An intense arctic airmass is in place across ND and eastern MT. This would be very impressive in mid-winter, but even more so on Feb 17-19.  Coldest since early Feb 1996?

Here's the NWS forecast for Crosby, ND in the far NW corner of the state. Temps were in the minus 20s at midnight, so the daily max may end up around -20.  That is incredibly rare.

It dropped to -45F in Hettinger ND, under perfect radiational cooling conditions.  This is incredible, considering that it's relatively late in the season.  Probably around 50 degrees below normal (?).

-   Lots of Fire wx potential the next several days across the S Plains. Even a rare, (dry) thunderstorm potential around the KS/MO border region tomorrow (14th).

SPC going with another 'Extreme' risk area (like on March 4th). Amid very low sfc dew points to potentially < 0 F on Euro, strong/very strong winds, and warm temps.

Tomorrow could be a very serious severe weather event across KS and southward into OK, particularly in the evening. Incredible shear profiles will overlap with rapidly returning moisture along a 50-70 kt LLJ and weak CIN ahead of a rather potent dryline.
