A Slight Chance for Rain Forecast the Second Half of the Week
June 16, 2025
Sunny and quiet weather conditions are in place as we start off the new week. The trough of low pressure over Oklahoma which helped kick off Sunday’s line of rain and thunderstorms has shifted to the east. At the same time, a large dome of high pressure centered over northern Mexico has spread further to the east since Sunday, creating a more stable atmosphere across much of Texas. Meanwhile, a somewhat unstable atmosphere continues across Deep South Texas, the coastal plains and Southeast Texas. A generally dry weather pattern is forecast across the entire region Tuesday and Wednesday as the ridge of high pressure expands further to the east across Texas.
For Monday and Monday Night
There will be 30 percent chance for scattered rain showers and thunderstorms across the coastal plains region Monday afternoon and evening. Widespread or heavy rain is not anticipated. Rain amounts should average less than a quarter inch. Expect high temperatures in the low 90s.
Across Central Texas, a couple of isolated showers and thunderstorms will be possible Monday afternoon and evening. Totals, if any, should measure less than a quarter inch. Expect a sunny sky with high temperatures in the mid-90s.
Across the Hill Country, expect sunny and dry weather with high temperatures in the low and mid-90s
Tuesday through Thursday
Sunny and dry weather is forecast across the entire region. Expect southerly breezes in the range of 10-15 mph. High temperatures are predicted to be in the mid-90s, with lower 90s towards the coast.
Friday through the Upcoming Weekend
A slight chance for rain will return to the forecast for all areas Friday through Sunday. Forecasts call for a wave of low pressure to push inland across northern Mexico late Thursday and the circulation around the trough is expected to pull higher levels of Gulf moisture inland. This is expected to result in the development of scattered afternoon rain showers and isolated thunderstorms. The probability for rain each day will range from 20 percent across the Hill Country and the I-35 corridor, to near 30 percent in the La Grange area and 40 percent for the coastal plains. Rain amounts each day are forecast to average less than a quarter inch.
High temperatures through the period are forecast to be in the low and mid-90s.
NWS Rainfall Forecast Valid through 7 pm Next Monday, 06/23
Looking out into next week, a chance for scattered showers and thunderstorms looks to continue throughout the week. Forecasts call for the center of the heat dome over northern Mexico to shift northeast to the Tennessee and Ohio Valley regions early next week, with the center expected to remain along the East Coast throughout the week. A moist flow off the Gulf into Texas is expected to cause a chance for afternoon showers and thunderstorms through the end of the month. High temperatures next week are forecast to hold in the low and mid-90s.
Tropical Weather Outlook
Weather conditions remain quiet across the tropical Atlantic and tropical cyclone development is not expected for the next seven days.
Summer Solstice Occurring Friday Night
The summer first day of summer will occur this year on Friday, June 20th at 9:42 pm CDT. As seen from Earth, the Sun will be directly overhead at noon 23.5 degrees north of the equator, at an imaginary line encircling the globe known as the Tropic of Cancer, named for the constellation Cancer the Crab, its northernmost point. The North Pole’s tilt toward the Sun is greatest at the solstice, so this event marks the longest day of the year north of the equator.
Have a good week!
