Humidity continues for North Texas as tropical system develops in Gulf
NORTH TEXAS — What looks to become Tropical Storm Alberto is quickly developing in the southern Gulf of Mexico, our first named storm of what promises to be a very active Atlantic hurricane season.
The big story continues to be the developing tropical storm in the Gulf of Mexico. It is forecast to become "Alberto" and come onshore in northern Mexico by early Thursday with 60mph winds
This system will push a plume of tropical moisture into North Texas. With the additional moisture, we expect more cloud cover and better rain chances. The best chance for both will be Wednesday on Juneteenth.
Rain chances on Tuesday look much the same as Monday, mostly in the eastern counties and rather modest.
Storm chances peak on Wednesday and Wednesday night.
There is a flood risk with these storms. With such a tremendous amount of moisture in the air, these storms could produce very heavy rain. The highest risk is confined to our most southern counties, along and south of the black line.
The First Alert Weather Team will monitor this threat throughout the day and evening on Wednesday. Severe weather is unlikely but gusty winds and frequent lighting will be around along with the flood threat.
These rain chances carry into Wednesday night and all the way to the start of the day on Thursday. As the system comes onshore in Mexico, it pulls the rain chances down to our southwest. There is a risk of dangerous flooding in southern Texas this week.
In one way the rain is welcomed, where the heavy rain is forecast is also where there are areas of exceptional drought.
As soon as the rain chances leave (by mid-morning Thursday), we get right back to hot summer weather. Still, no triple-digit highs are forecast but feel-like temperatures will be in that range by next weekend.
