As of 5:40 a.m. CDT on Sunday, April 26, New Orleans’ Lakefront station (KNEW) was mostly cloudy with temperatures around 73°F and very high humidity. A muggy day is on tap, with scattered showers or isolated thunderstorms likely to bubble up late this morning and into the afternoon. Expect a daytime high near 85°F and sticky conditions if storms stay away.
Afternoon Storms Possible
Showers and a few thunderstorms will be most likely after about 9 a.m., with the greatest coverage through the midday hours and the afternoon commute. New rainfall amounts of roughly a quarter to a half inch are possible in spots that see storms, and brief heavy downpours could cut visibility and cause ponding on low-lying streets. According to the NWS forecast, the chance of precipitation this afternoon is near 30 percent.
Evening Commute And What To Bring
Tonight carries only a slight chance of leftover showers before about 7 p.m., then skies turn partly cloudy with lows near 70°F, and overnight temperatures may creep into the low 70s. If you have outdoor plans this afternoon or early evening, bring a quick-dry rain layer and build in a little extra travel time, since heavy rain can make roads slick and drop visibility fast. Local transit riders should be ready for changing conditions during peak hours.
Heat Returns By Monday
Monday, April 27, is forecast to be warmer and sunnier with highs near 87°F, and Tuesday, April 28, looks similarly hot with highs in the upper 80s. The National Weather Service's forecast discussion points to a warming trend into midweek, with heat index values potentially climbing into the upper 90s on the hottest days and an ongoing thunderstorm threat later in the week. See the NWS forecast discussion for more details.
Marine And Wind Notes
Coastal waters will stay under a south-southeast flow of about 10–15 knots through midweek with seas generally 1–3 feet. Any thunderstorms that move over the water can bring locally higher winds and choppier seas. By Friday night into Saturday there is some potential for gusts up to 30 mph, particularly near the coast, so secure loose outdoor gear if you have plans later in the week.
We will publish updates if any watches or warnings are issued. In the meantime, check radar and local alerts before heading out and be ready to adjust outdoor plans for heavy, brief downpours. If you work on the water, check marine forecasts before leaving the dock.
