| Area Forecast Discussion National Weather Service Corpus Christi TX 624am CDT Monday April 27 2026 Issued at 125am CDT Monday April 27 2026 Previous cloud cover limited today's highs more than initially anticipated. Model guidance for tomorrow maintains that skies especially out west should remain mostly clear Monday and Tuesday. Therefore, with the presence of well above normal 850 mb temperatures in the 90th-99th percentile above normal highs will prevail at least for those two days. Highs will top out in the 90s to lower 100s out west, with heat indices around 100-110 degrees. This translates to Moderate to Major heat stress conditions. We strongly encourage the practice of heat safety in these conditions. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety. Wednesday while temperatures are expected to be relatively hot once again, cloud cover is expected to creep back into the region which could potentially limit those highs once again. During the latter part of the week, a front is expected to approach the region eventually stalling just to the north Wednesday night into Thursday. The front will finally push through the region as a near surface low develops in the West Texas region. Moisture is expected to converge along the front surging to around 2.0" which will lead to showers and thunderstorm chances around 20-60%. The highest chances will likely be in the Victoria Crossroads region, though we will continue to monitor the trends. In the wake of the front we can expect brief cool down from above normal temperatures down to around normal. Highs are forecasted to be in the 70s and 80s across much of the area through the weekend. Marine Issued at 125am CDT Monday April 27 2026 Gentle to moderate onshore breeze (BF 3-4) will continue through Monday night, before occasionally strengthening to fresh (BF 5) during the afternoon and evening hours Wednesday and Thursday. A cold front will push through either Friday or Saturday, leading to fresh onshore flow ahead of it, followed by a strong northeast breeze (BF 6) in its wake. There is a low to medium (20-50%) chance of showers and thunderstorms Friday through Saturday. SCEC to Small Craft Advisory conditions will be expected in the wake of the front Friday night. Fire Weather Issued at 125am CDT Monday April 27 2026 Elevated fire weather conditions are not expected this week. Minimum relative humidity will drop as low as 30-35 percent over the Brush Country each afternoon, but winds will likely remain below elevated criteria. Temperatures will heat up early this week with highs in the triple digits over the Brush Country through Wednesday before a cold front approaches and impacts South Texas in the latter half of the week. The cold front will push through either Friday or Saturday, leading to low rain chances, increased cloud cover, and a decrease in temperatures.
