Southerly flow will bring daily thunderstorm chances through at least the weekend. Gusty winds, small hail and locally heavy downpours will be possible with any thunderstorm along with dangerous lightning. If you have outdoor plans, seek shelter if you hear thunder. Remember “When thunder roars, go indoors!” Also be sure to have multiple ways to receive forecasts and warnings.
Hot conditions are expected Saturday into Sunday. Don’t leave kids or pets unattended in vehicles. Drink plenty of water, and take breaks in the shade or air conditioning.
A Red Flag Warning is in effect for portions of the area today for abundant lightning on dry vegetation. This will likely lead to new fire starts and gusty thunderstorm winds could contribute to fire spread.
