National Weather Service Jacksonville FL 737 AM EDT Sat May 17 2025 ...New AVIATION... .SYNOPSIS... Issued at 354 AM EDT Sat May 17 2025 Overnight surface analysis depicts Atlantic high pressure extending its axis westward across the FL peninsula and the southeastern Gulf. Meanwhile, pair of cold fronts extend southwestward from strong low pressure (990 millibars) that was migrating across the Great Lakes region, with these boundaries pushing across the Upper Midwest and approaching the Ohio, Tennessee, and lower Mississippi Valleys. Aloft...deep-layered ridging that extends across the Gulf and the FL peninsula was flattening as deep troughing migrates across the Great Lakes states, with a 120 knot jet streak positioned around 250 millibars (around 35,000 feet) migrating across the Ozarks and the Tennessee Valley in between these features that was fueling a severe weather outbreak across the lower Mississippi and Tennessee Valleys. Latest derived Total Precipitable Water imagery indicates that a dry and subsident air mass prevails locally, with PWATs of only around 1 inch at most locations. Brisk northwesterly flow above 500 millibars (around 25,000 feet) located on the periphery of the ridge over the Gulf was advecting thin cirrus into our region, with thicker cirrostratus located upstream across the Deep South. A west-southwesterly breeze was keeping temperatures in the upper 60s and lower 70s at most locations as of 07Z, with dewpoints mostly in the low and middle 60s.
