As a mid/upper level ridge traverses across the CONUS this week, a series of shortwaves will move across Texas and northern Mexico. While we will see increasing moisture on Tuesday into Wednesday with the approach of a shortwave, chances for precipitation will remain limited. The latest GFS (Global Forecast System) guidance has backed off on POPs, coming more in line with other models with rain chances remaining below 10% for this event. The atmosphere begins to dry out again Thursday night, which will keep conditions dry through the week. As we head to the end of the forecast period, models indicate another trough swinging through the Plains bringing a cold front through the region on Saturday or early Sunday. At this time moisture is limited with this front and precipitation chances are under 10%. Light northeast to easterly winds turn southeast by Thursday allowing for humidity and temperatures to increase. Temps will remain in the mid to upper 70s through Thursday, with low 80s possible by Friday and Saturday. The aforementioned cold front looks to drop temperatures below seasonal norms by the end of the weekend. Overnight lows will climb back into the 60s by late week with 40s and 50s possible after the frontal passage.
