Houston, brace yourselves for a rollercoaster weather pattern packing showers, thunderstorms, and potential major flooding. The National Weather Service (NWS) forecasts a 30 percent chance of storms today, mainly post-lunch, with a high near 83 degrees and blustery gusts up to 20 mph. Come nightfall, more scattered storms could stir before 10 pm, then again after 1 am, dragging night temps to a sultry 73 degrees, as reported by NWS Houston.

Tensions spike with the capricious skies as the area gears up for severe weather threats extending through the week. Thursday promises a 40 percent storm probability, with southeast winds hurtling at speeds of nearly 30 mph. And it doesn't end there. The NWS Storm Prediction Center flags a 'Marginal Risk' of severe thunderstorms reaching across from the upper Mississippi Valley southwestward to parts of northwest Texas, as weather warriors await the shortwave trough's deepening influence on Thursday, as per SPC.

As if the skies' onslaught wasn't enough, major flooding is already wreaking havoc or is on the imminent horizon in Houston. An urgent weather alert signals flooding in progress or set to hit hard late today around the East Fork of the San Jacinto River, impacting southeast Montgomery and northeast Harris counties. Officials advise locals to keep tabs on road conditions via @houstontranstar and to ring HCSO MAP at 713-CALL-MAP for roadside assistance during peak daylight hours, as noted by HCSO Texas X post.

As Friday approaches, there emerges chance for a brief meteorological respite, with a 30 percent likelihood of early showers before the afternoon and a partly sunny break in the clouds. But night brings back a familiar pattern of mostly cloudy skies and a 72-degree tether. The weekend forecast dangles the hope of partly sunny relief, but come Monday, temperatures are set to catapult near 90, signaling a brief affair with the sun before yet another turn of weather turmoil.
