Area Forecast Discussion . UPDATED National Weather Service Miami FL 831 AM EST Tue Jan 19 2021

UPDATE. High pressure will remain in place over South Florida today keeping the weather. The winds will also be northeast at 5 to 10 knots.

PREV DISCUSSION. (Issued 700 AM EST Tue Jan 19 2021)

AVIATION(12Z TAFS) . The winds will remain from the northeast today at 10 knots or less at all of the TAF sites. The weather and ceiling will also remain in VFR conditions at all TAF sites.

PREV DISCUSSION . (Issued 234 AM EST Tue Jan 19 2021)

DISCUSSION .

SHORT TERM (Today through Wednesday): Weak high pressure encompassing the FL peninsula and rising heights aloft will help keep dry and pleasant weather in place the next several days. The placement of South Florida within the southeastern periphery of the surface high will maintain gentle NE to E flow, which should gradually moderate temperatures back to near seasonable and slightly above.

Daytime highs will be in the lower to mid 70s across South Florida with overnight lows dipping into the upper 40s to lower 50s across the interior/Lake region and upper 50s near 60 over the eastern coastal and metro areas.

LONG TERM . (Wednesday Night through Monday): broad high pressure should remain in control of the are weather through the rest of the work week, and keeping generally benign/dry conditons in place. A prevailing light northeasterly flow should also continue until around the middle of the week, with temperatures near normals each day. For most of Soflo expect afternoon highs in the mid 70s, along with morning lows in the upper 40s-mid 50s inland and upper 50s to low 60s elsewhere.

Models remain fairly consistent in showing a potential backdoor cold front approaching the area during the weekend. Some low level moisture is finally able to filter into the dominant drier air mass as winds veer to a more southerly flow ahead of the front, but not enough to cause significant rainfall. Best chances of a few showers developing will be Sunday afternoon with daytime heating, favoring the Atlantic coast. On the other hand, the southerly winds will bring warmer temps across Soflo with some spots possibly hitting the lower 80s, especially inland.

AVIATION(06Z TAFS) . Dry, VFR conditions prevail through taf cycle. Light and variable winds pick up out of the east tomorrow afternoon and diminish again for the overnight hours.

MARINE . High pressure across the local waters will maintain benign marine conditions for the next several days with no meaningful weather impacts anticipated.

BEACHES . With the return of onshore flow across the Atlantic beaches, a elevated risk of rip currents may be possible the remainder of the week.

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.
