This graphic comes from the Hydrometeorological Prediction Center and shows the expected rainfall totals for the next 7 days. As you can see by all the greens, blues, and purples, the chance of rain is going up! Like it has been for months now, the highest rainfall totals look to be along and east of Interstate 35. However, current data does show that rain will also likely occur west of Interstate 35 as well.
These rain chances are due to a series of storm systems that will move across Texas over the next few days. One of these systems will pass over on Wednesday and Thursday with a stronger storm system expected by the weekend. The weekend storm system could even bring stronger thunderstorms with it. We’re way too far out to worry about that possibility though.
Our Wednesday storm system will bring the highest chances of rain to areas near and south of Interstate 10 from San Antonio into Louisiana. Rainfall amounts will average half to three-quarters of an inch with isolated higher amounts possible. The rain chances will spread northward by Wednesday night into Thursday with accumulation amounts between a tenth of an inch and half an inch further north. Severe weather isn’t expected to be a big issue, but we will have to watch the Rio Grande Valley for a chance of stronger storms.
A stronger storm system looks to affect Texas by the weekend with the possibility of several days of rain and storm chances. We’re still quite a ways out so model guidance is still showing all sorts of different solutions. This system could bring beneficial rainfall and a chance of strong storms. We’ll have more on this system once we get past our Wednesday/Thursday storm.
