Indiana Weather Outlook 12-19-17

No change in the outlook today. We still look pretty good for the next few days. We dry out, stay above normal for temps, and see better sunshine chances through Thursday. Winds go west at a moderate clip today, and stay like that through Thursday as well

Friday, winds turn more southwest, and clouds move in. Friday itself we do not see an exceptional amount of precipitation – only a few hundredths to a tenth or two over about 40% of the state. But, that action ramps up overnight Friday night through Saturday morning, where we see rains of .25”-.75” over 90% of the state. There still a threat of thunderstorm action down near the river, but we think the heaviest rains stay south into Kentucky.

For the rest of Saturday and most of Sunday we dry back down, but we see much colder air starting to push in from the NW. Precipitation continues to flow up the old, slowing, stalling frontal boundary over KY and areas south, but at this point, we do not expect any of it to get into the state. Sunday is very cold in the north, but only slightly below normal in the south. Christmas day continues to be the wild card. Moisture tries to work into the state into the cold air, but for right now, it looks fairly limited. We will look for scattered snow showers over about 50% of the state, enough to make it look like Christmas, but for now, we are tentatively going to call a close miss on the potential of a stronger Christmas storm. There is time for the track to adjust farther north, but for now, we are looking at an OK Christmas. The bigger story will be the brutal cold for next week. From Tuesday right on through the end of the week, temps will be well below normal, and will be the coldest of the season to this point.

In the extended period, we see another strong storm circulation developing in the southern plains for the New Year’s weekend. Current track is far south, but we continue to watch this one for an adjusting track that may start off 2018 with a significant winter event. Stay tuned!
