Forecast Discussion:

The peaceful weather rolls on.  The dry cool front of Saturday has made it to Mexico
(Figure 1) leaving us to warm up with down slope winds today/Monday.

The longer range forecast:

Figure 2 shows the weather trends for the next 10 days… I’ve drawn in the two cool fronts that are forecasted to come through next- when ripples in the westerly upper level flow (yesterday’s forecast discussion) pass over Colorado.  We’ll almost hit 70F on Monday! Later on Tuesday another dry cool front drops us 15F, but not much else happens.

The cold front late Thursday into Friday AM will create more snow for the mountains, and a very small chance (at this time) of showers down along I25 – and some better winds.  We do stay more consistently cool after that front though.  Still very quiet around Longmont.

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.
