NEAR TERM /UNTIL 6 PM THIS EVENING/... For today, a large scale mid level trough will be digging southeast into the western Great Lakes and middle Mississippi Valley. This trough will be associated with an Arctic cold front which is poised to push into our region tonight. Large scale ascent will begin to bring light precipitation to our northwest zones this morning, mainly in the form of light snow. For this afternoon, precipitation will gradually increase in coverage across the northern zones as low to mid level frontogenesis starts to increase. Temperatures will start out warm enough that the precipitation will begin as a rain or a rain/snow mix when it arrives closer to the I-70 corridor. However, by late in the day, winds begin to turn toward the northwest with CAA increasing. This will change the pcpn to snow toward evening as another surge of moisture increases from the southwest. Will talk about that in the short term discussion. Otherwise, snow accumulations across the north will be low given day time insolation and some rain mixing in, about an inch or less. Highs today will vary quite a bit, ranging from the mid 30s far northwest to near 60 southeast. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... A very focused period of low to mid level frontogenesis is expected tonight, mainly for locations along and southeast of the I-71 corridor. As the mid level trough continues to dig east into the Great Lakes and Ohio Valley, aforementioned Arctic front will be pushed southeast. The increasing CAA from this front and moisture/WAA spreading northeast from a Gulf Coast Low will result in widespread pcpn for much of the southern/eastern forecast area. Rain will quickly mix with and then change to snow as temperatures drop. It still appears that the heaviest snow will fall across our southeast zones. Will be upgrading some of these counties from a Winter Storm Watch to a Winter Storm Warning where 3 to 5 inches of snow may fall. To the west of this Warning, will be issuing a Winter Weather Advisory for our lower criteria zones south of the I-70 corridor where 1 to 3 inches of snow may fall. For the Dayton and Columbus metro areas and points to the north, 1 to 2 inches of snow is expected. Will issue an SPS for locations in the lower criteria north of the Advisory/Warning area. With colder temperatures funneling southeast, conditions will become slick. Winds will become gusty overnight. It will be cold by morning with lows ranging from 15 to 20. Wind chill values will drop to near zero across the west and in the single digits in the east. The main shield of synoptic snow will be quickly exiting the region to the east Saturday morning. Continued CAA, steep low level lapse rates, and a fetch off Lake Michigan will bring a few snow showers. Temperatures will not warm much as 850 mb temperatures will be around -18 C. Thus, highs will only rise into the lower to mid 20s for the most part. It will be brisk with winds gusting close to 30 mph. This will result in wind chill values in the single digits and teens. By Saturday night, Arctic high pressure will traverse east across the Ohio and Tennessee Valleys. Skies will clear from the west. Then, WAA aloft will begin to spread mid and high level clouds east. Winds will settle down some in the evening, but pick back up from the south late. Lows will range from the mid to the upper teens.

I always thought that the Snow Hole is in DFW (AKA, the DFW Snow hole)

I have no idea what that is. Just know that most of the areas with no current advisories have gotten the shaft this winter.

This map beautifully illustrates the Snow Hole of 21-22. Lol. 

Found this and thought it was interesting. So now we know sleet is counted as snow accumulation, so knock about 3” off the total.

There's usually a really pesky Dry Slot every year that almost always situated over DFW, & on snow & rainfall maps in some years, that can be clearly seen
