Area Forecast Discussion National Weather Service Miami FL 1249 PM EST Sun Dec 15 2019

Aviation. Generally VFR through the period with easterly flow becoming gusty on Monday. Cloud cover from the Atlantic is possible near the end of the forecast period.

Prev Discussion. /issued 1130 AM EST Sun Dec 15 2019/

Update . No major updates this morning with sunny skies and cooler, drier air behind the front that passed through the area yesterday. Zonal flow returns aloft while high pressure builds in. Temperatures should reach into the upper 70s to lower 80s across much of the area with most places already in the mid to upper 70s. Have a wonderful Sunday!

Prev Discussion . /issued 343 AM EST Sun Dec 15 2019/

Short Term (Today through Monday Night) . A frontal boundary crossed SoFlo yesterday, with a drier and cooler air mass filtering into the area in its wake. Meanwhile, a deep high pressure ridge is expanding across the SE states, with its southern periphery bringing veering winds to the NE and E through the short term.

A short-lived cold air advection event will usher cooler low temps this morning with lower 50s over northern interior areas to lower 60s along the coast. But by this afternoon, the air mass will begin modifying rather quickly, with highs in the upper 70s to low 80s.

Weather conditions should be great for today and tomorrow, with a relatively stable air mass establishing across SoFlo and zonal flow establishing aloft as the aforementioned high pressure expands over the region in the wake of the FROPA. Temperatures bounce back on Monday with afternoon highs climbing into the low to mid 80s.

Long Term (Tuesday through Saturday Night) . Southeasterly to southerly winds and increasing rain chances are expected on Tuesday as a cold front pushes southeastward into the state. Scattered showers and thunderstorms are expected on Tuesday afternoon, with deeper moisture returning to the area. Additional showers will be possible along the actual cold front when it finally pushes through the area late Tuesday night through Wednesday morning, with breezy north to northeasterly flow expected in the wake of the front Wednesday and Wednesday night. Cooler and drier conditions are expected in the wake of the front, with high temperatures on Wednesday forecast in the upper 60s west of the Lake to the upper 70s across far South Florida. Since this depends on the front clearing the area Wednesday morning, any slowing of the front could have significant impacts to the high temperature forecast on Wednesday. Low temperatures Wednesday night are forecast to be the coldest of the period and range from the mid/upper 40s west of the Lake to near 60 right along the East Coast.

Northeasterly to easterly flow returns on Thursday into Thursday night as surface high pressure over the southeastern CONUS pushes eastward, kicking off another gradual moisture return over the area. Forecast gets quite interesting towards the end of the period as another cold front is expected to push across the area. GFS solution now has a less amplified trough pushing southeastward with the surface low developing off the Georgia coast and dragging a cold front across the area Friday night into Saturday. At the same time, it shows another low developing near Cuba and pushing quickly northeastward across the Keys and over the Bahamas before having the two lows do some sort of Fujiwara dance as they push northeastward over the Atlantic. The ECMWF is somewhat similar in that it shows a less amplified trough with the main surface low developing and deepening off the Georgia coast and dragging a cold front across the area on Saturday. It also has another surface low developing over the Bahamas and pushing northeastward with the other, stronger low. Right now it's far too soon to tell what kind of impacts, if any, South Florida would see from this system next weekend Plus, given the . odd solutions in these latest runs I would expect things to change at least a decent bit as we get closer.

Marine . Conditions in the Atlantic waters are subsiding as high pressure builds closer to the area. Persistent moderate easterly flow will return later today, keeping seas under highlight criteria. A mid- week cold front could bring periods of hazardous conditions over the area waters through the end of the work week.

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.
