana. Temperatures will only be in the mid-30s Wednesday with snow showers north and east of Indy in the morning. Another wave of rain/snow mix will move through Thursday and we round out the work week with a mostly sunny sky on Friday.
