SHORT-TERM FORECAST: SEA BREEZE SHOWERS, STORMS, AND SOME SUN
Isolated to widely scattered, weaker thunderstorms and heavier showers will be the main story over the next 2-3 days as the very weak tropical disturbance sitting off of the Texas' coastline continues to propel moisture inland. Our higher-pressure has receded slightly, allowing for afternoon and evening storms to initiate in our humidity and warmth.
For Saturday night into Sunday morning: very slight chances of rain across the region, "popcorn" showers and storms will be the main form-very hit-and-miss, and not everyone will see the rain. Sunday late, into Monday-chances improve across Central Texas, and brief, heavy downpours are possible along with very active lightning-not unlike what we saw Friday night. Cloud-ground lightning is also possible.

* WATCHING CLOSELY: INVEST 99L AND THE GULF OF MEXICO*
Well, this is complicated. The National Hurricane Center even admits, this is a challenging forecast. The "ensemble" model runs (or those maps with all of the lines of possible tracks) for Invest 99L continue to fluctuate; ALL of them. Yesterday, most of the ensembles depicted a strenghtening tropical system that eventuially tracked east over Florida, and some towards the north, over the southeast United States-Georgia, etc... UNTIL late last night when the majority of the tracks and ensembles took the system straight west-towards TX and LA! This same pattern has been occurring for around 3 days now. One run-showing the system moving east, the other-west towards us. The National Hurricane Center caved and decided to draw a track right in the middle, but they've slowed it's development chances as it continues to stall just south of Florida. As of this writing, the latest ECMWF European model run (traditionally very accurate) has a moderate-strength hurricane forming over the Gulf and making landfall near the Texas and Louisiana border sometime late next week. For this reason, we are watching the Gulf of Mexico closely. Right now, anything is possible and all of the data can change.
