Tomorrow is still looking hot, but not as hot as today, and we may even see an isolated shower or storm near the coast. #HOUwx pic.twitter.com/UmsVsCMmSa
Despite the continued scorch, there's a 20 percent chance of rain that may offer a brief reprieve with showers and thunderstorms forecasted to potentially develop after 1 pm today, as per the detailed forecast for the region obtained from The National Weather Service. The rest of the week appears to cleverly follow suit, with mostly sunny days accompanied by intermittent chances of precipitation and similarly sweltering highs in the mid-90s.
Tonight, Houston can expect a mostly clear sky with a low of around 80 degrees. But the nighttime respite will not last long as the mercury is set to climb back up come Friday. The region is looking forward to another balmy night with southeast winds gently turning south after midnight.
Concerns over severe weather have also been raised by the NWS Storm Prediction Center, noting a marginal risk of severe thunderstorms sweeping parts from the central High Plains to the western edges of Minnesota and even northern Arizona into parts of Utah, according to their latest forecast discussion. Localized severe gusts and hail could become emergent threats as conditions are projected to steadily intensify by late afternoon into the evening.
In part of Texas, the threat seems to concentrate on high-based convection due to strong heating and mixing in the vicinity of a weak surface trough and dryline. Yet, with large-scale ascent and shearing forces deemed weak, any storms in the Houston area are expected to remain mostly disorganized, potentially causing isolated downburst winds during the hotter part of the day.
Houstonians are advised to stay vigilant and prepared and check local forecasts for updates.
