Day 3 Surface Map


A weak tropical low is currently located off the coast of Texas south of Freeport this morning. This system will continue to track southwestward today and Thursday and will bring a surge of deep tropical moisture over most of the Texas Gulf coast. Unsettled weather will be prevalent, with scattered to numerous showers and thunderstorms likely each day into at least Friday. We will continue to monitor the progress of this low.

Elsewhere, the primary weather maker this forecast period will be from an upper level low pressure system currently over Utah. The trough which trails this low will move over New Mexico and Colorado on Thursday, initially affecting the Texas panhandle and the western parts of north Texas Thursday afternoon and night with showers and thunderstorms. Then the trough will move east into Oklahoma and north Texas and best chances of rain will be Friday over north Texas. This trough will then bring additional rainfall to primarily the upper Texas Gulf coastal region Friday night into Saturday before the trough pushes east of the forecast area on Sunday. The rainfall should decrease over Texas on Sunday night and Monday morning.

In New Mexico, showers and thunderstorms will become widespread today and tonight, then drier air will move over the state which will bring an end to the monsoonal rainfall from Thursday and thereafter.
