The Storm Prediction Center (SPC) has continued a slight risk of severe weather for our entire county warning area today through tonight, meaning scattered strong to severe thunderstorms are possible across all of deep south Texas and the Rio Grande Valley prior to and during the passage of a cold front. Potential threats include damaging winds, large hail, isolated tornadoes, moderate to heavy rain and frequent cloud to ground lightning. Potential impacts of severe weather include fence, tree, roof and home damage. Low lying areas or poorly draining areas may be at risk for flooding from any heavier downpours. To be prepared for severe weather: make sure trees are trimmed of dead branches, fences are secured, tie down lightweight objects, move vehicles into garages or carports, check the batteries and set your NOAA Weather Radio into the “Alert” mode. Additionally, make sure your family, co-workers and students know where their “safe place” is located (and the plan to get there!), if a warning is issued.
Showers and strong to severe thunderstorms are possible today through tonight with high temperatures into the 90s. Severe thunderstorms may contain frequent lightning, large hail, heavy rain, and isolated tornadoes. Make sure your NOAA Weather Radio has working batteries and is set to “alert” mode. Additionally, remind your family, co- workers and students where the closest safe place is and the plan to get there in the event of a severe weather warning.
A moderate risk for rip currents is expected today along area beaches for continued elevated swell coming off the gulf. Remember to swim near a lifeguard if possible or use a non-inflatable flotation device, such as a life jacket or boogie board. Mostly cloudy skies can be expected today with scattered showers and thunderstorms, especially this afternoon. High temperatures will rise into the upper 80s with heat indices of 100-105. It’s important to stay hydrated while out having fun and remember, “When Thunder Roars, Go Indoors”.
A few thunderstorms may persist along the cold front early Wednesday morning before dry and breezy conditions return to the Rio Grande Valley through the holiday weekend as a ridge strengthens in northern Mexico. High temperatures will ramp up well into the 90s by Friday with triple digit heat for the upper valley Saturday and Sunday with muggy warm nights expected the entire weekend. Remember to stay hydrated while having fun outdoors, with heat indices expected to be into the 100s!
