Hello Fall: A look back at August and ahead to September

September 1, 2016 / Ben Castellani

Let us be the first to welcome you to fall! That’s right…summer is no more, at least to us weather folks. September 1st marks the beginning of meteorological autumn. Picture-perfect weather has been a mainstay throughout the summer, which is both good and bad. The monsoon plume has largely been confined to our south and west, keeping the Front Range relatively parched, leading to dry and at times, dangerous fire conditions. Will this trend continue into September? Read on as we examine Boulder’s climatology and consider the current state of the atmosphere to give our outlook for next month.

Drought officially returns to Colorado; limited respite in sight

August 17, 2016 / Ben Castellani

Summer is the one time of year when you don’t need us meteorologists. You already know the weather for today (and everyday) will start sunny, warm into the 90’s, then promptly cloud up and produce a brief storm which generates a “just okay” rainbow before another stunning Colorado sunset. If it feels like we’ve been enjoying a much nicer, less rainbow-filled summer than normal, you’re not alone, nor imagining things. It’s been dry. Historically dry.

We discuss the official return of drought to Colorado and provide our thoughts on the outlook heading into September.

This week in weather: August 8, 2016

Following four days of unseasonably cool temperatures, this week begins warm as moderately-moist southwest flow dominates the region. By mid-week, moisture associated with two tropical cyclones spreads into Colorado alongside a cold front from the north. With this, we’ll see storm chances increase and temperatures fall once again. Read on for our complete weekly outlook.

Over the course of the last week, we’ve seen the beneficial summer rains spread across much of the Denver Metro area. The week ahead will see the plume of monsoon moisture shift westward, bringing a period of temporary drying to our region. Read on for all the details, including the extent of the heat and when we think the monsoon rains will ramp back up.

Hurricane Season 2016: Activity to pick up in the Atlantic

July 5, 2016 / Matthew Steiner

Last summer, the story was an El Niño-induced lull over the Atlantic Basin, but as we discussed in an article last week, El Niño is officially gone. What exactly does that mean for tropical activity in the Atlantic? Are there other climate signals that might govern this year’s tropical development? We bring you up to speed on the 2016 Atlantic Hurricane Season and our expectations moving forward.

Summer 2016 Outlook: The afterlife of the strongest El Niño on record

June 30, 2016 / Ben Castellani

The El Niño that has been with us for the last seventeen months has finally met its demise. The atmosphere is in the process of responding to this change as we speak. We provide an update on the situation as we begin our transition into a La Niña pattern. We also review how well our late-winter predictions verified. Read on for our full outlook for the remainder of the summer season.
