AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 401 Pm Edt Sun Apr 18 2021
Synopsis.. The good boating conditions continue tonight despite a weak northeasterly swell still lingering over the atlantic waters off palm beach county. Periods of cautionary conditions are possible across portions of the atlantic waters during the first half of the week, as a cold front across central portions of the state will lead to increasing rain and Thunderstorm chances. The strongest activity may produce brief heavy rainfall, which may lead to reduced visibilities. Additionally, frequent cloud-to-water lightning, gusty winds, and localized higher seas may also be possible.
Gulf stream hazards..Increasing chances of showers and Thunderstorms with gusty winds and locally higher seas will be possible through mid-week. The approximate location of the west wall of the gulf stream as of apr 17, 2021 at 1200 utc... 6 nautical miles east northeast of fowey rocks. 8 nautical miles east northeast of port everglades. 4 nautical miles southeast of lake worth. 8 nautical miles southeast of jupiter inlet.

. A Few Strong Storms Possible North of I75 Early Week .
SHORT TERM (Tonight through Tuesday).
A pattern shift is on the way with the relatively drier and warm conditions giving way to a wetter start to the work week as a cold front currently over north central Florida begins to push southward over the peninsula of Florida. Other surface boundaries are also in the picture with an earlier boundary entering the region from the south that could allow some convection to develop over some portions of southern Florida this afternoon. Another potential source for convection today is a pinned Atlantic sea breeze that could allow for some activity over portions of Palm Beach and Broward Counties later this afternoon into the evening. As the sun sets, convection will diminish over land and eyes will turn to the north and west as the approaching pre-frontal convection may enter the region tonight into Monday.
With the approaching front, increasing moisture and an approaching low level jet will provide some support for shallow shower activity while a few co-incident passing mid-level shortwave troughs could provide the localized support for flare ups of thunderstorms as they pass around peak diurnal heating time on late Monday morning into the afternoon. Some slightly cooler air aloft with these troughs will combine with the heating of the surface to provide for more unstable lapse rates which should be able to defeat whatever is left of the inversion by midday allowing for convective coverage and intensity to increase.
Strong to severe thunderstorms cannot be ruled out, particularly from Alligator Alley northward which is closer to the approaching boundary, the edge of the low level jet, and appears to be the forecast target of the mid-level shortwave trough's vort max. Frequent lightning and heavy rain are concerns with any thunderstorm that develops, but damaging winds, hail, and excessive rainfall are certainly concerns with strong to severe thunderstorms that could develop with the aid of the support aloft. Accordingly, there could be some lulls in convection at times which could allow for reduced cloud cover which could provide for additional heating and instability for future rounds of storms. Repeated rounds of heavy rainfall over sensitive areas, such as poorly draining urbanized areas, could lead to some ponding of water as well.
Highs on Monday and Tuesday should be a few degrees cooler than they have been this weekend around 90 degrees except mid to upper 80s over the western areas. However, with the higher humidity over South Florida early this week, the heat indices will be in the mid 90s to near 100 over most areas, except for the west coast metro areas where they will be lower to mid 90s.
LONG TERM (Tuesday night through Sunday).
The cold front will continue slowly move southward by midweek. At the start of the long term, PWATs across the Lake Okeechobee region will be near if not exceeding record levels. Although the PWATs are more than juicy, absorption should be quite significant given climo and antecedent conditions. Still, can't rule out some urbanized hydro issues. Globals are in fairly good agreement with the front moving through afternoon or evening on Thursday. Prior to this time, will keep POPs for convection relatively high because of the continuation of deep layer moisture and subtle H5 impulses. That said, timing of the front my be still questionable depending on convection and cold pools/outflow that can give the front a forward boost allowing for a quicker passage, but these mesoscale concerns will be addressed as time progresses.
Behind the front a zonal/progressive flow develops over the region going into this weekend. Very weak QPF signals still reside in the globals, so it may not be completely dry, but any shower activity would be the exception rather than the rule as the column dries rather significantly. The old front will eventually lift back northward later this weekend as a storm system sets up across the Mississippi River Valley. Spatial and temporal uncertainty becomes evident within the forecast guidance as the ECM is a bit more progressive. Regardless, low-end POPs next weekend will be needed for the surface feature and perhaps some subtle mid-level impulse(s) at that time.
Temperatures will be held down early with increased cloudiness and precip. However, a warming trend is expected, especially toward the end of the period as the front lifts northward and heights gradually increase over the Caribbean and Gulf of Mexico.
AVIATION(18Z TAFS).
Generally southwesterly to westerly flow through the period though a weak Atlantic sea breeze could turn the east coast terminals more southerly at times this afternoon. Sea breeze could provide a focus for some convection before the front moves closer tonight bringing increasing shower and storm activity to close out the forecast period.
MARINE.
A cold front approaching the area will bring increasing chances of showers and thunderstorms back into the forecast for much of the week. Periodic cautionary conditions are possible in the Atlantic waters at times through at least mid-week.
Beach Forecast. An elevated rip current risk may linger across portions of the Atlantic beaches, particularly the Palm Beaches, this afternoon due to small E/NE swell. The rip current risk should begin to diminish early in the week as the swell dissipates.
