Dry Triple Digits May Be Ending

The disaster proclamation covers 167 Texas counties, including Harris and the surrounding counties. It not only paves the way for federal assistance, but also allows the state to move quickly to respond to changing conditions.
The many days of triple digit temperatures and extremely dry conditions are due to a high pressure system that's parked over Texas.
"What happens underneath these areas of high pressure, at this time of year, is just a lot of hot air builds up. The high pressure suppresses any attempt at precipitation."
And says AccuWeather meteorologist John Gresiak, a steamy oppressive drought kicks in that's yielded only an inch and quarter of rain since the beginning of June. We usually get about seven inches.
The end of this dry weather cycle comes when the high pressure system leaves the area.
"Well, it's already starting move right now. In fact the high is shifting westward into New Mexico and Arizona."
Gresiak says that will allow cooler air to dip down from the middle of the country and will be responsible for the less hot and wetter weather this week-end and into next week.
