Short Range Forecast Discussion
Short Range Forecast Discussion - Updated for Tuesday July 22, 2014 - High pressure ridging overhead continues building in strong today, plus we see drier conditions, for mostly sunny skies and a seasonally normal thunderstorm threat. Afternoon thunderstorm chances do increase slightly on this hot Tuesday though, but still isolated. Wednesday and Thursday look to be showery and cooler, with plenty of thunderstorm activity, as a weather disturbance and slug of subtropical moisture circulates into Colorado out of the southwest US deserts. Some good widespread showers are expected across the area. Friday through Sunday we see a warming and drying trend as high pressure ridging shifts to the southwest of the area (4-corners region), with less thunderstorms and more sunshine. CM

Long Range Forecast Discussion:

7 day to 2 week+ forecast (since 1998) - 27 July to 06 August, 2014 - Next Monday through Wednesday we expect an increase in thunderstorms and showers as moisture and instability increase. The rest of next week and through early August we see strong high pressure ridging across the west (centered mainly near the 4-corners region ~ AZ/ NM/ UT/ CO), with a low to mid grade monsoon pattern across the southwest US (Arizona/ New Mexico), feeding scattered (or better) thunderstorm coverage each afternoon across northern New Mexico, otherwise mostly sunny weather is expected, with near average temperatures. We will also have to watch for the influence of tropical systems, which would increase shower and thunderstorm potential further. CM

Longer Range Outlook

As of now, July 2014, we are still on a path to see an El Nino Sea Surface Temperature pattern develop across the Equatorial Eastern Pacific (SSTs near to slightly below average). In fact, as of the last check, all of May and up until the last check of the charts (July), we see a trend to warmer Sea Surface Temperature Anomalies (or at least warmer than average Sea Surface Temperatures (SST's) holding overall) across the eastern Equatorial Pacific (good sign).

Current SST pattern- La Nada

The larger time-scale SST pattern in place right now is still a cool phase PDO, or negative PDO, which stands for Pacific Decadal Oscillation. This is a more long term pattern (decades), and it has made any recent years El Nino SST patterns weaker.

To reiterate, we expect (and have seen) a trend toward positive SST Anomalies along the eastern Equatorial Pacific as of June 2, 2014 (SST's just west of South America along the equator are warming up, still). The likelihood of an El Nino pattern materializing by this summer and fall are becoming greater, now "likely". Forecasts from other agencies are calling for El Nino conditions to develop this summer and fall as well. This would favor the southwest US (including southern California and across to Taos Ski Valley, even Aspen, Colorado) for heavier rain and snow this fall and mainly winter (2014-2015), after a potentially wet monsoon summer across the southwest US including southern California through Colorado. Northwest US areas, and southwest Canada, along with northern Colorado through Wyoming and the northern Rocky Mountains, should see an active monsoon (thunderstorms and showers) this summer, followed by a drier than average, or near average snowfall winter (2014-2015). This is our outlook for now, and we will update as info becomes available. All of this information is generated in-house.

We will keep this outlook updated as more information becomes available. If you want to know when the snow is coming (and be able to set unlimited alerts for any resort), within 5 minutes or less of us (our our sources) entering the data into any of our forecasts, be sure to download the app.

Keystone is home to three magnificent mountain playgrounds—Dercum Mountain, North Peak, and The Outback. There’s something special for every skier and rider of any level at each mountain. There are more than 3,000 vertical feet and over 3,000 acres of bumps and bowls, glades and steeps, groomers and rollers to be experienced.
