Indiana Weather Outlook 3-8-18

Cold air continues its dominance today and tomorrow over the region, but we do see a move toward a drier pattern. In fact, we make it from today through all of next week with very little threat of precipitation. Today and tomorrow high pressure will be working across Indiana. Clouds will still be a part of the forecast today, but less of a part, and full sunshine is in tomorrow. Over the weekend, we transition onto the backside of high pressure, and that will bring some south and southeast flow, allowing temps to moderate just a bit. We have no threat of precipitation through Sunday. On Saturday we could see some clouds into southern Indiana, an off shoot of a storm complex that stays south of the Ohio River this weekend.

On Monday, we see warming continue with good south wind flow. However, we have a few more clouds that come in as the warm air arrives. This may allow for a few spits and sprinkles overnight Monday night into the first part of Tuesday, but at this time, this looks highly disorganized, and likely is not going to be an issue. That is why we are keeping our forecast dry, in terms of actual precipitation. That dryness goes through the end of the week, right through Saturday. We will see a significant change in air mass, though, going into Wednesday and Thursday. Winds shift back to the northwest, and we will see cooler temps in that period. The low tracks across the great lakes, and we should be able to see good sun through the end of the week, in spite of the cool down.

The extended forecast pattern suggests we still see our next good front late on the 17th into the 18th, with rains of .2”-.6” over the state. The best coverage looks to be over the southern half of the state. We follow that up with dry weather for a good 3 days, and then another low moves in around the 22nd, bringing rains of .1”-.5” and coverage a little better at 80%. Still, the dry pattern for the next week to 10 days means we will be ready and likely willing to accept some moisture out of those extended period systems.
