... Today in Metro Denver weather history...
21-23 in 1918... Post-frontal snowfall totaled 5.9 inches in downtown
Denver. Most of the snow... 5.3 inches... fell on the 22nd.
North winds were sustained to 20 mph on the 21st.
In 1931... a major storm dumped a total of 13.2 inches of
snowfall over downtown Denver. Most of the snow... 11.4
inches... fell on the 21st. A very cold air mass settled
over the city after the heavy snow on the 21st. After a
low temperature of zero... the temperature climbed to a high
of only 5 degrees on the 22nd... a record low maximum for the
21-25 in 1952... snowfall of 6.2 inches was measured at Stapleton
Airport where northeast winds gusted to 17 mph on the
22-23 in 1953... strong winds raked Boulder causing 18 thousand
dollars in damage. Wind gusts to 80 mph were recorded at
Valmont and estimated to 80 mph at the Boulder Airport.
23 in 1899... a trace of snow fell in the city. This... together
with a trace of precipitation on the 16th and 21st... was the
only precipitation of the month... making the month the driest
on record. The record was equaled in November of 1901 and
1949. This trace of snow along with a trace of snow on the
21st was the only snow of the month... ranking the month the
2nd least snowiest on record. This record was equaled in
November of 1884... 1901... 1905... 1917... and 1939.
In 1901... northwest winds were sustained to 45 mph with gusts
to 53 mph. The Chinook winds warmed the temperature to a
high of 70 degrees.
In 1910... west winds were sustained to 42 mph. The Chinook
winds warmed the temperature to a high of 67 degrees.
In 1959... west-northwest winds gusted to 56 mph... briefly
reducing the visibility to 3 miles in blowing dust at
In 1998... winds... estimated as high as 58 mph... caused
several wood trusses installed in a police station
under construction in Castle Rock to collapse. A
construction worker on the roof received minor injuries
when he was struck by one of the trusses. Southeast
winds gusted to 38 mph at Denver International Airport.
23-24 in 1992... a pre-Thanksgiving blizzard belted Metro Denver.
Gusty north to northeast winds at 30 to 40 mph caused
near-whiteout conditions as visibilities were often below
1/4 mile. The strong winds drove snow into drifts of more
than 4 feet. Hundreds of Holiday travelers were stranded
when airlines canceled flights at Stapleton International
Airport where snowfall totaled 7.6 inches and north winds
gusted to 37 mph. Blizzard conditions began around mid-
morning on the 23rd and ended by mid-afternoon... but heavy
snow fell through the night. Snowfall totaled: 12 inches
at Conifer... Morrison... and wheat ridge; 19 inches at
littleton; 16 inches at Castle rock; 9 inches in brighton;
8 inches in aurora; and 6 inches in Parker.
In 1993... a moist upper level disturbance dumped heavy snow
over most of Colorado. Snowfall amounts averaged 5 to 8
inches across Metro Denver. Snowfall totaled 4.6 inches
at Stapleton International Airport where northeast winds
gusted to only 20 mph on the 23rd. The very cold air
mass caused the temperature to dip to a record low of 8
degrees below zero on the 24th. The temperature that day
climbed to only 9 degrees... also setting a record low
maximum for the date.

Area forecast discussion National Weather Service Denver/Boulder Colorado 359 am MST sun Nov 23 2014 Short term...(today through tonight ) issued at 359 am MST sun Nov 23 2014 Strongest wave of moisture and energy is moving across the forecast area early this morning. There is a secondary wave noted in far northwest Colorado/northeast Utah/southwest Wyoming which will reach the forecast area later this morning. In between... there is slight drying so will see a temporary decrease in snow intensity across the mountains early this morning. On the plains...precipitation was blossoming on the Palmer Divide area and this area should continue to affect mainly areas south and east of Denver through early morning. There may be some redevelopment behind the main feature as large scale lift is still seen in the q-g fields this morning...but overall latest profiler data shows winds a slight westerly component just off the deck which would limit any precipitation redevelopment from Denver north. Could see a couple quick inches of snow accumulation due to intensity of precipitation on the Palmer Divide area...mainly above 5500 feet where temperatures are cold enough. Otherwise...the precipitation on the plains will likely come to an end by middle morning as flow turns more north/northwest and some drying occurs behind first wave. Windy conditions will develop most areas and remain in place through the afternoon. With some sunshine returning and steep lapse rates...should see isolated showers redevelop this afternoon...mainly snow due to relatively low wet bulb zero heights. Again these would favor the Palmer Divide area. Mountain locations would also see a kick up of snow intensity with more of a convective scenario getting underway this afternoon. Those are expected to decrease in intensity this evening then as airmass stabilizes...only to have more widespread snow redevelop before daybreak Monday as another wave moves into the area in northwest flow aloft. Heaviest snow with this event occurred in the early morning hours...but impacts will remain in place through today and tonight and heavier snow expected again tomorrow so will leave warnings for the mountains and advisories in place for the High Mountain valleys. Generally look for another 2-4 inches today and another 2-4 tonight on average above 9000 feet. Finally...should see the wind increase again later tonight as mountain top stability profile becomes more favorable but still marginal with high country snow. The strongest winds with gusts in the 55-65 miles per hour range will remain in the higher elevations but areas right next to the foothills could see a few gusts into the 30-50 miles per hour range. Surface gradients are a little weak so that should help the stronger winds stay up high. Long term...(monday through saturday) issued at 359 am MST sun Nov 23 2014 Northwesterly flow aloft will remain over the area on Monday as weak disturbances embedded in the flow move quickly across. Moisture depth will improve in the mountains with favorable lapse rates and orographic component so should see periods of MDT to heavy snow through the day with considerable blowing snow. At lower elevations steep lapse rates will combine with abundant middle level moisture and passage of disturbance in the afternoon to allow for at least a slight chance of -shsn over northestern Colorado. Gusty north-northwest winds will continue as well. Highs temperatures will be a few degrees colder as readings stay in the upper 30s to near 40. There could be a brief period of stronger winds in and near the foothills Monday morning which may get close to high wind criteria in the typical windy spots. By Monday night moisture will begin to decrease in the mountains with lapse rates begin to stabilize thus snowfall should begin to decrease however it will remain windy with areas of blowing snow. Although a mountain top stable layer will be present component along winds are only forecast to be in the 35 to 40 knots range so threat of high winds looks low at this time. On Tuesday moisture will increase once again in the mountains in northwesterly flow however lapse rates will be poor so additional snowfall will be on the light side. Once again will see areas of blowing snow. At lower elevations it will be dry with gusty west-northwest winds at times. 850-700 mb temperatures begin to rise which should allow for readings to rise back to seasonal normals. For Tuesday night into Wednesday persistent northwest flow aloft will continue with some moisture embedded in the flow. Although orographics will remain favorable lapse rates will continue poor which should limit accumulations in the mountains meanwhile latest data suggest an increasing threat for a high wind event for areas in and near the foothills Tuesday night into Wednesday morning as Strong Mountain wave develops and combines with decent low level pressure gradient. Component along winds are forecast to be at or above 65 kts by 12z Wednesday. As for temperatures with downslope low level flow increasing on Wednesday this may lead to much warmer highs especially alng the Front Range as readings approach 60 degrees. Meanwhile further east over the plains readings may stay in the lower 50s near the Wyoming-NE border. By Thanksgiving day there is no agreement at all between the longer range models. The European model (ecmwf) has flip flopped back to its previous solution of a few days ago as it brings a cold front into northestern Colorado during the day. Meanwhile the GFS has strong downslope warming across northestern Colorado with the fnt staying way off the east of the area. To complicate matters even further the Gem and NOGAPS show a strong cold front moving into northestern Colorado by Thursday morning. As a result temperature guidance for Thursday is all over the place with highs ranging from the 20s to near 70 depending on which model you want to believe. In addition the Gem and NOGAPS show a strong upper level jet in northwesterly flow over the area which would enhance snow potential if the fnt comes in like they show. The European model (ecmwf) for now at least keeps the jet further to the north with precipitation staying out of the area. At this point will go with an in between solution until it becomes more clear what is going to transpire. Thus will keep a dry forecast with readings ranging from the middle 40s over the far northestern plains with 50s closer to the foothills. The same issues continue on Friday as the GFS has a flat upper level ridge over the area with highs in the 60s to near 70 over northestern Colorado along with dry conditions. Meanwhile the European model (ecmwf) has another surge of colder air moving into northestern Colorado with the upper level jet sagging over the area with a chance of snow. The Gem keeps the cold air over the areas as well but has no precipitation. Once again will just broadbrush the forecast for now. && Aviation...(for the tafs through 12z Monday morning) issued at 359 am MST sun Nov 23 2014 Most rain/snow showers will be shifting to the south of the Denver metropolitan area and Front Range airports through 13z. Only isolated showers expected at this time. Mainly VFR conditions will prevail with a chance of lower MVFR ceilings if low level winds turn sufficiently upslope. Expect mostly a scattered-broken middle level cloud deck around through the day...and another but slight chance of passing light snow shower 20z-01z as airmass destabilizes. Strong north winds will be the main feature with peak gusts reaching 30-35 kts from the north between 16z and 00z. Then winds subsiding and turning more westerly overnight at 10-15 kts. && Bou watches/warnings/advisories... Winter Storm Warning until 5 PM MST Monday for coz031-033-034.
