Rain dominates the state today after a very “iffy” overnight period, especially up north. This morning we are dealing with a little more ice after the last 12 hours of freezing rain from US 30 northward. Action switches over to all rain quickly this morning by mid-morning, and then the rain continues through the rest of the day. Some areas north of US 30 will end up with ice totals this morning up to .15”, then rain totals today will be from .5”-1.5” However, near and after sunset tonight, precipitation continues, and we can see a switch back to light, wet snow. This can lead to a coating to 2” with coverage at 70% of the state. The highest totals will be in east central, northeast and north central Indiana. Snow ends from SW to NE through the overnight. Winds will pick up, though overnight tonight. The map at right shows cumulative rain for today and tonight through tomorrow morning.
We expect a mix of clouds and sun tomorrow as the remains of today’s event move off to the east. Winds will subside through the day, but we may still see some wind chill problems, at least early on. While we expect cooler temps, we should end up near normal. Partly sunny skies continue through Thursday.
Friday developments are a case study on why it is not smart to really ramp up potentially large winter systems a week in advance. Strong low pressure is still set to move across the state and the eastern corn belt. The low still is on a SW to NE trajectory. However, model runs this most recent time around have seemingly lost all moisture potential. We are not changing our forecast yet still looking at the potential for rain, ice and snow, but track and available moisture remain as the most important variables. We are not going to step out on any of those this morning, but will continue to watch the storm potential.
Windy and colder for Saturday, and then we stay chilly Sunday and Monday. Temps below normal. We should see some sub-zero lows for the morning of Presidents day.
Tuesday the 19th and Wednesday the 20th are picking up a little more snow in this morning’s forecast. We see snow developing form midday forward next Tuesday, and it continues through at least midday Wednesday. 1-3” of snow can fall on Tuesday, and another coating to an inch for Wednesday. Snow coverage will be around 80% of the state.
For the extended period, partly to mostly sunny skies return for next Thursday through Sunday. Colder air with another snow event arrives for Monday the 25th and goes through Tuesday the 26th. Accumulations are likely.
