Area Forecast Discussion National Weather Service Melbourne FL 309 PM EDT Mon Sep 12 2022 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Rest of Today-Tonight...A bit of a slower start compared to this time yesterday, especially along the east coast sea breeze. Nonetheless, showers and storms along and ahead of the west coast sea breeze are now making their way into portions of the interior as of around 3pm. Over the next several hours, expect coverage of showers and storms to become scattered to numerous across the area, especially along the anticipated sea breeze collision later this afternoon. Persistent slower storm motions (around 10mph or less) and high PWATs (2-2.3") will continue to generate a localized heavy rainfall threat, with accumulations up to 3" in a short period (60-90 mins) possibly leading to minor flooding, especially in areas that have received heavy rainfall over the last several days. In addition, forecast 500mb temps of -6.5 to -7.5C will support a few strong storms, which will be capable of wind gusts to around 50mph and frequent lightning strikes. An isolated severe storm cannot be ruled out. Outflow boundaries are expected to continue to generate showers and storms through the evening hours, with light SW steering flow causing cells to drift back towards the coast during this time. This activity should push offshore by around 10-11pm, with drier conditions prevailing for the remainder of the overnight hours. Morning lows in the low to mid-70s expected. Tuesday-Thursday (modified previous)...Mid/upper level cutoff low across the Great Lakes region ejects northeast, with a trough extending down the eastern U.S. coast through mid-week. At the surface, this shifts a weak frontal boundary southward into north FL on Tuesday, which eventually stalls across central FL toward Wed-Thu. This will keep a moist airmass in place and continue a wetter than normal pattern across the region through the work week. Rain chances remain elevated up to 70-80 percent each day, with scattered to numerous showers and storms developing each afternoon along the sea breezes and any boundary collisions across the interior through early evening. Steering winds will generally remain out of the S/SW, which will allow some storms to shift back toward the coast and offshore each day. Some stronger storms will continue to be possible, producing frequent lightning strikes and gusty winds to 40-50 mph. Locally heavy rainfall of 2-3 inches will be possible each day with slower moving storms or repeated rounds of rainfall. This will continue a minor flood threat, especially over areas where the ground is already saturated from heavier rainfall over the past few days. Highs will reach the upper 80s to low 90s each day ahead increasing shower/storm coverage and increased cloudiness through the afternoon. Overnight lows will continue to range from the low to mid 70s. Friday-Monday (previous)...00Z GFS and ECMWF models diverge into late week and into the weekend. The GFS has a mid-level S/W lift NE across the SE states, which develops low pressure along the stalled boundary off the GA/SC coast and lifts NE. However, the ECMWF does not show this feature and instead has strong area of high pressure pushing SE and offshore the eastern U.S. coast with ridge axis remaining well north of the area. Either way rain chances look to remain near to above normal through the period, continuing a wetter pattern, as frontal boundary either lingers or gradually fades across the area through the weekend. PoPs range from 60-70 percent Fri-Sat, and then fall slightly to 50- 60 percent into Sunday-Monday. Low level onshore flow will initially focus greatest coverage of showers and storms over the interior with the inland moving east coast sea breeze each afternoon. However, steering flow generally stays out of the SW, which should still push some convection back toward the coast and offshore. A few stronger storms will continue to be possible each day, as will the potential for minor flooding from slow moving or persistent storms. Highs will continue in the upper 80s to low 90s and overnight lows in the low to mid 70s. && .MARINE... Issued at 225 PM EDT Mon Sep 12 2022 Rest of Today-Tonight...Scattered to numerous showers and storms over the interior this afternoon are expected to drift towards the east coast and into the nearshore waters late this afternoon into this evening. A few will be capable of gusty winds, frequent lightning strikes, and heavy rainfall. This activity will diminish by around midnight. However, isolated showers and storms will remain possible across the offshore and Gulf Stream waters overnight. S/SE flow this afternoon becoming SW/W again after sunset, remaining around 10kts or less. Seas 3-5ft, with increasing period. Tuesday-Friday (previous)...Weak westerly flow around 5-10 knots Tuesday morning becomes onshore by the afternoon as the east coast sea breeze develops. Winds then become more onshore into the rest of the week as a weak frontal boundary moves southward into central FL and stalls across the area. This boundary combined with deeper moisture will lead to higher coverage of showers and storms across the waters, with some stronger storms potentially pushing offshore along the coast each afternoon and evening. Outside of storms, wind speeds remain less than 15 knots. A long period (14-15 sec) swell up to 4-5 feet will exist across the waters Tuesday, which may cause hazardous boating conditions near inlets during the outgoing tide. Wave heights and periods then gradually decrease through the remainder of the week, falling to 2-3 feet with periods around 10 sec by late week. && .AVIATION... (18Z TAFS) Issued at 225 PM EDT Mon Sep 12 2022 An active convective pattern across the area expected this afternoon, with VCTS at all sites as showers and storms move into the area from the west and collide with the east coast sea breeze. TEMPOs in place over the interior 19-22Z and along the coast 20-23Z for TSRA and reduced CIGs/VIS. Gusty conditions possible as boundary collisions occur over TAF sites, with winds outside of convection primarily out of the SW at 7-12 kt. Conditions improving around 00Z over the interior and 03Z along the coast as storms move offshore, with winds becoming light and variable to calm at all sites overnight. Tuesday morning, winds pick back up at 7-10 kt. && .HYDROLOGY... Issued at 225 PM EDT Mon Sep 12 2022 Recent heavy rainfall and backing up of the Saint Johns River at Astor has led to rising river levels to action stage at this location. River levels are forecast to remain steady around Action Stage of 2.0 feet through this week. && .PRELIMINARY POINT TEMPS/POPS...

Scattered to numerous lightning storms will develop along collisions between the inland moving east coast sea breeze this afternoon and outflow from storms that develop over the eastern Gulf of Mexico and push in from the west-southwest. Boundary collisions will produce a few strong storms containing wind gusts up to 50 mph and frequent lightning strikes. An isolated storm with the potential to produce damaging winds near 60 mph cannot be ruled out. If threatening weather approaches or thunder is heard, seek shelter in a sturdy building. .FLOOD IMPACT... Slow storm motion and locally heavy rainfall up to 3 inches will produce conditions favorable for temporary flooding of urban areas, low lying areas, and those with poor drainage, especially in areas that receive repeated rounds of heavy rains. .EXCESSIVE HEAT IMPACT... Peak heat indices of 102 to 107 will occur this afternoon prior to the onset of clouds and storms. If engaged in outdoor activities, take frequent water breaks in the shade or in air conditioned buildings. .RIP CURRENT IMPACT... Incoming northeast swell will produce a HIGH risk of life threatening rip currents at the central Florida Atlantic beaches. Entering the water is not recommended. .MARINE THUNDERSTORM GUST IMPACT... Lightning storms will affect the inland lakes, intracoastal and nearshore Atlantic waters during the afternoon and evening. Gusty winds of 35 knots or greater will accompany the stronger storms along with frequent lightning strikes and torrential downpours. .RIVER FLOOD IMPACT... The Saint Johns River at Astor is forecast to remain near Action Stage this next week. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. Scattered to numerous afternoon lightning storms will continue each day, with the stronger storms producing gusty winds, frequent lightning strikes, and heavy rainfall. Where soils are saturated from previous or repeated heavy rains, any additional rainfall will quickly produce ponding of water, especially in low lying areas. A high risk of rip currents looks to continue through mid week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight. Leahy
