Major Warming Trend to Unfold

Yesterday's snow event performed close to how Weather5280 expected it to. Most spots in the immediate Denver metro area reported 2-4", with higher amounts to the south and southwest of Denver (as we had indicated in our forecast) and towards the Foothills. Denver International Airport (DIA) recorded exactly 3" of snow, with just 0.12" of precipitation -- which works out to a high 25:1 liquid to snow ratio.

This may be the last snowfall for Denver metro, however, for the next 7-10 days, as the pattern shifts of one of much above normal temperatures across most of the western US and much below normal temperatures (and enhanced storminess) over the eastern half of the US.

Though temperatures are still cold today -- staying in the 30s -- we add another 5-10 degrees to those for highs in the 40s on Friday, another ~10 on top of that for highs in the mid-50s on Saturday, and yet another ~10 degrees on top of that for Sunday and Monday. All indications are that we may be well into the 60s both Sunday and Monday, and perhaps pushing 70 by Monday. Low 60s stay with us on Tuesday, perhaps falling back into the 50s by Wednesday. (For point of reference, our average high in Denver this time in January is in the mid-40s).

Get out and enjoy this nice stretch of abnormally warm (and dry) weather that's about to unfold over this weekend!

Snow-lovers, fret not, there are some indications that we may be looking at a pattern change towards possibly colder and stormier weather by the first week of February. We'll save those details for another post!
