311 pm mdt Mon oct 23 2017

Short term (this evening through Tuesday)
issued at 311 pm mdt Mon oct 23 2017
high pressure at the surface and aloft are building over colorado
this afternoon and tonight which will result in a continuation of
dry and seasonal weather. The northerly flow will be bringing in
cooler air, but as heights gradually rise, surface temperatures
will be warming a few degrees. Skies will be mostly clear through
the next 24 hours. The clear skies and dew points in the lower 20s
will allow overnight temperatures to drop to the lower 30s on the
plains, and cooler at higher locations. Afternoon highs tomorrow
should climb to around the 60 degree mark. Winds aloft are
expected to be lower than today, and more out of the north than
northwest. This will lead to the higher mountain ridges being the
main places to see any gusty winds.

Long term (Tuesday night through Monday)
issued at 311 pm mdt Mon oct 23 2017
for Tuesday night and Wednesday, the flat upper level ridge
pushes east across the forecast area. Warm advection continues, and
with nearly full sunshine and enhanced downslope through the day
we should see strong mixing. A few plains locations may be pushing
80f as 700 mb temps warm to near 10c. Surface gradients increase
through the day so some gusty winds should be able to spread
across the plains. Fire danger will also increase but wind speeds
are not expected to reach critical levels at this point. Foothills
may be closer.

Main focus continues to point toward the change in the weather
Thursday. Front will likely arrive in the early morning hours, so
have knocked high temperatures back a few degrees and went with
slowly falling temperatures through most of the day. May end up
being even cooler. With regard to precipitation, it is a fast
moving system, upslope is noted to be quite shallow, and upper
level dynamics may be rather weak. Therefore, it continues to
look like a light precipitation event and mainly right near the
front range mountains and foothills. Temperatures from the surface
through 700 mb appear cold enough for some light snow
accumulations in the higher terrain, and possibly a rain snow mix
for the i-25 corridor.

Friday is still looking chilly but dry, then a gradual warming and
drying is expected for the upcoming weekend. The next potential
fast moving short wave or front may arrive sometime early next
week in northwest flow aloft.

Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 311 pm mdt Mon oct 23 2017
only minimal aviation impacts through the next 24 hours. North to
northeast winds are expected to continue through the evening,
until drainage winds kick in overnight. The airmass is dry with
high pressure developing at the surface and aloft. North to
northeast winds are expected again by tomorrow afternoon.

Bou watches warnings advisories
None.

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.
