Up to 6″ Snow Yesterday-Lastnight In Northeast Jasper County………2-6″ Looks Good for Friday with Heaviest Totals From Far East Areas to OhioJanuary 24th, 2013 at 3:17 pm by Chad Evans under Chad's WLFI Weather Blog
2″ to as much as 6″ of snowfall fell in our far northwest yesterday lastnight. The 6″ (Wheatfield CoCoRaHs report) occurred in heavy lake effect snowfall lastnight & verified per Doppler radar.
Here at WLFI, we had just a light dusting (trace) that looked like bleached flour tossed of the pavement & powdered sugar dusted on the grass.
U.S. NAM model is back to nothing for us tomorrow or very, very little. It is the only model, other than our Futurecast, doing this. If these models are right, I will be shocked.
NWS has 1-3″, which lines up with the 2-3″, but I put more in our eastern counties with that 3-5″ & then two bands of up to 6″, as I think some of that heavier snowfall that is forecast for eastern Indiana & Ohio sets up a little farther west. I like the direction NWS Eastern Indiana/western Ohio is taking with potential of isolated 5, 6″ amounts with banding features. I think some of these mechanics will nudge into our east.
I like 2-6″ of snowfall with the 2″ amounts in the western half & the higher amounts in the east with two bands having the best chance of a 6″ amount. I like 18:1 ratio, so we can squeeze 2 or 3″ out of 0.11-0.16″ of liquid. Same for 4″ amounts, we can squeeze that much snow out of 0.18″ of liquid in this case.
The snow will be very fluffy & have lots of air in it due to its frontgenic properties & ratios. In fact, in an area that gets 3″, it may settle & shrink to 2″ by Saturday due to the air in it.
Cut from 3-6″ to 2-6″ due to higher forward speed in our western counties. Most of it will fall Friday morning.
Looks to be two bands of really good frontagenic banding one near Rochester & another near Windfall.
