First, I apologize for the lack of posts today. I had my first (and hopefully only) encounter with food poison yesterday evening and it’s taken most of the day to…

Nov 22
Highlights:
Before we discuss what lies ahead, let’s look back at yesterday’s snow event that “overachieved” for many. Particularly just northwest of the city where 2″-4″ fell. Snowfall rates were heavy enough to overcome the initially warm surface temperatures, and it was very impressive to see the way the snow accumulated considering this was a November event that took place from late morning into the early afternoon (when the sun angle does the majority of it’s work). This was an impressive first snow of the season and this morning’s snowpack is widespread throughout the Mid West.
The visible satellite this morning shows the snow cover across the central and northern portions of the state, where single digits and teens were common.
The next few days will feature dry and cold conditions. While we’ll remain below average, temperatures will slowly begin to moderate from the arctic intrusion of today.
We’ll get into a SW (milder air flow) regime for a brief period of time Thanksgiving Day out ahead of our next storm system that will move in Thanksgiving Night and Black Friday. Clouds will increase and moisture will spread into the region during the aforementioned time period. Most of the rain will fall Friday, so plan on taking the rain gear with you as you venture out to begin that Christmas shopping.
Much colder air will pour into the region Thanksgiving weekend and we’ll have to maintain a close eye on the evolution of things late next weekend into early December. Models will continue to waiver on specific solutions over the next few days, but there will be an attempt of a southern stream storm system coming out and “attacking” the cold air in place…

Highlights:
Our storm system is arriving on schedule this morning as rain is overspreading central IN. Just north of the city, snow flurries are falling as we type this (Boone County). Further north it’s mainly a snow event. Elsewhere, rain will continue to overspread the region before transitioning to snow from late morning into the early afternoon from northwest to southeast.

We think rain will transition to snow for Indianapolis, itself, just after lunch and may come down heavily for a time from early afternoon into the mid afternoon hours before tapering off as evening arrives. While it may be falling “fast and furious” for a time, warm surface temperatures will limit accumulations from what they would be otherwise. Here’s our updated snowfall map.
The big concern this evening will be flash freezing as a gusty NW flows travels over a fresh snowpack just to our north and helps temperatures plummet into the teens tonight. Wind chills in the single digits can be expected followed by highs tomorrow only in the 20s.
Moderation will occur as we move through Thanksgiving week before our next storm system arrives late Thanksgiving Day. Rain and breezy conditions will move in late Thursday into Friday before a much colder air mass oozes into the state late in the period. This may set the stage for a rather “interesting” open for December as a storm system tries to “attack” the cold…

Highlights:
Our big autumn storm system is swirling through the central Plains this morning. It’ll begin to pick up forward momentum and head northeast over the next 24 hours.
We’re dealing with an impressive fetch of moisture (w/ a Gulf of Mexico connection) this morning and that’ll help feed embedded heavy downpours this morning into the early afternoon. Here’s a time stamp of forecast radar images, courtesy of Weatherbell.com.
As mentioned above, with a GOM connection, embedded heavy rain will dampen your Wednesday activities. On average, we’ll add an additional half inch to inch of rain today (that’s on top of what we saw Monday and Tuesday).
Once to tomorrow all eyes will be on our next storm system that will eventually help pull down the season’s first blast of arctic air. Ahead of the cold surge, expect light rain to end as light snow across central IN Saturday. This won’t be a big deal from an accumulation perspective, but it’s always exciting seeing the first snow flakes of the season. Further north, across our northern tier of counties, a couple inches of snow will be possible.
We’re also keeping a close eye on Thanksgiving’s weather. While still a bit early to be specific, initial thoughts suggest we’re dealing with a storm on, or just on either side of Thanksgiving, that will provide rain to begin, but we caution that another surge of early season arctic air looks to pour in behind that storm system and potentially set the stage for a more impactful winter event to open December. More on that in the days ahead…
