After a dry start to October, the upcoming week looks to be very wet across a large part of Texas.
The pattern will yield not only needed rain, but the risk of flash and urban flooding, as well as travel delays.
Rainfall in the Lone Star State this weekend is just the start of what will likely turn out to be a very wet pattern into the coming week.
From Sunday midday through Tuesday, rainfall on the order of 2.0-4.0 inches will fall from Dallas into Abilene, San Antonio and Longview. Elsewhere, rainfall will range from 1.0-2.0 inches in areas like Houston and Amarillo.
Heavy rain in developed areas can lead to extensive urban flooding across major cities such as Dallas, Waco and Austin, Texasto name a few.
According to the Texas Department of highways, during Sunday morning, many low water crossings around Austin were closed due to high water.
Small streams and dry washes can also quickly fill with water in this pattern, causing flash flooding.
Along with the danger off flooding, the pattern will bring great beneficial rainfall to many areas.
Prior to this wet pattern, precipitation totals through the first 12 days of October are running well below where they should be.
Dallas, Texas, has had only 20 percent of the 1.22 inches it should have received since Oct. 1. Similarly, San Antonio has had only 16 percent of the normal 1.40 inches for the first 12 days of October. These numbers are repeated throughout most the state.
A cold front will stall across central and northern Texas into the middle of next week, while a potent storm developing in the Plains draws tropical moisture from the Pacific and from the Gulf of Mexico.
The end result will be periods of moderate-to-heavy rain and thunderstorms from into at least Monday. Additional drenching rain will fall over southern and eastern parts of Texas through Wednesday.
