Wet Today; Colder Air Coming…

  • Rain today
  • Breezy and turning cooler
  • Secondary push of early season arctic air

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.

3pSimRadarAs 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).

RaintotalsOnce 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.

SatPMStormTrackWe’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…
