Dry weather is here for the coming week. However, this period will not be without some drama, mostly thanks to temperatures. We look to be on the proverbial roller coaster this week. Cold air blasted into the state yesterday behind our very wet Saturday system. That cold air remains this morning, but we start to see a shift in winds later this afternoon. Those winds go southwest and increase toward sunset. We can be rather breezy this afternoon through tomorrow, and the strong southwest flow will take temps to above normal levels tomorrow. Sunshine should dominate through tomorrow, although with a potential rapid rise, we could see fog in spots tomorrow morning.
A cold front moves through tomorrow night into early Wednesday. We do not think there is any threat of major precipitation with this front in Indiana, but we probably do see some clouds overnight tomorrow night and for the start of the day Wednesday. The bigger story will be a dramatic fall off in temps again, with Wednesday and Thanksgiving Day Thursday ending up below normal. Winds shift back to the NW, aiding the cooldown.
The roller coaster decides to go back uphill from late Thursday night through the rest of the week and weekend. Temperatures climb for Friday with strong southwest winds returning to the region. We should see above normal highs for Friday and Saturday statewide. Again, we go through these temp changes with no precipitation. That means we see dry weather for the coming the coming 6 days including today.
A front still looks to move in for this coming Sunday. However, moisture availability does not look to be as impressive this morning. In fact, this front on Sunday may end up looking more like our front for tomorrow night – a wind shift bringing colder air, but not much else. For now, we will leave a chance for minor spits and sprinkles, but want Mother Nature to prove there is more to the system before going more than that. Either way, we go colder again for the finish of the weekend and start of next week.
The next good threat of precipitation develops at midweek next week. On Wednesday, the 29th, we see nice moisture moving in from the west. Temps are going to be near normal and should be warm enough to bring mostly rain. We may see a bit of wet snow early in the morning in north central and northeast Indiana if moisture arrives while we are still near our morning lows. However, we really are looking for .2”-.6” of rain over 80% of the state. This front should move through relatively quickly.
For the extended 11-16 day forecast window, we have a strong storm complex still on the way for early December…looking for arrival late the 1st and lingering through the 3rd. This system has moisture potential of .25”-.1” with coverage at 100% of the state. Warm air should be in for most of the event, but we won’t rule out action ending as wet snow, because cold air looks formidable on the backside of the front. We follow that with a dry upper-level high-pressure dome holding over the state through the 6th, keeping cold air in over the region.
