Tropical storm Don is edging closer to the South Texas coast this morning - and should hit land sometime late tonight or early tomorrow morning between Brownsville and Matagorda. The storm itself looks healthier on this morning's satellite, but it's still facing some wind shear on the northern side that is helping to keep it from developing further. Add in the dry air near the Texas coastline in the upper levels (tropical systems feed on moist air, too), and Don should only get to about 65 mph before it hits the beach. The steering winds for the storm are from the huge high pressure ridge over the S/MW/SW blowing it WNW. That ridge is actually gaining strength this morning, causing Don to turn westward... meaning the chance of good rain is almost out the door for Northern/Central Texas. My fingers are crossed, but the rain field just doesn’t look too big. Three to five inches are likely for southern Texas.
The upper half of the nation is active this morning, too. There are plenty of impulses running through the atmosphere from the MW to the NE, and tough storms with heavy rain and frequent lightning have been hitting from Chicago to Buffalo and beyond. Ill have the forecast for you on the show.
