Clouds and moisture will be over the state today, ending toward midday in northern Indiana, if not sooner. An additional few hundredths to a tenth or so can fall this morning in the north. We may see a lull farther south, but generally, moisture wants to continue to sit across southern Indiana into this evening and the overnight. A stronger surge of moisture comes tomorrow from SR 28 southward. This will bring at least an additional .25”-2” through tomorrow, and there can be some areas that get a little more, combined. Most of the northern third of the state will be dry from this afternoon through tomorrow. The map above shows moisture through Sunday morning.
High pressure comes in for Sunday and will give us a quick move back to dry weather. That dry pattern holds through next Wednesday. A second high pressure center moves across the state toward Monday afternoon-Tuesday. Temps will fall off Sunday and Monday, but not by too much, and then we climb again, and should be near normal through a good chunk of the week.
Moisture is back for the second half of next week, as scattered showers arrive Thursday morning. At this time, we are expecting a few hundredths to .4” rain potential with coverage at 80% of the state. This will be a relatively light rain event. All action does look to be out of here by Thursday night near midnight. Much colder air starts to funnel in behind the system, and we go dry for that Friday and the following weekend. At this point we look for air to be cold enough for snow for that weekend ahead of Christmas, but we actually do not see any significant snow chances.
The extended period remains dry through the 26th. Cold air dominates through that period. We look for south winds to start to develop on the 27th ahead of our next system, which arrives late the 27th into the 28th. This will moisture of .25”-.75” liquid equivalent, but right now we are going to allow for either rain or snow.
