700 PM CDT Fri Sep 14 2018

.UPDATE...
Issued at 655 PM CDT Fri Sep 14 2018

Tweaked pops, temps and dewpoints to match current conditions.
Essentially no other changes at this update.

&&

.SHORT TERM...(This evening through Saturday)
Issued at 336 PM CDT Fri Sep 14 2018

Cloud cover pattern has remained pretty consistent thru the
afternoon. In the past hour visbile satellite pics have shown
increased high based CU within the general lower cloud region
along the ND/SD border into west central MN thru Wheaton to
Alexandria. Starting to see a few echo returns along this line.
Also have started to see the lower clouds returning northward
approaching Bemidji and Fargo. So the intial process of 850 mb
warm front returning northward is occurring. Short range models
are not too agressive in developing activity thru early evening
but do have some shower/tstorm activity...but holds off til mid to
late evening and esp later tonight more toward north central and
northeastern MN. So will start out with lower pops then increase
them thru the evening into west central MN toward Bemidji.

Saturday will see the 850 mb warm front lifting north but the
surface warm front seems to linger quite a bit south until the
aftn when it does more into WC MN and far SE ND where highs today
in the low-mid 80s. 850 mb instability will be present over the
area near the 850 mb warm front, and it seems mid to late
afternoon will see best chances for scattered storms to form in
parts of NE ND into far northern MN.

.LONG TERM...(Saturday night through Friday)
Issued at 336 PM CDT Fri Sep 14 2018

Saturday night through Monday... The weather in this period is
driven by a short wave trough and a surface low pressure system that
moves across North Dakota and Minnesota. Saturday night into Sunday
morning a warm front will move across eastern North Dakota and
northwest Minnesota bringing chances for rain showers and
thunderstorms. The cold front will pass Sunday afternoon into Sunday
night from west to east bringing cooler temperatures. Temperatures
will be warm on Saturday night and Sunday then much cooler Monday
after the passage of the cold front with temperatures near to just
below normal. Winds are also expected to be elevated Sunday as the
low pressure moves across the region with wind gusts over 30 mph
possible.

Tuesday through Friday... High pressure and an upper level ridge
moves in Tuesday leading to quiet and cool weather. The next chance
of rain comes on Wednesday as an upper level trough moves towards
the Northern Plains. There are some differences in the global models
in this period as the ECMWF is more progressive and has most of the
rain falling on Wednesday while the GFS and CMC have the rain later
on Thursday. So confidence in the occurance of rain is high the
timing is still somewhat uncertain. Surface high pressure to settle
in again after this system passes late next week. Slightly below
normal high temperatures expected for this period next work week.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 655 PM CDT Fri Sep 14 2018

north to about the southern half of the forecast area by Sat morning
and into the northern zones by Sat late afternoon.
