Showers Make A Comeback

Keep the umbrella handy Tuesday as a weak disturbance in the Gulf sends showers toward the upper-Texas coast. The last few days featuring warm, but not overly humid weather, and pleasant mornings is about to change.

High pressure in the Southeast U.S. will allow for southeast winds to develop, which always means a return of muggy weather to Houston. Additionally, there are signs of low pressure in the western Gulf of Mexico.

Typically, a low in the Gulf might raise a few eyebrows, even though we've reached the peak of hurricane season. However, the low is very weak and very disorganized. Also, there isn't high pressure aloft. The latter would make tropical development a bit more favorable.

Expect showers today to develop as those southeast winds send Gulf showers inland. The afternoon could be especially soggy and even in the morning, there may be considerable cloudiness. 

Once Tuesday's rain threat diminishes, the rest of the week looks rain free, although the southeast winds will make the days warm and muggy and the mornings not quite as pleasant as they have been recently. Lows should range in the mid to upper 60s.

Change On The Horizon

No sign of summer's end today as the heat beat wears on across the Lone Star. Nothing really unusual about that after Labor Day. However, there are signs of change later in the week. It is very likely that a cold front, currently dragging through the middle of the country is headed toward Texas.

Along the front, showers and in some cases, stronger thunderstorms are likely to develop. The front should make it through Dallas by Wednesday and then arrives along the Upper Texas coast by Thursday. Here is a projection for rain and the front then:

The slow-moving nature of this front means rain chances could linger well into the weekend. It's still a little early for THE cold front that puts and end to the seemingly endless summer, but it will be a welcome sign.

Soggy Start To September

Even though rainfall in August was .66" below normal, there were only five days with rain in Houston. So the forecast for wet weather over the next few days is a good thing. The image above shows the water vapor imagery for Texas. The bright white indicates moisture, the red area indicates dry sections. 

An upper-level disturbance near Corpus drifts slowly northward, spreading rain chances upward and inward today and tomorrow. With little steering it, showers could linger through late in the week. Here are projections for Tuesday and Wednesday:

There are no concerns as of yet for flash flooding as there should be decent breaks between rainfall episodes. Best advice: keep the rain gear handy.
