Area Forecast Discussion National Weather Service Miami FL 301 PM EST Thu Dec 5 2019

Discussion.

Short Term (Tonight through Friday Night): the only noteworthy feature this afternoon are veils of cirrus racing across the South Florida skies as the area remains under the influence of high pressure centered over the SE CONUS. Temperatures tonight will be a few degrees warmer, with upper 40s to low 50s across most of the region. The only exception being the east coast metro areas, which will be near 60.

Through the day tomorrow, the surface high will continue to slide eastward into the western Atlantic, veering winds further out of the east to southeast. The return of an easterly component to the flow will moderate the airmass and induce a gradual warming trend across the region. Afternoon temperatures are forecast to climb into the upper 70s across most of the area and low 80s over the southwestern portions.

.Long Term (Saturday-Thursday): Saturday, the dominant high pressure across the SE states will continue to migrate further east and into the West Atlantic. This will bring east to south east winds, which will be veering ahead of an approaching front. The parent low will be migrating across the southern states during the weekend, with the latest global models depicting the best dynamical support remaining to the north of SoFlo. Therefore, only a very modest increase in moisture and a few showers are expected for the Saturday through Monday timeframe.

With the described synoptic scenario in place, temperatures should continue to climb back to near normals with morning lows in the upper 50s to mid 60s by Sunday. Afternoon highs will likely hit the upper 70s to lower 80s.

For next week, model solutions show an amplifying mid-upper level trough across the eastern seaboard, which will once again veer flow to the south and southwest ahead of an associated frontal boundary moving thru the SE US and the peninsula. This will bring increased moisture advection from the south and increasing chances of showers from Tuesday and into the middle of the week. There are still some inter and intra-model differences regarding timing and overall intensity of this potential FROPA, so will refrain from departing from the consensus attm.

Marine. Generally dry conditions should continue into next week as high pressure remains across the region. Winds will begin to veer from northerly to easterly as high pressure slowly slides eastward tomorrow into the weekend. Seas will be generally 3 feet or less across local South Florida waters. The minor northerly swell over the Atlantic nearshore waters will gradually diminish through the day tomorrow.

Aviation. High pressure will keep dry, VFR conditions through the TAF period. Northerly flow may briefly swing out of the NNE this afternoon. Winds then become light and variable overnight with an increase out of the E to SE around 8 knots tomorrow.

Fire Weather. Conditions will improve tomorrow as easterly winds return, allowing minimum RH values to moderate back above 40.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
