.DISCUSSION...(This Evening Through Wednesday)
Issued at 146 PM MDT Wed Mar 27 2019
Northern stream trough has forced a cool front into the region
today, supporting breezy conds. Meanwhile, the western CONUS upper
trough is shifting east and will support a weak high centered
FGEN response tonight across NW SD, with better chances for more
widespread precip late Thurs into Friday.
A secondary backdoor front will settle into the region tonight
with ll flow turning ENE. This will support upslope flow with low
clouds and some high terrain fog developing late tonight. Weak
FGEN response further enhanced by a departing jet streak over ND
will support some light rain/snow across far NW SD. Dry BL will
counteract precip with only light amounts expected there, with
snow accums of less than an inch possible there. Upslope flow will
continue Thurs with low clouds and some high terrain fog expected
over western SD. Some breaks in the clouds will allow for warmer
conds over NE WY where deeper mixing is anticipated. The coolest
conds will likely be in eastern Black Hills and adjacent foothills
where easterly flow under cloudy skies will hold temps down. Some
light drizzle may also be possible at times, esp if cloud bases
lower to 1 kft or less. Rockies upper trough will shift SE with
the bulk of GOMEX moisture shifting away from the FA. This will
shunt higher QPF and associated best precip chances south, with
only the SW half likely seeing any precip. Precip is expected to
develop late Thurs night with perhaps some Thur evening convective
showers ahead of the main wave as indicated in some hires models
INVOF the BH. As stated above, the best overlap of
forcing/moisture is expected to situate south of the FA, as well
as the best chance for higher QPF and snow accums. Still expecting
some light snow accums (with some ZR possible Fri morning in the
far western SD upslope areas given drying mid levels). However,
with a portion of the precip falling during the day Friday, snow
accums will be limited to mostly grassy sfc’s during the day
Friday as snowfall rates will be limited (except perhaps the far
SW FA), with any morning freezing rain/drizzle being minimal. At
this time 1-3 inches of snow still looks likely in mainly the far
SW FA, perhaps local amounts to 4 inches from southern Campbell
County to Fall River County with QPF amounts up to one half inch
in the far SW.
Unsettled NW flow is on track this weekend into early next week
with temps at or around seasonal norms and passing drier impulses
likely supporting some sct showery precip at times. Another
stronger low may cross the Northern Plains toward Tue-Wed next
week, with very low confidence in the track of this system at this
time.

.AVIATION...(For the 06Z TAFS Through 06Z Thursday Night)
Issued At 1046 PM MDT Wed Mar 27 2019
VFR conditions expected through 09z. After 09z, moist upslope
flow will combine with weak disturbance to produce MVFR/IFR CIGS
Tuesday, first starting over far northwest SD into the Black Hills
and then spreading onto the plains during the day. Some fog
expected over the highest elevations. Some mixed precipitation may
fall near the MT/ND border tonight with some light rain/snow
possible during the day Tuesday. A more organized disturbance will
bring better chances for mixed precipitation Tuesday night.
