This Week In Denver Weather History: Sleet, Heat And The End Of A Record Dry Streak

DENVER (CBS4) - This week in Denver weather history includes plenty of wind, snow and cold, but it also features some record warmth and record dry conditions, too.

It's the time of year when strong downslope winds can develop and send temperatures well into the 60s, and sometimes, even the low to mid 70s.

While it has happened several times in Denver weather history, downslope winds made a big impact on temperatures back in 2005 when thermometers climbed into the 60s just about each day between Jan. 18-24.

In fact, the high topped out at 70 degrees on Jan. 20, 2005.

On Jan. 23, 1934, a 52-day dry streak came to an end in Denver. It's the longest period of consecutive days without measurable precipitation on record in the Mile High City.

That dry stretch began on Dec. 3, 1933.

When it comes to different types of precipitation, Denver can see a variety of things fall from the sky. But one of the most rare phenomena is sleet.

While graupel is sometimes called sleet, it's actually different by how it forms while falling through the atmosphere.

Sleet was recorded in Denver for 15 minutes back on Jan. 19, 1916.

Here is some more Denver weather history for this week.
