Thus far what was supposed to be a “wet” week has mostly been a dud in the rain department. However I still expect that to change on Wednesday, when there’s the potential for heavy rain.
TODAY
A weak front is moving through Houston this morning, however it’s going to stall off the coast, and not going to bring much cool air. Highs will be around 80 degrees today, and even with the frontal boundary we’re going to see moisture pooling over coastal areas. This will allow for a chance of light showers today, and the potential for heavy rain tonight and on Wednesday.
WEDNESDAY
Because of the front’s proximity to the coast, very high moisture levels, and favorable conditions in the upper atmosphere we’re going to see rain between late Tuesday night and noon on Wednesday. For Houston I’d guess the heaviest rain comes between about midnight and sunrise. Coastal areas could see widespread totals of 1 to 2 inches of rain, with lesser amounts inland. In addition we can’t rule out some isolated flooding where rain showers are heaviest. That’s always a concern when the atmosphere is this moist. Fortunately as high pressure moves in by Wednesday evening we’ll see an end to shower activity.
