Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Dry weather is expected through mid-week under high pressure. Rain
chances return Wednesday evening.
Near term until 6 pm this evening
A cold front will advance sewd across the region late this
afternoon. Daytime mixing and a tight pressure gradient ahead of the
frontal boundary will support gusty swly wind prior to frontal
Drier and cooler air will arrive post-front as sfc high pressure
builds, but ample afternoon Sun will lead to maxima near or just-
above average today. No precipitation is anticipated as the swly wind
ahead of the frontal boundary will eliminate moisture in the column,
and the building high pressure post-front will limit instability.
Short term 6 pm this evening through Wednesday night
Dry, cool air is expected Tue as high pressure continues to build
upstream from a broad nern-conus trough. Upper ridging and attendant
sfc high pressure will maintain dry conditions for much of wed, with
temperature returning to above-average levels.
A shortwave ridge is progged to traverse the upper-level high
wed night as a sfc warm front approaches from the southwest,
returning shower and thunderstorm chances to the forecast.
Long term Thursday through Sunday
The upper high is progged to persist over the sern CONUS through the
weekend. Waves traversing the NRN periphery of the high should result
in periodic shower and thunderstorm chances through the period.|
Above-average temperature is expected as heights increase markedly
amid the sern-conus ridge.
Aviation 17z Monday through Friday
Medium confidence that a period of MVFR CIGS will develop late this
afternoon and evening, when the passage of the sfc cold front will
trap enough moisture below an elevated inversion layer.VFR
conditions are expected by Tuesday morning as drier air and
increasing sfc high pressure will erode the MVFR deck by early
Mixing and a tight sfc gradient associated with the approaching cold
front will keep wind gusts in excess of 20kt through this evening.
The frontal passage will shift wind from the wsw to the nw, with the
ensuing sfc pressure rise causing the wind to taper off tonight.
Vfr will prevail through much of the week, with possible restrictions
after Wednesday due to occasional disturbances bringing rounds of

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
