I was taken aback when I discovered this astonishing fact about August 2010 so far: it could be the hottest in Houston history.  Not only has it been over 95° every day this month, we've also had some mornings where the low didn't get below 80°.  So when you compute the average for the month, you find that we're running at 88.3°, nearly a degree above the all-time hottest August from 1962 (87.5°).  A "normal" August would see an average temperature of 83.3°.  Thursday, we'll see our 13th heat advisory for the month.

As expected, a few storms developed in the late afternoon, bringing some scattered relief to folks north of Grimes, Montgomery and San Jacinto counties.  However, that rain fell just short of making their way into metro Houston, no match for the intense August heat.  In fact, despite a few isolated storms around Southeast Texas this month, only .32" has fallen in the rain gage at Bush Airport, making this the 3rd driest August on record.  Ironically, July was the 4th wettest.

Our best hope for rain tomorrow is that the sun will heat the "left-overs" from today's dying storms activating the moisture in the air and developing new storms.  Even though that is a likely scenario, it will get plenty hot and the heat index will remain over 105°, which is the criteria for maintaining the heat advisory.  After tomorrow, rain chances diminish, but the heat remains and so likely will the heat advisory - well into next week!
