With repeated rounds of rain persisting through the end of the workweek leading to saturated soils, flash flooding will become a concern on Thursday and Friday despite low amounts of instability in the atmosphere, the FOX Forecast Center said.

Snow expected in southern High Plains, Rockies

Snow is likely on the western side of the system, especially from the southern Rockies into the southern High Plains. This includes a significant portion of New Mexico's eastern half and the Texas and Oklahoma panhandles.

Winter Storm Warnings cover parts of New Mexico, southern Colorado and a sliver of the Oklahoma and Texas panhandles.

The FOX Forecast Center said some areas in the Texas and Oklahoma panhandles could pick up 1-3 inches of snow, while the elevated terrain in New Mexico and Colorado has the potential to receive up to a foot of fresh snow by the end of the week.

"The big snow totals will be up in the mountains," FOX Weather Meteorologist Britta Merwin said. 

"Texas stays in all rain," Merwin added. "This is probably the best news that you could ask for. We will have to look out for the panhandle, but in terms of Dallas, Houston, San Antonio, Waco and Austin, it's all going to be above freezing, and these are areas that can really battle with ice storms."

HOW HEAVY IS IT REALLY GOING TO RAIN?

Some models indicate that heavy rain will occur widely across Florida and the Southeast by the end of the week. However, the most trusted models suggest that heavy rain will be concentrated in southern parts of Florida, or even farther south, due to high pressure at the surface.
