Short term (today and tonight)
issued at 356 am mdt Mon jun 26 2017
an upper level ridge will shift east across the western states
today. By 00z Tuesday, the axis will be along the colorado-utah
border. This will bring warmer and drier air to the area today.

Low clouds patchy fog over lincoln, elbert, southern douglas, and
park counties will burn off by mid morning. Elsewhere, mostly
clear skies are expected through mid afternoon. Cumulus clouds
will form over the higher terrain during the afternoon. Soundings
show a cap around 600mb, so it will limit thunderstorms
development. Appears the only chance for storms will be along and
south of interstate 70 where the least CIN and best instability
will be. If any storms form, they are expected to be high-based
and produce gusty winds to 40 mph and light to moderate rainfall.

With the warmer airmass moving in and less cloud cover, it will be
warmer today with highs in the lower to mid 80s across northeast
colorado.

Long term (Tuesday through Sunday)
issued at 356 am mdt Mon jun 26 2017
on Tuesday... The upper ridge of high pressure shifts east into
the central plains states... With a moderate westerly flow aloft
over colorado. Gusty winds to 30 mph combined with low relative
humidity and dry fuels will result in high fire danger across the
mountain valleys. Therefore... A fire weather watch has been
issued for those areas from noon to 9 pm. In addition... A
downslope flow will produce hot and dry weather across the front
range urban corridor and adjacent plains... With temperatures
climbing into the mid 90s. Further to the east... A moist south to
southeasterly flow ahead of a surface lee trough... Combined with
an upper level disturbance... Will result in widely scattered
afternoon and evening thunderstorms. Higher CAPE values of over
1500 j kg combined with ample directional shear could result in
some of the storms becoming severe across the far northeastern
corner of the state.

On Wednesday... Cooler temperatures are expected as a weak cold
front moves across northeastern colorado. Moisture behind the
front seems somewhat limited. However... A 60kt+ jet sagging south
across the CWA may aid in some showers and thunderstorms during
the evening hours.

Thursday through Saturday... An upper level low pressure system
will move from saskatchewan canada into the northern plains
states. Colorado will remain under the influence of a northwest
flow aloft with occasional upper level disturbances and weak cold
fronts moving across the area. As a result... Slightly below normal
temperatures along with isolated to scattered showers and
thunderstorms are expected both days... Most numerous across the
far northeastern plains.

The GFS and ECMWF diverge somewhat by Sunday... With the gfs
showing a weak trough over the great basin... While the ECMWF tries
to build an upper level ridge over the rocky mountain region. The
ecmwf solution brings warmer and drier weather to north central
and northeastern colorado... While the GFS is cooler and wetter.

Since this is all the way out in day 7... Have decided to keep the
near normal temperatures and slight chance of pop given by
forecast builder.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 356 am mdt Mon jun 26 2017
no aviation issues expected. Some mid and high clouds are
expected to form after 18z at heights above 8000 feet. Southerly
drainage winds will turn easterly after 18z and then return
southerly by 06z Tuesday.

Bou watches warnings advisories
Fire weather watch from Tuesday afternoon through Tuesday
evening for coz211-213-214.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
