Yes, but the Euro ensembles still look pretty good and the 12Z GFS, UK and CMC all show a snowstorm with varying details (GFS all snow, UK snow along and NW of 95/mix to the coast, and CMC snow NW of 95 with mix along 95 and rain for the coast). Also, the 18Z GFS is a major snowstorm (6-12") for most of our area and the NWS at 4 pm is largely discounting the Euro given their discussion, below, which is very bullish on snow (and they're not taking the mix/rain scenarios very seriously). We'll see of course.
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Looking towards the beginning of the week guidance is showing a
deep 250mb trough swinging through the central US. This sends a
strong 250mb jet over the region and guidance has shown the
potential for some weak cyclogensis to our south. The consensus
amongst guidance is that a low pressure system will form to our
south and stays to the south as it moves towards the northeast.
This keeps the forecast area entirely in the cold sector of the
system and in the right rear quad of the 250mb jet. That should
lead to broad synoptic lift and with moisture in place we may
see accumulating snow across the region. Based on the 06z
ensembles that went into the 13z NBM, the nearly the entire
forecast area has 50% chance or higher of exceeding 1" of snow
and given the area would be in the cold sector there would be no
immediate rainfall to melt the snow. Going a little bit higher
to the 4" threshold, probabilities of snowfall exceeding that
mark are around 20-30%. At this point limiting factors would be
the speed and location of the system rather than thermal
profiles. Will continue to monitor as the system gets closer as
there are bound to be numerous changes in track and intensity
given this storm is currently in the day 5 period.
