Area Forecast Discussion National Weather Service Tallahassee FL 1042am EDT Sat April 26 2025 ...New Issued at 1040am EDT Sat April 26 2025 The morning fog has finally mixed out for the most part. Temperature trends have been adjusted to account for the lingering cloud cover this morning, but overall high temperatures were unchanged. All other aspects of the forecast remain on track this morning. Near Term (Today and tonight) Issued at 327am EDT Sat April 26 2025 Isolated showers and thunderstorms are possible this afternoon and evening, mainly over the inland FL Panhandle, Southeast Alabama, and Southwest Georgia to the west of the Flint Valley. A surface trough and wind shift is currently making its way south through the Mid-South region. It will arrive over the Alabama Wiregrass later this afternoon. Low-level convergence will be further aided as it joins forces with the Panhandle seabreeze front. This would support isolated showers and thunderstorms during the late afternoon and early evening hours. Limiting factors will be Precipitable Water (PW) values well under 1.5 inches, only weak or locally moderate convective instability, and anemic deep-layer shear of only 10-15 knots. So any convection that does develop will be the short-lived pulse variety and on the weaker side. The other interest will be early morning fog this morning, and again during the early morning hours on Sunday morning. A small bubble of surface high pressure over the far northeast Gulf will support a healthy Panhandle seabreeze, advecting a shallow layer of 65-70F dewpoints onshore. As of 3 am CT, we are already seeing dense fog along the I-10 corridor from Bonifay westward, and a Dense Fog Advisory is in effect until after sunrise for the inland Panhandle and parts of Southeast Alabama. A near- repeat is possible in the same general areas on Sunday morning. .SHORT TERM... (Sunday through Monday night) Issued at 327am EDT Sat April 26 2025 Afternoon and evening thunderstorms, along with hot temperatures are the main concerns. The shortwave trough over the southern High Plains of New Mexico and West Texas will move east, with its reflection passing across the Southeast States on Sunday. Weak height falls will pass across Georgia during peak afternoon heating, gently eroding the mid- level cap of warm and dry air. A washed out and diffuse frontal boundary will add some low-level focus over the Alabama and Georgia Wiregrass regions, and the seabreeze front will add further focus. PW values (Precipitable Water values) will moisten a little compared with Saturday, though remaining below 1.5 inches. Deep-layer shear will increase into the 20-25 knot range. So isolated to perhaps scattered afternoon and evening convection will affect a greater area on Sunday, encompassing more of the inland FL Big Bend and southwest Georgia, compared with today. On Monday, a 500 mb ridge axis will amplify over the Lower Mississippi Valley, with a downstream turn to northwest flow aloft. Fairly strong surface high pressure will emerge off the Delmarva coast, forcing a back door cold front to move inland from the Atlantic. This will really enhance the Atlantic seabreeze on Monday afternoon and sharpen the low-level focus along the I-75 corridor and Suwannee Valley,, where scattered convection is forecast on Monday afternoon and evening. Long Term (Tuesday through Friday) Issued at 327am EDT Sat April 26 2025 The back door cold front will hang up along the I-75 corridor on Tuesday and lose definition, as the 500 mb ridge axis over the Lower Mississippi Valley expands across the northeast Gulf. This will diminish coverage ofpm convection. By Wednesday, the lack of low-level focus and a renewed cap of warm dry air aloft will eliminate convective opportunity, while maintaining well above normal daytime temperatures. Thursday and Friday will see an upper-level longwave trough slowly ambling across the eastern U.S.. Westerly flow aloft will increase across our region, and lowering upper heigheights will erode the cap of warm dry air aloft. Cyclonic flow aloft in the base of the longwave trough could contribute to some deeper-layer lift, while pushing a cold front south through Alabama and Georgia on Friday. All of these factors will support a day-to-day increase in convective coverage on Thursday and especially Friday. Marine Issued at 327am EDT Sat April 26 2025 A bubble of high pressure will reside over the far northeast Gulf through Monday afternoon, making the nearshore afternoon seabreeze the main driver of wind. Stronger high pressure will move from the Delmarva region toward Bermuda from Monday night through Wednesday, bringing a turn to easterly flow. Moderate to possibly fresh nocturnal surges are expected on Tuesday and Wednesday nights. Fire Weather Issued at 327am EDT Sat April 26 2025 The main fire weather concerns through Monday will be with a growing coverage of afternoon thunderstorms each day, and well above normal temperatures. Any thunderstorms today will be on the weak side and confined near the Panhandle seabreeze. Seabreeze activity will increase on Sunday and encompass more of the Big Bend region. On Monday, a back door cold front will push in from the Atlantic toward the I-75 corridor and Suwannee Valley, providing a focus for afternoon and evening thunderstorms. Otherwise, areas of early morning fog are expected, especially over our Florida Panhandle districts. Hydrology Issued at 327am EDT Sat April 26 2025 No flooding is expected for the next 7 days.
