80s Stretch Comes to An End…………..Blackberry Winter or Locust Winter

May 23rd, 2013 at 12:39 pm by under Chad's WLFI Weather Blog

Our 8-day stretch of 80s came to an end yesterday with a high of 75.  Today’s 63 occurred at midnight with a morning-afternoon high of 61.  Lake front has dropped temperature from 61 to 53 quickly.

Our stretch of 80s in May was the longest since a 10-day stretch (May 22-31) in 2010 at West Lafayette.  Before that, 1998 had a similar, long, stretch with 8 consecutive days of 80s.


Spotty showers, chilly north winds & slowly-falling temperatures into the 50s area-wide will dominate today with mostly cloudy to cloudy skies.

Clearing will occur evening-tonight.  As “Blackberry Winter” & “Locust Winter” roll on, lows will drop to 38-41 area-wide.  Blackberry Winter is a period of cool weather where we see our last 40-45 temperature in late May to perhaps early June as the blackberries are in blossom.  Also referred to as Locust Winter, it is the last cool snap until September & often coincides with the last of the Black Locust trees.

Black Locust:




It appears that no frost will be able to form in Jasper, Newton & Pulaski counties (where temperatures will be at 38) due to a high likelihood of a north breeze.

Regardless, it will be cold!

Tomorrow looks good with mostly sunny skies & 65-68 area-wide.  High & mid clouds will increase tomorrow night as warm front approaches, with lows in the 40s.

    I saw the temps forecasted for tonight and then saw the wind – thankful for the wind – or else I would be dealing with covering tomatoes and peppers to protect them.
