Ryan Martin’s Indiana Ag Forecast for December 22, 2017


Scattered light precipitation moves across the state today, but really has very little moisture to truly work with. Right now we will look for a few hundredths to a tenth or two over 60% of the state. A lot of the moisture may end up coming out as clouds and spotty drizzle. Still, we can’t call the day precip free, even if action is very, very light. Better action develops overnight tonight into tomorrow. However, we continue to see a very significant focus on southern areas. We are leaving rain totals oat .1” to 1”, and that upper end range total will be limited to areas right along the river. Bigger rains will be seen in KY, but probably do not move north with any regularity. However, we also see a bigger disparity developing from north to south. It is possible that a large part of northern Indiana, from I-70 northward gets little to no rain.

We are dry from Saturday midday through Sunday morning. Weak high pressure acts as a bit of a place holder in there while cold, arctic air starts to blast in. We should see some sunshine in there, particularly Saturday afternoon.

Sunday midday snow arrives over the state. Our official forecast is for 1-3 inches over the northern third of the state, and a coating to 2 inches elsewhere. We see coverage at 90% of the state with at least some snow. However, those snow totals are not too bad, and should not cause major travel problems. The snow is done by early morning Christmas, and we should see sun come back quickly for the balance of Christmas Day. The map shows potential 24 hour snow totals ending Christmas morning around sunrise.

Dry Tuesday through Thursday with high pressure in control and cold air continuing to batter the region. Sunshine should dominate for Tuesday and Wednesday. Thursday night and Friday we have another push of snow for the state, with accumulations likely in the 1-4 inch range. Statewide coverage of snow will be 75%.

While cold air stays, we are starting to see our New Year’s Eve weekend storm event come back into focus. A strong low wants to lift northeast for next Saturday, the 30th. It has ample moisture with it, and could trigger significant snows over the state. Models have been flip flopping on this system for several days, so it’s nothing to get too super excited about yet. But, it is something we are monitoring, as it may send 2017 out with a flourish and start 2018 with a bang.
