TUCSON, Ariz. - Tucson has experienced the coolest May so far in more than 40 years, according to the National Weather Service.
The last time the Old Pueblo had such a cool month of May was back in 1977.
Has May felt cooler this year than it has in the past in #Tucson? That’s because (so far) it has been! #ComingUp on @kgun9 why we’ve seen cooler temps & how it’ll impact us in the months to come. pic.twitter.com/XeVFvIohGB— Veronica Acosta (@VeronicacostaTV) May 21, 2019
Meteorologists with the National Weather Service said the average high during this time of the year is around 93 degrees, but what was felt on May 20 was much different.
"Given this cold pattern we are well below normal, about 20 to 25 degrees below normal for this time of year," said Glenn Lader with the National Weather Service.
The unusual cooler weather is coming from systems near the Pacific, according to Lader.
"Normally we don't see weather systems moving this far south and this cold this late in the season so it's quite unusual," said Lader.
While it's nice for the moment, Lader added we can expect temperatures to creep back up starting today.
