On the last few days of August the late summer heat increased,
and when early September arrived the record breaking heat
just got hotter. The old subtropical high that has been
so strong over Central and South Central Texas since late
June of 2000 has continued into early September.
Dry soils and abundant sunshine also helped temperatures
rise. Usually record breaking hot temperatures of
this magnitude, since the late 19th century, occurred
in June, July and August, not September.
On the other hand, some of the hotter days of record
have come just 2 to 3 weeks before early September.
At any rate the blazing heat of early September 2000
is definitely one for the record books.
