Ryan Martin’s Indiana Ag Forecast for December 31, 2018


Low pressure moves across the state today, along a line from Effingham, IL to Decatur, IN. This will bring significant rains to all areas through the day today. Rains are already underway this morning in southern Indiana, and by midday the entire state will see some amount of moisture. Rains continue this afternoon and evening and should be wrapped up by closer to midnight. South flow up the frontside of the low will keep temps warm, even above normal through most of the day and this evening, meaning all precipitation will stay liquid. We look for rain totals to be from .5” to 1.5” with 100% coverage statewide. New Years eve festivities will require the umbrella. The map above shows precipitation through midnight tonight.

We turn drier starting tomorrow, but much colder air is also on the way to start off 2019. We will still have a mild feel to start the day, but temps turn colder through the day. Clouds give way to sunshine. We stay partly sunny for Wednesday and Thursday, although clouds will be on the increase through Thursday. Temps slowly move higher Thursday as well.

Our next round of precipitation moves in over night Thursday night. We expect rain and snow from US 24 southward. Liquid equivalent precipitation will be from .1”-.5” in that part of the region with coverage at 80%. We think that the predominate precipitation type will be rain from I-70 southward, but from I-70 up to US 24, there can be a mix of rain and snow. This will also be where the precipitation is the lightest. Friday may start with a bit of snow along and south of a line from Fort Wayne to Terre Haute, but we do not expect a lot of snow. That threat ends by late morning, and then we should turn out partly sunny for the balance of Friday, but colder again.

The weekend looks good. We anticipate sunshine to be in full control, and dry weather holds through Sunday night. Clouds will increase Monday midday and afternoon and we might even see a few hit and miss showers Monday afternoon and evening

Better organized rain shows up Tuesday and continues into Wednesday the 9th. Temps climb again and will be high enough to allow for all liquid. We expect .25”-.75” rain totals with coverage at 90%.

The extended period starts of dry, with no new precipitation and plenty of sunshine for late the 9th through the 12th. This period will see mostly normal temps, which will be chilly, but no dramatic cold snap. A strong low works out of the central plains toward the end that window and brings rain for the 13th and 14th. The system looks very moisture laden at this time and has the potential to bring up to 1.5” to 100% of the state. Cold air looks impressive behind the system, and likely allow for backside snow on the 16th.

So, well above normal precipitation is on the way for the start of 2019, and nearly all of it comes as rain. We should see plenty of water sitting around the state and have excessively moist soil profiles.
