Everything still looks on track for a "doozy" of a storm just in time for Mother's Day.
My current thinking is that we will start to see precipitation moving through the south-central mountains of Colorado early Sunday morning.
By late morning, we should start to see precipitation falling across western Fremont and Teller counties. This will likely start out as rain and then change over to snow.
Around noon precipitation could start to fall in northern/northwestern El Paso County, including Colorado Springs. Agan, this will likely start as rain, then changing to a winter mix, before changing over to all snow by late afternoon.
For places like Pueblo and La Junta, rain will be possible during the afternoon. I can't rule out the chance for a rumble of thunder. Most of the precipitation should fall as rain. There is a period overnight where temperatures may drop low enough to allow for change over to a little snow in Pueblo. At this time I don't see much in the way of accumulating snow for Pueblo. Think the city could be lucky to get 0.5" to 1" through Monday morning.
One of the problems with this snow is that it will be wet and heavy. Trees have already started to bud and leaves on branches will help collect snow. This could cause tree limbs to break where the snow is heaviest. Breaking tree limbs could fall on power lines, which in turn could cause power outages in some places. We'll have to wait and see how this works out.
HOW MUCH SNOW?
Computer models are still widely varied as to how much snow they are suggesting. It makes forecasters' jobs easier when they are all pointing in the same direction. So far, they haven't done that.
As of 6:00pm, here is how much I think areas could see through late Monday morning...
- Colorado Springs: 3"-5" for central and southern Colorado Springs
- Northern/Northwestern El Paso County: 7"-10"
- Teller County: 8"-14"
- Wet Mountains: 3"-5" in lower elevations. 5"-10" in higher elevations. Above 11,000 feet there could be as much as 8"-13"
We will have a wide range of temperatures Sunday. Temperatures should top out in the 40°s to 70°s east of I-25. A cold front will be moving south through the area which will cause the inital jump in temperatures before it passes, but once it does pass, temperatures will fall through the afternoon. (Colorado Springs: 46° | Pueblo: 60°)
WINTER STORM WARNING & ADVISORIES
The National Weather Service has issued winter storm warnings and advisories for much of the state. (see image at right)
Winter Storm Warning is indicated by areas shaded in pink. Winter Weather Advisories are shaded in light purple.
The Winter Storm Warning for the KOAA viewing area is in effect from 9am Sunday through 9am Monday.
MAY SNOW RECORDS
Interesting weather tidbit. The record daily snowfall for Colorado Springs May 11 is 1.9" set in 1966. The record daily snowfall for Colorado Springs May 12 is 3.0" set in 1912. Think there is a chance we could make a run on one of these records.
*Keep in mind the official snow total is measured at the Colorado Springs airport on the southeast side of town.
