Area Forecast Discussion
National Weather Service Grand Forks ND
1058 PM CDT Thu Oct 28 2021

.UPDATE...
Issued at 1055 PM CDT Thu Oct 28 2021

The main concern for the overnight period will be potential and
timing of fog set up. Mist developed across the northern valley
for about two hours, however enough mixing with the NW winds
helped it erode with this last set of obs. Stratus ahead of a
Warroad to Sabin MN line will continue to move east leaving
clearing skies in its wake. As the surface ridge slides east,
winds will continue to decrease and enhance radiational cooling.
Models continue to target mainly NW MN (east of the valley) for
fog development by around 07Z. Have adjusted Wx grids for a bit
more fog coverage tonight, and will need to monitor for potential
headlines closer toward morning.

&&

.SHORT TERM...(This evening through Friday night)
Issued at 234 PM CDT Thu Oct 28 2021

Minimal impacts in the short term with high pressure ridge axis
traversing the area tonight. That said there is the possibility of
another night or morning of some fog impacts across portion of
NW MN as light winds and clear skies allow for radiational fog
development. Given the clouds today, recent rainfall and
saturated blyr persisting will add the fog mention from late
tonight through the morning commute Friday along the eastern edge
of the RR valley and into lakes country for portions of MN.

Tomorrow will see increasing mixing from west to east during the
day as southerly flow develops in response to developing low
pressure over the high plains. This mixing will bring highs to
near 60 in the west to low 50s east. Friday night will be the last
night above freezing with the southerly winds persisting and temps
holding in the upper 30s.

.LONG TERM...(Saturday through Thursday)
Issued at 234 PM CDT Thu Oct 28 2021

Principal chances for impactful weather really aren't presenting too
much as we head into a tranquil a cooler weather period to begin
November.

Sat offers best pcpn chances as a wave/sfc cold front moves from DVL
early in the day to WC MN by late aftn/eve. Winds will shift to the
W and NW and become breezy behind the feature, but little if any
pcpn is likely along with it.

Flow will be generally NW from this point on, bringing dry and
cooler weather to the forecast area. To wit : 850 mb temps dipping
below freezing more consistently yielding overnight lows well down
in the 20s with corresponding afternoon maxima limited to the 30s.

&&

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1055 PM CDT Thu Oct 28 2021

The back edge of the stratus has cleared TVF and should be through
BJI by midnight (05Z), definitely by the time the 06Z TAFs go into
effect. So think all sites will start off VFR (possible exception
of MVFR vsbys at TVF), with TVF/BJI seeing vsbys drop rapidly
somewhere in the 08Z to 10Z timeframe. Expect IFR cigs for early
morning flights as FG develops. Models area a bit slow
dissipating FG tomorrow morning, so late morning is possible and
will lean towards worse case as no strong confidence of a rapid
burnoff after sunrise.
