End of the 03z HRRR is wild. Transfer of energy from one sub-980 Low to another. Like a nor'easter in the Midwest. Secondary Low causes temperatures to crash.
If the NAM and long range HRRR and RAP are the only models not showing high totals then that's a good thing. Looks like globals and even HRDPS and FV3 really hammering most of NIL with heavy snow.
Anyone catch Tom Skilling mention this yet? One of my favorite memories was him discussing the GHD blizzard as soon as the EURO starting showing it a long ways out.
Not to take away from the possible snow, but the cold forecast after this storm looks really impressive. GFS shows below 0 wind chills from 1-13-24 through the end its run...
Was gonna comment how confused I was reading that. Seems like things trended wetter and maybe snowier across much of the area. I thought 6:1 ratios were expected all along.
NAM says shift the WSW southeast in Illinois. Maybe NAM is just being NAM though but some other CAMs also are trending this way. Fingers crossed in the city.
Regardless, good to see the continuing trend on global, regional, and mesoscale models. I doubt the globals will handle the rapidly deepening and occluding of the Low very well which will factor in where the final deformation axis resides
We'll have to wait and see how these two storms this week turn out but wow at the modeling a week plus out showing the possible solution to both storms and ensembles mostly staying the course for both storms. Models have really come a long way.
Looking like this storm will cause quite the severe outbreak and high winds to the south and east. I'm thinking there will be some surprises with the cold sector due to the excess rain and storms in the warm sector. Would not want to be LOT having to make the call based on the potential cutoff potential if the two waves of precipitation manage to overlap or completely miss some counties.
