Clouds in central Indiana will continue to thicken during the overnight hours as a fast-moving low pressure system dives into the state Friday afternoon. Moist air is also lifting north from southern Plains as a upper low pressure system moves toward the Tennessee valley. The two weather features will come together over Indiana bringing the threat of snow.
As the systems merge over the state Friday, light snow will break out around sunrise. The combination of the two system should send a coating of snow to eastern Indiana, Ohio by early afternoon.
Light snow should become more wide-spread from 5AM through 8AM
Accumulation from the city east to the Ohio border is likely through noon.
The snow will end very quickly from late morning on east to west. Very little snow accumulation is expected from Indianapolis west back to the Illinois state line.
The average of 5 computer models came in at about .08″ for the city. That is not a lot of snow but given the cold air this amount of liquid could fluff up to around 1″ in the city. Higher snow amounts of up to 2″ is most likely east of the city heading toward Ohio, where the system has had more time to get organized.
WINTRY WEATHER BACK SUNDAY
As arctic air retreats late in the weekend, mild and moist air will overspread the state by afternoon. Light rain is likely to develop Sunday as air temperatures at the surface remain near or below freezing. There is chance for a period of freezing rain late Sunday/Sunday night before milder air moves up for Monday.
The jet stream lifts north Tuesday bringing more rain but a burst of mild air for at least one day. Tuesday afternoon temperatures could climb back into the middle 50’s. It looks to be a one day stint as arctic air returns Sunday.
