Area Forecast Discussion National Weather Service Brownsville TX 413 AM CDT Thu Sep 16 2021

.SHORT TERM (Today through Friday): A mid level low will move into North Texas today and gradually drift into East Texas on Friday. Even though weak mid level troughing will begin to build today, the overall pattern will be mainly hot and dry, except for a possible stray shower or thunderstorm that may drift northward across the Rio Grande this afternoon and evening, as the latest HRRR is suggesting. The mid level low will bring slightly improved upper level support for convection across portions of Deep South Texas tonight and on Friday. As this low drifts into East Texas on Friday, an axis of positive vorticity will drape across the northwest Gulf and provide a focus for convection over the lower Texas coastal waters and the southeast portion of our CWA. Temperatures will remain near normal through the period.

.LONG TERM (Friday Night through Wednesday): Isolated to scattered showers and thunderstorms are forecast through the entire period as closed 500 mb low pressure over the Lone Star States eases south and then transitions to a mid-level trough along the Texas coastline before lifting northeast. The best chance for rainfall will occur during the weekend during the low's closest approach to Deep South Texas and the Rio Grande Valley. Near to slightly above normal temperatures are also anticipated.

.MARINE (Today through Friday): Marine conditions will remain favorable through the short term with low wave heights and light to moderate winds. However, showers and thunderstorms will be possible throughout the period, with greater chances on Friday.

Friday Night through Wednesday: Small Craft Exercise Caution and Small Craft Advisory continue to not be expected during the period with a modest pressure gradient in place. Light to moderate winds and low to moderate seas are forecast.
