Area Forecast Discussion National Weather Service Miami FL 333 PM EST Sat Jan 25 2020

Short Term (Through Sunday Night). A cold front continues to push through the region today. While mainly a dry front there are a few showers possible over the Atlantic waters and southern portions of the region before the front finally passes and moves offshore. Outside of an isolated shower otherwise seasonable temperatures in the mid to upper 70s today across South Florida.

Winds become more northerly behind the front allowing for some cooler and drier air to filter down the peninsula. Overnight lows will range from the low 40s around the Lake region, to mid to upper 40s across the interior, low to mid 50s across the metro and upper 50s near the coast.

High pressure builds over the northern Gulf behind the FROPA with sunny and clear skies on Sunday. This will allow for seasonable, benign weather to end the weekend with highs in the low to mid 70s.

Long Term (Monday through Friday Night). Broad troughing over the eastern half of the CONUS continues into the work week with a small shortwave over the Gulf helping push a weak Gulf low eastward towards the state as a separate fold front pushes southeastward through the Southeast US. Both the shortwave and the surface low weaken considerably as they approach the Florida West Coast on Monday, with the approaching cold front helping clear everything out Monday night into Tuesday.

While the cold front is pushing through our area, troughing over the far southern Plains induces another surface low over Texas that pushes into the Gulf and begins to make its way towards our area. Upper level support for this system weakens considerably as it pushes across the state Wednesday night into Thursday, with most of the rainfall expected to remain to the north of our area over Central and North Florida.

Late in the week, deep troughing over the western CONUS extending down into Mexico winds southeastward towards the Gulf, developing another surface low over the northwestern Gulf on Friday. This system will be the one to watch as it retains significantly more mid and upper level support as it pushes eastward across the Gulf and towards the state. If this system keeps its spunk as it pushes through the area early next weekend, any interests with outdoor activities or games will want to closely monitor the forecast.

Marine. Light northerly winds as a cold front passes through the region with only some scattered showers possible over the Atlantic waters for the remainder of the day. A 2 foot swell continues in the northern Atlantic waters allowing for wave heights to be generally 2 to 4 feet, with highest seas occurring in the northern Atlantic waters and Gulf stream.

Aviation. Prevailing dry and VFR conditions throughout the period. There have been brief patchy MVFR cigs, but going with SCT low level clouds as vis satellite trends show breaking of clouds. Northwesterly winds the rest of the afternoon and evening, with L/V winds overnight.

Beach Forecast. A 2 foot swell continues to affect the Atlantic waters offshore Palm Beach today and lingering into tomorrow. This will lead to a high risk of rip currents along Palm Beach County beaches through the weekend.

Fire Weather. Drier air will filter down the peninsula behind a cold front moving through the area today. This will cause Min RH values to drop into the upper 20s to low 30s over the interior and west coast leading to enhanced fire weather conditions Sunday. However, wind critical thresholds are not expected to be met.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
