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

.UPDATE...
Issued at 947 AM CDT Wed May 25 2016

Seeing quite a bit of shower and tstm activity across the FA this
morning, but the most extends along a line from KJMS to KAXN.
Seeing some cyclonic curl in this line, so its forward speed is
not all that quick. Ahead of this line some other clusters of
pcpn have developed too. One cluster is northwest of KBJI and
another is around KDVL. Models show the main line from KJMS to
KAXN lifting northward through the FA today, giving a wide 0.25 to
0.50 inch rainfall to most areas. After this line moves through,
will have to see how much clearing occurs. Will need to have some
clearing and heating to get additional tstm development this
afternoon. Best bet for any clearing at this point looks to be
across the southern FA. SPC has removed the slight risk area but a
marginal risk still exists across the southern third of the FA.
This matches well with the area that stands the best chance of
seeing sun later, but lots of ifs yet. Will continue to monitor
through the day.

.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.
