Short term (this evening through Thursday)
issued at 342 pm cst Wed feb 20 2019
the weather has quieted down today in the wake of the storm system
which brought widespread accumulating snow yesterday evening last
night. The highest snow amount of 5-6 inches inches were in
valley greeley counties in the ord and greeley areas, with
additional high totals around 6 inches in north central kansas in
the victor area (mitchell county).

The weather remains quiet tonight in between weather systems with
mainly clear skies and light winds. With good radiating conditions,
have some concern for the development of fog with the new snow,
however high resolution models are not picking up on visbility
restrictions and will have next shift monitor trends.

Attention then turns to the next approaching system deepening along
the western conus. Ahead of this next system, flow aloft transitions
southwest across the plains Thursday. In increasing isentropic
lift warm air advection Thursday afternoon, light snow development
is possible primarily across western northern zones. The GFS is
pretty aggressive with its potential snow amounts, suggesting 2-3
inches are possible but this is high compared to other models and
currently have some amounts of an inch or so in the ord greeley
areas, tapering off to the south toward the platte river.

Temperatures have been kept conservatively cool Thursday due to
increasing cloud cover precip potential and easterly wind
component.

Long term (Thursday night through Wednesday)
issued at 342 pm cst Wed feb 20 2019
the weather is messy with the approaching upper low heading into
Friday. Low level moisture is on the increase with low
clouds stratus developing Friday and continued lift in the warm
air advection regime will lead to more light precip. Depending on
how quick we see the moisture come in, fog may need to be added
to the forecast Thursday night Friday morning.

Friday's light precip should start as freezing drizzle in the
morning, then transition to drizzle (liquid) as
temperatures dewpoints rise. A little snow could mix in at times
in the north portion of our forecast area if the dendritic layer
sees some saturation. Little if any snow ice accumulation is
expected.

A potent upper low winter storm system is still targeting the
central plains Friday night Saturday, however models have trended
farther south with the storm system track today compared to 24
hours ago. The upper low is forecast to lift northeast from new
mexico texas panhandle Saturday morning, then track towards
wichita and on into NW missouri during the day.

The 12z GFS tracks the system farther NW compared to the
ecmwf gem and the storm track will be key in determining where
brunt of heaviest precip will be as well as precip type. Have
maintained the ensemble solution for now... Which is also trending
toward the more southern solution with the heavier snowfall now
oriented across our southeast counties. Precip type will likely
begin as a messy mix of rain freezing rain sleet snow, before
changing to snow west east Saturday as cold air is drawn in on
the back side of the system. The arrival of cold air and abrupt
transition to snow looks to be accompanied by intense northwest
wind gust over 40 mph. Abundant moisture is available with this
system and snow amounts will be dependent upon the timing of the
change from rain wintry mix to snow and the system track. The
current forecast has snow amounts of 2 to 5 inches, but any snow
will be difficult to measure due to the expected winds.

Also... Instability is not far away in ks and will need to monitor
for possible convection. Stay up to date on the latest forecasts
regarding the storm track and potential impacts from the
approaching storm.

The system moves out quickly Saturday night with dry weather Sunday.

The remainder of the extended continues to reflect cooler than
normal temperatures and intermittent chances for light snow.

Aviation (for the 18z kgri kear tafs through 18z Thursday)
issued at 1101 am cst Wed feb 20 2019
quiet weather withVFR conditions are forecast through the taf
period. Cloud cover has decreased behind a departing storm system
which produced snow last evening night. Minimal clouds are
forecast until the latter TAF hours Thursday when clouds increase
again ahead of another approaching upper low pressure system. Look
for west winds around 14kts to become light variable tonight.

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.
