KEY MESSAGES

Updated at 648 AM CDT Sun Apr 5 2026

- Rain to continue Easter Sunday and into Monday morning

- Below-normal temps through mid-week

DISCUSSION

Issued at 232 AM CDT Sun Apr 5 2026

A southwest to northeast oriented band of moderate to heavy has been fairly stationary across the northern counties for the past few hours. Mesonet sites are reporting rainfall totals in the 1-1.75" range, with the best coverage over Live Oak County. This rain is established within the 925 mb frontogenesis zone where training is ongoing. Additionally, we are monitoring a large MCS in Mexico which is approaching the Rio Grande Plains. This area of convection is occurring out ahead of a potent shortwave that has been moving across Mexico and expected to cross South Texas later tonight into Sunday. The KCRP VAD Wind Profile is showing a veering profile through the depth of the atmosphere with backing winds aloft indicative of the approaching shortwave. All this to say we have a good chance for much needed rainfall over South Texas in the next 12- 18 hours. The latest CAM guidance is showing that a widespread area of 1-2" if rain could still fall across the region during the aforementioned period with locally higher amounts near 3" possible. Rain chances will begin to taper off Monday morning as we dry out throughout the week.

Below normal temperatures are expected Sunday and into mid-week before returning to near normal values late in the work week. Above normal temperatures could be back in the forecast by the end of next weekend. Friday and Saturday will both feature low chances (15-25%) for showers with the best chances across the Coastal Plains and Victoria Crossroads.

AVIATION

(12Z TAFS) Issued at 648 AM CDT Sun Apr 5 2026

A mixture of MVFR to IFR conditions is ongoing across area terminals. These conditions will likely prevail through much of the TAF cycle with showers and thunderstorms remaining in the forecast through Monday morning.

MARINE

Issued at 232 AM CDT Sun Apr 5 2026

A moderate to fresh (BF 4-5) northeast breeze is expected tonight strengthening to a strong breeze (BF 6) Sunday morning and continuing through early Monday morning. Winds will gradually diminish Monday weakening to moderate breeze Monday night. High rain chances (70- 90%) will continue through Sunday night decreasing to a medium chance (40-60%) Monday before tapering off Monday night.

FIRE WEATHER

Issued at 232 AM CDT Sun Apr 5 2026

A cold front is currently sweeping across the region which will bring back below normal temperatures. Along the with the cooler temperatures, rain chances also continue through Sunday night. Relative humidity values in the wake of the front will remain above critical thresholds. Therefore, elevated fire weather conditions are not expected.
