Indiana Weather Outlook 12-28-16


Dry today over the state. Sunshine holds over the northern half, while clouds likely try and build in over the south. These clouds will thicken up as we watch a system get ready to pass by to the south of the OH River overnight tonight through tomorrow. This system does not look to have much of an impact here. In fact, the only areas where we need to keep an eye out for a few spits or sprinkles will be over the southeast corner of the state. Moisture there looks to be a few hundredths of an inch to perhaps a tenth…but nothing significant.

Dry weather is back for the remainder of tomorrow and most of Friday. However, we still look for increasing amounts of activity through the holiday weekend. Overnight Friday in to Saturday we can see some clouds over a large part of the state, but nothing more than a few widely scattered showers. Sunday we can see slightly more action but still, coverage no better than about 30-40%.

That should be enough to bring half to 1 inch rains to 100% of the state, with Monday (the 2nd) being very, very soggy. The map show a snapshot of action late Monday afternoon.

Behind the system, drier, colder weather emerges for the rest of the week. Temps move back to below normal levels and stay there into the weekend. We may have to keep an eye out for light snows overnight Thursday night into Friday but the little wave does not look overly strong at this point.

In the extended period, temps turn colder, with a big push of below normal air in over the state. In fact, we can see temps go back to near zero in the extended window and stay there for a longer period of time. We also have the potential for another strong system to sweep through around the 9th and 10th, but models have some significant disagreement on strength out that far. Stay tuned.
