Area Forecast Discussion National Weather Service Miami FL 218 AM EDT Mon Sep 27 2021

SHORT TERM (Now through Tuesday).

The long anticipated pattern change has finally arrived across south Florida. Drier air within northwesterly upper level flow will limit diurnally driven convection this afternoon across our land based zones. Conditions outdoors today should also be a bit more tolerable with dewpoints dropping into the middle and upper 60s across the interior where some of the driest air aloft will mix toward the surface. That said, it's been a long wet season so this will be moderated just a bit due to evapotranspiration, but still being outside will have a "different" feel than the last few weeks (months?). Otherwise, boundary layer maintenance (low level moisture advection) right along the Atlantic Coast with a light to moderate onshore flow will keep these areas from really enjoying the first taste of "dry" season in terms of lower humidity values.

That said, some nocturnal showers will be possible during the overnight hours, especially where the better boundary layer moisture resides closer to the Gulf Stream. Can't rule out a rumble of thunder or two, but with the very dry column, vertical extent will be limited, so thunder is certainly the exception rather than the rule.

Going into Tuesday, not much change is expected with the dry spell continuing for much of the region. With perhaps a few showers developing over the waters, adjacent coastline does get a low POP mentioned, but most locations west of Krome AVE/HWY 27 will more than likely be dry. Temperatures will still be very warm, but similar to Monday, mixing across the interior will hold heat index values down to more tolerable levels.

LONG TERM.

Tuesday Night through Thursday

A dry airmass will continue to impact the region in the wake of a southward moving (modified) cold front. Expansive surface ridging originating from the coastal Carolinas will allow for mean steering flow to be directed out of the northeast, allowing cooler and drier air to advect towards the region. Several prognostic solutions suggest precipitable water values of less than 1.0 in, which would be near the all time minimum per sounding climatology. Therefore PoPs do not exceed 30 through this period for most of South Florida, with the exception being the southern-most extent of the region. Additionally, a lack of instability from decreased SFC-850 hPa dewpoints will significantly hinder thunderstorm chances.

Friday through Monday

An amplified, positivity tilted short-wave trough is forecast to emanate from long-wave troughing over the Atlantic Ocean and dig southward. An attendant surface front appears to materialize in association with this feature, and may clear the region, resulting in similarly dry conditions. It does appear that a gradual moistening occurs, albeit conditions still remain much drier than typical for this time of year. Persistent northeasterly flow should favor coastal convergence along the Atlantic coastline, where the greatest shower and isolated thunderstorm chances will be present through this period. Any convection that does develop will be generally benign, with locally gusty winds being the main hazard for any affected locations.

Temperatures through this period will about a degree or two below seasonable norms, as maximum temperatures in the upper 80s can be expected across the region. The passage of a modified cold/front will allow for a reduction in dewpoints and hence apparent temperatures compared to traditional values for this time of year.

AVIATION(06Z TAFS).

VFR conditions should prevail through the forecast cycle. Easterly or northeasterly winds are expected and may become moderate during the daylight hours today. Otherwise, any convection should remain offshore away from the terminals today.

MARINE.

Light to moderate easterly will continue through much of the workweek. Isolated showers and perhaps a thunderstorm or two will be possible, especially during the overnight hours along the Gulf Stream.

BEACHES.

A moderate risk of rip currents exists along the Atlantic beaches today as moderate onshore flow continues.
