KEY MESSAGES

- Significantly colder temperatures continue through the remainder of the weekend with highs in the 20s and 30s, and lows in the single digits to teens above zero. A quick warm- up to near or above average temperatures is favored for the next workweek.

Any lingering light snow and flurries should continue to taper off this afternoon. In addition, skies should continue to gradually clear off through the early evening, becoming mostly clear overnight as surface high pressure dips into the state. This will allow for some of the coldest temperatures so far this season with lows throughout the state expected to drop down to around 5 to 15 degrees above zero, though the Red River Valley will likely remain a few degrees warmer. These colder temperatures will persist through the remainder of the weekend with highs Sunday in the mid 20s to mid 30s, and then lows Sunday night dropping mostly into the teens above zero.

Meanwhile, a west CONUS ridge will amplify significantly through the remainder of the weekend. An initially transitory upper low will pass from western into central Canada, while flattening and widening the ridge thus resulting in strong WAA Monday. Simultaneously, surface high pressure will sink southeastward through the Central and into the Southern Plains states, which will result in breezy southerly flow at the surface. Combined, these will produce quite a contrast in temperatures on Monday with the eastern half of the state forecast to remain in the mid 30s, while the western half will range from the mid 40s to mid 50s.

Beyond Monday, northwest flow aloft is expected to persist through most of the workweek before things become more uncertain next weekend. While this favors mostly dry conditions as produced by the NBM, embedded shortwave energy in northwestern flow aloft occasionally produces light precipitation that is often difficult to forecast well in advance. Overall, this pattern will create a trend that is quite frequent during the North Dakota winter season to where the northeastern corner of the state will be much cooler than the southwestern corner. In this case, that translates to above average highs in the low and mid 40s northeast to the 50s southwest, and may even approach 60 in the far southwest towards the end of the workweek. That said, ensembles suggest high uncertainty in regard to highs Friday through next weekend so take that with a grain of salt. Lows Monday night through next week are mostly forecast to range from the mid 20s (near to slightly above average) to mid 30s (above average).

MVFR/IFR ceilings are present across most of the state, though parts of western ND are beginning to clear off. These lower ceilings will gradually improve throughout the afternoon and into the overnight hours as clearing expands throughout much of the area. Other than isolated flurries, most snow showers are near the ND/SD border and will continue to taper off over the next couple to few hours. Once any snow ends and ceilings improve, VFR ceilings and visibility will be on tap for the remainder of the period.
