TALLAHASSEE, Fla. (WCTV) - The threat of severe weather will linger in some locations into Wednesday as another storm system develops is forecast to move through the Big Bend and South Georgia.
The Storm Prediction Center placed most of the viewing area under a level 1 out of 5 threat of severe weather for Tuesday with damaging winds and an isolated tornado being the primary threats. The SPC also placed most of South Georgia under a level 1 threat Wednesday.
A line of showers and storms was moving through South Georgia and the western Big Bend around 4 p.m. Tuesday. The strongest storms were located over southern Liberty County into Gulf County. A Special Marine Warning was issued for the coastal waters from near Panama City to near Apalachicola and was set to expire at 6 p.m.. The easterly-moving line was forecast to move through the rest of the viewing area Tuesday evening. Convection-allowing forecast models have the squall line decreasing in intensity around and after dusk as atmospheric energy decreases.
A second trough of low pressure aloft is forecast to move through the Southeast, but stay reasonably far north of the viewing area as a ridge of high pressure keeps it farther north. Regardless, some of the energy associated with the trough will help develop a surface low and a cold front and push it into the viewing area on Wednesday. This front will pass through the area during the afternoon and evening Wednesday, but showers and storms are forecast to move through ahead of that.
A potential of higher wind speeds just under a mile above the surface along with decent wind shear, lingering deep moisture and above-normal temperatures will keep the threat of stronger thunderstorms with a low-end potential of damaging winds and an isolated tornado in the forecast Wednesday.
The Pinpoint Weather Team will continue to monitor the progress of the threat. Be sure to download the WCTV Pinpoint Weather app to access the radar, forecasts, and receive watches and warnings if and when they are issued.
TALLAHASSEE, Fla. (WCTV) - An approaching cold front will help to bring a good chance of showers and thunderstorms Tuesday, along with a threat of damaging winds and an isolated tornado.
The Storm Prediction Center placed most of the South Georgia viewing area and the western Big Bend under a level 1 out of 5 (marginal) risk of severe weather for Tuesday.
An approaching cold front is forecast to stall just to the north of the Big Bend Tuesday as it runs into a ridge of high pressure and prevent further movement. Most of the mid-level energy was well to the north Tuesday, but abnormally-high moisture content for late January along with upper-level difluence noted on the Tuesday morning upper-air maps (which aids in lift), the cold front, and sufficient wind shear will provide a low-grade risk of severe weather.
The squall line was located from Colquitt southwestward to Marianna to Santa Rosa Beach as of 10:40 a.m. Tuesday. Convection-allowing models show this line slowly pushing eastward through the rest of the day. Some of the in-house guidance models hint at the line falling apart, but the High-Resolution Rapid Refresh model is a bit more aggressive with its intensity as it pushes into more South Georgia counties in the afternoon and the Big Bend in the late afternoon to evening.
The squall line could impact the drive home from work.
The Pinpoint Weather Team will continue to monitor the progress of this line of showers and storms. Be sure to download the WCTV Pinpoint Weather app to access the radar, forecasts, and receive watches and warnings if and when they are issued.
