Area Forecast Discussion National Weather Service Jacksonville FL 1224pm EST Monday Jan 13 2025 .SHORT TERM... (Tuesday through Wednesday night) Issued at 142am EST Monday Jan 13 2025 Predominately northwesterly winds develop on Tuesday after a cold front's passage. Cold and dry air will advect into the region for through midweek as high pressure builds in from the northwest and finally be overhead by Thursday evening. Below normal temperatures are expected Tuesday through Thursday. Daytime highs in the mid 50s along SE GA locations and the upper 50s to lower 60s along NE FL locations. Colder air continues to filter into the region during the overnight hours. Coldest overnight temperatures will be along locations in SE GA and the Suwannee Valley Region of NE FL, as lows will be the upper 20s to lower 30s for each night from Tuesday to Thursday. The need for Frost and Freeze products for these three nigheights will be likely for SE GA and the Suwannee Valley Region of NE FL, with other locations of NE FL currently expected to be sitting just above freezing. Long Term (Thursday through Sunday) Issued at 142am EST Monday Jan 13 2025 The high pressure begins to shift off towards the Atlantic and with it, so do the below normal temperatures. A shift in winds to southerly-southwesterly will allow for warmer air to filter in and bring temperatures to near normal levels, in some locations to above normal on Friday. Showers make a return late Friday night into Sunday ahead of an approaching cold front. The warmer temperatures will continue Saturday and Sunday, with above normal temperatures expected on Saturday and near normal temperatures on Sunday. Current guidance suggests the cold front will be at our doorstep just to the northwest of the local area on Sunday. Marine Issued at 142am EST Monday Jan 13 2025 North to Northeast flow expected today in the 10 to 15 knot range as low pressure in the Eastern Gulf passes across Central FL and into the Atlantic to the south of the local waters tonight. Expect a more significant increase in the North winds close to SCA (Small Craft Advisory) levels after midnight across the NE FL waters and headlines may need to be posted, but since this appears marginal at this time and late in the second forecast period will likely let the day shift make final decision on SCA (Small Craft Advisory) headlines. Trailing frontal passages on Tuesday into Wednesday will continue at least SCEC level and likely SCA (Small Craft Advisory) type North to Northwest winds this period with headlines likely to continue. Cold high pressure ridge builds into the region on Thursday with decreasing Northwest winds and headlines will end with continued light winds into Friday as high pressure builds directly over the local waters. Models not quite in agreement for next weekend, but overall south to southwest winds expected to increase to SCA (Small Craft Advisory) levels on Saturday ahead of the next low pressure and frontal system. Rip Currents Generally low risk of rip currents continues at local beaches despite the low level flow becoming NE today, but generally at light wind speeds, then becoming North at stronger speeds on Tuesday, but overall surf/breakers will remain around 2 feet or less early this week.
