Today will be one of change weather-wise across Texas as we see moisture spread north and clouds increase. After progressing south as a cold front on Sunday and Monday the front that swept out moisture north of it will become a warm front. As it moves north today it’ll bring rain chances northward. The severe weather threat is marginal today and mainly confined to the Rio Grande Valley and Deep South Texas. Areas of showers will be possible across Texas today but the rain chances will increase late tonight into Wednesday. The Weather Prediction Center is forecasting widespread rain amounts of 1 to 3 inches through Thursday afternoon across most of Texas. That kind of rain will cause more flash flooding in areas that are already saturated. In addition to flash flooding we also have to be concerned about river flooding and potential lake releases in locations that are already having problems. Any additional rain will only exacerbate river/lake levels. Some folks still need all the rain they can get especially in Northwest Texas so they’ll take it. Flash Flood Watches go in effect later today for areas that could see issues with flooding. Keep in mind that River Flooding will be a problem downstream in the days to come across South-Central and Southeast Texas with big rises to your north.
