An extended period of summer heat will continue for the next seven to ten days. August is typically our hottest month and this year looks to be no different. High temperatures will top out in the upper 90s to mid 100s this afternoon. Heat index values of 103 to 110 degrees are expected from near and east of Interstate 35. The higher heat index values are caused by higher humidity values. For that reason heat advisories are now posted across much of Northeast Texas and East Texas. I would not be surprised to see those advisories expanded both spatially and in duration as we continue towards the weekend. The monsoon is picking up in the Southwest United States. That monsoonal flow will help bring scattered showers and thunderstorms to Far West Texas later today. Isolated activity will be possible in the western Texas Panhandle and West Texas as activity tries to move in from New Mexico. Severe weather is unlikely but gusty winds and spotty heavy rain may occur.

Tropical Storm Earl is nearly a hurricane this morning as it moves towards Belize. This system is forecast to make landfall tonight in Belize as it moves west around 13-14 MPH. The high pressure aloft over the southern United States continues to push Earl west. At this point it seems unlikely that it will make it to the Gulf of Mexico, not to mention have any impact on our weather here in Texas. Hurricane season is just ramping up and we will need to remain vigilant through early October.
