Our First Blast Of Winter Wx Today Into Monday.

Blog updated at 10:15 AM MST.

Today Into Tonight.

Its fairly easy to see that the arctic cold front had entered northeastern New Mexico as of 5 AM MST this morning. The front will move steadily southward throughout the day today, and by tonight all of southeastern New Mexico and much of west Texas will be overrun with a much colder airmass.

There is going to be a battle today between the arctic airmass behind the approaching arctic cold front that is currently moving southward, and the warm dry downslopping southwesterly winds ahead of the cold front.

 This mornings 12Z/5 AM MST NCEP RAP model (temp forecast maps above) is latching onto this. So we may see our high temps climb up into the upper 50's to the low 60's across Chaves, and Eddy Counties this afternoon before the cold front arrives. But if the arctic cold front picks up speed, and surges south faster than forecast, then our highs will crater faster and won't be as warm. 

Upper Level Storm Headed South Today.

Valid At 5 PM MST This Afternoon, Sunday December 9, 2012.

Our approaching winter storm was located over northern Colorado and Wyoming at sunrise this morning. It is forecast to sink southward today, and by sunset be located over northern New Mexico. Just how far south it sinks into the state will help determine just how much snow falls across eastern and southeastern New Mexico and nearby areas. 

Snowfall Potential.

Temps Monday Into Tuesday Morning.

Although this inbound winter storm is not expected to produce heavy snow across the lower elevations of southeastern New Mexico, we should at least get a dusting, with some places perhaps getting as much as an inch or two of the white stuff. The higher elevations of the mountains stand a better chance of seeing some decent accumulations. 

A much colder airmass will usher in very cold wind chill vales tonight into tomorrow morning, which will drop down to the single digits and teens across most of the local area. Our overnight lows are forecast to dip down into the teens Monday morning, with similar readings Tuesday morning. Most of us may not get out of the 30's and 40's for highs on Monday. It will most definitely feel like winter has arrived starting tonight.
