Here’s the latest on the first accumulating snow of the season…
Winter weather advisories have now been issued for several Indiana communities for Sunday night through Monday morning. Overall we are expecting 2 – 4 inches from an area stretching from Muncie down to Seymour and over to the Bicknell along the Illinois state line. Indianapolis, Bloomington and Columbus are all included under the advisory. While Hancock, Johnson and Morgan counties are included in the advisory, Boone, Hendricks and Hamilton are not included. Those communities can still expect snow in the more manageable 1 – 2 inch range.
While the big snow isn’t expected to arrive until tomorrow afternoon into the evening hours, Light snow will fall tonight and will likely be enough to cause some slick spots on area roadways. A dusting to minor accumulations will be possible overnight. Overnight temperatures will fall to the mid to upper 20s tonight and won’t be as cold as the teens we saw this Saturday morning.
Sunday – Monday
The big question everyone wants to know about is just how much snow will we see. I wish the answer was a simple one but it isn’t. I fully believe we will see at least one community recording more than 5 inches of snow! It will be isolated in a narrow band with the most likely spot being just south of I-70. Other areas along and south of I-70 in the advised area are expected to see 2 – 4 inches of snow. There will be a wide variation from community to community on just how much snow you will see.
The reason for the big snow projection is due to an area of low pressure expected to track through the state on Sunday night. This system will grab onto some well-timed gulf moisture moving north just ahead of the low. Down south, where it’s significantly warmer, thunderstorms may actually develop as there is a marginal risk for severe storms in Louisiana and Arkansas. That’s now the lowest risk category.
With the uncertainty with just how much moisture we will see ahead of the system and questions still on the lows exact track there seems to be a wide variation with regards to snow totals and location. Over the past 12 hours snow projections have gone up as the amount of moisture available has gone up while the track has stayed relatively close to where it has been all along. That track is mainly along and just south of I-70. The difference tonight in the official track is the inclusion of Muncie and places along I-69 now south of Muncie now in the bull’s-eye for seeing 2 – 4 inches of snow.
Behind the snow:
The coldest weather yet and the coldest weather since the third and fourth of March will arrive behind the snow on Monday night and Tuesday morning. Overnight lows on Tuesday should fall to the low teens or perhaps even single digits depending on how much snow is on the ground. Wind chills will make it feel like temperatures are near 0 for those having to stand out at the bus stop or work outdoors for the day.
