Area Forecast Discussion
National Weather Service Goodland KS
509 AM MST Sat Dec 1 2018
.SHORT TERM...(Today through Monday night)
Issued at 443 AM MST Sat Dec 1 2018
Main forecast concern will be current storm system affecting the
area. Satellite showing an amplified and active pattern from the
Pacific into North America. Within this flow, there is a split flow
from the north central portion of the country into the southern
plains. Currently elongated/closed off negatively tilted system near
the Kansas/Oklahoma border is now starting to eject to the
northeast.
Models started out fine at the jet level. At mid levels the Ecmwf
and Nam were doing a little better than the Gfs. Once again the
models changed their tune and now incorporate a little of the runs
from my previous two shifts. System is elongated with a few other
smaller scale circulations other than the main southern one. This
has prevented any appreciable precipitation to move around the
backside of this system. Also the models are a little further south
with the main circulation from yesterday. Also the models are
ejecting the system more northeast.
Today through Sunday...As stated above the system is beginning to
kick out. However during the middle of the day, the models
temporarily stall system in north central Kansas before moving
eastward.
A few disconcerting facts raise some doubt on whether we receive any
significant snowfall. Upper air and surface analysis would
indicate that there is not a lot of cold air with this system.
There is colder air much further upstream but am wondering by the
time it gets here the air mass will be much drier than it is.
Also the analysis shows that the dewpoints/wetbulbs at low levels
are above 32 degrees with continued moisture advection still
occurring from the southeast. With the exception of the DEN sounding
which looks to have ice in the column, but is not saturated, there
appears to be no ice in the column until later on in the day. There
has been some change over to snow. But observations upstream have
been switching back and forth between rain and snow.
Large scale and mesoscale forcing are moderate to strong. However
theta-e lapse rates are not very low. So expect a long duration snow
event into Sunday. Believe it will be mostly light. However, an
occasional moderate band of snow may occur with the stronger
mesoscale forcing.
Saying all that, decided to cancel the southern most row of counties
from the Winter Weather Advisory since this area has not received
any snow yet, and will not change over to snow until later today.
Kept the remainder of the advisory going with 2 to 4 amounts. The
upper end of the range, and possible locally higher amounts, will be
along the Kansas and Nebraska border.
Winds have increased. The higher winds speeds 20 to 35 mph with
gusts possible reaching 50 mph will be over the southwest half. Will
have to watch higher gusts that some guidance is hinting at. With
the exception of Yuma county, the remainder of the advisory area
will sustained winds and gusts about 10 to 20 mph less. So do not
expect a significant amount of blowing and drifting snow at this
time.
For high temperatures kept the cold temperatures given to me by the
blend or lowered them a little.
Sunday night...Light snow will end with little to no accumulation.
No changes were made to what the forecast builder gave me.
Monday/Monday night...Dry conditions expected along with much
colder/below normal temperatures. Did not make any changes to what
the builder gave me. However, this will need to be looked at again
depending how extensive the snow is.
.LONG TERM...(Tuesday through Friday)
Issued at 150 AM MST Sat Dec 1 2018
Northwest flow aloft prevails into the extended period, with
troughing to the east of the High Plains and an upper ridge building
along the west coast. Dry weather is forecast Tuesday through
Thursday as the ridge gradually progresses towards the region. On
Thursday, a disturbance to the north flattens the ridge while a
short wave trough advances from the desert southwest to the southern
Plains. This disturbance currently generates chances for light snow
on Friday, mainly south of Interstate 70. Overall, the majority of
the precipitation produced by this wave is forecast to stay south of
the region. Will continue to monitor in the coming days.
High temperatures warm slightly into the 30s on Tuesday, and again
into the mid 30s to low 40s on Wednesday. However, an arctic front
should drop temperatures back into the upper 20s to mid 30s on
Thursday and Friday. Low temperatures generally remain in the teens.
