| Record March Warmth - Summary |
After a "winter" of much warmer than normal
temperatures, the month of March upped the ante - resembling early
summer more than spring for the area. A string of days where the high
temperatures reached well into the 70s to middle
80s dominated the middle portions of the month, and some
longstanding records fell along the way. Low temperatures on some
mornings failed to drop below 60 - rare for March in the Ohio
Valley. Below is a graphical and tabular summary of what was an
incredibly warm month.
Record Daily Temperatures Set Across OH/KY/IN in March
2012
Below is a table of the number of records (both record high maximum
temperatures and record high minimum temperatures) set across all of Ohio, Indiana, and Kentucky
during the month of March.
It was a much more prolific month for record high maximum
temperatures than record high minimums. What is also
impressive to note is, the average difference for each record
broken during the month. While some records were only tied or
marginally broken, the average difference for the entire month exceeded
4 degrees per record, indicating that as a whole, daily records were
bested easily in most instances.
As the table below clearly shows, the most atypical days for widespread
warmth (via number of records broken and amount those records were
broken by) were March 20th, and March 21st.
