1:30am Thursday August 2nd, 2018 - Chief Meteorologist Chris White
A deep trough will move east and interact with a ridge of high pressure located over the Atlantic. Pieces of upper level energy will rotate through the trough and interact with the warm and moist flow off the Gulf of Mexico and Atlantic. This will increase rainfall rates where the convection gets going. A narrow band of convection will likely develop and train over the same areas repeatedly where this trough runs into the Atlantic Ridge. With the highest precipitation rates of the week across the region today we are expecting areas of significant flash flooding.
A little more alarming is that confidence has increased in a surface low that moves North on this evening into Friday. Precipitation rates will likely now max out this afternoon into the predawn hours on Friday Morning. Additional rainfall on the order of 1 - 5 inches are likely. Most of our area will receive anywhere from 2-4 inches of rain. There could be much higher localized totals than this. The Flash Flood Watch is in effect until 8:00am Friday Morning. Landslides and flash flooding are probable, especially this evening into the predawn hours of Friday.
As always keep it here and we will keep you abreast of the latest developments. Please see the futurecast radar in seprate briefing below.
