Tomorrow, on Thursday, a partly cloudy outlook will keep the sky interesting throughout the day.
Rainfall is not expected. Temperature span will be from a high of a tropical 33°C to a low of a temperate 25°C.
The maximum heat index, which integrates air moisture with ambient temperature, is computed to be a dangerously hot 46°C. Take into consideration that the heat index values are calculated for shade and light wind conditions. Bear in mind that direct sunshine exposure increases weather impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees.
This predicted maximum temperature is expected to mirror October's typical high of 31.1°C.
