Area Forecast Discussion National Weather Service Miami FL 244 PM EDT Sun May 31 2020

Short Term (Tonight through Monday Night). An upper level high will continue across the region. This will help keep mid levels a bit warm and will suppress convection development overall. Despite the weak high aloft, still expect some convection to develop with the stronger surface convergence (i.e. sea/gulf/lake breeze collision) across the interior and Gulf coast. CAMs have been performing very well lately with convection development (timing and coverage). They suggest convection should begin to develop across the Everglades around 18z and continue through around sunset. Considering the overall pattern hasn't changed much it is challenging to disagree with this solution.

Surface flow will begin to increase on Monday as a cold front begins to slide southward. Continued POPs across the interior and southwest Coast, however, QPF signal isn't as strong as previous forecasts. We will maintain POPs Monday through Monday night, but overall the best rainfall will be across the Gulf and perhaps the FL straits. In the increasing easterly flow wouldn't be surprised at a few Atlantic showers Monday night to finish off the short term.

Long Term.

Tuesday and Wednesday .

Upper troughing will locate from the Northeast States into the Canadian Maritimes as downstream ridging elongates over the Southeast States and Bahamas. Persistent low pressure will continue across the southern Gulf of Mexico and Bay of Campeche, as the remnants of Pacific Tropical Storm Amanda merge into this larger scale gyre. At the surface, a weak cold front will become increasing diffuse while pushing into South Florida. Atlantic subtropical ridging will establish to our northeast resulting in a tightening pressure gradient and breezy easterly wind regime. This will also set up a moisture gradient across the area, where the greatest precipitable water values (around 2 inches) stretch from far southeast Florida towards areas west of Lake Okeechobee and the Gulf coast. This suggests that the greatest rain and thunderstorm coverage should gradually transition from portions of the east coast during the morning towards the Gulf Coast and western interior regions during the afternoon and evening. A few stronger storms are possible, with the primary hazards being lightning, gusty winds, and torrential rainfall. Localized flooding is possible, especially for the western interior and Gulf coast areas.

Thursday through Sunday .

A consensus of the forecast models suggest that a large cyclonic circulation should lift north into the Gulf of Mexico and western Caribbean Sea during this time. Considerable differences remain regarding the strength and placement of this feature, leading to uncertainty in this low predictability scenario. There is a general consensus that deep moisture should increase across South Florida with precipitable water values nearing or exceeding 2 inches at times. While confidence is low, periods of heavy rainfall may evolve over some portion of our area by late week into the weekend. This is potentially problematic given the (very wet) antecedent conditions. Forecast changes are likely during this period so stay tuned for updates.

Marine. Favorable marine conditions expected to start the workweek, however, this will quickly change as a backdoor cold front begins to move southwest toward the region late Monday and early Tuesday. Cautionary headlines are expected, but small craft conditions are also possible, especially for the Atlantic. Some improvement is expected by midweek as pressure gradient relaxes as high pressure dominates the western Atlantic. Scattered showers and T'storms are expected off and on through the period. The stronger storms may contain gusty winds and locally higher seas.

Aviation (18z Aviation). VFR conditions will prevail for the south Florida terminals. There may be a rogue shower or two on the Atlantic coast, however, the better rain chances will be across interior south Florida this afternoon. APF is the exception. Today looks a bit drier than previous days around or near APF, however, late afternoon or early evening TSRA still can't be ruled out. Went with VCs for now. Convection clears overnight and winds lighten.

Beach Forecast. Southeast flow will continue this afternoon through the overnight. The rip current potential will overall be low for south Florida Beaches. Easterly winds will increase as we begin a new workweek with a gradual increase in rip current frequency.
