Area Forecast Discussion National Weather Service Miami FL 639 AM EST Sun Feb 23 2020

Aviation. Prevailing VFR conditions expected across S Fl and all terminals throughout the period. Isolated SHRA along the Atlantic coast continues to diminish this morning. Handled this shower activity with VCSH for some east coast sites. Winds will veer from NE to E across S Fl throughout the period.

Prev Discussion. /issued 410 AM EST Sun Feb 23 2020/

Short Term (Sunday through Tuesday Morning) .

The main updates to the forecast package this morning are the extension of the Small Craft Advisory for the Atlantic waters of South Florida and the extension of a High Surf Advisory for coastal Palm Beach County.

Sunday .

Surface high pressure is currently situated over the Southeast CONUS, while South Florida remains on the southern periphery of the air mass. For this reason, the pressure gradient remains tight across South Florida, allowing for breezy northeasterly to easterly winds throughout the day today. In addition, the onshore wind component has allowed for the continuation of isolated rain showers across the Atlantic waters which are advecting across the east coast metros of South Florida this morning. This shower activity should slowly diminish throughout the morning today as slightly drier air advects into the region. Hazardous marine and beach conditions will continue throughout the remainder of the day today before improving on Monday (See Marine and Beach sections below). Minimum temperatures this morning will be in the 50s across the interior and Gulf Coast of South Florida, while the eastern areas will experience the low to mid 60s. Maximum temperatures this afternoon will be in the 70s across most of South Florida, while the Gulf Coast may reach 80.

Monday into Tuesday Morning .

Winds will begin to veer from an easterly direction to a southeasterly direction, allowing for low-level moisture advection across South Florida. Therefore, isolated rain showers will be possible along the eastern coast of South Florida on Monday before diminishing throughout the day. Minimum temperatures on Monday morning will be in the 50s across the interior and Gulf Coast of South Florida, while the eastern areas will experience the mid 60s. Maximum temperatures Monday afternoon will be in the upper 70s across most of South Florida, while the Gulf Coast may reach the lower 80s.

Winds will continue to veer to a southerly direction on Tuesday ahead of an approaching cold front.

Long Term (Tuesday through Saturday) .

A cold front pushes across North Florida and the eastern Gulf of Mexico on Tuesday as a surface low moves across the Ohio River valley into the Great Lakes region. Aloft, a mid-level trough will depart and leave the front lingering across some portions of northern and central Florida before the next mid-level impulse comes along. Ahead of the front, a persistent southerly flow will allow moisture to increase. Temperatures will also be able to rebound into the 80s during the day and remain in the mid 60s to mid 70s across South Florida on Tuesday night into Wednesday morning. Cannot rule out the potential of some pre-frontal fog on Wednesday morning.

Through the day on Wednesday, the mid-level low over the upper midwest will come into phase with the surface low over the Great Lakes which will allow the surface front draped along the eastern seaboard into Florida to resume its eastward and southward progress. This will lead to increasing shower and thunderstorm chances through the day on Wednesday. The front is forecast to pass through the area Wednesday night into Thursday morning. As drier, cooler air enters the region behind the front, temperatures will struggle to reach into the mid to upper 60s across much of the area. A later frontal passage could allow for some warmer temperatures than forecast on Thursday.

We enter a cooler period to end the week with surface high pressure settling in over much of the nation's middle. That will allow for a persistently northerly to northwesterly flow for several days which will bring drier, cooler continental air southward. The path over the peninsula of Florida will keep moderation from either the Gulf of Mexico or Atlantic Ocean to a minimum. Temperatures in the 40s and 50s overnights and 60s and 70s during the days, which are a bit cooler than seasonal norms for late February/early March, are forecast.

Marine .

Breezy northeasterly to easterly winds, large swell, and elevated seas of 6 to 11 feet across the Atlantic waters will continue throughout the day today bringing hazardous marine conditions. Therefore, a Small Craft Advisory remains in effect for the Atlantic waters of South Florida through this afternoon, while the Small Craft Advisory will continue through tomorrow morning for the Palm Beach County waters as waves in the Gulf stream will take additional time to subside. Winds and seas should begin to subside throughout the day today as the high pressure weakens and moves farther out over the Atlantic waters.

Beach Forecast .

Breezy onshore flow and large northeasterly swell will continue today, allowing for the continuation of hazardous beach conditions for the Atlantic coastline of South Florida. A High Surf Advisory is in effect for coastal Palm Beach County through this evening, while a High Risk of Rip Currents remains in effect for all Atlantic beaches of South Florida through this evening. Rip currents may remain elevated along the Atlantic beaches of South Florida throughout the next couple of days.
