This weekend will be extremely muggy with feels like temperatures reaching near 114 degrees Saturday and Sunday. Next week, the rain we have all been hoping for is looking less and less likely. 

 

An ***EXCESSIVE HEAT WARNING*** is in effect from 10am Saturday until 7pm Saturday for the entire WBRZ Viewing Area. Dangerously hot conditions with heat index values up to 114 expected. Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. 

An ***AIR QUALITY ALERT*** is in effect until midnight on Saturday. The Air Quality Index indicates that ozone will be at the Orange level, which is unhealthy for sensitive groups. Increasing ozone levels may cause unhealthy air quality during afternoon hours. Active children and adults, the elderly, and people with respiratory diseases such as asthma should avoid prolonged outdoor exertion.

Tonight & Tomorrow: Tonight, the low temperature will start getting warmer once again, and it could fail to leave the 80’s under clear skies. Tomorrow, oppressive heat will be in full swing, with temperatures maxing out near 103 degrees under mostly sunny skies. Feels like temperatures because of high humidity could get to near 114 degrees! Rain will be almost non-existent and the vast majority of areas will remain completely dry.

Up Next: This weekend is shaping up to be a hot and humid one with mostly dry conditions. Some rain will be possible Monday into Tuesday, but these days are unfortunately trending drier. Coastal areas have the best shot at rain on these days. Potentially record breaking temperatures then return by the middle of next week.

The Tropics: 

  1. Eastern Tropical Atlantic (AL98): Showers and thunderstorms continue to show some signs of organization in association with a broad area of low pressure located a few hundred miles west of the Cabo Verde Islands.  Environmental conditions appear generally favorable for additional  development of this system, and a tropical depression is likely to  form over the weekend while it moves toward the west-northwest or  northwest at about 10 mph across the eastern tropical Atlantic. By early next week, upper-level winds over the system are forecast to  increase, and further development is not expected.

  1. Central Tropical Atlantic (AL99): An elongated trough of low pressure located roughly halfway between the Cabo Verde Islands and the Lesser Antilles is producing some disorganized showers and thunderstorms. Environmental conditions are only marginally conducive for further development of this system, but a tropical depression could still form during the day or so while it moves west-northwestward at 10 to 15 mph across the central tropical Atlantic. Thereafter, upper-level winds are forecast to become unfavorable for any further development.

  1. East-Southeast of the Lesser Antilles: Another area of low pressure could form in a day or so from an elongated trough of low pressure located several hundred miles to the east-southeast of the Lesser Antilles. Some slow development of this system is possible over the weekend and into early next week as it moves generally west-northwestward at 10 to 15 mph across the Lesser Antilles and into the northeastern Caribbean Sea.

  1. Western Gulf of Mexico: An area of disturbed weather located over the southeastern Bahamas is forecast to move into the Gulf of Mexico by early next week, where a broad area of low pressure could form. Thereafter, some slow development of this system is possible and a tropical depression could form as it moves westward and approaches the western Gulf of Mexico coastline by the middle of next week.
