.SHORT TERM...(Today through Friday)
Issued at 233 AM MDT Wed Mar 29 2017

Low pressure that brought us the widespread rain and snow
yesterday now located in eastern New Mexico. Upper diffluence area
has shifted off to the southeast and can be seen quite noticeably
on mosaic radar with echoes in Nebraska moving east and those in
Colorado moving southwest. With this diffluence moving out of our
forecast area, went ahead and cancelled remaining advisories
early. Still getting some very light snow here at the office, but
it has been really decreasing as well.

Water vapor imagery showing a ridge of high pressure just off to
the northwest this morning. Expect this ridge to build over the
area through the day with all precip ending by sunrise across
southeast Wyoming. Southern Panhandle looks to be the last area to
end and that looks to be mid morning or so.

Next system to impact the area being advertised for Thursday night
into Friday. Low taking a similar track to this past storm,
tracking across New Mexico during the day Friday. Expecting
similar weather with this system as we saw with this past low.
Mostly rain with mountain snow. 700mb temperatures very similar,
so would have to say this one will be mainly rain as well.

.LONG TERM...(Friday night through Tuesday)
Issued at 233 AM MDT Wed Mar 29 2017

Rather active pattern looks to persist over the region with a
couple more upper systems affecting the CWA this period. Models in
pretty good agreement overall though some track differences mainly
with the second system. The first upper low will drift east from
the 4 corners area Friday night through Saturday night bringing
rain and snow to mainly the southeast part of the CWA. A cool day
expected for Saturday with snow possibly reaching into the higher
plains mainly Saturday morning. Pcpn should end late Saturday as
the system moves farther southeast and short ridging moves over
the CWA. Dry and warmer Sunday into Monday then the next upper low
begins moving into the region by late Monday...passing by on
Tuesday. EC farther south with the track of this system and colder
as well with more widespread pcpn so will have to watch how this


.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
