Short term (today and tonight)
issued at 408 am mdt Mon oct 15 2018
goes-16, webcams, and surface obs are showing shallow radiation fog
across the fort collins loveland greeley area, especially in the
low-lying areas. The hrrr had this pretty well pegged. Visibility
could be reduced to 1 4 mile or less in a few areas along us-34
and i-25 during the morning commute so please be ALERT to patches
of fog. Expect the Sun to burn off the fog by 9am or so.

The upper flow pattern will be benign across colorado with a cut-
off low spinning well southwest of us across arizona, and the
polar jet well north of us across southern canada. The flow at 700
mb is out of the northwest through tonight, but it will actually
begin a period of warm advection, warming temps 6-8 degc in that
layer through tonight. Significant drying aloft will continue
today into tonight, resulting in zero precipitation chances area-
wide and mostly sunny skies. While it will definitely be a lot
warmer than Sunday, temperatures will remain well below seasonal
normals today without the aid of true downslope warming. Areas
that received 6-8 inches of snow like boulder to fort collins will
also see a slightly slower warm up as snow cover will hang on
longer in those areas. Expect around 40 degrees for the deeper
snow cover areas and mid 40s elsewhere across the plains. The
mountains will remain seasonably cool with highs in the upper 20s
to 30s as 700 mb temps remain between -3 and -5 degc.

Tonight will be clear and cold once again, though with the warming
aloft and the loss of snow cover across much if not all of the
plains, lows will not be quite as cold and generally stay in the
20s, with teens expected in the mountains and high valleys.

Long term (Tuesday through Sunday)
issued at 408 am mdt Mon oct 15 2018
a generally tranquil autumn weather pattern will prevail over the
forecast area through next weekend. The only weather maker will
be a closed low that moves up from the deep desert southwest, but
then shears out as it lifts across the great basin and central
rockies Wednesday and Thursday. That system appears to carry
enough mid level moisture to bring an increase in clouds from the
southwest by Wednesday, and perhaps a few showers as far north as
summit county. Thursday could see a few more light showers across
the mountains, before a stronger blocking ridge develops across
the spine of the rocky mountains through next weekend.

The net result will be an extended period of moderating
temperatures, and a return to near normal readings by Thursday and
Friday. Readings should be able to reach slightly above normal
levels by this weekend. Finally, a week of true autumn weather
ahead.

Aviation (for the 06z tafs through 06z Monday night)
issued at 408 am mdt Mon oct 15 2018
vfr and light winds into Thursday with no aviation impacts
expected. Drainage winds should occur again tonight but remain
less than 10 kts.

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.
