First Snow for parts of NE Colorado

A strong winter storm system slammed the state of Wyoming and especially Black Hills area of South Dakota with many locations reporting snowfall of over 1″ and in some casts in the Black Hills over 3′ of snow!  Here in Colorado we were brushed with the southern part of the system and received some snowfall, heaviest over the NW mountains with some minor accumulation on grass along the I-25 corridor.  Temperatures dropped well below freezing many areas as the storm pulled away Friday night also making it the first freeze of the year for lower elevations.  The foothills and Palmer Divide experienced a freeze the last week of September.  Below are some of the snow reports in the area from the NWS in Boulder:

Broncos Game Day Forecast

Cannot really ask for a nicer day for this time of year as high pressure building over the state of Colorado will provide sunny to mostly sunny skies, warm temperatures and dry conditions.  Temperatures will be warming into the upper 70s to around 80 for kickoff with temperatures in the low 80s during the game.  Relative humidity values will be in the lower teens when temperatures are near their peak.  Winds will be light from the S with some variation from SW to SE at times in the 5-10mph range.  GO BRONCOS!!!

First Snow for Parts of Colorado and First Freeze/Frost for Many

The mountains of the state have already seem multiple rounds of snow above treeline with the last snow producing some minor accumulations into the higher foothills but this incoming storm system will produce snow as low as 6,000-7,000ft for some areas of Colorado today and tonight.  The storm system will pull away late tonight with clearing skies leaving many areas prone to the seasons first freeze/frost especially over the Palmer Divide and Front Range foothills but even low lying areas of the northeast plains such as Greeley and Limon may dip below the freezing mark briefly.  The heavier snows will be above the 9,000ft level helping the ski resorts out to what could be an early start to the ski season!  Minor snow accumulations of 1-3″ are possible in cities such as Conifer, Nederland, Estes Park and Evergreen.  The sun will come out tomorrow and melt much of the new snow with mild conditions returning through the middle part of next week.  Another storm system with the potential to produce snow at even lower elevations will move into Colorado this time next week.

There are currently winter weather advisories in place for much of western Colorado and frost and freeze watches and advisories in place for lower valley locations out west and for portions of the NE plains and Palmer Divide.  Take precautions today if you wish to protect tender vegetation tonight and tomorrow morning.

City of Boulder Sets ALL TIME and MONTHLY Precipitation Records!

The City of Boulder has reported a new record of 29.65″ of precipitation so far in 2013 and there are more than 3 months left this year!   The old all time record was 29.43″ set back in 1995.  The all time monthly precipitation record of 9.59″ was also smashed and the monthly September precipitation of 5.50″ pales in comaprison to teh new record of 16.69″ and there are still two weeks to go!  Many other areas of Colorado have likely set new monthly precipitation records.  So far DIA has reported 4.65″ of rain in September only 0.02″ away from the all time record of 4.67″ just a little more rain and this record will fall as well.   Unfortunately DIA does not represent the entire Denver Metro area appropriately with some areas in Aurora experiencing 14-18″ of rain.  Below is the Public Information Statement from the NWS in Boulder:

An Amazing Monsoon Season for Flagstaff, AZ and the Desert SW

After a very dry June the monsoon season kicked off during the month of July with heavy flooding rains which continued sporadically through August and now into September.  The flash flood season was unusually high for parts of the Country that “normally” do experience much rainfall.  There are always floods during the SW monsoon season but the frequency and severity of floods was higher this year.  Recent burn areas from forest fires also contribute to the flash flooding problem as it does not take as much rain in a burn area to produce flooding.  During the month of June Flagstaff, AZ collected 0.03″ of rain but during the month of August 7.57″ of rain was officially reported at the airport.  The month started off with a bang with 1.76″ reported on the 2nd.  23 out of 31 days during the month reported at least a trace of rain.  During the month of August 4.85″ of rain was reported but there was not a single day with over 1″ of rain.  The rain fell with frequency once again with 22 of 31 days reporting at least a trace of rain.  September so far has produced 2.65″ of rain up through the 10th in Flagstaff due to a slow moving upper level low pressure system importing additional subtropical moisture into the SW states.  For the month of July, August and up to September 10th Flagstaff has tallied 15.07″ of rain!!!  That may not sound like a lot of rain to people who live out east but the ones who live out west know how precious a commodity rain can be…  The monsoon will be shutting down in the coming weeks but it has been an impressive season during 2013.  More information about the SW monsoon and climate resources can be found by clicking here.

Lightning Delays Thursday Night Football

A thunderstorm developed south and west of Sports Authority Field at Mile High yesterday evening which caused a delay to the start of the game between the Denver Broncos and Baltimore Ravens.  Lightning was detected less than 3 miles from the field before the storm began to weaken with multiple strikes less than 4 miles from the stadium.  The delay caused only a minor inconvenience pushing back the start of the game.  The Broncos went on to annihilate the Ravens 49-27 with Peyton Manning throwing an NFL record tying 7 touchdown passes.
