SHORT TERM
(This evening through Sunday Night)
Issued at 149 PM CDT Sat Jun 14 2025
CONUS wide water vapor satellite imagery and 500 mb RAP analysis shows a distinct ridge over SW CONUS and another ridge centered over Florida. Between the ridges lies an elongated trough axis that extends from the Midwest down to southern coastal Texas. The trough axis isn't as defined over our area as it is over the Midwest. But nonetheless, troughing does exist over SE Texas and we have certainly seen the impacts of that today via heavy showers and thunderstorms. Some thunderstorms, especially near the coast, have been strong to severe. But the good news is that the atmosphere has become quite worked over. RAP surface CAPE analysis shows this via a "CAPE hole" over SE Texas. In other words, the RAP is interpreting our atmosphere to be on the stable side. Could we rule out enough heating and destabilization for isolated convective development this afternoon? No, we can't (especially if the 18Z HRRR has anything to say about it). But the next good chance of showers/storms appears to arrive tomorrow. There's some uncertainty as to whether or not this activity will hold off until the afternoon, or start in the morning like today. If we do have morning storms, they are more likely to occur near our southern/coastal counties. Once again, localized flooding along with a few stronger storms capable of damaging wind gusts will be the primary concerns.

LONG TERM
(Monday through next Friday)
Issued at 149 PM CDT Sat Jun 14 2025
For the long term discussion, I could go into detail about how we shift from the SW CONUS / Florida ridge with a trough in the middle pattern, to one that features increased ridging over E CONUS and a general shift of our mid/upper synoptic flow pattern to the southeast. But on the ground, you are unlikely to notice the change. It will remain warm and quite humid. A daily risk of showers and thunderstorms will continue through the end of the week. With those storms will come a risk of locally heavy rainfall along with a few stronger thunderstorms. It's a very rinse a repeat pattern. Some days are likely to be stormier than others, depending on which mesoscale features and processes decide to dominant the weather that particular day. So if you like the rain, great news for you! If not, our profound apologies.

AVIATION
(00Z TAF Issuance)
Issued at 550 PM CDT Sat Jun 14 2025
VFR conditions mostly expected through at least late evening followed by a mix of MVFR stratus (mainly north of the metro area)
later tonight. Will probably see some iso/sct activity begin developing south of I-10 and offshore between 12-15z, followed by an expansion/smattering of shra/tsra further inland in the 16-19z timeframe. One thing we'll have to keep an eye on is the remnants or outflow from tonight's storms in OK and north Tx that may sink into our region during the day Sunday and provide a focusing mechanism and convergent zone for additional afternoon activity.
Some of the storms today were on the heavy/strong side, and would anticipate that possibility again Sunday. 47
MARINE
Issued at 149 PM CDT Sat Jun 14 2025
Lingering showers and isolated thunderstorm activity should wane as the afternoon progresses. Winds this afternoon will be relatively light, but should increase from the southeast this evening into tonight. There will be another chance of showers and thunderstorms tomorrow near the coast. There is some uncertainty as to whether or not these storms will hold off until the afternoon or begin in the morning like today.
Despite some changes in the pattern aloft, the general pattern that we will experience at the surface remains generally the same through Tuesday. There will be a daily chance of showers and thunderstorms along with light to moderate onshore flow. The daily rain/thunderstorm chances will continue until the end of the week, while onshore flow and swell is expected to increase by Wednesday and Thursday.
