Marine Weather and Tide Forecast for Lakeway, TX

SHORT TERM
(Today through Sunday)
Issued at 1218 AM CDT Sat Jul 25 2026

Mid-level ridging centered across the Four Corners into the Texas and Oklahoma panhandles will remain the dominant weather feature in the short term and beyond. This and a light to moderate southerly low-level flow will result in a seasonably hot and humid weather pattern this weekend. Highs trend in the mid to upper 90s and overnight lows in the mid 70s for the majority of the region. Heat indices peak in the 100 to 106 degree range along the I-35 corridor east through the Coastal Plains and for locations along the Rio Grande. The short term period likely sees slightly more cloud cover compared to the long term below given residual area soil moisture from recent rains. This would include the formation of some low stratus into the early to mid-morning period before eroding into partly cloudy to mostly sunny skies in the afternoon.

LONG TERM
(Sunday night through Friday)
Issued at 1218 AM CDT Sat Jul 25 2026

The mid-level ridging will keep a persistent forecast in place for all of next week with continued rain free and hot weather across South-Central Texas. The ridge does slowly amplify and slightly nudge southward with time. This helps to tick the temperatures upward by a few degrees by the end of the week. However, afternoon heat indices don't budge much compared to the values within the short term as diurnal mixing becomes a little more efficient. We'll monitor those temperature and dew point trends, but for now the conditions are a little shy of the heat advisory criteria mid to late next week. Otherwise, a light to moderate south-southeasterly flow maintains under mostly sunny/clear skies.
