Area Forecast Discussion National Weather Service Grand Forks ND 654 AM CST Tue Dec 10 2019
UPDATE. Issued at 652 AM CST Tue Dec 10 2019
Made only a few minor tweaks to temps and clouds for the ones exiting the area. A few spots are still reporting haze or flurries (actually ice crystals lofted by overnight winds). That trend has been decreasing in the last few hours as winds decrease.
SHORT TERM. (Today through Wednesday) Issued at 406 AM CST Tue Dec 10 2019
Wind chills and how to handle headlines are the main concern for the period.
Secondary cold front continues to move across our south and east, with some cloud cover and flurries with it. Continued with mention of snow for a bit longer, but think we should be clear and dry by sunrise. The center of the Arctic high is well to our west over eastern MT, and is expected to drop down through SD later today. That will keep at least a little bit of a pressure gradient for much of the day with west to southwest winds staying in the 5 to 15 mph range. Our western counties should see enough weak warm air advection to get a bit closer to the zero mark for actual temperatures and above wind chill advisory criteria this afternoon. Most of our eastern counties will be a bit colder and other than an hour or two, will stay in wind chill criteria for much of the afternoon. Another reinforcing shortwave will dig down late this afternoon and tonight with another surface high dropping into the Northern Plains. Winds will be a bit lighter tonight, but clear skies will allow temps to approach the -20 mark and wind chills will be enough to reach criteria across the whole CWA. Extended the wind chill advisory across most of the MN counties (except Wilken and Clay), and have the western portions of the CWA coming back in for another wind chill advisory starting at 03Z tonight. The cold temps and wind chills will hang on through most of Wednesday morning.
Later in the day on Wednesday, a shortwave moving into eastern MT will push some increasing clouds into our CWA. Think at this point that precip from this shortwave will stay mostly to our west before 00Z Thursday, so kept dry for now.
LONG TERM. (Wednesday night through Monday) Issued at 406 AM CST Tue Dec 10 2019
Main story for the long term period will be chances for snow and an additional chance for cold conditions this weekend.
Wednesday night- Thursday: A clipper is expected to move through from the northwest Wednesday night across the Dakotas and Minnesota. There are some similarities of this clipper to Sunday night's clipper which resulted presented a challenge in forecasting location highest amounts. This was mainly due to uncertainties regarding a strong mid level fgen band, but as is typical of any mesoscale forcing light frontogenesis. The upcoming clipper is suggested to develop northwest-southeast 900-700 mb frontogenetical forcing on the head of low level warm air advection driven by synoptic forcing from the parent shortwave trough. Hi res guidance is just now starting to view the beginnings of this and indeed some depict developing northwest/southeast snow band/s in central North Dakota Wednesday evening. Luckily the orientation of fgen compared to the track of the clipper suggests mesoscale forcing shouldn't linger over a particular area very long limiting the potential for locally large accumulations.
There are some differences between this and Sunday night's clipper. This clipper looks to be weaker and more compact, which should help limit the strength and depth of WAA/frontogenesis. Though its compactness may suggest its track can shift easily, thus lowering confidence even more on snowfall placement. It will also have to overcome dry air ahead of the system which may at least help delay the onset of snow. Once the column does saturate, snow production shouldn't be hard to come by given the majority of forcing within a deep, saturated DGZ. As is typical of clippers, it should be rather progressive across the area with snow exiting the CWA to the east by Thursday midday. Milder temps into the teens above zero expected Thursday. Currently the forecast reflects a general 1-2 inches across the region (owing to lack of better synoptic forcing and moisture), however given the potential for mesoscale forcing locally higher amounts are possible with no clear indication of where.
Friday - Tuesday: Hot on the heels of the mid week clipper will be another clipper to move through from the northwest Friday. Details remain fuzzy on this system, although it looks to be synoptically a bit stronger than the previous. Snow amounts and placement are unclear at this time. Some guidance suggests enough warmer air advects into the region while scouring ice nuclei to bring the whispers of freezing drizzle back into the forecast. As per usual, confidence is very low on this potential this far out. Strong CAA behind Friday's clipper does point to another shot of cold air this weekend with low temperatures dipping back below zero.
Flow aloft starts to become more zonal early next week with signs of ridging starting to show up in ensemble guidance. This would promote milder temperatures for this time of year. I cannot comment on precip chances given spread in guidance, but typically milder temps means potential for more moisture availability.
AVIATION. (For the 12Z TAFS through 12Z Wednesday morning) Issued at 533 AM CST Tue Dec 10 2019
A few airports reporting flurries or haze with 3-5SM visibility, from ice crystals that were lofted by the recent gusty winds and have yet to settle out. This will continue for another hour or two on and off before all sites become VFR. Winds will be on the northerly or southerly side of westerly for most of the period in the 8 to 12 kt range.
