All I know is my grass is patchy brown. And thats with some pretty cool temps we've had for this time of year. That shouldn't happen in May.
I haven't checked the daily numbers, but I'm confident I did not receive 1" of rain for May. And my memory is that we've been below normal for several months prior. We had the last of our high QPF events in December. Since that time, it certainly feels we entered a new, dry regime.
*ETA
I just checked the records.....I missed 1.3" that fell on 5/3, so I was wrong about May's total. But, since that time I've had just 1"
And confirmed that I'm below normal every month since December, although April was just a little below normal.
