DISCUSSION

Issued at 1128 PM CST Sat Jan 17 2026

A deep trough over the eastern CONUS today will slowly translate eastward throughout the week with a more zonal flow across the U.S. by next Saturday. In the meantime were expecting moisture to increase accompanied by a couple of cold fronts around midweek and again next weekend thereby increasing rain chances with each system.

The first cold front is expected to approach our CWA Tuesday morning and stall. Meanwhile a weak trough from the eastern Pacific is progged to deliver Pacific moisture and will likely increase our rain chances to a moderate (40-50%) late Tuesday night, and a moderate to high (55-80%) Wednesday. The second and stronger cold front is likely to push through our CWA late Saturday into Sunday morning of next weekend but rain chances remain low at this time.

Hazards:

A freeze warning is in effect across coastal Refugio and all of South Texas inland locales for temperatures near or slightly below freezing for several hours this morning. Wind chills are expected to range 25-35 degrees.

A Fire Danger statement is in effect today 9 AM TO 8 PM for all of South Texas except for the barrier islands.

Temperatures:

We start off the morning with low temperatures expected to bottom out around the 30-40 degree range between 13-14Z. Highs today will warm to the low to mid 60s. Tonight, lows will hover just above freezing across northern counties with mid 30s inland and 40-50 degrees near the coast. Monday, we warm back to the low 70s across much of the region, with overnight lows Monday into Tuesday in the 40s and 50s. A bit cooler Tuesday with a cold front in the vicinity around 60-65 degrees, followed by a warming trend through the end of the week with mid 70s to low 80s returning by Saturday. Another cold front late Saturday/early Sunday of next week is expected to lead to another cooldown Sunday and Sunday night.

MARINE

Issued at 1128 PM CST Sat Jan 17 2026

A Small Craft Advisory remains in effect until 7 AM this morning across all the waters as hazardous marine conditions slowly improve. A moderate to fresh (BF 4-5) northeast breeze will diminish throughout the day today becoming a light to gentle variable breeze by this evening. Flow will increase tomorrow to a moderate to fresh onshore breeze for much of the remainder of the week. Low to moderate chances for rain Tuesday will steadily increase to a high (80-90%) chance through Wednesday before dropping back to low chances by Thursday.

FIRE WEATHER

Issued at 1128 PM CST Sat Jan 17 2026

Critically low relative humidity values are expected today (15- 20%), drier air will linger through early in the workweek with minimum RH values improving to 25-40% Monday. By Tuesday, RH values expected to be above critical levels. Although winds will be light today, elevated fire weather conditions are expected once again due to the critically low RH values, high Energy Release Component values in the 80-94th percentile and dry to critically dry fuels.
