In Brief:

Today, will be chilly with a high in the lower 60’sF. This front pulls away overnight and we warm to nearly 80F Monday. A cool/wind shift comes through in the evenings Monday and Tuesday keeping the warmth a bit tempered. We return to highs near 80F for the rest of the week and afternoon thundershowers coming off the mountains each day.

8:30pm Update:

Everything is on track after a chilly Sunday. We will rise to upper 70’sF for a high on Monday with dry conditions. I’m going to go play board games with the family instead of load a bunch of graphics about nice weather here tonight. Have a nice week everyone.

End 8:30pm Update.

Forecast Discussion:

We have a little chance of a shower now and then in the cool air today (Figure 1) but the front is far to our south and east. The stratus clouds of the morning will give way to partly cloudy skies later today.

The Longer Range Forecast:

There isn’t much to cover at this point – a couple of wind shift lines (weak fronts) will come through Sunday PM (and bring warmer air back) and Monday and Tuesday PM. We will approach 80F Monday right after our chilly Sunday (Figure 2). We will see things cool slightly to the mid 70’sF by Wednesday – then stabilize around 80F with a return of wandering afternoon thunderstorms. Enjoy your weekend! (Sorry this went up later than normal on Sunday – I couldn’t reach the editor tool for some reason last night. )

John Ensworth works from Longmont as the Principle Investigator for the NASA Science Mission Directorate Earth and space science education product review through the IGES (The Institute for Global Environmental Strategies – . 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.
