Chance of Freezing Rain Starts Sunday

SAN ANGELO – There is a slight chance of freezing rain Sunday morning in the Concho Valley as a storm system brings in a rainy week.  In the overnight hours, anticipate another chilly night with temperatures dropping below seasonal norms. Expect lows in the low to mid-20s. Stratus clouds will increase from south to north throughout the morning.

An upper-level trough will place West Central Texas in a southwest flow aloft. A disturbance in this flow will track across the region on Sunday, leading to isolated to scattered light showers. Daybreak temperatures will be below freezing, gradually warming through the day. That will produce extensive cloud cover and potential light precipitation, with highs expected in the mid-30s to lower 40s Sunday. Patchy light freezing rain is possible in the morning, initially in Crockett County and later in the northern Edwards Plateau and southern Concho Valley. By mid to late morning, and possibly in the afternoon, portions of the Big Country may also experience freezing rain. Temperatures should be in the low to mid-30s by mid to late morning, minimizing ice accumulation. Elevated surfaces might see minor accumulations, but impacts are expected to be minimal.

LONG TERM... (Sunday night through next Saturday) Issued at 157 PM: Sat Jan 20, 2024

Sunday night, temperatures will struggle to drop significantly. Some light freezing rain is possible, but with temperatures at freezing, accumulations and impacts will be limited. The warm front on Monday will bring much warmer temperatures, followed by another cold front on Tuesday, bringing temperatures back into the 50s. The remainder of the week is expected to be warmer, with temperatures at or slightly above normal.

Rain chances persist as shortwaves move across the southwest US into Texas. The best chances for rain are Sunday night into Monday, with another significant wave expected Tuesday into Wednesday. Moderate rainfall amounts of 1/2 to 3/4 of an inch are anticipated over much of the area.
