LOT sticking with global models.
The
forecast for this storm system continues to be handled best by
the more consistent global forecast models and ensembles
(especially the ECMWF and its ensemble members). We therefore
continue to steer the forecast in this direction. Currently, many
of the higher resolution models such as the HRRR, NAM and RAP
continue to be northern and warm outliers with the system, and
thus, their current iterations are not favored.
Anyone have a good memory of the 12/15/87 that they are comparing this too?
confidence continues to increase that this anomalously strong storm system (which bears a striking similarity to the heart attack snowstorm of Dec 15, 1987) will produce major impacts across much of northern IL into Saturday morning.
