Area Discussion for - Miami-South Florida, FL
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 232025 afdmfl area forecast discussion national weather service miami fl 425 pm edt Sat mar 23 2019 Discussion Tonight and Sunday... the mid-level ridge axis currently located from the western great lakes into the eastern gulf of mexico will shift towards the western atlantic in response to a shortwave trough advancing from the central great plains into the mid mississippi valley. This will cause the surface ridge now located over the ohio valley to shift into the western atlantic in response. With south florida along the southwestern periphery of the surface ridge, easterly winds will increase on Sunday with an uptick in cloud cover arriving from the east as well. Low-level moisture will increase slightly, but any meaningful shower chances should hold off until Sunday night at the earliest. Some moderation in temperatures will occur given the easterly flow, with overnight lows ranging from the lower to mid 50s for areas west of lake okeechobee, mid to upper 50s for the remainder of the interior and gulf coast, and lower to mid 60s for the east coast metro areas. A good warm-up is then expected on Sunday, with highs mostly in the upper 70s to lower 80s, with a few mid 80s possible over inland collier and mainland monroe counties. Sunday night through Tuesday... aforementioned shortwave trough will gradually lose amplitude while progressing form the ohio tennessee valleys into the south atlantic states. A weak surface front attendant to the upper system will gradually push into our area on Tuesday, likely turning the winds north to northwest for a time late in the period. Regardless of any wind shift, no meaningful cold advection will occur with moderating temperatures continuing. Highs should mostly be in the 80s, with upper 50s and 60s for lows. The easterly flow on Sunday night will bring the first push of better low-level moisture allowing for shower chances initially for the atlantic and east coast, then spreading inland to the interior by Monday afternoon. Shower chances should decrease, or perhaps be confined to areas near over the atlantic waters by Tuesday afternoon and evening. Wednesday through Saturday... shortwave energy will allow the upper trough to deepen across florida and the western atlantic, while a secondary cold front passes through our area early in the period. A robust pressure gradient will develop as surface and mid-level ridging build in behind the front, resulting in gusty winds (especially over the |
atlantic and outer gulf waters) from Wednesday into at least Thursday night. Temperatures will be a bit cooler on Wednesday with some cloud cover and a few atlantic east coast focused showers possible. Some warming is then expected heading into the weekend. Marine Easterly surges of wind through the weekend may produce cautionary conditions over the waters with brief bouts of advisory conditions possible in the gulfstream. The next period of hazardous conditions will arrive on Wednesday into Friday behind a front. Expect gusty winds and building seas during this time. Atlantic seas of 9 to 12 feet are possible. Aviation Vfr conditions to prevail, although with winds becoming stronger out of the east on Sunday, expect sct bkn layer between 3,000-4,000 ft at east coast sites beginning by 12z-14z Sunday. In the meantime, only few sct clouds all sites. Sea breezes through 00z near 10 knots, then wind staying E 7-10 knots east coast overnight, and E increasing to 15 knots with some gusts near 20 knots by 14z Sunday including gulf coast kapf. Beach forecast An elevated risk of rip currents will likely persist through a good portion of the week. Increasing winds behind frontal passage will allow seas to build which could lead to not only a high risk of rip currents mid to late week but also the potential for beach erosion and some coastal impacts. It is still early in the forecast period but those with interests tied to coastal flooding should monitor the forecast evolution through the weekend and early next week in case the threat to the coast materializes and a high surf advisory or coastal flood statement become necessary for the atlantic.
