Houston woke up Sunday to a steamy, low-visibility start, with patchy fog trimming visibility on local roads and temperatures in the mid-70s. Forecasters expect the fog to hang around into mid-morning before the sun breaks through and drives highs into the upper 80s, near 87°F, this afternoon. Light to moderate southeast winds will keep the air feeling sticky for Mother's Day plans, and the main weather punch for the metro is still expected to arrive after sunset when storms roll in.
Afternoon: Warm, Sticky, Mostly Sunny
Patchy fog should clear by mid-morning and give way to mostly sunny skies, with highs around 87°F and southeast winds of 5 to 10 mph. The combination of warmth and humidity will make outdoor plans feel muggy, so bringing water and finding shade is a smart move if you will be outside this afternoon.
Tonight: Strong To Severe Storms Possible
A line of strong to potentially severe thunderstorms is expected to slide south from Central Texas this evening and into the overnight hours. The main band is forecast to reach the I-10 corridor before midnight and the coastline late overnight, with isolated severe storms possibly developing ahead of that line and posing threats of damaging winds and large hail. Showers and thunderstorms become more likely after about 10 p.m. and continue into the overnight, with overall precipitation chances around 60 percent and new rainfall amounts of a tenth to a quarter of an inch possible. No active watches or warnings were in effect at the time of the latest forecast, but that could change as storms organize and move eastward overnight, so residents are urged to keep an eye on updates, according to the NWS.
Commute, Coastal And Event Impacts
Morning patchy fog may slow the early commute, and this evening's storms could bring sudden downpours and damaging gusts that make driving hazardous, especially along the I-10 corridor and toward Galveston Bay. Marine interests should watch for a line of offshore storms capable of producing strong downdraft winds, although forecasters did not expect Small Craft Advisories at the time of the discussion. A rising storm risk was flagged earlier in the week; see the rising storm risk earlier in the week for background.
What To Do
If you have outdoor plans tonight, consider moving them earlier or indoors and keep a simple weather app or local radio handy for any warnings. If storms become severe, seek sturdy shelter away from windows and avoid driving through flooded streets.
