Weather to speak of...

Short Range-
Some weather moving through the Denver area tonight. Cold front currently located at this hour across northern CO with surface Low pressure in SE CO giving N to NW winds across Metro area tonight. Frontal passage expected before midnight tonight with increasing clouds over night along with stronger winds during passage. Early morning cool rain showers expected along with strong N winds lasting through morning hrs with partial cloud clearing by late afternoon. Strong surface High pressure to our N will push surface Low out east of CO and gradually clear through the day.

Long Range-
Looking into the rest of the week, this weak system will exit and be replaced by High pressure which will influence a NW wind and a fairly mild end of the week. A small frontal system will remain to our north as a very strong High pressure will remain over Mexico for Friday afternoon and Saturday. Sunday afternoon the winds will pick up with a stronger pressure gradient in place ahead of the next system to move in for Monday. Frontal passage appears to be around mid-day on Monday with post frontal precipitation in the form of snow Monday evening, but only light accumulations with this system. More details to come...

Week of October 28

Short Range-
After a nice weekend a high presssure ridge will continue to dominant over Colorado before a weak little disturbance to our north brings cloudiness, cooler temps and a brief shower or two on Wednesday. Thursday looks similar with cooler temps and partial cloudiness.

Long Range-
Looking later in our week ahead, a system still looks like it will bring snow to our area but not as much as predicted late last week. Friday afternoon we can expect to see increasing clouds and colder temperatures with the frontal passage as the snow starts falling leaving 1-3 inches possible by Saturday mid-day. A high pressure will move back in for the rest of the weekend before another weaker system strolls by on Monday leaving a couple inches of snow throughout the day. Taking a glance at the models for the following week, there is a signiture of a major system moving down from Canada and bringing snow to much of Colorado. Right now the models are predicting this system to move in on Friday 11/9 and clear out by late Saturday 11/10. This system appears to dig pretty far south and bring in close to 8 inches of snow for Denver if everything pans out. We'll continue to watch this system as the models develop and become more precise.

Week of October 22

Short Range- Looks to be a nice warming week ahead after chilly night temperatures and snow from the weekend. A strong ridge will be in place over the Western US while a cutoff Low forms over the SE US and retrogrades westward.

Long Range- By Friday afternoon the cutoff Low will push northward over E Kansas and will also push most of the front, that was expected to impact our area, to the north leaving the tailing end of the front to sweep through on Saturday 10/27 bringing possible rain showers and cooling temperatures. The next major frontal system to watch would be on 11/2. A Low associated with this front stalls in a double barrel Low over Southern CO bringing a very good setup for abundant snow with an upslope component lasting through the weekend and clearing out by Sunday 11/4. Right now the GFS model shows the snow machine starting up on Friday 11/2 midday and increasing intensity Friday night into Saturday morning, and slowing down by Saturday night. Based on the current model run I have, I am projecting accumulations in the 6-8 inch range for the Denver area. This projection is a long range and will need to update timing and details of the system. Check back later for more details...

Short Range-
Frontal passage looks to be around midnight tonight with mostly Northerly winds around 15-20 mph after passage. 100 kt jet streak embedded in a piece of the jet stream down stream of the trough axis will add upper level dynamics and enhance precip effects of snow Sunday morning across the Metro area. The snow is expected overnight Saturday thru Sunday midday. Accumulations projected between 1-4 inches across Metro area with the higher accumulations closer towards the foothills.
Long Range-
So far looking fairly quite through next week with another frontal passage happening on 10/26, bringing possible snow with cold air mass. After that a Pacific cold front looks to setup in Eastern CO on 10/30, looks like mostly rain at this point but could definitely be an upslope event…more details to follow.
