beavis1729 Posted Monday at 08:31 PM Share Posted Monday at 08:31 PM 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. Washington's Birthday Sunny and cold, with a steady temperature around -20. Wind chill values as low as -40. North wind 3 to 8 mph. Tonight Partly cloudy, with a low around -45. North wind around 5 mph becoming calm in the evening. Tuesday Sunny and cold, with a high near -14. Wind chill values as low as -45. Calm wind becoming north around 5 mph. Tuesday Night Mostly clear, with a low around -43. Wind chill values as low as -60. Light and variable wind becoming northwest around 5 mph in the evening. Wednesday Sunny and cold, with a high near -5. Southwest wind 5 to 7 mph becoming southeast in the afternoon. Wednesday Night Clear, with a low around -26. South wind 6 to 10 mph. 1 Link to comment Share on other sites More sharing options...
