Brownsville, Texas

Brownsville is part of a surprisingly well populated stretch in the far southern part of Texas, including Harlingen and McAllen. Brownsville is the furthest south, and closest to the Gulf of Mexico. It also happens to be significantly further from any town, excepting Harlingen and McAllen, than anyone really expects.

At 953AM, CT, Brownsville was reporting a temperature of 83 degrees with clear skies. A dry line was spread through central Texas, and while the Dallas area had dew points in the the 40s, it was already in the mid 70s along the Rio Grande. There was a threat for strong thunderstorms closer to Corpus Christi this afternoon, and some of those shower and thunderstorms flaring south towards Brownsville can’t be ruled out later today. Additionally, Tropical Storm Karl was churning away in the Bay of Campeche. Tropical Storm Warnings extended to Matamoros on the other side of the Rio Grande, but his presence only raised the threat for coastal thunderstorms this afternoon.
Karl is moving southward, expected to landfall near Coatzcoalcos on the Campeche coast, so the attention will be turned to the dry line to the north of Brownsville. Without the counterclockwise rotation from Karl, the dry line will lose it’s potency as well. The dry line dichotomy will linger through the period, but the threat for showers and storms will abate over deep south Texas. As Karl continues to waste away in Central America, Brownsville will be more stable than normal for a hot humid stretch, with mostly sunny skies and temperatures preparing to climb.

Its strange that the driest forecast is the coolest forecast. Strange. Karl is showing up dramatically on the Gulf satellite imagery.
