| Area Forecast Discussion National Weather Service Key West FL 140pm EST Sunday Jan 16 2022 The squall line pushed thorugh the Florida Keys this morning without much fanfare. Multiple gusts in the neighborhood of 35 knots plus were noticed, but overall the line was well behaved. A few strong discrete cells developed in advance of the line over Florida Bay, but are in the process of being overtaken by the Squall line. The cold front is just beginning to enter the Florida Keys Gulf waters, and will likely sweep through by this afternoon. Thereafter, winds will veer from the west to northwest and remain above or near small craft advisory through the evening and overnight before decreasing tomorrow morning. Post frontal, much drier and cooler air will filter over the islands and coastal waters, which will effectively end any precipitation chances through at least thursday of next weeks. Tuesday morning will likely be the bottom, with low temperatures ranging from the mid 50s to around 60, with colder temperatures advecting off the mainland possible dropping the upper Keys a little lower. Too early yet to make that distinction in the forecast package. Tuesday morning, surface ridging building in behind the trough will move over the southeast CONUS, which will begin to veer winds to east of north, and then to the east by Wednesday as the ridge moves off into the Atlantic off the southeast coast. Therefore, by Wednesday morning low temperatures will begin to creep upwards into Friday. In the Friday/Saturday timeframe, the GSMs are generally showing another front moving through the Gulf and Florida Keys. The agreement is not there at this time to add any specificity to the longer range forecast, but it appears a weak front may bridge over the area on Friday to Saturday, as Gulf low develops and pushes a stronger front through the area on Sunday into Monday night. Marine A small craft advisory is in effect for all Florida Keys coastal waters likely through this evening and overnight. Strong west to northeast winds are expected behind the cold front currently moving through the islands and coastal waters, and should remain strong out of the northwest overnight. By tomorrow afternoon, winds will begin to slowly decrease out of the northwest becoming more moderate to fresh. As the week progresses, winds will slowly clock from northwest to northeast into Tuesday evening, and out of the east by Wednesday morning. No precipitation is expected after this evening through at least Friday.
