1. Wednesday we had a frontal boundary move further south than expected with the last forecast update into the region at the same time a band of thunderstorms developed just south of the boundary which moved very slowly and west to east across the region resulting in flooding in particular for areas just north of Bowling Green. Today and Saturday a ridge of high pressure will break up and send the boundary northward leading to hot and muggy weather ( 90’s for highs and low 70’s for lows and heat index values of 100-105). Make sure to keep in this mind if outdoors as a heat advisory is in effect.
2. Tropical depression Bonnie is located just south of Tampa,Florida tonight and is expected to move northwest into the gulf making landfall early next week near New Orleans. This system looks very week now with the likelihood of becoming a storm again not that great sue to an unfavorable position of the upper level low and increased shear near it’s path. The moisture from Bonnie should move north into our region by Tuesday. At the same time another front will push south through the ridge enough to make it into the lower Ohio valley before stalling and weakening over our region. The combination of these two systems will lead to likelihood of afternoon and evening showers and storms with a heavy rain threat. Right now this front& tropical leftovers should be over the region with thunderstorm chances from the front on Sunday entering the region and the tropical moisture addition for Monday through Wednesday. Highs should be in the low 90’s Sunday and in the mid to upper 80’s Mon-Wed thanks to clouds and storms with lows from 66-72.
