If you were thinking the past month was hot and dry, you would certainly be correct. Thornton’s July saw average mercury readings a good bit above average and precipitation well below average.
Looking back, probably one of the most notable things about the month was that there wasn’t a whole lot notable. We saw nothing significant in the way of severe weather and while it was hot, it wasn’t overly extreme. It was noteworthy that the last two weeks of the month were quite dry yielding only 0.03” of rain over the period.
