10/21: Tranquil Week leading to More SNOW??

Evening Folks,

Not much to talk about this week Weather Wise except Dry, Seasonal, and Sunny Conditions we could experience through the rest of the Week and Weekend?  A small Clipper on Wednesday in the Dakota's but that's about it. 
<< Nothing is worthy of Mentioning, except MONDAY. 

From 58° to 36°, SOMETHING has got to give right?  Cold Temps & Precip means one thing; so lets talk about what I am seeing.






SUNDAY PM:  Models earlier this Morning showed warmer Temps nearing 60 but the Cool down increased with the late evening Model.  A large amount of moisture with the Front is poised to drop South into Northern WY by late Evening with Light to Moderate Snow in YNP/Absaroka's as a 1008mb Low forms in Southwest WY and Utah providing some Upslope potential for the Mountains. (IMAGE BELOW)

MONDAY MORNING: By Morning, the Cold Air is in Place as the Snow could start falling in Central WY while Moderate-Heavy Snow is possible in the Absaroka's and Bighorns.  We will keep that broad 1008mb Low to the Southwest as it slowly shifts East into Western CO. (IMAGE BELOW)


MONDAY EVENING:  The Low to the South in CO strengthens once more to a 1004mb Low.  Lots of Moisture with this Storm as compared to the last few Systems after our Big Storm early October.  Moderate to Heavy Snow is possible from Central WY down to the Laramies so cities of impact are Riverton/Lander/Casper/Cheyenne.  Another Thing to discuss about this Storm is the COLD Air behind it as Temperatures could drop in the Teens behind the Snow. Note how the storm 'wedges' with that Cold Air?... a Mature Storm.   (IMAGE BELOW)

TUESDAY MORNING:  Moisture still lingers via GFS in Central WY & I-80 as the Storm continues to slide South in the Denver area and East in Nebraska.  Some Flurries could stay through Mid-Day but the system is still too far away to know.


THOUGHTS:  This system is still very early in the Making to know for sure 'HOW MUCH' Snow can fall, the Timing and Placement of the Storm Track, but the other Model (EUROPEAN) is Similar to the GFS Run from this Evening but shows not as Intense with the Snow for Central WY. 

** IF the EURO Model this Evening Follows suit with the GFS in Intensity, we will have to closely monitor on the Consistency of both Models as the Storm nears next Week **
