Looking ahead to October: Climatology and this year’s outlook

September 30, 2016 / Ben Castellani

While the fire ban has been recently lifted in many Front Range counties, September did little to relieve the parched landscape with yet another month of well below normal precipitation. Will October offer up the soaking rain and mountain snow that we desperately need? Read on as we examine Boulder’s climatology and consider the current state of the atmosphere to give our outlook for the next month.

Why does the “true” fall equinox in Colorado occur four days late?

September 26, 2016 / Ben Castellani

We have all come to accept that the bi-annual occurrence of the equinoxes signifies the day when every location on Earth experiences exactly 12 hours of day and 12 hours of night. We examine why this ubiquitous belief really isn’t correct and explain why today is our “true” date with equal amounts of day and night.

After a cool and “autumn-like” weekend, this week will feature milder temperatures and lots of sunshine, at least through midweek. A fly in the ointment will be a weak system approaching from Baja California which will increase clouds and lead to the chance of isolated rain or storms late in the week. These should be confined mainly to the mountainous areas, however. Read on for our full weekly forecast to end the month of September!

Dry weather has prevailed across northeast Colorado for the last several days, with temperatures moderating from the 60’s to near 90 degrees. This trend continues through much of this week’s forecast as a flat upper-ridge dominates our weather.

After a warm final day to the weekend, one which Boulder set a record high at 92 degrees, this week is slated to turn much cooler starting this afternoon. Temperatures will be coolest on Tuesday with highs below seasonal norms and overnight lows falling Tuesday night likely into the lower 40’s on the Plains. This is all in response to a strong cold front pushing south from Wyoming. With the front also comes the chance of rain and storms but these look to be hit or miss through the week. Read on for the week’s forecast in its entirety!
