Area Forecast Discussion National Weather Service Miami FL 402 PM EDT Mon Jul 16 2018 .DISCUSSION... Today-tonight: Scattered to numerous thunderstorms this afternoon will drift northward, so highest concentration of late afternoon/early evening storms will be over the northern half of South Florida. A few storms have been strong so far this afternoon. The activity over land should wane during the evening hours. Tuesday through Thursday night and possibly lasting into Saturday, we will see a large scale weather pattern that is characterized by troughs of low pressure and stormy weather over the southeastern U.S., northern Florida, and possibly as far south as central Florida. However, a strengthening subtropical high nosing its way into South Florida is likely to prevent the enhanced storminess from reaching the southernmost portions of the Florida Peninsula for much of the week. At the same time, dry mid-level air from the Saharan Air Layer is likely to affect South Florida beginning sometime around late Tuesday and lasting for much of the remainder of the work week. Layered precipitable water imagery from CIRA shows that the dry air is most pronounced at the 500-700 mb level and is currently approaching the Bahamas from the east-southeast. There will likely be some breaks in the SAL this week, and there could be a point in time later in the week when the trough moves a little farther south. But for now, expect rain chances to be somewhat lower on Tuesday through Thursday compared to Monday for much of South Florida. During this time, PWATs will be much higher over northern Florida compared to South FL due to the trough. Low-mid level steering will be from the southwest much of the week, so any mid-afternoon storms that form would move toward the northeastern part of South FL for late afternoon. Heat index values Tuesday and and Wednesday are forecast to be as high as 104-106 for the western half of Collier County, Mainland Monroe and inland Miami-Dade over the Everglades. Heat index values are also forecast to reach 104-106 for portions of metro Palm Beach County Tuesday and Wednesday. Friday-Sunday forecast will depend on how much and how quickly the ridge breaks down, if at all. There is still significant uncertainty as to if and when the trough to our north will move southward. The ridge could hold through day 7, which would keep us in a similar weather pattern. However, as time goes on, from day 5 to day 7, it appears that the chance of the ridge breaking down will gradually increase. This means that moisture and PoPs could increase over the weekend. && .MARINE... The western Atlantic ridge will build westward through the week, with the axis generally draped across South Florida and the adjacent waters. Prevailing flow will remain southerly through Tuesday, then southwesterly late week as a frontal boundary drifts into the FL peninsula. The increasing pressure gradient will bring speeds up to 10 knots over the Gulf and 10-15 knots over the Atlantic, still light enough to allow both the Gulf and Atlantic seabreezes to develop each afternoon. Seas generally 2 ft or less, occasionally 3 feet in the Atlantic. Showers and storms will be a concern for all the waters through the period, though coverage should generally be below normal. Locally higher winds and seas are possible near any storms. && .AVIATION... Convection has developed along the sea breeze boundaries this afternoon, which are mainly inland of the terminals. TMB and FXE could see an impact if a storm were to backbuild. Otherwise, any remnant convection that remains as the sea breezes retreat could near the terminals. A drier day possible on Tuesday with confidence not high enough to include any mention of convective impacts at this time. && .PRELIMINARY POINT TEMPS/POPS...

This hazardous weather outlook is for South Florida. .DAY ONE...TODAY AND TONIGHT Thunderstorms: Scattered to numerous thunderstorms are expected to develop this afternoon over the interior. Isolated activity will be possible elsewhere, except scattered over the western east coast metro areas this afternoon. The main threats should consist of heavy rain, cloud to ground lightning strikes, and brief gusty winds. Flooding: Heavy rainfall from thunderstorms this afternoon into early evening could lead to ponding or localize flooding in poorly drainage areas. Wind: Thunderstorms will be capable of producing winds up to around 50 mph. Temperature: Heat index values will rise to 100 to 105 degrees across most of South Florida today. Waterspout: Isolated waterspout activity will be possible today over all coast waters. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY Isolated to scattered thunderstorms are forecast for the remainder of the week each afternoon and early evening over the interior region. Lightning will be the main hazard. High temperatures may rise a few degrees above normal in the low to mid 90s through mid-week, potentially bringing several hours of heat indices in the 102F to 107F range during the late morning and early afternoon for the southern interior and Gulf Coast regions. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time, but individual spotters are encourage to report any flooding and gusty winds to the National Weather Service office in Miami, FL.
