Steve McCauley goes with less frozen precip in DFW metro that the NWS update of 2 hours ago just to keep the roller coaster of emotions going.
Also a little more info on how his stat method is run:
Rain showers will be with us on and off through tonight into tomorrow morning, and then our cold front sweeps through before lunchtime causing temperatures to fall into the 40s during the afternoon and down into the low to mid 30s by Wednesday morning (should stay ABOVE freezing for the eastern half of the immediate DFW area and just barely at or slightly below freezing for the west). With the temperature near freezing for the western half of the area, sleet, freezing rain, and snow still look likely for those areas while a cold rain with an occasional sleet pellet can be expected in eastern areas.
As mentioned yesterday, since we are still more than 24 hours away from the start of the winter precip, specific amounts cannot be accurately predicted. But even though specific amounts will have to wait until tomorrow's forecast, I can say - using the words I posted in yesterday's forecast - that amounts of winter precipitation look to be "TRIVIAL" (i.e., less than an inch) for most of the Metroplex, with the best - but not only - of the ice and snow to the west and northwest of the DFW area.
Although the precipitation will come to an end Wednesday night, temperatures will fall below freezing even in the heat island of the Metroplex by Thursday morning, so any standing water could freeze.
It should come as no surprise that the latest American Model this evening has now come around to what the Stat Method and nearly all other computer models from around the world have been predicting for the past several days: little to no snow for the Metroplex.
What a turnaround for the American Model! Going for up to a foot of snow in its forecast from just a couple of days ago to less than an inch with its latest outlook. Oddly, and as mentioned in yesterday's post, there never seemed to be data to indicate such a heavy snow event could occur, so it is unclear why that model was insisting this was going to be a snowpocalypse for DFW.
Now you know why the Stat Method completely rejected this scenario. Keep in mind, the Stat Method is NOT a computer model. It is simply a statistical analysis of ALL computer models from around the world, and it tries to tease out the most accurate forecast possible since no one model is consistently right all the time (and neither is the SM I admit).
But when one of those models is going for something so "out there" that it strains reason and accountability, the Stat Method gives that model a weight of ZERO in its contribution to the forecast and effectively gives it the boot, and thus it has ZERO impact on the outlook given by the Stat Method.
There now...having said all that....time for Mom to turn around and hit us all with a blizzard!
