APR 2023 ENDED TIED WITH 2017 FOR THE WARMEST APRIL ON RECORD. IT WAS ALSO
VERY DRY FOR MUCH OF THE MONTH. THE FIRST THREE WEEKS OF THE MONTH
WERE EXCEPTIONALLY DRY WITH MOST OF THE RAINFALL FALLING THE LAST THREE DAYS
OF THE MONTH. A PERSISTENT UPPER LEVEL RIDGE WAS THE CULPRIT FOR THE VERY AND
DRY CONDITIONS.
