For southeast Florida weather, during the day, it was mostly sunny to partly sunny early. Around early afternoon, showers and thunderstorms were developing just inland from the coast mainly in Broward County. As the afternoon progressed, areal coverage and intensity increased.
The National Weather Service was quite busy during the afternoon as some of the activity became strong. Several Weather Statements were issued for gusty winds, excessive lighting, possible hail and for possible development of funnel clouds. Hail was reported in the Pembroke Pines area. Additionally, some of the storms were producing very heavy rainfall and Flood Advisory was issued for portions of Miami-Dade and Broward Counties.
As indicated in this morning’s update, with the upper Low over the area, temperatures aloft (500 mb) cooled to around -8° C which resulted in a more unstable atmosphere. Additionally, there was more moisture around both aloft and lower levels. And finally, the region was on the diffluent side of the Low. All of these ingredients made it prime for an active afternoon. Below is the animated water vapor imagery depicting the upper level Low.
High temperatures were mostly upper 80’s to low 90’s with a few areas reaching middle 90’s while few coastal areas were in the middle 80’s. Heat indices ranged from middle 90’s to near 100.
For tonight, it will be partly cloudy. There will isolated to widely scattered shower or thundershower. Lows will be in the middle to upper 70’s. Some well inland areas may drop to around 70 to low 70’s.
Winds will be south southeast at 5 – 15 mph. Seas will be 2 – 3 feet. Intracoastal waters and Biscayne Bay will have a light chop.
The upper level Low that has been around south Florida for the last several days’ looks like will finally get “out of our hair” as it moves west and weakens. This will allow for the low/middle level High in the Atlantic east/southeast of Florida to shift northward. This will deepen the east and mostly southeast wind flow over the next couple of days.
Sunday may still be a transitional day with a general southerly steering flow/possibly becoming more southeast late. This will favor most of the shower and thundershower activity over the interior and northern portions.
As the southeast and east wind flow deepens, it will favor afternoon and evening showers and thundershowers over the interior and western areas during the afternoon and evening hours. The eastern areas will be favored with night and morning showers and thundershowers. Without any features moving through the area, the interior and western areas will have the most coverage of the showers and thundershowers as daytime heating and sea breeze interaction will promote the most activity.
For Sunday, it will partly sunny to partly cloudy. There will be scattered showers and thundershowers. Highs will be in the middle 80’s to low 90’s. Some areas in the interior may reach middle 90’s. Lows Sunday night will be middle to upper 70’s.
Winds will be south southeast to southeast becoming southeast to east southeast Sunday night at 5 – 15 mph. Seas will be around 2 feet. Intracoastal waters and Biscayne Bay will have a light chop.
For Monday (Labor Day), it will be partly sunny to partly cloudy. There will be scattered showers and thundershowers. Highs will be in the upper 80’s to low 90’s. Some areas in the interior may reach middle 90’s. Lows Monday night will be in middle 70’s to near 80.
Winds will be south southeast to east southeast at 5 – 10 mph. Seas will be around 2 feet or less. Intracoastal waters and Biscayne Bay will have a light chop.
For Tuesday, it will be sunny to partly sunny. There will be widely scattered to scattered showers and thundershowers. Highs will be in the middle 80’s to low 90’s. Some areas in the interior may reach middle 90’s. Lows Tuesday night will be in the middle 70’s to low 80’s.
Winds will be southeast to east southeast at 5 – 10 mph. Seas will be less than 2 feet. Intracoastal waters and Biscayne Bay will have a light chop.
A tropical wave (currently located in the Atlantic approaching the Lesser Antilles) may approach the area toward the end of the week/weekend.
