Short term (this evening through Thursday)
issued at 258 pm mst Wed nov 14 2018
weak upper level ridge will continue to slide southeast of the area
tonight in the northwest flow aloft. An upper level trough moving
across the northern plains will push a cold front south across
eastern colorado Thursday morning. Not a lot of cold air behind this
front. Expect highs a little cooler than today with northeast winds.

Ahead of this cold front, a weak lee side trough will help bring
breezy conditions to the foothills and east slopes of the front
range mountains tonight. This will help keep temperatures mild
tonight. The airmass will stay dry with clear mostly clear skies
expected through tomorrow. Like this morning, expect the open water
of lake granby to produce localized fog. Added this to the otherwise
quiet weather forecast.

Long term (Thursday night through Wednesday)
issued at 258 pm mst Wed nov 14 2018
strong zonal jet-level flow rounding the top of a high amplitude mid-
tropospheric ridge off the pacific northwest coast is progged to
curve southward, driving a shortwave trough southward over southern
british columbia on Thursday, and down over montana and wyoming on
Friday. A tight baroclinic zone associated with a 100-120kt speed
maxima forming on the bottom side of this southward progressing wave
appears to generate a wide band of light to moderate snowfall across
wyoming on Friday, with help from a sfc cold front and relatively
moist sfc-700mb northeast flow. Synoptic scale forcing and moisture
appears best on the gfs, and least on the canadian model.

Gfs, nam, ECMWF and canadian models show jet-induced baroclinicity
and precipitation shifting south over southern wyoming Friday night
behind a leading sfc cold front which most models show sliding south
across nern colorado during the evening. GFS and ECMWF show a shift
to northeast winds with frontal passage at denver around 03z
Saturday. Even with leeside upslope flow expanding southward behind
the front, models hold off on generating any QPF over and along the
front range until Saturday, and only up along the wyoming border
during the early to mid-morning hours according to the fast gfs. As
the tail end of the jet sags south over northeast colorado on
Saturday, all models show the jet weakening and its core passing
just east of the state, consequently causing sfc-500 mb QG ascent to
weaken over the forecast area. Meanwhile, models indicate a gradual
drop off in upslope wind speeds the farther south you go along the
front range, with hardly any upslope flow indicated in the palmer
divide area. At the present, QPF with this storm appears light and
concentrated over and near the front range, with the greater amounts
over the higher terrain in larimer and boulder counties. Even
here, snow amounts may end up being no more than 3-6 inches, and
that may be on the high side. Could see a second area of banded
snowfall on the plains out around the washington logan county area
Saturday afternoon and evening with the tail end of the 50-60kt
jet passing overhead. Snow amounts probably no more than a couple
inches out there. Otherwise, temperatures other big change with
this passing system with above average temps on Thursday dipping
well below on Saturday. For instance, plains temperatures in upper
50s lower 60s Friday, expected to drop to the upper 20s 30s on
Saturday.

Sunday, the CWA comes under the influence of strong subsidence and
much drier air. Should see rapid clearing in the morning as well as
a modest jump in temperatures.

Monday through Wednesday, ridging out west and a relatively dry
northwest flow over the region should keep conditions dry and
seasonably mild. Can't rule out a few orographic snow showers over
the northern mtns on Monday. Otherwise, it'll be dry in the high
country during the period.

Aviation (for the 00z tafs through 00z Thursday evening)
issued at 258 pm mst Wed nov 14 2018
light winds at kden are expected to become a southerly drainage
direction this evening, around 02z. A weak cold front will back into
the denver area Thursday morning bringing northeast winds by 18z.

Skies will remain mostly clear with just a few high clouds through
Thursday.

Bou watches warnings advisories
None.

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.
