Short term (this evening through Wednesday)
issued at 300 pm mdt Tue mar 19 2019
cold upper level low spinning over western nebraska is helping to
produce the convective cumulus field across the forecast area as
the trough axis passes over. Surface high pressure over wyoming is
pushing gusty north-northwest winds across the plains, turning
northeasterly upslope near the front range foothills to create
weak rain snow showers. It is pretty dry out there, so not too
much more than virga or a trace of snow, though temperatures in
the mid 40s will quickly melt it, if it was able to fall as snow.

Could see a little bit more over the foothills and ridge of the
palmer divide, but not more than an inch. A few stronger showers
over the northeastern plains may cause some restrictions in
visibility with up to half an inch of snow. All this activity
should die down by sunset, with skies clearing from the northwest.

This will allow temperatures to cool quickly, with some very cold
spots expected in the high mountain valleys. The northwest winds
over the east plains will likely stay a bit breezy into the
evening hours before decreasing, but should see the normal cold
spots near greeley and limon.

Expect clear skies Wednesday and temperatures about 10 degrees
warmer for a nice spring day on the vernal equinox.

Long term (Wednesday night through Tuesday)
issued at 345 pm mdt Tue mar 19 2019
meridional flow will setup across much of north america during the
long term period. A strong, digging trough over the northeast u.S.

Will stall the flow across the western u.S. Through the beginning
of the weekend. Consequently, a trough which will move onshore
over california tonight will slow as it moves over the four
corners region Thursday night. This system will bring a chance of
rain and snow showers to the mountains during the late afternoon
on Thursday through Saturday morning. Due to the higher snow
levels of up to 9000 feet at times, snowfall amounts will be on
the light side with the highest amounts in and near the mountains
of summit county. A shortwave trough will rotate around the base
of the larger scale trough on Friday which will provide enough
forcing to create rain showers and a few thunderstorms across the
eastern plains. Models are indicating dew points getting into the
low 40s across the far eastern plains and with relatively cold mid
level air associated with the trough moving over the area, there
may be some instability and small amounts of cape. No severe
weather is expected but some people who live on the eastern plains
will be hearing thunder for the first time in 2019. Some models
indicate over an inch of rain could fall in a couple locations but
there is low confidence in that at the moment.

Westerly flow over the weekend will keep a chance of lingering
snow showers going in the mountains before the next system arrives
from the west. A high pressure system moving southward over the
northern plains early on Monday will shift the low level winds to
the northeast as colder air moves in. With the colder, upslope
flow at the surface and a trough moving overhead, rain and or
snow showers will be possible across much of the CWA Sunday night
into Monday. There is low confidence in this system as models
disagree on its strength.

Aviation (for the 18z tafs through 18z Wednesday afternoon)
issued at 300 pm mdt Tue mar 19 2019
isolated showers are pushing southeast over the area currently,
which are still expected to be short lived, and likely a mix or
rain and snow with temperatures in the upper 40s. Drier air moves
in from the north after 00z with mostly clear skies expected by
06z. Northerly winds will be gusty through 01-02z before quickly
decreasing and switching to drainage overnight. Light winds will
switch to northwest Wednesday morning before becoming northeast in
the afternoon. All winds after 02z tonight should remain less than
7 kts.

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.
