Heat advisory for this weekend

Posted

The first few weeks of August are typically the hottest parts of the year across southeast Texas and 2019 will be no different.
A strong upper-level ridge of high pressure over the southwest US will drift eastward and become centered over Texas and the southern plains by the end of this week into next week. Strong subsidence or sinking air under this high-pressure ridge will result in limited clouds and rainfall and increasing surface temperatures.
Expect highs to rise into the mid to upper 90’s by late this week and this weekend and then into the upper 90’s and low 100’s by late this weekend into early next week. Southerly winds will remain in place through the period allowing humidity levels to remain high and resulting in afternoon heat index values of 105 to 110 degrees. Heat advisories may be required if large portions of the area experience heat index values above 108 degrees.
Overnight lows will average around 80 degrees with lower 80’s along the coast. Extended range forecast models show little change in the position of the southern plains high-pressure ridge well into next week, so very warm temperatures are expected into at least the middle of next week.

Heat-related deaths are preventable. Protect yourself and others from the impacts of heat utilizing the following:

* Stay hydrated and take frequent breaks in the shade or air conditioning

* Limit strenuous outdoor activities and try to complete such activities early in the morning or in the evening

* Check up on the elderly, those with health issues, and anyone without AC

* Never leave kids or pets unattended in a vehicle…Look before you Lock.
