Near record breaking temperatures expected again today across the Rio Grande Valley prior to a cold front expected into the northern ranchlands this afternoon and through deep south Texas by tonight. Partly cloudy skies with highs into the upper 80s and low 90s. Isolated showers along the coast and breezy winds, to near Gale force at times off the coast are possible with the frontal passage this evening through tonight. Marine conditions this morning may improve some this afternoon before deteriorating rapidly this evening and overnight. Small craft should exercise caution on all Gulf waters today. A Small Craft Advisory for winds is in effect for the Laguna Madre from 9pm this evening until 8am Sunday. A Gale Warning is in effect for all Gulf waters out 60 nautical miles east of Padre Island from 9pm this evening until 8am Sunday.
A moderate risk of rip currents is expected today across area beaches. If you decide to enter the surf, use caution and remain in shallow water, especially in the vicinity of the South Padre Island jetties. Conditions this afternoon may improve for a few hours under partly cloudy skies with highs in the mid 80s. Rapidly deteriorating conditions return this evening and tonight due to the approach and passage of a cold front.
Winds will be breezy early Sunday with the final push of much cooler air into deep south Texas and the Rio Grande Valley. Well below normal temperatures rule through Monday before a quick near normal resurgence on Tuesday. Another cold front will dip temperatures back into the low and mid 70s into late next week.
