Flash Flood Watch and Heat Advisory issued for parts of the state through Sunday evening
Quite a contrast in weather conditions is occurring today across the state of Mississippi with the threat of flash flooding to the south and dangerous heat to the north.
A very tropical fetch of moisture was feeding to the north on the eastern side of the remnant circulation of Bonnie and the overall upper low circulation over Texas.
This resulted in very heavy rain across portions of Southern Mississippi Sunday morning, prompting Flash Flood Warnings. Flooding was reported across the city of Columbia Sunday morning.
The flood warnings have since expired and the heavy rain threat has decreased but the possibility of re-development does exist with some storms capable of producing up to 2 inches of rainfall per hour due to the tropical airmass.
A Flash Flood Watch is in effect for portions of Southeastern Mississippi until 7 pm CDT Sunday evening.
This same tropical airmass feeding north across the state is combining with a lack of cloud cover across Northern Mississippi with temperatures surging into the 90s to produce heat indices above the critical danger level of 105 to 110 degrees, a level in which heat illnesses are possible if exposed to the heat for long periods of time.
Heat Indices were already in the upper 100s across these areas with a heat index of 107 in Tupelo and 109 in Columbus, as of the 3 pm CDT hour, and these readings are expected to rise further through the afternoon before the development of scattered rain and thunderstorms.
A Heat Advisory is in effect for Northern Mississippi until 8 pm CDT Sunday evening.
