6/28 – Night Rob’s “Beneficial Rain Continues” Tuesday Evening Forecast
Spotty downpours popped up again today, an increasing trend as we head through the week. Broad low pressure over the western gulf combined with high pressure over the southeast will continue that moist flow off the gulf. This, combined with a diffuse, stalled front over the area will be a daily trigger mechanism for afternoon/evening downpours. We’re down about 8 inches in rainfall for the calendar year, so we can certainly use this rain.
The area of disturbed weather over the Gulf of Mexico will drift slowly westward over the next couple of days, eventually arriving on the Texas coast on Thursday. It actually has a chance to spin up into a tropical depression briefly before it reaches Texas, but no impacts will occur here.
Elevated moisture will be at its lowest today but continue to climb Wednesday and Thursday. Most activity is expected to occur during the afternoon and early evening hours. Wind fields remain rather light, and that means very slow-moving storms after they form. Locally heavy rain will be a threat each day, but the threat of widespread heavy amounts is low. Overall, the heaviest rain days look to be Thursday/Friday. Regarding temperatures, anticipate very little change in overnight lows from night to night. High temperatures, of course, will be dependent on placement of storms.
There’s not really a lot of change in moisture levels for at least Friday and Saturday, and those days will look a whole lot like Thursday. Beyond Saturday, high-pressure tries to build back across the area, which would favor some (but not total) suppression in t-storm development, and slightly hotter temperatures.
