AUSTIN (KXAN) -- The last two days of fall are expected to stay hot. Temperatures are holding onto summer as long as they can with Saturday and Sunday sitting around the mid to upper 90s. With humidity, highs in the upper 90s will feel more like low 100s. Weekend forecast A bit of a change next week as we look ahead. A front is moving into northern Texas before becoming a stationary front on Tuesday. This will allow for some instability and give us a chance of showers through Wednesday. By Wednesday evening the front is expected to finally push through clearing skies up and returning to a normal weather pattern. Tracking the Tropics A broad area of low pressure has potential to become further organized in the Caribbean into next week. Chances for development are now up to 40%.
