Punxsutawney Phil's prediction of six more weeks of winter looks like it could be true. A major winter storm is sweeping across Colorado. Over 270 flights that were to be flying in or out of the Denver International Airport have been cancelled. Snow began falling Thursday night after 7:00pm. As of Friday morning, Pinecliff, just west of Denver, was hit with 18 inches of snow.

According to the Weather Channel, Colorado is in a blizzard warning, and could get over a foot of snow in some areas. Besides flight cancellations, schools and some highways are closed. Interstate 70 is closed from Limon to a little bit east of Denver, almost 70 miles. Numerous accidents have also caused the closure of a ramp on I-25, reports the Weather Channel.

Mike Seidel, Weather Channel Meteorologist reporting from Englewood, Colorado, has said that winds are at 25 mph, with gusts reaching 30-32 mph.

Heavy snow fall is expected to fizzle late Friday night. The weekend is expected to weaken the storm, with a possibility of it rolling into the Washington D.C. area. The Washington Post warns of a chance of a snow for D.C. Saturday night. Winter storm watches for Friday night through Saturday have extended to Nebraska, and northern Kansas.

The National Weather Service in Denver has cautioned that, Travel conditions across northeast Colorado are expected to become very difficult, if not impossible, later tonight.

ABC predicts that the storm could make the list of top 10 heaviest snowstorms to hit Denver. The 10th biggest snowfall in Denver History was in 1912 with 22.1 inches.

While crowds seemed displeased with Punxsutawney Phil's prediction of six more weeks of snow, it seems that once again the Pennsylvania groundhog has hit the mole on the head.
