Area Forecast Discussion
National Weather Service Grand Forks ND
334 AM CDT Fri Apr 28 2017

.SHORT TERM...(Today and tonight)
Issued at 329 AM CDT Fri Apr 28 2017

Upper level low was over NW Ontario early this morning. One last
piece of energy rotating around it last evening is now moving in
its south side. Some light snow with it at Kenora and Baudette.
This wave will move east this morning as well as the upper low.
Clouds over NW MN and parts of the RRV will gradually clear out
from the west today...though it will take most of the day to do it
for Lake of the Woods. High pressure will continue to build into
central ND today and move over the Red River valley tonight. With
the sun, and a slowly moderating airmass areas in the Red River
valley and west will see low to mid 50s while the eastern fcst
area will see low-mid 40s. Tonight will see lows a bit below
freezing with light winds and clear skies.

.LONG TERM...(Saturday through Thursday)
Issued at 329 AM CDT Fri Apr 28 2017

Sunshine and a bit milder on Saturday as our temperatures recover
from the last several day cold wave. Sunday will be mild once more
with highs mid 50s to low 60s. Clouds will increase into west
central Minnesota Sunday afternoon as a large upper low and
accompanied sfc low move northeast from the central Plains toward
Minnesota and Wisconsin. Precip on the western side of the upper
low will impact west central MN starting in the 06z-12z period
Monday. Surface, 925 mb and 850 mb temps just cold enough for a
mix of rain turning to snow.

The main story for Monday into Monday night will be the 500mb low
that is forecast to lift from Iowa into the central Great Lakes.
This is expected to bring a decent chance of pcpn, mainly to west
central Minnesota. Bumped up pcpn chances in this area a little
more from what guidance came in with and lowered high temperatures
a tad on Monday. At this point, it appears it will be a mix of
rain and snow, with snowfall accumulations of an inch or two. The
biggest challenge for accumulating snow in the southeast FA will
be that most of it falls during the day hours.

After this system tracks to the east, the question shifts mainly
back to temperatures. 500mb ridging shifts into the Rockies and
could push a little further east, but flatten out a little. 850mb
temps begin to rise, with guidance indicating a return to around or
a little above 60 by Thursday/Friday. Could be a few small chances
for light pcpn, but no strong signal at this point.


.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1146 PM CDT Thu Apr 27 2017

A mostly cloudy sky was over the MN side and a mostly clear sky
was over the ND side. Mostly VFR conditions were over the forecast
area. MVFR cigs were mostly over the southeast zones. Expect
mostly MVFR conditions over the southeast zones for the rest of
the night. The rest of the forecast area should have VFR
conditions for tonight and Fri. Cloud over the MN side should
slowly shift east Fri.
