Warm near summer-like day quickly transitions back to winter.
I hope you were able to take advantage of the beautiful weather Saturday. High temperatures topped out in the 70°s and 80°s. Officially, Colorado Springs hit 71° and Pueblo hit 80°. Interesting to note that today marks the third time this month Pueblo has hit 80°. This surpasses April 2013 which only saw 80°+ two times. April 2012 reached the 80° mark five times.
Temperatures tonight should remain relatively mild. Under mostly cloudy skies, lows will be in the 40°s by 6am Sunday morning.
REVERTING TO WINTER
As first mentioned last weekend, temperatures are projected to plunge 40° to 50° by Sunday afternoon. By 3pm, temperatures will likely range from the 30°s and 40°s across southern Colorado. (Colorado Springs: 35° | Pueblo: 38°)
Along with the colder air, moisture will begin to move in to the area. In fact, short to medium range computer models are aggressive with the amount of moisture available to work with. A 27-computer model average suggests the following moisture (in liquid measurement) through 6am Monday. Colorado Springs: 0.47" -- La Junta: 0.32" -- Lamar: 0.30" -- Monument Hill: 0.66" -- Pueblo: 0.43" -- Trinidad: 0.53"
The temperature profile of the atmosphere will initially be supportive of rain, which is probably a good thing or else we could be talking about BIG snow totals east of the mountains. The rain should begin to change over to snow starting during the afternoon. By late evening most of southern Colorado should be over to snow. (See image to right.)
The million dollar question is "How much snow?". Here is a break down of what I think we could see in accumulated snow through 6am Monday morning...
Colorado Springs: 4"-6" inches for central and southern part of city. Northern Colorado Springs (Air Force Academy, Briargate) could see 5"-7".
Northern El Paso County: 6"-9"
La Junta: 2"-3" -- Lamar: 2"-3"
Teller County: 8"-15"
Wet Mountains: 10"-18"
Southern Sangre de Cristo Mountains: 8"-16"
