Heat Advisory Through Thursday, Rain Not Likely Until Late Friday
Tuesday Night Forecast Update
Tuesday Night Forecast Update for August 10th:
The National Weather Service has issued a heat advisory through Thursday for all of West Tennessee. The heat index will be well above 100° for everyone the next 2-3 days until the cold front passes on Friday. The front will bring a change in the wind direction and a drop in temperature, but will it bring rain showers and thunderstorms with it as it moves through? We will have your full forecast coming up right here.
A heat advisory has been issued by the National Weather Service in Memphis for portions of West Tennessee through Thursday evening and could be extended through Friday for many of us. Heat indices will range between 105-110° at times for the remainder of the week. According to the NWS, you should:
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.
Skies will remain mostly clear tonight and rain showers are not expected. A stray shower or two cannot be ruled out but I wouldn’t count on seeing much. It is going to remain warm and humid with overnight lows falling into the mid 70s. Winds will stay light out of the southwest.
The heat will continue to climb into next week as southerly flow will continue to dominate our weather. This will allow temperatures to continue to rise as high as the mid 90s with a heat index over 100° due to the humid air mass that will be lingering across West Tennessee. Morning lows will only drop into the mid 70s for the middle of the week. Pop ups shower chances sit around 10% each day, so significant rainfall or severe weather is not expected.
A cold front is expected to move through West Tennessee towards the end of the week and into the first part of the weekend. The timing of the front could change but right now it looks to pass through late Friday and will bring some gusty thunderstorms with it. Highs will stay in the 90s until the front passes by and then highs are expected to fall back into the 80s. The winds will stay out of the southwest as well until the front passes and then expect the humidity to decrease and the winds to shift to the north.
Behind the cold front, temperatures are expected to cool down some for the weekend. Highs will fall into the 80s behind the cold front and morning lows will dip back into the 60s. Some shower and storm chances are expected to linger into the day on Saturday depending on the timing of the cold front. Sunny skies and less humid weather is expected on Sunday with the winds forecast to come out of the north as the cold front moves away from us and high pressure moves back in.
We are watching a cluster on thunderstorms that is likely to become the next named system of the 2021 hurricane season. The system is forecast to move toward Puerto Rico on tonight. By mid-week it would be near the island of Hispaniola.
Most forecast models are showing the storm moving into the Gulf of Mexico and if it does, we will be needing to keep a closer eye on it in the Storm Team Weather Center and look for possible impacts to our forecast here in West Tennessee.
Not only are we now officially in tropical storm season, we are still in the middle of our severe weather season. So you need to stay weather aware to changing weather patterns and monitor the forecasts closely. We got you covered in the WBBJ 7 Storm Team Weather Center as always.
