Area Forecast Discussion National Weather Service Grand Forks ND 651 AM CST Sat Jan 25 2020

UPDATE. Issued at 647 AM CST Sat Jan 25 2020

Several locations across northwest zones shortly after initial forecast issuance went down to one- quarter mile visibility in fog. Added areas coverage back to the grids through 9 AM, although Cando has gone back up to one-half mile. Given continue SW winds around 10 mph don't think widespread dense fog will occur, so highlighting with the aforementioned coverage. Other than that no changes with 7 AM update.

SHORT TERM. (Today through Sunday) Issued at 238 AM CST Sat Jan 25 2020

The primary concern for impacts in the short term is chances/magnitude of a wintry mix associated with a boundary moving across the CWA from mid-afternoon through early Sunday morning. Fog threat is diminishing as southwest surface winds pick up.

High pressure is shifting east of the region and setting up southwest flow across eastern North Dakota. A warm frontal boundary moves across the northern tier today, and a band of precipitation is expected to form along and ahead of the boundary, entering the Devils Lake basin mid-afternoon. Soundings support freezing drizzle (very dry air aloft) however increased forcing could lift the parcel into the DGZ enough to allow some light snow to fall as ice is introduced into the cloud . so not completely confident on p-type this far out, but a mix of flurries and/or light drizzle is the most likely scenario. This will spread from 21Z through Devils Lake and into the RRV by 12Z Sunday. Although QPF values will be light, any freezing drizzle on untreated surfaces will likely result in travel-related impacts. Ensemble solutions weaken the line of activity as it moves into northwest Minnesota.

A weak surface low then slides into North Dakota on Sunday, with a chance for light snow or freezing drizzle behind the low as it moves into South Dakota. QPF associated with this system will be low with even less impacts expected than Saturday evenings event.

LONG TERM. (Sunday night through Friday) Issued at 238 AM CST Sat Jan 25 2020

Confidence is still higher that impactful weather will be minimal through much of the extended, though there is an increase in precip chances by next weekend that we'll need to keep an eye on for light wintry precip. We also can't rule out smaller scale patterns that support fog or brief freezing drizzle development, but these are always hard to anticipated there isn't a specific period in the extended I am confident in highlighting.

Split-flow pattern with trend towards rising heights keeps main storm tracks or any energy/deep moist advection minimal through the middle of next week. Non-measurable or very light measurable snow can't be ruled out through the middle of next week, however confidence isn't very high and trend with ensemble means/consensus have been for dry conditions for this forecast cycle for much of our CWA through Thursday. Ridging transitions into our region by the end of next week and eventually a stronger trough may begin to approach the region late over the weekend into southern Canada or even into our CWA, with increasing precip chances as WAA combines with increasing large scale ascent where this upper trough tracks.

There is high spread in GEFS plumes by late next week into the weekend regarding temps aloft and precip amounts likely as a result in members varying on track, timing, and evolution of this system. Mean surface temps are still shown to increase to near or above freezing ahead of this system (though there are clusters of ensemble members lower). We may see potential for mixed phase due to the potential magnitude of WAA immediately ahead of this wave, but this type of detail is even harder to anticipate/fine tune at this range. NBM 50-75th percentiles show potential for light snow accumulations in the Sat-Sat night of (and minimal ice accumulations). Still, at this range and the spread within ensembles lower confidence in impacts. Will need to monitor.

AVIATION. (For the 12Z TAFS through 12Z Sunday morning) Issued at 555 AM CST Sat Jan 25 2020

MVFR cigs prevail east of the Devils Lake basin but could dip into IFR range with passage of a frontal boundary late afternoon into the evening . with increasing chances of IFR cigs near the end of the 12Z TAFs. IFR this morning over DVL, improving during the afternoon hours. A mix of freezing drizzle and/or light snow possible with frontal passage in the 21Z to 09Z timeframe, moving west to east with activity weakening as it approaches TVF/BJI later tonight.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
