Area Forecast Discussion National Weather Service Key West FL 947pm EST Sunday Jan 26 2020 Clear skies and dry conditions prevail across the Florida Keys on this Sunday evening, with satellite imagery showing only some low clouds over the eastern Straits of Florida, along with wispy cirrus passing by to our north. Radar depicts no precipitation across the service area. The clear skies combined with very light winds and relatively low dewpoints in the 50s have allowed for excellent radiational cooling during the evening, with the RAWS site at North Big Pine dropping all the way down to 51 degrees already, and a few other interior sites in the Lower Keys such as Sugarloaf Shores and the NWS office here in midtown Key West dropping into the mid to upper 50s. Elsewhere across the Keys, current temperatures range from around 60 to the mid 60s. Surface analysis depicts weak high pressure over the eastern Gulf of Mexico and the Florida peninsula, with a weak low pressure area and associated cold front over the western Gulf. The 00Z Key West sounding sampled a very dry airmass in the wake of the previous front that moved through the Keys on Saturday, with a strong inversion based below 1000 feet, and very low PW value of 0.51 inches, which is below the 10th percentile for this date. Overnight, clear skies may give way to some high clouds streaming in from the west late tonight, but the very dry airmass in place will continue to prevent any rainfall. The only forecast issue will be low temperatures, as continued good radiational cooling allows temps to approach or reach slowly rising dewpoints. Have updated the public forecasts to open up more of a range for overnight lows, mainly in the interior portions of the Lower Keys, based on current observations. No other updates are planned for this evening. Marine Evening observations show benign conditions across the Keys waters, with mostly northerly breezes of less than 10 knots prevailing. Light winds are expected to continue overnight, and no significant changes are planned for the late evening forecast issuance. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
