Snow will continue over much of the area comprising Denver and the surrounding region through Wednesday evening, according to the National Weather Service (NWS).
Snowfall is expected to be heaviest in a band along the I-76 south to Colorado Springs and Limon.
Winter weather advisories and winter storm warnings are in effect across large swathes of the region for Wednesday, and in some cases Thursday.
"The forecast has been updated for more snow further north across the Denver metro area and the I-76 corridor," an NWS forecast issued by the Denver/Boulder office at 8:43 p.m. MST on Tuesday said.
Winter weather advisories are now in effect for these areas until at least 11 p.m. Wednesday.
"The heaviest snow is still expected to be from between Denver and Colorado Springs east towards Limon and Akron," NWS Denver/Boulder said in the 8:43 p.m. update. "Snowfall amounts of 6 to 14 inches are expected in these areas. There will be a range across the Denver metro area with somewhere between 2 and 6 inches in the northern suburbs and 6 to 12 inches in the western and southern suburbs."
In a further update issued at 9:36 p.m. MST, the NWS said: "Heavy snow will fall through late Wednesday from the mountains west and southwest of Denver, between Denver and Colorado Springs, and east to Limon and Akron. There will be a sharp gradient in snow on the north side of this band, over Denver or just north of the city, and along I-76, with much less snow and little impact further north."
In Denver, its western suburbs and Boulder, travel could be "difficult" on Wednesday, according to an NWS Winter Weather Advisory issued at 7:55 p.m. MST on Tuesday.
"The hazardous conditions could impact the Wednesday morning and evening commutes," the advisory said. "Slow down and use caution while traveling. The latest road conditions for Colorado can be obtained by calling 5 1 1 or by going to www.cotrip.org."
Winter weather advisories are also in effect for the I-70 mountain corridor to the west of Denver until 11 a.m. Wednesday with additional snow accumulations between 3 and 6 inches expected.
"Snow-covered roads will make travel hazardous," the NWS said.
In addition, winter weather advisories have been issued for the southern Front Range foothills in effect until 11 p.m. Wednesday, with total snow accumulations between 6 and 12 inches expected. Again the NWS warns that snow-covered reads will make travel hazardous in this area.
There is still much uncertainty regarding the forecast for Thursday and Friday in Denver and the surrounding region. The NWS said there is "potential for heavy snow but we're not sure where the storm is going."
"It could be nothing or a significant new snow storm."
