Area Forecast Discussion National Weather Service Miami FL 1225 PM EST Wed Feb 24 2021

AVIATION(18Z TAFS). Frontal boundary stalled across the area will spur a challenging next 6 to 8 hours with oscillating conditions between VFR, MVFR, and IFR due to slow moving, nearly stationary, vicinity SHRA. Features are so microscale that models cannot depict where and when SHRA could impact terminals, thus leaving VCSH for now with short-fused AMDs likely necessary, especially during the afternoon hours (around 19 to 23Z). Mostly ESE winds today, except for APF which will be SW due to Gulf Breeze, with light winds overnight. Fog potential also there but mainly in interior so omitted from terminals for now. Tricky wind forecast yet again tomorrow, though a predominant E wind looks to be the case again.

PREV DISCUSSION. (Issued 909 AM EST Wed Feb 24 2021)

UPDATE . A few changes to the forecast this morning. Latest TAFB surface analysis depicts a stationary boundary draped across the area. This combined with ample low-level moisture has allowed showers to develop and drift over the east coast metro, most notably showers in Miami Beach and near Pompano Beach have produced around a inch of rain this morning. Others showers are also developing along the boundary and drift around with little movement. Looking at the 12z MFL sounding you can see the that there is little to no wind or storm motion in the effect layer. These showers are all fairly low topped given the drier air once you get above the 750mb level. The drier air and weak lapse rates of 5.5C/km will help keep these showers shallow in nature and help to limit any thunderstorm potential today.

With that said, continued development of scattered showers across the region today as we have the low-level moisture and boundary to help with initial lift. As we do get into the afternoon a little more diurnal heating will allow for a little more coverage over the interior and the east coast through the afternoon and evening. With the slow storm motion, there may be very isolated areas where flooding may be possible of low-lying poor drainage areas. Therefore, this slight chance of flooding has been introduced into the HWO.

PREV DISCUSSION . (Issued 628 AM EST Wed Feb 24 2021)

AVIATION(12Z TAFS) . Frontal boundary across the area with mainly prevailing VFR conditions. Some showers with VCSH will bring brief periods of MVFR cigs/vis. Winds will gradually veer to southeast throughout the afternoon, except for APF will become westerly with a gulf breeze around 17Z. Light winds overnight. Fog potential will be possible mainly over the interior and left out of the terminals for now.

PREV DISCUSSION . (Issued 304 AM EST Wed Feb 24 2021)

SHORT TERM (Now through Friday) . A decaying cold front continues to drift southwards across the extreme Southern Florida Peninsula this morning. Meanwhile, A ridge of high pressure is established aloft across South Florida, which has largely resulted in benign and quiet conditions during the overnight hours. As an easterly flow continues to advect moist air as well as diurnal heating after sunrise, there is a slight chance of showers along the atlantic coast as the day progresses. Aside from a few brief passing showers from time to time, a relatively quiet day is expected. High temperatures today will range from the upper 70s along the Atlantic coast, to the low to mid 80s across the Gulf coast and Lake Okeechobee region, and in the mid 80s across portions of the western interior.

Precipitation chances begin to decrease on Thursday as dry air moves into the region in the wake of the frontal passage and as high pressure remains in firm control. A gradual warming trend will continue on Thursday, as maximum temperatures continue on the increase.

LONG TERM (Friday through Tuesday) . The remnant front will remain fairly close to our region before dissipating, however, with only limited lift early Friday, expect only isolated showers mainly off the Atlantic coast. Otherwise, aloft an impressive H5 ridge will continue to drive our overall weather across south Florida. This high situated across the southern Gulf and western portions of the Caribbean will allow for a progressive/zonal flow across the southeast United States. With the storm track well to our north, expect mostly dry conditions, however, low topped convective showers may be possible where the best boundary layer moisture manifest (generally close to the Gulf Stream) within the surface southerly or southeasterly flow regime. Otherwise, subsidence aloft will dry things above the boundary layer and with strong insolation across interior south Florida later this week and into the weekend, drier air will likely mix down. With the drying there could be at least a modest fire weather threat as relative humidity values drop into the 40 to 50 percent range.

The high aloft will persist, but begin to flatten later this weekend and early next week as a weak shortwave attempts to amplify over the Lower Mississippi River Valley and central Gulf Coast. Globals show the front move through the region sometime Tuesday or just beyond as the wave continues to amplify across the western Atlantic. At this range the confidence is somewhat on the low side. For now it is worth mentioning the possibility of a FROPA, but with run to run differences, will take a wait and see approach and allow a few more runs to solidify confidence before buying into this solution. Outside of that, above climo temps expected with some places across the interior reaching the 90 degree mark later this week and into the weekend.

MARINE . A frontal boundary remains draped across the extreme Southern Florida Peninsula and adjacent waters this morning. This boundary may allow for showers to develop across area waters during the morning and afternoon hours of today. As dry air filters in behind the frontal passage and high pressure continues to build over our area, benign and quiet boating conditions can be expected for all area waters through the remainder of this week.

BEACHES . There is a high risk of rip currents for Palm Beach county beaches. There is a moderate risk of rip currents for Broward county beaches. With marine conditions subsiding in the wake of the frontal passage, elevated rip current conditions may subside by the end of this week.
