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.

958 am edt Mon may 20 2019
Dry weather is expected through mid week under high pressure. Rain
chances return Wednesday evening.
Near term until 6 pm this evening
Late morning update:
no major changes have been made to the forecast.
an advancing cold front will push through our region during the late
afternoon. Drier and cooler air will work in behind the front as sfc
high pressure begins to build, which will lead to near normal high
temperature. Enough daytime heating mixing plus a tighter sfc
gradient will lead to gusty late morning to afternoon west to
Short term 6 pm this evening through Wednesday night
Dry and cooler weather is expected Tuesday as high pressure
continues to build under the broad upper trough across the NE conus.
A transition to ridging plus sfc high pressure will maintain dry
weather for much of Wednesday, with temperature returning to above
A shortwave ridge is progged to traverse the upper level high
Wednesday 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 SE CONUS through the
weekend. Waves occasionally rotating through the northern periphery
of the high should result in periodic shower and thunderstorm chances
through the period. Above average temperature is expected.
Aviation 14z Monday through Friday
Patchy MVFR CIGS will lift by this afternoon due to diurnal heating
and the eventual passage of the sfc cold front. Heating plus a tight
sfc gradient will generate wind gusts in excess of 20kts by the
afternoon, first out of the W then shifting out of the nw. The
encroaching sfc high pressure will cause winds to taper off tonight.
Medium confidence that enough moisture will remain stuck under an
elevated inversion layer for MVFR CIGS to return this evening under
nw flow. Increased subsidence and a shift towards ridging should
erode this deck during the overnight hours.
Vfr will prevail through much of the week, with possible restrictions
after Wednesday due to occasionally shortwave brings 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.
