Short term (today and tonight)
issued at 419 am mdt Sun aug 25 2019
only minor changes to the forecast this morning as the plan for a
warmer day with windy conditions in the mountains looks good.

There is still some moisture hanging out along the eastern border
with some low clouds and maybe some patchy fog east of sterling
and akron for a few hours this morning. There are also some high
clouds on the nose of the jet pushing across the northern rockies.

These will be over our area this morning then slide eastward this
afternoon, so they shouldn't affect today's high temperatures.

The other change was more wind over the higher mountains. We've
already seen gusts over 50 mph above timberline this morning.

The rest of the forecast is in order, with winds mixing to the
surface later this morning and what remains of the moisture mixing
out. There will be less wind and less drying over far eastern
colorado, but it should still dry enough to prevent convection.

There's a slight chance of some convection brushing the northeast
corner with the cold front late tonight.

Long term (Monday through Saturday)
issued at 419 am mdt Sun aug 25 2019
temperatures on Monday and Tuesday drop to around 80 as a couple
of cool fronts push into the front range from the northeast. The
first will push into the urban corridor late tonight with the next
one expected to move into the northeast plains Tuesday morning.

Along and west of the continental divide, a dry northwesterly
flow will prevail with little if any thunderstorm coverage. From
the foothills eastward however, weak low level easterly surges
will provide enough moisture for a slight chance of showers or
thunderstorms Monday night and Tuesday. Temperatures will rebound
by the middle of the week as the upper level ridge builds over the
central rockies. Highs on Wednesday and Thursday will climb back
around 90. Increasing subsidence aloft will less than chance of
thunderstorms with a weaker northwesterly flow aloft as well.

Friday and Saturday, another system and an associated cold front
will bring cooler temperatures and a better chance of
thunderstorms the region. The best chance of thunderstorms will be
from the foothills and palmer divide eastward across the
northeast plains Friday and Friday night.

Aviation (for the 06z tafs through 06z Sunday night)
issued at 419 am mdt Sun aug 25 2019
vfr through tonight. West winds will develop over the denver area
by 15z and become more northwesterly by 18z with gusts of 20 to 25
knots expected. There may be another period of west winds between
00z and 04z, but speeds are expected to be diminishing at that
time, then winds should go more southerly.

Fire weather
Issued at 419 am mdt Sun aug 25 2019
increasing winds will lead to red flag conditions by midday over
the mountains. Gusts in the 30-40 mph range will be common with
humidities dropping to around 15 percent. Along the cheyenne ridge
it will be a bit less windy, but with lower humidities. Other
areas will also be near red flag criteria. Further south on the
plains, it will be pretty dry but with wind gusts in the 15-25 mph
range. Finally, the higher mountains will have higher humidities,
in the 15-25 percent range, but very strong winds with gusts
between 40-60 mph this afternoon.

Monday and Tuesday, the fire danger will remain elevated at times
primarily in north, middle and south parks due to the persistent
dry conditions. Less wind and cooler temperatures elsewhere will
lessen the fire danger.

Bou watches warnings advisories
Red flag warning from 11 am this morning to 8 pm mdt this
evening for coz211-213>215-238-242.

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.
