Area Forecast Discussion National Weather Service Miami FL 131 PM EDT Mon Jul 22 2019 .AVIATION... Afternoon convection will be mainly over the interior and west coast this afternoon. Have removed VCTS from east coast sites but will still monitor activity moving west over the Atlantic from the Bahamas. Easterly winds this afternoon except for APF, with some occasional gust. Will continue to monitor convection from the Bahamas overnight for impact along the east coast. Included VCSH for now but confidence is low. L/V winds will becoming SSW tomorrow morning. && .PREV DISCUSSION... /issued 1019 AM EDT Mon Jul 22 2019/ UPDATE... Showers and thunderstorms are ongoing over the Atlantic and Gulf waters this morning. For the most part showers in the Atlantic have been dissipating before they reach the east coast metro. However, activity has begun to increase with models showing some of this activity reaching the east coast metro this afternoon. Deep moisture remains and continues to increase across the region with the latest 12Z MFL sounding having a precipitable water value of 1.93 inches, with model soundings having PWAT values rising above 2 inches. Convection will develop along the sea breeze and outflow boundary collisions over the interior and west coast. MLCAPE values will approach 3500 j/kg over the interior where strongest storms will be capable of producing some gusty downburst winds. The mid levels have warmed quite a bit with 500mb temps of 6C so hail is not as much of a concern today. The trough located over the Bahamas continues to move westward, which is helping to push convection over the Atlantic towards the east coast this afternoon. As the trough gets closer rain chances will remain elevated. Showers and storms will be capable of producing frequent lightning, gusty winds and heavy rainfall. Hi- res models show the bulk of the activity remaining over the Atlantic waters. However, a minor shift would put this activity over the east coast metro which may lead to higher rainfall rates and totals. This could lead to urban flooding concerns for low- lying areas along the east coast. This will be monitored as this trough progresses towards the region. Overall, increased rain chances as the trough moves towards the Florida peninsula today, overnight and into tomorrow. Only minor adjustments to the current forecast to account for current observations and the precip currently ongoing in the Atlantic. PREV DISCUSSION... /issued 242 AM EDT Mon Jul 22 2019/ DISCUSSION... Key Points: *A notable increase in shower and thunderstorm coverage is expected late tonight (Monday night) and especially into Tuesday, in association with a trough of low pressure approaching from the Central Bahamas vicinity. *As of 2AM EDT Monday, the National Hurricane Center indicates that there is a low chance -- i.e., 20 percent -- for cyclone formation to occur in association with the trough of low pressure during the next 2 days. *Regardless of development, the increased coverage of showers and thunderstorms will be accompanied by higher potential for frequent lightning, heavy rains capable of localized flooding, and strong wind gusts. The greatest chance for strong convective wind gusts will be on Tuesday and Wednesday. *While chances of showers and thunderstorms will continue into late this week and the upcoming weekend, present indications are that the coverage of this activity may be comparatively lower than earlier in the week. Technical Discussion: Today... Southeasterly to easterly flow in the lower/middle troposphere will persist today, along the eastern flank of a broad weakness in midlevel ridging -- between a midlevel anticyclone centered over the central Great Basin and a midlevel ridge extending westward from the central Atlantic. Large-scale ascent within this regime will be muted in the absence of any salient shortwave impulses tracking across the local area. However, ample deep moisture is already in place -- e.g., Sunday evening Miami observed sounding indicating around 1.94 inches of precipitable water. This moisture will be maintained by the southerly flow component in the low to midlevels. As a result, subtle mesoscale ascent will continue to foster a diurnal convective cycle similar to the last couple of days, with increasing shower and thunderstorm chances through the day -- focusing generally westward/northwestward over interior South Florida. Weak deep shear should generally limit convective organization. However, localized cold-pool amalgamation could facilitate a few instances of locally strong wind gusts toward the Gulf Coast vicinity later today -- aided by abundant precipitation-loading processes. Tonight through Tuesday night... The aforementioned trough of low pressure is forecast to be approaching the area from the east for tonight. The southerly flow component east of the trough axis will further reinforce an influx of deep tropical moisture into/across South Florida. As a result, a notable uptick in convective chances is anticipated over the South Florida Atlantic waters for tonight. Meanwhile, through the day today/Monday into tonight, a larger- scale midlevel trough over the eastern states is forecast to undergo amplification, as a speed maximum advances southeastward over the central states -- along the southwestern periphery of a deep cyclone centered over eastern Canada. Midlevel height falls accompanying the progression and amplification of the midlevel trough are forecast to be relegated to higher latitudes of the CONUS. However, the mass response peripheral to this evolving feature is expected to facilitate veering low/midlevel flow over the local area from late tonight into Tuesday -- establishing a zone of low to midlevel confluence between the aforementioned amplifying midlevel trough and persistent midlevel ridging well off the Atlantic coast. In response to these developments, the trough of low pressure could become absorbed northeastward/northward into the zone of confluence on Tuesday. The evolution of this pattern may tend to favor the plume of richest tropical moisture -- e.g., 2.0-2.3-inch precipitable water -- taking a track over the eastern half of South Florida and over the Atlantic waters -- where the highest precipitation chances exist for Tuesday and Tuesday night. However, there is still considerable uncertainty regarding the exact track of the trough of low pressure, and enhanced precipitation chances will exist across much of the area for Tuesday into Tuesday night. Regarding potential hazards, heavy rainfall is expected to accompany showers and thunderstorms from Monday night into Tuesday night, and localized flooding may become an increasing concern. This could especially become a concern across the east coast metro areas, if the confluence axis were to become established along or just inland from the east coast -- fostering a potential convective- training pattern inland, amid the richest tropical moisture. Moreover, given the potential for modestly enhanced low-level flow fields -- in proximity to the trough of low pressure -- to facilitate convective momentum transport, a risk for strong convective wind gusts may accompany this activity. Frequent lightning strikes will also be a potential hazard with this activity. Wednesday... Low to midlevel flow will continue to veer over the local area into Wednesday, as height falls accompanying the previously mentioned midlevel trough progress farther off the mid-Atlantic and New England coast. Meanwhile, beneath a zone of enhanced midlevel flow trailing farther southwest, the western extent of a trough- attendant frontal zone is forecast to stall over the northern Gulf and north Florida vicinity. The combination of broad/weak pre- frontal isentropic ascent -- locally enhanced by ageostrophic circulations accompanying minor speed maxima embedded in the enhanced midlevel flow -- and ample moisture already in place, will maintain convective chances. The greatest potential for showers and storms on Wednesday will be across northern portions of the NWS Miami County Warning Area in closer proximity to the synoptic boundary, and also where stronger low-level convergence is focused in proximity to the east-coast-vicinity sea-breeze boundary. Midlevel lapse rates should be modest in magnitude -- limiting parcel accelerations in updrafts. However, the presence of deep unidirectional/southwesterly flow, with 15 kt to locally 20 kt of 500-mb winds in closer proximity to the synoptic boundary, may support some convective organization and sustenance. Eastward and east-northeastward-moving convective clusters could produce locally strong wind gusts -- particularly where low-level lapse rates diurnally steepen the most. Heavy rain and frequent lightning will also be potential hazards with this activity. Localized flooding could occur, especially in areas that experience multiple occurrences of heavy precipitation through mid-week. Convection should principally become confined to the coastal waters by Wednesday night. Late this week into the upcoming weekend... For late this week into the upcoming weekend, medium-range model solutions indicate gradually rising midlevel heights over the southeast states, with a midlevel ridge building over the local area. This evolving pattern should tend to minimize prospects for larger-scale ascent to affect the area. However, the maintenance of rich deep-layer moisture will support shower and thunderstorm chances lingering into next weekend. Present indications are that the coverage of this activity may be comparatively less than that earlier in the week. Temperature concerns... Heat index readings could reach around 100 to 105 degrees each day, with the highest of these readings primarily expected across the western half of South Florida. As a result, caution is advised for those involved in outdoor activities owing to the potential for heat-related impacts. However, given the abundance of convective activity and related cold pools/cloud coverage, the overall potential for heat-related highlights is limited. MARINE... Generally east to southeast winds of 5 to 10 knots are expected to prevail over the coastal waters today, with winds turning more southerly on Tuesday and then southwesterly later in the week. Wind speeds are forecast to increase to 10 to 15 knots over the Atlantic waters late tonight into Tuesday. Wave heights are expected to generally range from 1 to 2 feet, with the potential for locally higher seas over the Atlantic waters around Tuesday and Wednesday. Shower and thunderstorm coverage is expected to increase for tonight into Tuesday, with this activity becoming numerous over the Atlantic waters on Tuesday. Shower and thunderstorm chances will continue through the remainder of the week. Lightning, locally gusty winds, and heavy rain should be the primary concerns with this activity. BEACH FORECAST... For the Atlantic coast, an onshore-flow component will support a non-zero rip-current risk for the Atlantic beaches today, especially for the beaches of Palm Beach and Broward Counties. However, generally weak surface winds should limit the overall rip-current potential. Otherwise, a chance for showers and thunderstorms capable of producing dangerous lightning, gusty winds, and heavy rain will be present for all Atlantic and Gulf beaches for today -- with these chances increasing tonight into Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
