Area Forecast Discussion National Weather Service Jacksonville FL 147 PM EDT Sun Apr 18 2021
AVIATION. [Through 18Z Monday]
Bouts of scattered showers will move through the region until later this afternoon and evening, where another bout of thunderstorms and heavier rains is expected to move through across NE Florida, south of the frontal boundary. Ceilings can be expected to drop to IFR levels during this period with cloud heights remaining low for Florida sites into Monday morning.
PREV DISCUSSION [902 AM EDT].
NEAR TERM [Through Tonight].
Surface frontal boundary has slipped back southward into North Central Florida and expect next wave of showers and embedded storms to mainly impact Northeast Florida through Tonight with lesser rainfall expected across Southeast Georgia. Locally heavy rainfall will continue at times along with a few strong to isolated severe storms with the main threat as hail in elevated cores to the north of the surface boundary, but even some gusty winds will still be able to mix down at times. Severe storm threat mainly expected today and tonight along and south of a line from Gainesville to St Augustine. Abundant cloud cover and rainfall will hold Max Temps in the lower to middle 70s and Min Temps only falling into the upper 50s and lower 60s.
SHORT TERM [Monday Through Tuesday Night].
Monday and Monday Night . Trailing shortwave/impulse pushes frontal boundary all the way southward into Central Florida and this will end rainfall chances across SE GA and limit showers and storms across NE FL and push them mainly south of a line from Gainesville to St Augustine through Monday Night and better chances of partial sunshine should push Max Temps back into the mid to upper 70s for most locations with Min Temps mostly in the 50s Monday Night.
Tuesday and Tuesday Night . Models still in decent agreement that next shortwave impulse aloft will trigger low pressure development along the frontal boundary across the Eastern Gulf of Mexico which will track across North Central Florida with a final round of heavy rainfall which could be the most widespread and intense of the multi-day event and an additional 2-4 inch rainfall totals across NE FL could warrant the need for a Flood Watch depending on rainfall totals Today and Monday. This rainfall event will hold temps at below normal levels with highs only in the lower/middle 70s once again. Rainfall will begin to taper off Tuesday Night as low pressure exits off the Atlc coast after midnight with lows in the upper 50s/near 60 degrees.
LONG TERM [Wednesday Through Saturday].
Wednesday . Low pressure departs into the Atlantic and expect clearing skies with warm temps into the lower 80s for most locations ahead of secondary cold frontal passage that takes place late in the day and ushers in much cooler airmass with lows falling into the 40s inland and lower 50s along the Atlc coast Wednesday Night.
Thursday . Cool northerly flow will lead to below normal temps under Sunny skies with high only around 70 degrees in most locations and another night with lows in the 40s over inland areas for Thursday Night.
Friday . Increasing clouds ahead of next weather system with a return to climo temps with highs in the mid/upper 70s, then enough moisture returns with a few showers possible by late Friday Night.
Saturday . Long range models suggesting a shortwave in the zonal flow aloft will push across the region with numerous to widespread showers and embedded storms with locally heavy rainfall possible once again with temps continuing at near normal levels.
MARINE.
Light offshore flow with no headlines are expected through Monday becoming onshore on Tuesday as low pressure tracks along frontal boundary south of the waters with main impacts still the showers and embedded storms with heavy rainfall at times. A secondary frontal passage on Wednesday will bring a surge of northerly winds around 20 knots Wednesday Night and early Thursday that may lead to Small Craft Advisory conditions.
Rip Currents: Low end Moderate risk of rip currents will continue this weekend with surf/breakers around 2 feet.
FIRE WEATHER.
Low daytime dispersion values will continue due to light surface and transport winds through Tuesday.
HYDROLOGY.
So far the greatest impact of rainfall the past 24 hours has been the 3-6 inch rainfall totals across Marion/Putnam/Flagler counties with only minimal impacts due to antecedent drier conditions and with rainfall to remain locally heavy today and tonight across NE FL will hold off on Flood Watch issuance at this time. The best chances of more significant widespread heavy rainfall will be on Tuesday as low moves along frontal boundary and this may be when a Flood Watch needs to be post for some locations of NE FL south of the I-10 corridor due to the 3-6 inch storm total rainfall amounts expected by Wednesday Morning. Minor River flooding may still be possible along the upper Santa Fe Basin, but greatest flooding impacts will continue to be the metro areas of NE FL including Ocala, Gainesville, Jacksonville and St Augustine thru Tuesday.
