432 PM EDT Thu Apr 9 2020

Small craft should continue to exercise caution across the Atlantic waters of South Florida throughout the next couple days due to breezy conditions. A weak cold front is expected to push into the Atlantic waters Friday into Friday night, with some thunderstorms possible Friday afternoon. Winds and seas will begin to increase early next week behind the cold front, potentially leading to advisory criteria.

Gulf Stream Hazards: Southerly winds around 15 to 20 knots.
The approximate location of the west wall of the Gulf Stream as of Apr 09, 2020 at 1200 UTC...
- 7 nautical miles southeast of Fowey Rocks.

.Short Term
After some morning stratus and a few foggy patches, this afternoon turned into a pleasant one. The only complaint filed is that the temperatures are a bit warm. As of writing this discussion, temperatures were already in the lower 90s for FXE, OPF, MIA, TMB, and HST. APF is the cool spot with onshore flow helping mitigate some of the heat along the Gulf.

As cold front currently along the I20 corridor will continue to slide southward with time through the short term. This will provide a focus for showers and possible a T'storm or two, especially along the I95 corridor and closer to the Lake region. Looking at a few soundings, there looks to be at the very least modest instability. Although winds will be unidirectional through the column...one entity of interest on the forecast soundings would be an inverted V indicating a signal for stronger downburst winds if, indeed, convection does develop. This of course would be the primary concern at this juncture. That said, models are indicating a decaying Quantitative Precipitation Forecast signal with time. The better potential again would be around the Lake generally between 18z and 00z Saturday.

As the front moves through and rain should come to an end from northwest to southeast. Northerly winds will begin to increase with a subtle cool/dry airmass beginning to settle into the region by the end of the period.

.Long Term... On Saturday, temperatures will drop a bit on the east coast as they will rise into the lower 80s, however, they will still remain on the warm side across the interior and west coast as they climb to near 90 in the afternoon. A slight chance of showers cannot be ruled out especially in the afternoon as there will be enough low level moisture remaining in place. As for Sunday and Monday, the latest computer model guidance shows a rapidly deepening area of low pressure moving through the Ohio Valley and into the Great Lakes region. The cold front associated with this system pushes southward into the Northern and Central Florida area by Monday afternoon. Across South Florida, a ridge of high pressure will move into the open Atlantic waters during this time frame. This will allow for the wind flow to shift from a southeasterly direction on Sunday to a more south to southwesterly direction out ahead of the approaching cold front on Monday. A slight chance of showers cannot be ruled out on Sunday, however, many areas will remain dry during this time frame. With the flow turning more south southwesterly, temperatures will warm up quite a bit early next week as they will range from the upper 80s across the immediate east coast to the mid 90s across interior sections.

By the middle of the week, the ridge of high pressure in the Atlantic to our south will start to flatten out, which will allow for the cold front to continue its southward push into South Florida during this time frame. The latest computer model guidance is still trending slower, however, it looks like the front will be close enough to start increasing the chances of showers and thunderstorms by the middle of the week and into the end of the week as well. This will continue to be monitored as the rest of this week progresses. High temperatures during this time frame will still continue to be above average, with the possibility of some slight cooling towards the end of next week depending on the position of the cold front and the associated cloud cover with the possibility of some showers and thunderstorms.

Marine
Winds out ahead of the approaching front will increase across the Atlantic waters tonight. SCEC headlines are up for those zones. Winds will likely subside during the day Friday as the front begins to push through then quickly increase behind the front later Friday night. At the moment, only expect SCEC conditions...which should continue off an on through Sunday. Speaking of Sunday, winds will quickly transition to a southeasterly direction and increase again. Hazardous marine conditions can be expected for the Atlantic waters and maybe even Gulf waters from Sunday morning through Monday afternoon.

.Aviation... VFR conditions expected through tonight before CIGs begin to drop around or just after sunrise as a front nears. VCs will cover any precipitation with the front. Winds will be tricky later on as the will begin to transition from southerly to westerly to eventually northwesterly.

.Beach Forecast... With the surface flow being more westerly, Atlantic rip current potential has decreased to low/moderate category. However, with the slight uptick in westerly winds, Collier Beaches may see a modest increase in potential, however, with the somewhat modest flow only expect low to moderate risk here as well.
