Update

Issued at 730 AM EDT Thu Oct 22 2026

Low-level trough just north of the Bahamas, embedded in the general N-NE wind flow, is skirting the Florida east coast this morning and helping to trigger scattered showers along and offshore the Palm Beach County coast. Hi-res/short range models are handling this scenario fairly well, and depict a southward spread of the showers mainly over the nearshore Atlantic waters but skirting the east coast metro from time to time through much of the day. Current forecast PoPs are handling this well so no changes needed to the forecast at this time except to increase cloud cover southward along the east coast this morning.

NOS tide gauges are peaking in the minor flood stage at the current high tide, except bordering on moderate at Lake Worth Pier. These levels continue slightly above guidance, so current expectation of moderate flood levels with upcoming high tides over the next several days is on track.

Short Term

(Today through Friday) Issued at 106 AM EDT Thu Oct 22 2026

Latest surface analysis shows high pressure over the TN Valley, and Subtropical Storm Josephine off the New England coast. At the upper levels, the ridge over the center of the country continues to nose eastward and a trough is slowly deepening over the eastern third of the country. Latest 00Z sounding shows plenty of dry air at the mid and upper levels, with some low level moisture to support widely scattered coastal showers today. Winds will continue to be out of the NNE and gusting to around 20-25 mph this afternoon. High temps will be in the low to middle 80s. Scattered coastal showers will continue overnight with mainly dry conditions over the interior and SW FL. Overnight lows will be comfortable ranging from the low to mid 60s around the lake region, the lower 70s closer to the coast.

As the trough continues to deepen on Friday and an upper low starts to develop off the SE US coast late in the day, low level moisture will start to increase with PWAT values nosing up to around 1.5 inches. Forecast soundings still show plenty of dry air aloft, but the shower activity should be more increased across the east coast metro compared to the past several days.

Long Term

(Friday night through Wednesday) Issued at 106 AM EDT Thu Oct 22 2026

As we head into the weekend and into early next week, a multi hazard event will be taking shape as an upper level low lingers in the region and strong surface high pressure builds into the eastern US. Enhanced moisture around the upper low will bring rounds of showers, heavy at times, to SE FL from Saturday through Monday. While mean QPF values have trended downward the past several days, 1-3 inches is still expected across the east coast metro, with localized higher end amounts of 4-6 inches possible. This rain combined with the higher king tides this weekend may present some flooding issues. WPC has a Slight risk of excessive rain across the metro both days this weekend. The other main story will be the gusty winds this weekend as the pressure gradient tightens. NE winds will gust 25-35 mph on Saturday and 30-40 mph on Sunday.

Conditions begin to improve Tuesday into mid week as the upper low pulls away from the region to the northeast and with it the deeper moisture will exit the area. There will still be scattered coastal showers around both days, but the rainfall flooding threat will decrease.

Fairly comfortable temperatures are expected this weekend into next week with high temps generally in the low to middle 80s, and low temps each day in the 60s/70s.
