Tomorrow, on Monday, scattered thunderstorms are expected, bringing heavy rain and thunder at times.
The chance of rainfall is low, and light precipitation is predicted. A subtle difference will be noticeable between the daytime peak temperature of a humid 87.8°F and the nighttime low of a temperate 78.8°F.
The maximum heat index, which factors the actual air temperature with the relative humidity, is computed to be a steamy 102.2°F. Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
The temperature will be in line with June's average maximum of 84.6°F.
Sunrise will be at 05:53 and sunset at 18:50; tomorrow's daylight will last for 12h and 58min.
