Small Craft Advisory Conditions Friday Night
Patchy Frost Expected Across Inland SE GA and Suwannee Valley on Sunday Morning
Increasing Marine and Coastal Hazards Next Week. Gale Force Winds, Gusty Northeast Winds, and High Rip Current
Cooler and Drier Friday Following Frontal Passage
Another cold front will push across the area on Friday, clearing south of the area by Friday Night, with high pressure building towards the southeastern US on Saturday. Temperatures Friday will be cooler, highs only reaching the 60s for most of the area, near 70 for the north central Florida area. Breezier northwesterly winds continue, with clearing skies throughout the day. A steep drop in low temperatures is forecast, with lows falling into the upper 30s for inland southeast Georgia and the Suwannee valley, lower to mid 40s elsewhere, not quite cold enough for frost yet.
Colder and Drier Conditions this the Weekend Wind Chills Drop into the 30s Saturday and Sunday Mornings. Inland Frost Potential for Southeast GA and the Suwannee Valley Early on Sunday Morning.
Surface high pressure over the northern MS river valley strengthens as it builds southeastward this weekend. Breezy NNW flow will continue to funnel cold, dry air across the region. Despite plenty of sunshine, highs will only rise into the upper 50s to low 60s on Saturday. Winds decrease Saturday night allowing for winds to decouple and radiational cooling to take hold. Lows Saturday night into Sunday morning will likely fall to the mid and upper 30s across inland SE GA and Suwannee Valley, with the potential for near freezing temperatures for areas north of Alma. This set-up will likely create the first frost of the season with patchy to areas of frost across inland SE GA and Suwannee Valley. Lows elsewhere will fall to the 40s. On Sunday, strong high pressure begins to wedge down the southeastward seaboard developing northeast flow. With the flow shifting to onshore, temperatures will begin to gradually bounce back. Highs on Sunday will remain in the 60s, except lower 70s for portions of north central FL. Sunday night lows will range from the upper 30s and 40s inland to the 50s closer to the coast.
Seasonably Cool and Dry Weather into Early Next Week. Increasing Coastal and Marine Hazards Forecast Next Week.
Breezy northeast flow develops next week as strong high pressure builds into the mid-Atlantic region and wedges down the southeastern seaboard. In the upper levels, a shortwave trough passes across the SE US early next week and could potentially develop a weak surface low in the Gulf and track across south FL but there still remains a bit of uncertainty. The development of this low could tighten the local gradient leading to potential windy conditions mid-week next week. Showers return to mainly coastal locations on Tuesday and Wednesday with an influx in low-level moisture from the onshore flow and assistance from the passing upper shortwaves. The prolonged onshore flow will cause temperatures to warm to seasonable by the latter half of the week.
