A change to rainy weather is expected across parts of Texas and Louisiana that desperately need the precipitation.

This rainy pattern will begin Sunday night and continue through Tuesday, bringing some parts of the region 2-4 inches of rainfall when all is said and done.

The same storm system which will bring Denver and Salt Lake City snow through tonight will translate southeastward on Sunday.

As this feature shifts into the southern Plains, it will spark the development of an area of low pressure in the northwestern Gulf of Mexico.

Moisture from the Gulf will interact with these dynamics, thereby sparking the development of rain and drizzle Sunday afternoon and evening from San Antonio, Texas, through Little Rock, Ark.

Rain will quickly increase in coverage and intensity later Sunday night and Monday, spreading soaking rains from central and eastern Texas through Louisiana, southern Arkansas, and central parts of the Gulf Coast.

The rain will fall steadily Monday and Monday night, especially from Houston and Tyler, Texas, through New Orleans, La., and Jackson, Miss.

These areas desperately need the rainfall as drought continues to plague much of the region.

Most of southeastern Texas and the western part of Louisiana continue to suffer from severe to extreme drought according to the U.S. Drought Monitor.

A bull’s-eye of 2 to 4 inches of rainfall is likely from eastern Texas through most of Louisiana and western Mississippi which will help to put a dent in the ongoing drought.

This rainfall won’t be heavy enough to cause any major flooding problems; however, some ponding on area roadways and poor-drainage areas will be likely.

The morning and evening commutes will also be tricky around Houston and Dallas, especially on Monday.

Always remember to take it slow in wet weather and allow plenty of distance between you and the car in front of you.

On Tuesday, this low pressure system will begin to lift northeastward, setting its sights on the eastern part of the country Wednesday and Wednesday night.

Unfortunately for snow lovers, the favored form of precipitation will once again be rain from Washington, D.C., through New York City and Boston.

Though behind it, residents of the mid-Atlantic and Northeast will receive another blast of cold, Canadian air for the end of the week. More details to come about that in the coming days, so, stay tuned to AccuWeather.com.
