Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (this evening through Saturday)
issued at 148 pm mdt Fri aug 18 2017
main forecast issue will be onset of thunderstorms and associated
hazards Saturday afternoon. Winds will become light and variable
with the winds staying the lightest in the eastern portion of the
area the longest. With lower dewpoints, no cloud cover, and recent
biases, undercut guidance a little in the eastern portion of the
Lee trough dryline develops or moves to near the colorado border
during the mid and late afternoon hours. Shortwave trough will move
over the top of this surface feature at the same time. So expect
thunderstorms to develop in this area. However, guidance over all
and especially the high resolution guidance differs on where
initiation will be with convective feedback issues causing problems
with the nam. So confined the pops mainly to the western half to two
Most of the area is in a marginal risk. Severe parameters indices
would support this and even expand it through most of the area. Also
precipitable water values increase into the 1.5 to 2 inch range. So
locally heavy rainfall definitely be a threat. For high temperatures
current guidance supports warming the maxes to near what the
previous forecast had so adjusted accordingly.
Long term (Saturday night through Friday)
issued at 151 pm mdt Fri aug 18 2017
Saturday night and Sunday: nearly zonal flow aloft will prevail
through early Sunday. High pressure slides east, out of texas and
into the southeastern states late in the day, adding a slightly
monsoonal tendency to the upper flow across the four corners region.
This will assist in maintaining relatively high moisture levels
across the cwa. Not expecting much in the way or precipitation and
any thunderstorm activity would be isolated due to lack of upper
Monday (day of the eclipse): for Monday, a shortwave will take shape
in the lee of the rockies. GFS soundings indicate increased moisture|
levels at both the 700mb level and the 500mb to 300mb layer.
Condensation pressure levels are generally over 80 mb through the
afternoon, thus cloud cover will be dependent upon how fast the
shortwave develops and enhances the theta-e boundary. Once this
boundary forms, we will see increased cloud cover and thunderstorm
chances especially for the eastern two thirds of the cwa, otherwise,
scattered and variable cloud cover is likely with coverage
increasing during the early afternoon.
Tuesday through Thursday: the upper pattern becomes amplified as we
head into Tuesday. High pressure forms and extends into the northern
plains with low pressure over both the eastern portions of the great
lakes region and the southern reaches of british columbia. Look for
isolated thunderstorm chances at best each day as the ridge
dominates the pattern.
Friday: model guidance varies greatly heading into Friday as the gfs
develops a closed low in the four corners region. This will move
through southeast colorado and across western kansas going into
Friday afternoon. CAPE will be approaching 2500 to 3000 j kg per gfs
guidance with deep layer shear upwards of 45 knots. If the guidance
remains consistent, we could see scattered severe thunderstorms and
very heavy rainfall.
Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1117 am mdt Fri aug 18 2017
vfr conditions are expected through the period. Winds will start
out near 10 knots from the north then shift to the northeast
during the afternoon and decrease by about 5 knots. During the
night the winds will become light and variable before shifting
the south at near 8 knots.

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.
