An arctic airmass will remain over eastern Utah and western Colorado through today (Halloween), resulting in abnormally cold temperatures. Daytime highs today will be 15 to 25 degrees below normal across the board under mostly sunny skies and dry northwest flow aloft. Be sure to bundle up during prime trick-or-treating hours this evening as temperatures drop into the mid to upper 20s and lower 30s across the southern and central valleys and into the upper teens further north between 6 and 9 PM. Another round of record cold low temperatures will occur tonight/Friday morning.

Temperatures will warm up Friday onwards.
