Area Forecast Discussion . UPDATED National Weather Service Miami FL 1012 AM EDT Sat Apr 4 2020

Update. Generally dry and sunny start to this Saturday. Temperatures will be on the warm side today with much of the area reaching into the mid to upper 80s with some portions of the interior reaching into the lower 90s. Light synoptic scale wind flow will allow for any sea breezes that develop to dominate the pattern and the available moisture could allow for a shower or two to pop up along the sea breezes. Today's forecast appears to be on track with no additional updates anticipated through midday.

Sunday is trending wetter with northwesterly flow aloft, increasing low level moisture advection, and an approaching lower to mid level disturbance from the Gulf of Mexico. The disturbance is particularly discernible at the 700 mb level Sunday afternoon into early Monday morning. While forecast updates normally focus on the immediate period or two, felt the forecast trend for Sunday and Sunday Night necessitate an update now with additional analysis in the afternoon package later today. Updated zones have been transmitted with higher rain chances.

Prev Discussion. /issued 736 AM EDT Sat Apr 4 2020/

Aviation . Generally VFR with light onshore flow due to sea breezes. Some isolated showers cannot be ruled out around the sea breeze. Increasing cloud cover overnight into Sunday.

Prev Discussion . /issued 327 AM EDT Sat Apr 4 2020/

Short Term (Through Sunday Night) . High pressure will remain over the Western Atlantic waters this weekend keeping an easterly wind flow over South Florida. There will also be a low level short wave moving eastward from the Gulf of Mexico through the Florida Peninsula on Sunday. This low level short wave will bring in some low level moisture to the region starting late this afternoon into Sunday. There could be one or two showers late this afternoon over the interior areas where the sea breezes collide. The better chance of showers will be Sunday afternoon with the passage of the short wave especially around the Lake Okeechobee region due to the interaction of the sea breezes and the lake breeze. However, the POPs will still remain in the 20 percent range on Sunday afternoon except 30 percent around the Lake Okeechobee region.

Highs today will be in the 80s over most of South Florida except near 90 over the western interior areas. Highs on Sunday will be a little cooler due to more cloud cover, but still will be in the lower to mid 80s, except around 80 east coast metro areas. Lows tonight and again Sunday night will be in the 60s, except around 70 east coast metro areas.

Long Term (Monday through Friday) . Easterly flow to start the week will gradually become westerly by Wednesday as surface high pressure off the SE CONUS coast slides southward and settles over Cuba. A slight chance of rainfall is possible on Monday as both seabreezes may generate some showers and perhaps a thunderstorm or two. Otherwise the long term looks mostly dry with a couple of cold fronts stalling out to our north over North Florida.

Increased cloud cover on Monday will keep high temperatures in the upper 70s to mid 80s, but a warming trend is expected with highs reaching the upper 80s to low/mid 90s by Thursday into Friday. How warm we end up getting plus any low-end shower potential could vary day to day depending on how close the mid/upper ridge over the southern Gulf slides towards South Florida. Models diverge at the tail end of the forecast period with the GFS bringing a front all the way through the state sometime Friday into Saturday, while the ECMWF stalls it further north. Trended towards the ECMWF for now, but it bears watching for future forecast packages.

Marine . Generally benign marine conditions are expected today before northeasterly swell increases waves for the Atlantic waters starting early Sunday morning. A Small Craft Advisory could be needed as early as Sunday morning, particularly for the Gulf Stream. Waves remain elevated for a few days before subsiding around midweek.

Beach Forecast . The threat of rip currents will continue along the east coast beaches of South Florida this weekend due to the northeast swells affecting the Atlantic waters. Therefore, the High Risk of Rip Currents will continue for the beaches of Palm Beach County through this weekend with a Moderate Risk of Rip Currents rest of the east coast beaches.

Fire Weather . The relative humidity over the western interior areas of South Florida could fall down to near critical values for couple of hours this afternoon. However, the 20 foot winds will remain below 15 mph. Therefore, no fire weather headlines will be needed for South Florida for today.

Preliminary Point Temps/PoPs. West Palm Beach 85 68 81 68 / 10 10 40 30 Fort Lauderdale 83 70 82 70 / 10 10 30 30 Miami 84 70 83 70 / 10 10 30 30 Naples 84 67 81 67 / 0 10 30 20

MFL WATCHES/WARNINGS/ADVISORIES. FL . High Rip Current Risk through Sunday evening for FLZ168.
