...FINALLY A DAILY COLD RECORD AT LA CROSSE, WI...

ON SATURDAY, SEPTEMBER 7, THE LOW TEMPERATURE AT LA CROSSE REGIONAL
AIRPORT FELL TO 40F. THIS TIED THE RECORD LOW FOR THE DATE SET BACK
IN 1956 AND 1986. THIS WAS THE FIRST TIME THAT EITHER A DAILY COLD
HIGH OR RECORD LOW HAS BEEN SET OR TIED IN LA CROSSE SINCE FEBRUARY
15, 2021. THIS 1,300-DAY STRETCH IS THE LONGEST STRETCH OF DAYS
BETWEEN SIMILAR (DAILY COLD-TO-COLD OR WARM-TO-WARM RECORDS) DAILY
TEMPERATURE RECORDS. THE PREVIOUS RECORD WAS AN 818-DAY STRETCH FROM
JULY 7 THROUGH OCTOBER 3, 1999. LIKE THIS LATEST STRETCH, IT WAS
ALSO A STRETCH OF DAYS WITHOUT A DAILY COLD RECORD.

IF LOOK AT THE 10 LONGEST OF THESE STRETCHES, 9 OF THE THEM WERE
STRETCHES OF DAYS BETWEEN DAILY COLD-TO-COLD RECORDS AND JUST 1 OF
THEM WAS A STRETCH OF DAYS BETWEEN DAILY WARM-TO-WARM RECORDS (A 524-
DAY STRETCH FROM MAY 1, 1992 TO OCTOBER 7, 1993).

* SIMILAR TEMPERATURES REFERS COLD-TO-COLD OR WARM-TO-WARM DAILY
  TEMPERATURE RECORDS.

THROUGHOUT THE LA CROSSE CLIMATE DATABASE, THERE HAS BEEN A GRADUAL
INCREASE IN THE NUMBER OF DAYS BETWEEN DAILY TEMPERATURE RECORDS.
THIS IS TO BE EXPECTED, BECAUSE AS RECORD DATABASES LENGTHEN, THE
DAILY RECORDS BECOME INCREASING MORE DIFFICULT TO BREAK, SO THE
AVERAGE DATES BETWEEN THEM GRADUALLY LENGTHENS.  ONE THING
INTERESTING SINCE THE 1970S IS THAT THERE HAS BEEN A DRAMATIC
INCREASE IN THE NUMBER OF DAYS BETWEEN DAILY COLD-TO-COLD RECORDS.
THIS IS BECAUSE THE FREQUENCY OF COLD RECORDS HAVE BEEN DECREASING.
THIS IS NOT HAPPENING WITH EITHER THE WARM-TO-WARM RECORDS OR
BETWEEN ANY DAILY TEMPERATURE RECORDS.
