Weekly Outlook: Cool Start, Mild Finish

A secondary cold front is moving into central Indiana this afternoon with clouds, gusty northerly breezes, and fresh cool air. Speaking of cool, September, so far, has been cooler and…

Catching Up On A Tuesday Evening…

Several interesting weather items are on the docket and each will have to be dealt with as they come over the course of the upcoming 7 days.  Some of the headlines include a brief warm-up Saturday, weekend rain that could include a tropical connection Sunday, and another big shot of October-like chill next week.

While we have a few more days of below normal temperatures in front of us, we eye at least one day where temperatures will manage to climb above normal and that’s Saturday.  All indications still suggest we’ll be very close, if not a degree or two higher, than the 80 degree mark along with a nice southwest air flow in place Saturday.  All-in-all, it’ll be a great day to take care of any early-autumn yard work that’s needing to get done.

Changes brew Sunday as a cold front draws near.  This is where questions lie and they actually have to do with Tropical Storm Odile (currently all the way to our southwest over the central Baja California peninsula region).  Odilemoisture

While the GFS and European forecast models still aren’t interested in “welcoming” Odile’s moisture into the region, we note the Canadian model does suggest some tropical moisture, courtesy of Odile, gets entangled along the front Sunday.  We’ll continue to keep a close eye on things and monitor the forecast data accordingly moving forward through the back half of the work week.

 

The other item of interest has to do with yet another big blast of autumn air that will have things feeling very much like October around these parts come early next week.  The above average temperatures Saturday will hang around just for the day as yet another unseasonably chilly air mass moves into the area Monday into Tuesday of next week as a significant trough develops over the east with an impressive western ridge in place.  f156

 

Note the GEFS and Canadian show the return of the unseasonable chill next week.  Keep those jackets handy.  Early indications would suggest this type air mass is plenty capable of highs in the upper 50s/ lower 60s and overnight lows in the upper 30s/ lower 40s during the height of the chill (most likely Tuesday).  Stay tuned…

Watching Storms To Our Northwest This Morning…Today is a bit of a tricky forecast.  A complex of showers and thunderstorms is tracking through northern Illinois this morning and we’ll monitor this area of showers and storms in the event it begins to shift south of a due east track.  Additionally, outflow boundaries from this complex may trigger additional development of showers and thunderstorms later today.  Best rain/ storm chances should remain across northern Indiana, but we’ll keep an eye on things.  With all of that said, we think most folks here across central Indiana will remain rain-free, including lots of sunshine today.

Cold Front Ushers In A Much Cooler Weekend…A cold front will move through the region early Saturday morning. Ahead of this boundary, a broken line of strong to severe thunderstorms will likely blow through central Indiana Friday night.  We continue to fine tune timing, but thinking at this point highlights 8p to 1a Friday night and Saturday morning (we’ll “tighten” that time line up later tonight).

A few left over showers are possible into Saturday along with a MUCH cooler, fall-like, feel that will continue into next week!

Big Blast Of Cool Air Mid Month…Good model agreement remains on a big blast of cool air blowing in later next week.  Once again, rain and storms will remain in the forecast as the strong cold front blows through.  Behind the boundary, some truly chilly air would arrive… More details to come as we move forward, but it may be a good idea to go ahead and pull those jackets and sweaters out if you haven’t already.

7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast: 0.50″ – 1.00″
  • 7-Day Snowfall Forecast: 0.00″
GEFS temperature anomalies over the next two weeks show the 1-2 punch of cool air coming. Time to think about pulling out those jackets!
