Update
Issued at 846 pm mst Tue jan 16 2018
under clear skies, the higher mountain valleys and parts of the
eastern plains are radiating quicker than forecast. Have adjusted
some of the minimum temperatures downward tonight in these areas.

Other than that, the ongoing forecast is good.

Short term (this evening through Wednesday)
issued at 311 pm mst Tue jan 16 2018
another night of cold temperatures, but not as cold as last
night. Bitter cold air also trapped in the mountain valleys.

Lighter and slightly warmer flow will once again produce strong
surface based inversions producing pockets of especially cold air
such as along river bottoms. Otherwise, clear skies and light
breezes overnight with flat cross area pressure gradient.

On Wednesday, flow aloft turns northwesterly and remains quite
dry. A weak ripple in this flow marking the leading edge of
significantly warmer aloft is fcst to pass over the fcst area
with a narrow band of mid and high-level moisture late in the day.

Gradient winds east of the mtns also becomes downslope, to help
warm temps. Highs tomorrow anywhere from 12 to 18 deg f warmer on
the plains and 6 to 12 deg f warmer in the high country.

Long term (Wednesday night through Tuesday)
issued at 311 pm mst Tue jan 16 2018
warm air advection will bring warmer temperatures to the forecast
area through Friday. Highs will warm to near 60 degrees f on the
plains and around 40 degrees f over the mountains.

Currently, models are moving a winter system into the northern
mountains Saturday associated with high QG values showing ample
ascent. GFS moves the system in faster with snow on the plains by
late day Saturday. The european moves the system slower with
widespread coverage over the plains Sunday, matching well with
the canadian solution. The GFS has the system exiting the state 6
to 12 hours sooner than the others. For this reason pops at the
beginning of the system have remained the same as previously
forecast, while the end of the storm has been increased to match
the canadian and european. The highest QG appears over the east
central colorado plains Sunday as the european brings a closed low
northeast in colorado.

To start next week, westerly flow will dominate the forecast area
as another system moves in from the west coast. Moisture could
accompany this westerly flow, bringing possible snow chances to
the mountains Monday.

Aviation (for the 18z tafs through 18z Wednesday afternoon)
issued at 846 pm mst Tue jan 16 2018
dry and stable conditions will produceVFR conditions under mostly
clear skies for the next 24 hours. Winds will remain
southerly drainage through the night, with speeds generally under
10 kts. Tomorrow, southerly winds 4-8 kts in the morning turn
counter- clockwise to east- northeast 7-13 kts by early to mid
afternoon, except along the foothills where light west-northwest
winds will develop after 20z - though these may not affect bjc
where light easterlies are expected to push into.

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.
