Forecast Discussion:
I'm on the road again Tuesday night, so I'm just going to focus, graphically, on the Thursday/Friday early AM snow chances. Before that, we just might tie or exceed the DIA record of 80F for Wednesday. It is always the hottest before the storm. With some windy conditions and that dry heat, fire danger will be elevated across the Front Range today.
In the longer range:
The National Weather Service is not excited about snow on Thursday - but mention a chance of rain and much colder temperatures and wind (get those long pants out and find your coat again). Figure 1 is the GFS total snowfall predication and puts Longmont at around 2 inches. The WFR model (Figure 2) puts us on the edge of snow and no snow (due to temperatures) but a Trace to an inch is possible. Figure 3 is the same with the NAM model and has us around 1 inch of snow. The weatherunderground model doesn't drop the temperatures in Longmont low enough for snow until the precipitation chances drop to almost zero. So no snow or just a dusting according to them. Finally, the Weather5280 snow gamblers chart makes a Trace likely, but any more snow than that very unlikely.
More tomorrow!
