Weather forecast for today
Today, on Tuesday, September 15, mostly sunny skies are expected. Minimal precipitation is forecasted. A high of a fiery hot 100.4°F during the day contrasts markedly with a low of a warm 73.4°F at night. The maximum heat index, which factors the actual air temperature with the relative humidity, is appraised at a life-threatening 122°F. Note that heat index values are valued for light wind and location in the shade. Bear in mind that direct sunshine exposure increases weather impact and may raise the heat index by up to 15 Fahrenheit degrees. It will feel hotter than usual, as the temperature reflects August's normal high of 88°F, not September's. Sunrise was at 6:42 am and sunset will be at 7:09 pm; the daylight will last for 12h and 27min.
Weather forecast for tomorrow
On Wednesday, in St. Louis, clouds will come and go, but expect bright periods in between. The maximum temperature will be a very hot 95°F, while the minimum predicted temperature is a moderately hot 73.4°F. The maximum heat index, which adjusts the air temperature based on humidity, is estimated at a burning hot 118.4°F. Take into consideration that the heat index values are calculated for shade and light wind conditions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit degrees. The higher temperature of 95°F is more typical of August than September. Sunrise will be at 6:43 am and sunset at 7:07 pm; tomorrow's daylight will last for 12h and 24min.
