Temps remain below normal today but will be a bit warmer than where we started the weekend on Saturday. Clouds will be building today ahead of our next round of moisture. Precipitation is spreading up from the southwest, coming across MO and southern IL today. This evening we will start to see light precipitation push into Indiana, and it will continue overnight through tomorrow morning. Temps will be cold enough in many areas to see at least some wet snow, and from I-70 northward, we likely see all snow. Liquid equivalent precipitation totals will be from a few hundredths to .3”, but the upper end of that range will be limited to areas near the Ohio river from midnight tonight into tomorrow morning. Those are also the areas that are most likely to see rain mixing in or even trying to dominate most of the event. The heaviest moisture will stay south of the Ohio River and track across KY and WV.
We see clouds tough to break the rest of tomorrow but should see sunshine for all of Wednesday. Temps remain normal to a bit below normal.
On Thursday, we have another strong low passing by to our south, working through the Tennessee valley. This will eventually turn into a rather strong east coast storm and may even develop into a “nor’easter”. But, as it passes south of us on Thursday, we do see some moisture trying to build north. Thursday afternoon it makes it into far southern Indiana, staying mostly south of US 50. Thursday evening that moisture bubbles a little farther south to near the SR 28 corridor. And then closer to midnight we can even see it pushing farther into northeast Indiana, as the entire low continues to drag east. Temperatures Thursday afternoon will be between 36 and 42 degrees over most of southern Indiana. So, while we see some moisture, it likely is more liquid than snow. As the sun sets and the moisture pushes north, we have to watch for wet snow and rain mixing in. Light snow and flurries can be seen as the main precipitation type toward midnight. Liquid equivalent precipitation totals will be anywhere from a few hundredths to .4”, but the higher totals will be from US 50 southward. Other mentioned areas will be closer to a tenth or less, and we see nothing in west central, NW and north central parts of the state. The map above shows precipitation for the week, combining the minor moisture from tonight/tomorrow with the Thursday-Friday event.
Dry Friday statewide. Then Saturday, a little clipper like disturbance shoots out of the upper Midwest and moves across northern IL, northern IN and southern MI. We can see a few hundreds to .3” of liquid equivalent precipitation, but it likely all comes in the form of wet snow, meaning we could see a fresh coating. Temps Saturday will be in the mid to upper 30s though, so this likely is not a big deal. We stay dry from SR 26 southward.
High pressure takes over the entire state Sunday, and we stay dry through next Wednesday.
In the extended period, we are going a little drier now. Thanksgiving should be dry, but we see 1 system for the 11-16 day window, moving through for the 24th and 25th. Rain totals can be from half to 1” and yes, we are talking rain at this time. WE see good south winds developing next Wednesday into Thursday right at the end of the 10-day period. This will bring a warmer flow pattern in and allow us to see temps about 5-7 degrees above normal. That promoted the late November rain.
