Thanks for posting that. It gives a good visual of the trends over time.

It also reminds me that we're due for a clunker.

LOT has seven consecutive days in the 90s starting tomorrow. We’ll see if that pans out, but am concerned about convective activity getting in the way later in the week.

25th anniversary of a record low of 49 on July 2, 2001.

That is the last time a daily record low minimum was set in July. Every other month has set a daily record low minimum since then, but that was the most recent one in July. (October’s most recent was also set in 2001).
