Area Forecast Discussion
National Weather Service Grand Forks ND
659 AM CDT WED MAY 25 2016

Issued at 659 AM CDT Wed May 25 2016

Precip breaking up as it moves north. Updated the pops for current
radar trends. Otherwise no other changes at this update.


.SHORT TERM...(Today through Friday night)
Issued at 344 AM CDT Wed May 25 2016

Water vapor loop indicated a trough from eastern WY into eastern CO
and was moving to the northeast about 40 knots. Some
drying/darkening was noted over eastern WY/eastern CO. Short wave
ridging east of trough was returning moisture northward. Band of
precipitable water over an inch and a quarter forecast to rotate
northward through the forecast area through 00z Thu.

Coupled upper level jet was over the area with jet over southern
Canada and a southwesterly jet nosing into southeast ND by 18z Wed.
Coupled area shifts into Ontario this evening with respectable upper
level divergence. Precip basically falls under the 700 hpa theta-e
ridge. Water column then dries out tonight and Thu. Precipitable
water increases again for Fri/Fri night as upper low off the
southern CA coast moves out into the plains of NE. Concurrently an
upper trough over western MT will move into northern ND/southern MAN
Fri/Fri night.

.LONG TERM...(Saturday through Tuesday)
Issued at 344 AM CDT Wed May 25 2016

Saturday through Tuesday...The wet pattern will continue with
several troughs moving through the Northern Plains. The first will
lift from the Central Plains into Minnesota on Saturday, and another
large trough coming in from the Rockies on Tuesday. In between, west
to southwesterly flow will prevail over the Northern Plains and any
of the weak embedded shortwaves could bring some precip. Blended
solution gives fairly high POPs throughout the period, with some
slight decrease down to 15ish percent Sunday night and Monday at the
driest. Given the pattern see little reason to change that wet
solution at this point. Temperatures will continue to be mostly
above seasonal averages.


.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 659 AM CDT Wed May 25 2016

IFR cigs have moved westward into the far eastern zones. Otherwise
the rest of the area was VFR. Expect mostly VFR conditions for today
except near storms.
