Winter Weather Advisory in Effect Today

Bryan Dijkhuizen

An upper-level low is located over Lake Winnipeg in south-central Manitoba, with an accompanying clipper low piled underneath it. A cold front associated with this low pressure system is presently passing through the center of the forecast region, roughly along a line running from Carrington to Hettinger.

Strong northwesterly winds and patches of flurries are forecast to develop behind this front, which is represented on satellite imagery as a band of low stratus. The highest wind gusts will occur in western North Dakota during the early morning hours, while the heaviest winds will occur across the remainder of the region throughout the day today.

Even though the biggest pressure increases are expected to occur later in the day, steep low level lapse rates will enable winds up to 45 kts at the top of the boundary layer to periodically mix down to the surface throughout the day.

In terms of precipitation, some light snow will be possible along the front as it goes through, as well as behind the front throughout the day today when convective snow showers form under the influence of cyclonic flow aloft, according to the National Weather Service.

For the most part, convective-driven snow showers are unpredictable in terms of timing and location, therefore broad small chance to chance PoPs have been maintained over most of the CWA for the time being.

While it is not predicted to have significant blowing snow consequences due to the fact that the majority of the snow has crusted over, sources suggest that there is still some flowable snow throughout sections of the north central and northeast, in addition to any fresh snow that may fall.

Having stated that, no modifications to the present headlines are anticipated since they seem to adequately address the expected threats.

As indicated by radar and surface measurements, isolated snow showers have formed and are moving across the predicted region.

Therefore, at least an isolated snow shower has been added to all locations through this morning, and much of the predicted area through the afternoon.

Under these snow showers, transient vision decreases will occur with strong winds.

Speaking of winds, near advisory criterion winds will be possible throughout western ND this morning where there are no headlines, but the most of the clipper's energy is forecast to quickly migrate south and east, thus consequently no modifications to headlines are presently planned.
