Ryan Martin’s Indiana Ag Forecast for September 18, 2017


Rain and thunderstorm action moved into the state last night with an approaching cold front. That front still lingers over the state today and will meander through. This will keep some scattered light rain over us today, mostly ranging from a few hundredths to .3”. Coverage will be about 60%. The action will be very hit and miss in a given time frame, favoring northern Indiana this morning and the central and southern Indiana more this afternoon. Temps will remain relatively warm. 

Tomorrow is where we see changes in our original forecast thought process going back into last week. WE see a secondary wave of moisture moving through the region tomorrow, centered farther north, over Michigan and the Great Lakes, but still, enough of a wave and a front to drag moisture over the entire state. WE look for rains tomorrow to range from a few hundredths all the way up to potentially .7” near the IN/MI line. Coverage of rains will be about 70% of the state. That will put 2 day combined totals at .1” to 1.0” over about 85% of the state. So…good rains for everyone, thanks to the extra day of rain. The map above shows cumulative rain totals through Wednesday morning.

We should dry down starting Wednesday. Some models are trying to keep some minor moisture around Wednesday, but we think that will be tough. Clouds will be around, but we are not calling for new rain. The dryness continues through the weekend and early next week. Early next week we see models trying to back some moisture in from the east, likely the remains of a tropical system. Right now, it looks like the moisture only makes it to OH, meaning we should stay dry right on through next week as well. But, it is a scenario we are watching. For now, we will look for a mostly dry finish to the month of September…meaning this rain to start our week this week needs to be looked at as the “finishing” rain or crops, and then we look at the rest of the 10 day period to have excellent dry down to move harvest along.

Temps should be normal to above normal this week, and mostly normal next week. That means we see no threat of frost through the rest of the month of September, and we remain on track to see at least a normal first frost potential in October. We can’t say we are looking at any kind of significant extension to the growing season, but we shouldn’t cut it short either.
