1047 am edt Sun may 26 2019

Discussion
Deep layer ridging rooted in central america reaches northeast
into the southeastern united states. Remarkably high mid-level
heights persist over northern fl and southern ga al ms. In fact,
record 500mb heights continue at jax, tae, and lix (see 12z
raobs). The surface anticyclone is beneath the mid-level ridging
and supports fresh easterly breezes across the florida keys. The
12z kkey RAOB sampled just over an inch of pw, which is beneath
the 10th percentile for the date. Significant inhibition near
850mb gives way to weak instability aloft.

The kbyx radar is echo free and skies are mostly sunny. Highs
should reach the upper 80s this afternoon with no rain chances.

Easterly breezes will be windy at times. The forecast is on track
and needs no adjustments.

Marine
High pressure centered just to the west of bermuda supports fresh
easterly breezes across the coastal waters of the florida keys.

Although this system will settle southward over the next few days,
periods of moderate to fresh, east to southeasterly breezes will
be maintained through the forecast period.

Aviation
Vfr and gusty easterly breezes will prevail at the eyw and mth
terminals through the afternoon.

Key watches warnings advisories

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
