AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1225 AM MDT Sun Apr 28 2013

.UPDATE...
Ended the high wind warning for most locations but extended it until
3AM for the Northern Rocky Mountains and Cut Bank areas as winds are
still a bit strong and gusty.

&&

.AVIATION...
UPDATED 0440z.
The main weather problem will be winds. westerly winds have
diminished and should diminish a little more after midnight. A
Canadian cold front will spread into the u.s. route 2 area after
midnight. Feel pretty confident it will affect KHVR and KCTB but
have low confidence what the wind directions will be after frontal
passage into the morning. In any case winds at those two stations
should become gusty out of the west by afternoon. Elsewhere westerly
winds will increase during the afternoon but should not be as strong
as those on Sunday. There might be little if any dropoff with wind
speeds Sunday evening. Scattered snow showers over the mountains of
the Rocky Mountain Front will spread to central and southwest
Montana after midnight and continue through Sunday afternoon. Other
than some mountain obscurement conditions for the lower elevations
are expected to be VFR. Blank

&&

.PREV DISCUSSION...
/ISSUED 543 PM MDT Sat Apr 27 2013/

Quick update as of 520 pm MDT...Winds have increased across portions
of Hill and Judith Basin Counties in north central and central
Montana, respectively. Gusts in the area have increased into the
50-55 mph range, so have expanded the High Wind Warning to include
those two counties. Timing coincides with other warned areas.
Coulston

Tonight through Monday...Windy conditions will continue to be the
main forecast problem in the short term period. High winds are
currently being reported along the Rocky Mountain Front and over
the adjacent plains. This includes gusts to nearly 80 mph at Deep
Creek and up to 64 mph at the Cut Bank Airport. These strong winds
will continue into the evening hours but should diminish below high
wind criteria by midnight as pressure gradients weaken and the
core of very strong mid-level winds moves off to the east.
Isolated to scattered showers will be possible tonight through
Monday afternoon, especially over the mountains, but widespread
measurable precipitation is not expected during this time frame.
Breezy, but not strong, winds are expected for much of Sunday but
another wave will approach the area Sunday night and Monday. With
this next wind event it is possible that strong winds *may* be
more widespread over the plains than those of today, but details
are not completely clear at this time. Also, with the existing
High Wind Warning already in place, we have opted to not issue a
watch for this next event in order to avoid confusion. However, it
is likely that the evening or overnight shifts will either extend
the existing warnings in time through Monday or will issue a new
series of watch/warning products after this evening's event
expires. Finally, with a cooler airmass moving into the forecast
area behind the current cold front, temperatures will diminish 5
to 10 degrees each day with below seasonal average highs expected
by Monday. mpj

Monday Evening through Saturday...Latest model solutions for this
period continue to indicate the broad upper-level trof responsible
for the cooler temperatures and precipitation on Mon is forecast to
remain over MT thru midday Wed. As flow aloft switches to northwest
over central and southwest MT, bands of additional moisture dropping
southward behind the trof axis will generate areas of light snow Mon
night into early Tues morning.  As temps warm above freezing Tues
aftn, precip over the central plains/valleys will switch to
rain/snow mix or light rain, with light snow in the higher
elevations. Models also kept trend of much cooler temps as initial
cold air push with the front on Mon will be reinforced with
additional cool Canadian air on Tues, resulting high temps only
reaching the low/mid 40s on Tues.  The gusty winds expected on Mon
will also decrease steadily on Tues as the core of 130 mph jet
stream winds moves into ID/WY. Look for improving conditions
beginning Wed aftn as the last remnants of the trof exits into the
Dakotas and a strong high pressure ridge centered off the CA coast
builds through our region and into southwest Canada.  As winds aloft
switch to the west, marked warm air advection will push temps back
into the mid/upper 60s for Thurs through Sat. Expect mostly dry
conditions for the latter half of the week as well.  The GFS model
does try to bring a weak disturbance and some Pacific moisture thru
the east side of the ridge, producing scattered showers on Sat, but
given its better consistency the past few days, will stick with the
ECMWF model and its precipitation-free outlook for the time being.
