Make no mistake changes in our local weather are coming next week. A massive upper level ridge of high pressure and its associated blocking will help drive a potent arctic airmass southward deep into the U.S. next week. The Montana Rockies will see temperatures some 60 degrees below normal next week with some cities in Montana and Alberta dropping well below zero,
Surface pressures across Montana may climb up into the 1060 millibar range...a true testament of the strength and cold of this impending arctic invasion.
Southeastern New Mexico will see our afternoon high temperatures climb up into the 75-80 degree range Sunday and Monday ahead of the southward moving arctic cold front. These readings will be some 20-30 degrees above normal.
The jury is still out on just how cold we will get by the middle of next week and beyond. Historically the models tend to be too warm with these frigid outbreaks of arctic air, and I think this may be the case with this one as well. Current forecasts indicate that the arctic cold front will arrive in southeastern New Mexico Monday night or Tuesday morning.
So our high temperatures Wednesday into Friday may end up being some 15 - 25 degrees below normal or possibly colder. For now Thursday looks like the coldest day next week with widespread 30's for highs. Lows Friday morning may be in the low 20's.
Much can and will likely change concerning this event over the next few days so stay tuned.
