After this month’s blazing start with highs in the upper 90s and lows near 80º, August has taken on a much more temperate nature. Daytime highs have fluctuated between the upper 70s and upper 80s with overnight lows mostly in the 50s and 60s.
Despite the fact that the city has not experienced a 90º day in nearly three weeks, and Monday’s 55º low was the chilliest since July 7, August 2006—with a current average temperature running at 75.2º—still ranks as this city’s 27th warmest of the 136 on record since 1871.
Readings the rest of the week should cluster in the 80s, possibly reaching 90º on Friday.
An isolated shower may accompany Tuesday’s frontal passage, but the city’s best threat for additional rain is from late Wednesday into Saturday. Dew points will be on the rise during this period and the increased moisture levels will aid thunderstorm development as a series of fronts pass the area.
