National Weather Service Grand Forks ND
104 PM CDT Thu May 18 2017

.UPDATE...
Issued at 103 PM CDT Thu May 18 2017

no changes to going fcst.  high temp trends look good.

&&

.SHORT TERM...(Today and tonight)
Issued at 300 AM CDT Thu May 18 2017

As surface low over far se Mn shifts east, wrap around -ra should
be ending across the far se. Will monitor radar trends to see if
pops will be warranted. By late morning winds through the mixed
layer drop off to around 15kts so diminishing winds in order.
Drier air moving in and with high convective temperatures once
clearing takes over not anticipating any sc/cu development. Even
with eventual solar temperatures will be well below average with
highs in the 50s to around 60.

Frost main impact tonight however unsure at this point how
widespread so will let the day shift fine tune the favored area
for frost. Most areas will see lows dropping off into the 30s.

.LONG TERM...(Friday through Wednesday)
Issued at 300 AM CDT Thu May 18 2017

Next upper wave will propagate into the central plains later
Friday. Appears to be a lead impulse ahead of main wave lifting
into SD so will maintain pops for later in the day. Column warms
slightly but increasing clouds will likely keep temperatures
closer to what we have had.

With upper low taking a more nw track through the FA rain chances
will increase from south to north Friday night with best rain
potential Saturday as low lifts through. With clouds and rain
high temperatures only in the 40s and 50s. Wrap around rain to
continue Saturday night over all but the far west.

For Sunday...a slow moving surface system continues to push
northeast crossing Lake Superior into southern Ontario...with some
wrap around moisture affecting the eastern portion of the forecast
area with light precipitation.

For Monday through the end of the period...the upper trof shifts
east and the upper ridge begins to shift across the Dakotas and
Minnesota. Temperatures are expected to start off cooler under the
upper trof...but rebound by the end of the period as the ridge
shifts east. Otherwise...little to no precipitation is expected at
this time.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 103 PM CDT Thu May 18 2017

VFR thru the pd. Skies clear to a few cirrus with northeast winds
diminishing as high moves into the area tonight.
