Snow Accumulation for Wednesday, January 2, 2019
Snow Accumulation for Wednesday

Freezing Rain and Snow through Friday across the Southern Plains
A winter storm is beginning to impact the region as an area of low pressure over the Gulf of Mexico brings moisture northward, A wintry mix is already occurring across central Texas, which is expected to spread north and west through the day. By the evening into the early morning on Thursday, the area of low pressure that is currently producing snow over the Southwest will interact with the system to the south. This will bring colder air into the region, allowing precipitation to transition to primarily snow across west-central Texas and southwest Oklahoma. Further east, a mixture of rain and freezing rain is expected. Snow accumulation will range 2-4 inches. Freezing rain accumulation up to 0.25 inch is expected.

Major Cities in Region: Lubbock, TX, Abilene, TX, Wichita Falls, TX, Lawton, OK, Oklahoma City, OK, Tulsa, OK

Snow and Ice Accumulation for January 2-4, 2018
Snow and Ice Accumulation through Friday

Excessive Rainfall from the Lower Mississippi Valley into the Lower Tennessee Valley through Thursday
As a disturbance over the Gulf of Mexico slowly moves northward today, it will be blocked by an area of high pressure over the central US, bringing it slowly eastward. Ample moisture, combined with the slow eastward progression, will result in training showers and thunderstorms. This will produce widespread rainfall amounts of 2-3 inches today. As the low continues to move eastward, it will begin to interact with another low developing across Oklahoma and Texas. This will further slow the system for most of the day Thursday, bringing an additional 1-3 inches of rain. Two day rainfall totals of 3-6 inches with locally higher amounts in excess of 8 inches are expected, allowing for a risk of localized flooding and flash flooding. By Thursday evening, rain will end as the low moves eastward.

Major Cities in Region: Shreveport, LA, Baton Rouge, LA, Jackson, MS, New Orleans, LA, Birmingham, AL, Knoxville, TN

Fog will begin to clear this evening as an area of low pressure begins to move into the Southern Plains and Gulf Coast.
