Area Forecast Discussion National Weather Service Jacksonville FL 301 PM EST Wed Jan 4 2023 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... (Through Tonight) Issued at 242 PM EST Wed Jan 4 2023 Prefrontal line of convection will continue to move east across the area over the next few hours. This line remains favorable for severe storms, with a few tornadoes possible. The cold front itself lags behind the line, and will move southeast across the area Overnight. While a few showers are possible on the front, the main area of convection will push east this afternoon with the prefrontal trough line. Lows Tonight will range from the mid 50s inland SE GA, to the mid 60s coastal NE FL. && .SHORT TERM... (Thursday through Sunday) Issued at 242 PM EST Wed Jan 4 2023 A few showers and storms will linger on the front as it passes to the southeast Thursday morning. High pressure will build from the west through the afternoon, with skies clearing. Highs on Thursday in the lower to mid 70s. For Thursday night into Friday, the high will continue to build closer to the region from the northwest. This will yield mainly clear skies, with cold advection bringing in cooler temperatures.
