Scattered showers and thunderstorms will continue through tonight into tomorrow morning and afternoon. As the front passes over head tonight, due to strong shear within the mid levels from the west creating instability along with warm air advection out of the south at the surface, severe thunderstorms will be possible beginning tonight between 8PM and 10PM lasting into the morning on Wednesday. Winds are expected to be sustained at 10-15 mph tonight with Gusts at 30mph increasing sustained winds to 20-25 mph by Wednesday afternoon. The National Weather Service has mentioned that the severe thunderstorms will be capable of producing 60+ mph winds, frequent lightning, and a small chance for tornadoes to develop in some of these supper cells. The front is expected to pass by Wednesday late afternoon into the early evening with cooler air behind it; dropping Thursday mornings lows in the low 30s with highs in the mid and upper 50s. However this will not last long. By Friday night, another frontal boundary system will makes its way into the Big Bend from the west increasing cloud cover and rain chances to 50% Saturday morning into the afternoon. By Saturday night that front will have cleared the area and we will be back to high pressure allowing temps to drop back to the low 60s for afternoon highs and lows within the upper 30s and low 40s.
