The short-term forecast remains warm and dry, while the longer term continues to look very wet as the remnants of Barry move in our direction toward the end of the weekend. Today looks very much like Thursday, with clear to partly cloudy skies and warm but not terribly hot daytime temps. Dew points in the 60s will keep heat index numbers fairly close to actual air temps once again. This Friday evening should be quite pleasant with air temps falling through the 80s and mainly clear skies. Over the weekend we’ll start to warm up and become a bit more humid again….in fact a few isolated showers are possible by Saturday afternoon over our southern counties e.g. the Bootheel and NW Tennessee….and by Sunday we’ll likely be feeling the very outer edges of Barry moving in from the south.
Barry has finally begun to organize and strengthen a bit just south of Louisiana this morning. Dry air and northerly shear have been keeping it from spinning up very quickly, but now it looks as though it may become a Cat 1 hurricane later today before it moves ashore. But the main threat with Barry will be heavy rain….with flooding possible over the lower Mississippi Valley over the next couple of days. By Monday and into Tuesday the remnant low will be moving SW to NE across our region with clouds and rain and a threat of thunderstorms. Temps will be held down a bit but it will likely be very wet: some of our precip models are showing about 3 to 5 inches of rain during this period, especially over our southern counties. At some point flash flood watches may be issued for Monday and Tuesday, so stay tuned.
