RIO GRANDE VALLEY:
Some much needed rain continues to fall over South TX at this hour because of a surface trough that pushed onshore. Not only is this causing precipitation to fall, but also helping the current drought in the RGV. Warm, Gulf temperatures helped keep the lower Valley a tad bit warmer than the upper Valley. Temperatures today reached 67 in Brownsville, 66 in Harlingen, and only 57 in McAllen. For tonight, expect much of the same, rain, drizzle and possibly a few thunderstorms embedded in the rain, as a mid-level low passes through the Valley, late tonight. Lows will be in the 50s throughout the Valley, with winds out of the west at 5 mph. Flash flooding may be an issue in areas with poor drainage. Please be cautious and aware of rising waters.
(1/16): Tomorrow will start of with showers, some heavy, and isolated rumbles of thunder (60%). By mid-afternoon, the rain should diminish, leaving skies mostly to partly cloudy. Afternoon highs will be in the mid-to-upper 60s with west southwest winds at 5-10 mph. Sunday evening will be partly cloudy with lows in the upper 40s/lower 50s.
M.L.K Day (1/17): Mainly sunny skies will dominate on Monday, with highs in the mid-to-upper 70s. Winds will generally be out of the south at 10-15 mph. Monday night will be mostly clear with lows in the mid-to-upper 50s.
(1/18): Tuesday, a weak cold front will pass, shifting our winds out of the north northwest at 10-15 mph, with gusts up to 25 in spots. No strong changes in temperatures with this front. Skies will be sunny, with afternoon highs flirting with 80 degrees. Tuesday night will be partly cloudy with lows in the lower 50s.
