RIO GRANDE VALLEY
Scattered showers and thunderstorms developed once again in the Valley today. Most of the rain that fell was in Hidalgo and Starr Counties and were heavy, but very brief. Isolated areas did pick up a quick .75″-1″ of rain, though. It looks like the rain chances will begin to diminish as the weekend comes to an end and the Fourth of July starts, although I can’t rule out an isolated shower or thunderstorm for tomorrow or Monday. The unstable airmass over the Valley will begin to stabilize over the next few days, as a 500mb ridge builds over the area.
Sunday, 7/3: Sunday, there is still about a 20% chance of a shower or thunderstorm, but will not be anything like the past 2 or 3 days. Showers that do develop, again, will be brief and isolated. Expect partly cloudy skies with temperatures rising to the upper 90s over the next 2-3 days. Winds will out of the ESE/SE at 8-12 mph. Things will stay muggy during the evening, with temperatures in the middle and upper 70s
Monday, 7/4: Your 4th of July looks to be mostly dry and mostly to partly sunny. Can’t rule out a stray afternoon shower or storm. Winds will be out of the ESE at 10-16 mph. Partly cloudy evening is expected while you are out popping firecrackers with muggy temperatures in the middle and upper 70s.
Tuesday, 7/5: By Tuesday, rain chances will be slim to none as the upper level ridge will be in control of the dry, hot weather. Afternoon temperatures will be hot and humid, with temperatures crawling back in the upper 90s and even into the triple digits in some areas of the upper-Valley. Skies will be mostly sunny/partly cloudy.
There is a weak wave located near the Lesser Antilles, but conditions are not favorable for further development, as wind shear will be too great in the area.
Other than that weak wave, there are no other systems in the Atlantic, Caribbean Sea, or Gulf of Mexico to be concerned about.
