In Brief:

A little bit of tropical moisture is leaking into the state up the Rockies under an upper level ridge that will strengthen and weaken, off and on, this week. The low to mid 90’s and a daily chance of afternoon storms will be the norm. The summer doldrums are here.

Forecast Discussion:

I can’t add much to the In Brief this time. We will see afternoon storm chances (non severe) and mid 90’s F this weekend (Figure 1). Remember, lightning is dangerous no matter how small and mundane a thunderstorm is.

The Longer Range Forecast:

We will see 100’s F out on the eastern and southeastern plains with toasty 90’s F all week. The ridge will get stronger Thursday and Friday – storms will diminish even more and we’ll make a brush with 100°F.

He is in his 14th year running this review. He is an astronomer (from the 2nd grade onward) and became a meteorologist (in the 5th grade) when a thunderstorm in Arizona rained on his telescope when the weather service had only forecasted a 10% chance of rain. He has college degrees in physics and astronomy and climatology and a graduate degree in meteorology and earth science. He lectures at the Little Thompson Observatory in Berthoud, the Estes Park Memorial Observatory in Estes Park, and for a number of online universities. He built and runs a backyard observatory near Pace and 17th in northeast Longmont where he has lived for 8 years with his wife, daughter, son, and two cats. Invitations to open house nights at this observatory, LTO, and EPMO will be posted with future discussions when they are scheduled. Forecasting severe weather and snow amounts via text lead to this column. He began texting friends about the weather right after the September 2013 flood. The readers of this column will, hopefully, keep him honest in what he ‘thought’ he had forecasted for ‘the most recent’ storm.
