© NWS Boulder18 to 36 inches of snow has fallen in the foothills with this spring storm. An additional 6" to 12" is expected by morning
The storm has created headaches for travelers on highways, caused thousands of power outages and forced schools and businesses to close.
The highest reported snow total was 38.5 inches near Ward, Colo., the National Weather Service said. Many other locations picked up between two and three feet.
More snow is forecast Friday before it tapering off Saturday.

Cities such as New York, Boston and Portland, Maine, soared into the low- to mid-90s and were hotter than the likes of Phoenix, Los Angeles and Miami.
At 3 p.m., Boston stood out as the hottest city in the nation — something that hardly ever happens. The mercury had risen to a scorching 95 degrees.
Connecticut, according to WeatherBell Analytics meteorologist Ryan Maue, was the warmest state in the nation.
Record highs were falling like flies in New England. Nearly every major city along Interstate 95 set a record for the date, and a few spots were closing in on monthly records.
Some of the records established Thursday afternoon:
- Newark hit 94, breaking a record of 90 from 1986
- LaGuardia Airport in New York hit 96, shattering the record of 86 from 1989 and just one from its monthly record high of 97.
- Central Park in New York hit 91, breaking the record of 90 from 1936
- Providence, R.I., hit 93, breaking the record of 92 from 1936
- Hartford, Conn., hit 96, breaking the record of 90 from 1936
- Boston (Logan Airport) hit 95, breaking the record of 91 from 1936 and tying for the third-hottest May reading on record
- Blue Hill Observatory just outside Boston hit 95, its hottest May day recorded back to 1885.
- Burlington, Vt., hit 93 degrees, breaking the record of 89 from 1989 and tying for the warmest May day on record.
- Concord, N.H., hit 94, shattering the record of 86 from 1906 and 1889.
- Portland hit 91, shattering the record of 82 from 1949

A strong thunderstorm band swept through the Denver area between 9 and 10 p.m., bringing heavy rain, up to an inch per hour in some areas, along with hail in some spots, according to the National Weather Service.
Pea-size hail fell in the Dacono area along the I-25 corridor north of Denver at about 8:50 p.m. to a depth of 4 inches, according to the weather service.
Snow levels along the Wyoming state line dropped down to 7,500 feet in elevation about 8 p.m. Wednesday.
Lightning flashed across the night sky Wednesday as rain and hail swept through the area.

Utility vehicles were scrambling up Rattlesnake Drive, where dozens of branches were down across power and communications wires.
For fallen trees and limbs that are not blocking a street or threatening power lines, Missoula residents can call the City Park Operations Office at 552-6253. Those with fallen tree limbs blocking travel can call the City Forester at 552-6270 to get a crew out as soon as possible.
National Weather Service volunteer observers reported 5 inches of snow in many places around Missoula.

Grouse Mountain saw a total of 25 centimetres of fresh snow skiers. Cypress Mountain and Mount Seymour both remain closed for the season.
Meanwhile, snowfall is forecasted to continue in the Interior, and Environment Canada has sent out a warning to motorists to expect winter conditions between Hope and Kamloops, as well as along the Okanagan Connector from Merritt to Kelowna. Conditions are expected to get worse later in the day.
An unusually strong low-pressure system for this time of year is currently moving through the region. This movement brings colder temperatures into the mid-levels of the atmosphere. As the temperatures aloft fall, so does the snow level.
This morning, the snow level had fallen to around 3,000 feet. While it's not unusual to see May snow in the Cascades, it is somewhat rare to see accumulating snow this low this late in the year. If you're traveling over the mountain passes today, plan on encountering some slushy snowfall on the range of 1-4 inches. Above 4,500 feet, the totals will be closer to 6-12 inches.

More than 30 inches of snow enveloped Mount Washington Observatory this weekend — just days before parts of Massachusetts are expected to have temperatures in the 90s.
The snow started Saturday night at the New Hampshire observatory and continued through Monday, covering the mountain with about 33 inches before stopping, according to a Facebook post from the observatory.
A May snowfall is not unusual at the observatory, said Chris Kimble, a National Weather Service meteorologist. About 12 inches of snow typically falls in May at the observatory, which has an altitude of 6,300 feet.
But this weekend's storm broke a couple weather records, including the largest snowfall for a single day in May.
"In 1967, 22.2 inches fell, and this weekend we got 22.9 and counting," Kimble said.
The record for the largest single-storm snow in May was also broken, he said. From May 21 to 24, 1997, the observatory was hit with 30.6 inches of snow. This weekend, 33.3 inches fell.
So far, over 45 inches of snow have fallen at the observatory this month.
