Rain Changing to Snow

Temperatures are already 40° cooler than Saturday and moisture is streaming in to southern Colorado.  And so it begins...

As first mentioned eight days ago, an upper-level storm system is moving in to Colorado.  Cooler air is moving in from the north and we will see temperatures slowly falling off through the afternoon.  By 3pm, temperatures will be in the 30°s to lower 40°s. (Colorado Springs: 34° | Pueblo: 38°)

WEATHER WORD OF THE DAY: MOISTURE

Moisture is the big weather word of the day.  Short range computer models continue to be bullish with how much moisture will be available through Monday morning.  On average, data suggests 0.44" of precipitation will fall through 6am MT Monday.  Breaking it down further, a 27-computer model average suggests the following precipitation for locations through 6am Monday... Colorado Springs: 0.50" -- La Junta: 0.29" -- Lamar: 0.24" -- Monument Hill: 0.58" -- Pueblo: 0.49" -- Trinidad: 0.53".  If this were to fall as all snow, we would be talking about a BIG snow storm.  It won't be all snow, although some totals will be rather impressive Monday morning.

Initially, precipitation will fall as rain.  By late morning, we should begin to see rain changing over to snow.  First in the moutains and in El Paso County.  By late afternoon, the rain should begin to transition to snow in Fremont and Pueblo counties.  The transition will continue to move southeast before the entire area is all snow by this evening.

SOME MEASURING IN FEET

As mentioned above, some snow totals will be impressive.  My snow forecast still looks to be on track from yesterday.  I think the "winner" for biggest snow totals will be on/around the Wets.  Totals could reach 15" to 18" in the higher elevations.  Over the southern Sangre de Cristo mountains, there could be some areas measuring a foot of snow by Monday morning.

Here is a break down of my forecast for snow accumulation through Monday morning.

Cañon City: 3"-5"

Colorado Springs: 4"-6" of snow for central and southern part of city.  Northern Colorado Springs (Air Force Academy, Briargate, etc): 5"-7"

Northern El Paso County (Black Forest, Monument, Woodmoor, etc): 6"-9"

La Junta: 2"-3"

Lamar: 1"-3"

Pueblo: 2"-3"

Teller County: 8"-15"

Trinidad: 3"-5"
