Big Changes Loom…

screen-shot-2016-11-15-at-7-47-52-amHighlights:

  • Mostly sunny and pleasant into mid week
  • Gusty SW winds usher in near-record warmth to close the work week
  • Friday night showers and storms
  • Coldest air and first flakes of the season ahead

Brace For Changes…The short-term remains very quiet and pleasant.  If you haven’t already, we suggest knocking out that remaining yard work for the season, or get a jump on the outdoor Christmas lights!  (Rude changes loom).

Winds will turn gusty out of the southwest Thursday, especially by afternoon.  These strong and gusty SW winds will top 40 MPH Thursday into Friday, but also serve to help give temperatures a boost.  Highs both Thursday and Friday will be near record levels.

We should remain dry through the daytime Friday, but a band of showers and embedded thunder will rumble through the state Friday night as a strong cold front passes through.  Behind the cold front, expect an abrupt wind shift to the northwest and falling temperatures through the day Saturday.  Heavier jackets and coats will be required as wind chills in the 20s fall into the teens Saturday night into Sunday morning.  Left-over, “backlash” moisture will fall in the form of flurries and scattered light snow showers.  Further north, light accumulations of snow are possible across northern IN snowbelt communities.

Cold, dry weather will continue into early next week.  Looking further ahead, another storm system looms around Thanksgiving.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.25″-0.50″

Taste Of Winter This Weekend…

A rather pleasant, benign week of weather will transition to a rude feel by the weekend.

A cold front will sweep through the state Saturday morning and will help the season’s first blast of true, winter-like air plunge southward over the weekend, into early next week.  Ahead of the cold front, a band of showers and perhaps a clap of thunder will track east.  As of now, rainfall totals don’t look particularly impressive (0.10″-0.25″).

Ahead of the front, winds will gust out of the southwest Thursday afternoon and Friday (in the 30-40 MPH range), but will shift around to the northwest Saturday (same 30-40 MPH potential) and drive a much colder air mass southeast.  Temperatures will fall through the day Saturday and temperatures will grow cold enough Saturday evening into Sunday to allow “backlash” moisture to fall as scattered snow showers and snow flurries.  Further north, in the snowbelt regions, heavier lake-generated snow bands and squalls will develop over the second half of the weekend.

Wind chills will fall into the teens Sunday night into Monday morning.

Longer term, data continues to suggest we continue to transition, overall, towards a colder and stormy pattern in the targeted Thanksgiving to Christmas period.  More on that later this week…

Frosty Mornings; Late Week Storm System…

screen-shot-2016-11-13-at-10-19-07-amHighlights:

  • Dry stretch of weather remains
  • Late week storm system offers up rain; t-storm chances
  • Much colder next weekend

Frosty Mornings To Start The Week…High pressure will dominate our weather pattern to open the new week.  As such, skies will remain mostly sunny and temperatures will be very pleasant.  Monday morning will feature the third morning in a row with sub-freezing air.  Expect another frosty start to the day, including outlying neighborhoods into the 20s yet again.

Looking ahead, our weather will remain rather uneventful until Thursday.  Dry conditions will remain, but southwest winds will become increasingly gusty by the afternoon.  This is in advance of an approaching storm system that will deliver showers, and perhaps a clap of thunder, Friday evening.  Timing will have to be fine tuned as we progress through the week.  Behind the boundary, much colder air will pour into the region on gusty northwest winds next weekend.  In fact, the air will grow cold enough to potentially lead to scattered snow showers Saturday night into Sunday in the left over “back lash” moisture.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.25″ – 0.50″

Chilly Weekend Ahead…

screen-shot-2016-11-11-at-6-58-12-amHighlights:

  • Dry and chilly weekend
  • First freeze of the season
  • Dry skies remain next week

Cold Air Blows In This Evening…We’ll wrap up the work week with plentiful sunshine, but reinforcing cold air will blow into town this evening.  After a high in the middle 50s, temperatures will begin to fall rather quickly by late afternoon into the early evening. Temperatures will grow cold enough to allow the first freeze of the season to greet many Hoosiers Saturday and Sunday mornings (many neighborhoods away from the city will drop into the middle/ upper 20s).

Dry skies will remain next week, but by the middle parts of next week, all eyes will be on our next fall storm system.  It’s still early, but the next best chances of rain appear to be slated for a late week arrival next week.  Colder air will follow.

Upcoming 7-Day Precipitation Forecast:

Snowfall: 0.00″

Rainfall: 0.00″
