...PRECIPITATION CONTINUES OVER NEW MEXICO AND TEXAS OVER THE NEXT COUPLE OF DAYS...

An upper level trough along the Pacific coast is deepening as it moves to the east. This system is expected to continue to generate upper level disturbances that will bring widespread precipitation across New Mexico and Texas through Saturday morning.

For New Mexico, another trough will pass eastward today over the state leaving additional snow at higher elevations by the time it leaves the state. The most favorable areas for precipitation remain focused on the central parts of the state.

For Texas, light scattered showers and drizzle are slowly moving east with light rain remaining possible mainly for the I-35 corridor and points east. The Hill Country and points to the south including Corpus Christi and points east northeast to the Louisiana border are expected to receive the heaviest amounts into Friday. The following 24 hours from Friday into Saturday, the eastern third of Texas will be the focus of the next round of precipitation. This period may see rainfall totals in the 1-3 inch range.

The next potential for precipitation is Monday and Tuesday over north central New Mexico and over the northern portions of Texas.
