Area Forecast Discussion
National Weather Service Grand Forks ND
337 PM CDT Fri Mar 16 2018

.SHORT TERM...(This evening through Saturday)
Issued at 337 PM CDT Fri Mar 16 2018

High pressure has been persistent across the area and will continue
to be through Saturday. While a low pressure system passes to the
south, skies will remain on the clear to partly cloudy side in most
areas for the next 24 hours. However, there may be some low
clouds/fog developing late tonight in the west as southerly winds
help strengthen the low level inversion. Bufkit NAM data point
toward this potential as does the LAV and also some of the hi-
res models. The main threat for fog will be over eastern ND and
east across the Red River Valley on the MN side.

Highs tomorrow should be a bit warmer than today...with more 40s
expected on the Minnesota side.

.LONG TERM...(Saturday night through Friday)
Issued at 337 PM CDT Fri Mar 16 2018

Split flow upper pattern with ridge over the northern plains will
transition to a more unified flow regime by the middle to end of
next week. A couple of upper lows will be evident on Sun into Mon,
one digging through the southern plains with the other farther north
associated with a wave that will create pcpn over the forecast area.
Milder air out ahead will make pcpn type a concern Sun night into
early Mon with warmer air and erosion of ice aloft leading to
possible FZRA impacts Mon morning. Exact timing and placement
uncertain at this time but eventual cooling of column and inverted
trough will lead to an all snow situation for much of the afternoon
into Mon night.

Lingering light snow and flurries ending Tue with omega type upper
pattern developing mid to late week. Our area will be under the
upper ridge region likely boosting temps to near or above 40 south
of Highway 2. The next system will approach the region late next
week and again looks to feature a combination of rain/snow/mixed


.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1234 PM CDT Fri Mar 16 2018

It appears that there is an increased fog potential exists
tonight. Southerly winds will push warm air and moisture
northward...providing a good environment for fog formation. Have
made small incremental changes downward with visibilities
tonight at DVL, FAR, and GFK. Otherwise, quiet weather expected
during the day. Another chance for fog will exist tomorrow night.
