Trending Colder Late In The Period…

screen-shot-2016-11-05-at-9-24-45-amHighlights:

  • Frosty start
  • Pleasant fall weather
  • Light scattered shower Tuesday evening

Lots Of Sunshine…Most folks around central IN woke up to the most widespread frost of the season so far.  Many neighborhoods away from the city slipped into the middle 30s overnight.  (It’s about time)!

High pressure will supply dry conditions through the weekend and into early next week.  With crisp, dry air in place, it’ll feel mighty nice outside.  Given what will likely be an increasingly “busy” (and cooler) second half of November, we’d recommend spending as much time outdoors as possible this week.

A weak frontal boundary will pass through central IN Tuesday night.  Though the air mass will be very dry in front of this system, we can’t completely rule out the chance of a light shower Tuesday evening as the front moves through.  (This won’t be a big deal).

Reinforcing chilly air will blow into town to wrap up the work week and early indications hint at the first freeze for many by next weekend.

Wednesday Evening Rambles…

A rainy and (at times) stormy night is ahead for central Indiana as a cold front approaches.


While scattered thunderstorms are impacting portions of central IN as we type this (6p and looking at you Whitestown), more widespread showers and embedded thunderstorms will blow into town late tonight. Here’s an idea of what the radar may look like around 10p.


For most neighborhoods, expect 0.25″-0.50″ of needed rain tonight into the wee morning hours Thursday. There will be localized heavier totals through central Indiana.


Temperatures will be cooler Thursday, but will remain above normal- generally topping out in the middle and upper 60s in the afternoon before falling Thursday evening. Cooler air will be with us to close the work week (upper 50s to around 60° for most for highs Friday).


Our next storm system has it’s eyes on the area Tuesday evening into Wednesday, but looks less significant when compared to 24-48 hours ago. We’ll continue to keep an eye on things.

GFS ensemble members aren’t terribly “excited” about our next storm potential next week.


There continues to be a great deal of interest around colder times and a pattern change around mid-month. We want to reiterate a couple things:

1.) Wholesale significant pattern changes can (and normally do) wreck havoc on medium and long range data. To our fellow weather friends out there who love to look at run-to-run operational data, expect wild swings as the pattern transition gets underway mid month.

2.) While we’re fully in the camp of a major reversal to cold, we caution the initial pattern transition will likely feature a “step-down” process before shifting to more of a true winter-like pattern (likely complete with plenty of storminess; hello snow lovers) from the Thanksgiving to Christmas period.

One More Warm Day; T-storm Chances Tonight…

screen-shot-2016-11-02-at-7-35-00-amThe 2016-2017 IndyWx.com Winter Outlook is now available.

Highlights:

  • Unseasonably warm Wednesday
  • T-storms tonight
  • Cooler close to the work week

Cold Front Arrives Late Tonight…The majority of today will be dry (and warm), but we do note some of the high resolution model data suggest we deal with an initial round of scattered showers and thunderstorms this evening (in the 4p-7p time frame).  This would be in advance of more widespread showers and thunderstorms tonight into the wee morning hours Thursday.

Cooler air will flow into the region to wrap up the work week and dry conditions will prevail through the upcoming weekend.  We note patchy frost potential Saturday morning away from the city.

Our next storm system will approach early next week.  From this distance, Election Day looks mostly dry through the daytime hours,  but shower chances will begin to increase by evening.

Longer term, model data continues to suggest we’re in line for a mid-month pattern change to cooler conditions.  While this will initially be a “step-down” (back and forth) process, the potential is on the table for a downright wintry pattern to develop by late month.  We note the GEFS (GFS ensembles) keying in on this (images courtesy of weatherbell):
