Issued at 1224 pm mst Fri jan 18 2019
the winter weather advisory remains in effect for the eastern
sector and has been expanded to include yuma, kit carson,
cheyenne (co) counties in colorado and sherman county in nw
kansas until 11 pm mt 12 am ct. Confidence is marginal that
conditions will be widespread, however, the likelihood of
localized areas becoming affected by blowing snow and or ice
accumulation. With winds expected to gust upwards of 30kt, blowing
snow is a concern, especially for kit carson and cheyenne (co)

Reports of freezing fog and ice accumulations have come from the
far eastern counties earlier in the day and are currently
occurring in the western counties. Burlington is reporting one
quarter mile visibility due to freezing fog as of 12:40 mt.

Visibilities are already dropping in sherman county as well.

Short term (today through Sunday night)
issued at 211 am mst Fri jan 18 2019
across the tri state region this morning... Low level stratus and fog
continue to creep slowly westward along a meandering frontal
boundary. Only areas for the most part not affected by the veil of
low clouds and fog are locales along west of highway 27 where mostly
clear conditions prevail... For now. Low level surface flow east of
the surface boundary is out of the sse and areas west... A mix of
light variable and westerly. The veil of clouds is affording the cwa
temperatures in a range from the upper 20s into the lower 30s.

Going into today... The entire CWA will see low clouds with fog
continue to push west towards the co ks border. An 850 surface low
is sliding SE off the front range along the front... And with strong
surface ridging to the east... This low combo will track towards sw
kansas and eventually east of the CWA during the day today. The
upper low associated with the lower level features is currently
moving thru the central rockies and will move into the central
plains later today.

As with previous guidance... The track of these systems will leave
the CWA on the low side of expected qpf. Any east-southeast flow
currently over the CWA is expected to transition to a northerly
fetch by midday as the surface low shifts towards central kansas.

Bufkit soundings continue to show main p-type as a mix of
sleet rain freezing rain... Along with some light snow(mainly late as
colder air arrives). The passage of the surface low by midday will
afford the region fluctuating temps above freezing before a
transition to a colder airmass on the northerly flow. This scenario
combined with fog freezing fog around the CWA will allow for the
current winter weather advisory to remain in place. These affected
zones(ne locales) have the best chance to see accumulating
precip... Up to an inch of snow along with a few hundredths of an
inch of ice from any freezing rain. The remainder of the CWA will
see light mix mentioned above with no expected accum.

The arrival of the strong northerly winds later today will afford
some areas seeing light snow... Blowing snow potential as gusts could
reach the 35-45 mph range. With the upper low exiting the CWA this
evening... Expecting precip to taper fairly quickly from west to east.

Friday night and on thru the upcoming weekend... The CWA will see dry
conditions as strong ridging builds over the rockies into the
western plains.

For temps... Highs today mainly in the 30s as colder air wraps into
the CWA by midday. Saturday... Highs in the west will be mainly in
the 40s... And mainly 30s east. The difference due to snowpack on the
ground. By Sunday... Temps will range from the upper 40s east to
almost 60f in NE colorado. Overnight lows will drop into the teens
tonight but increase over the weekend into the 20s.

Long term (Saturday night through Friday)
issued at 133 pm mst Fri jan 18 2019
heights rise over the weekend into early next week as an upper ridge
progresses across the rockies and plains, yielding dry weather and
warming temperatures. After a dry day on Monday, a trough digs into
the region and generates precipitation Monday night into Tuesday
morning. At this time, precipitation is anticipated to begin as rain
as it moves in from the west before transitioning to snow through
the evening. Only light accumulations are anticipated at this time.

However, with northerly winds forecast to increase during this
timeframe (gusts up to 45 mph possible) will need to monitor for
blowing snow limited visibility concerns.

Dry conditions return midday Tuesday and continue into Wednesday,
with winds decreasing Tuesday evening. Another disturbance pushes
across the high plains and produces a slight to low chance of light
snow Wednesday night into Thursday. Little to no accumulation is
currently forecast. Northwest flow develops aloft on the backside of
the trough as it shifts east at the end of the work week.

The warmest temperatures of the long term are expected on Sunday
with highs in the mid 40s to upper 50s across the region. By
Tuesday, temperatures drop into the 30s before rising into the upper
30s low 40s for the remainder of the period. Low temperatures range
from the mid teens to upper 20s.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1036 am mst Fri jan 18 2019
a wintry mix is expected to impact both terminals. A rain snow
mix is more likely for kgld than for kmck, which is more prone to
a snow freezing rain threat. Another concern for this TAF period
is the gusty winds. Winds will gust upwards of 30-35kt for most of
the day into the evening. Ceilings will be low and are expected
to remain low most of the TAF period as there is extensive cloud
cover upstream. Confidence in the wintry weather types is moderate
as it will ultimately depend on the temperatures at the time the
system moves through the area. Weather types were included to
provide a "heads up" to the potential for them to exist.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
