This week’s weather will start out very hot, with a couple of days in the 100s, before giving way to some blessed relief. How much relief? A lot say forecasters with the Houston/Galveston office of the National Weather Service, as by mid-week the high pressure system that’s baked Houston this summer moves out of the area and is replaced by a lot of tropical moisture.The following map shows the GFS model’s estimate of accumulated rainfall for the southeastern United States for the next week. All of a sudden, half of Texas is no longer completely dry.
Some shower and thunderstorms could start as early as Wednesday, but I think main influx of moisture will commence on Thursday. It’s a little too early to tell how much rain we may receive during the first week of September, but since we will be dealing with deep tropical moisture several inches of much needed rain accumulate across parts of the Houston area. In addition to the rain, afternoon temperatures are forecast to decrease to more seasonal levels from September 1-5 and average in between 90 and 95 degrees.
As for the tropics we always become concerned when this type of a flow pattern develops during September as high pressure over the southeast U.S. allows tropical moisture to build up across the western Gulf of Mexico. Current projections indicate winds aloft will be slowly improving late next week, so we will be paying extra close attention to this region for any signs of tropical development.
Nevertheless some models are even predicting the approach of a cool front by next Monday that would bring some even cooler air into Houston.Tonight: Mostly clear, with a low around 75. East wind between 5 and 10 mph becoming calm.
....Enjoy!
