We’re heading down to the banks of the Rio Grande for our forecast this evening. Typically this time of the year, we can expect some high heat and a little bit of humidity. Is that the case today as well?

At 656PM, CT, Laredo was reporting a brisk 30mph gust with fair skies and a temperature of 84 degrees. Dew points were near 70, and the moisture rich environment provided an atmosphere that was active with precipitation. A line of thunderstorms ran from north of Victoria to north of Laredo. The storms nearest Laredo on the American side of the border are beginning to diminish, because they are driven less by any synoptic feature, but mostly on the diurnal interaction with onshore flow.
A remnant frontal boundary north of the Gulf Coast is leaching some moisture away from south Texas, but is more importantly allowing the space for high pressure to develop over the western Gulf. Scattered showers and thunderstorms will still be possible in Laredo tomorrow, owing less to the onshore flow, and more to the monsoon flowing through Mexico and north towards the dry line and the Front Range. As high pressure builds, it will interrupt the flow of instability into Laredo, and the end of the week projects to be dry, but much warmer.
