Houston\u2019s\u00a0hottest stretch of August so far<\/a> could send temperatures to 100 degrees or higher on multiple days this week, but the most vulnerable records may come overnight rather than during the afternoon.<\/p>\n High pressure over Texas will keep Houston mostly dry through midweek as temperatures climb. Several days could reach the century mark, with little relief at night and only limited rain chances later this week.<\/p>\n Houston temperatures could reach 100 degrees several times this week<\/p>\n The core of a strong midlevel ridge \u2014 known as a “heat dome”<\/a>\u00a0\u2014\u00a0will remain over Southeast Texas through at least midweek, limiting cloud cover and shutting down most opportunities for rain. An additional pocket of relatively dry air arriving Wednesday and Thursday should make showers even harder to come by.<\/p>\n Article continues below this ad<\/p>\n That combination will allow afternoon temperatures to inch higher. Areas along and north of Interstate 10 will have the best chance of reaching 100 degrees early in the week, with some locations potentially topping out around 101. By midweek, more numerous 100-degree highs are expected to reach Southeast Texas.<\/p>\n CLIMATE CONNECTION: El Ni\u00f1o could reach record levels by next month. How close are we to a \u2018super El Ni\u00f1o\u2019?<\/a><\/p>\n Afternoon humidity will ease somewhat as dew points fall into the upper 60s and lower 70s, which could keep heat index values just shy of heat advisory criteria early this week. Even so, 100-degree heat will still be potentially dangerous for anyone spending hours outside.<\/p>\n Even after sunset, Houston won\u2019t cool off much. After Monday morning started in the low and mid-70s, lows for the rest of the week are expected to hover around 80 degrees, leaving homes, pavement and people with little time to shed the previous day\u2019s heat.<\/p>\n Article continues below this ad<\/p>\n Houston’s record highs are probably safe, but warm nights could challenge records<\/p>\n Triple-digit heat sounds record-worthy, but Houston\u2019s afternoon records this week are in another league. Every daily record high through\u00a0Aug. 23 exceeds 105 degrees, leaving forecast highs near 100 or 101 several degrees short.<\/p>\n The better chance for a record will come overnight.<\/p>\n
