Update 3pm: The Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – October 14th, 2018

Forecast Discussion:

The storm is underway so I'll post later today.  Right now (after midnight) the high end snow totals, towards 5 or even 6 inches of snow is more likely for Longmont.  I drove home from the airport at 1am and it was a rough drive!

More later today!

Update 3:00pm

The storm is winding down mid-afternoon Sunday (Figure 1). The storm over-performed for areas north of Denver (but the storm was still ongoing and sinking south at the reporting time of 7am).  I inserted my forecast in red next to the actual up-to-7am reports.  Figure 2 is Boulder county - Longmont saw 5-8 inches.  Boulder received 5-10 inches.

Figure 3 shows Boulder receiving 4-8 inches while Estes park saw 6-8 inches and Berthoud picked up 3-5 inches.  Figure 4 is the Denver Metro (where the snow was still coming down heavily) only had a few inches across the city.  More tomorrow on the later snow totals.

Figure 2: The CoCoRaHS snowfall reports up to 7am Sunday (the storm continued to roughly 1pm) for Boulder County.

Figure 3: The CoCoRaHS snowfall reports up to 7am Sunday (the storm continued to roughly 1pm) for Larimer County.

Figure 4: The CoCoRaHS snowfall reports up to 7am Sunday (the storm continued to roughly 1pm) for Denver Metro.

The longer range forecast:

The weather becomes almost completely dry again (just a few model runs have slight rain chances this week - Figure 5) after today.  Temperatures begin a steady climb to around 60-65F for highs and level off.  Quietness will rule.   The 10/15 update will be posted midday when the new storm totals come in.

** A reminder, this column will take it's first full break for a family vacation from Friday Oct 26 to Nov 4th.  **
