Model QPF for the QCA has really jumped up since yesterday. It's looking like a very good chance at 10"+ now if the latest model solutions don't back off.
Many of the 06z models have bumped up QPF, with some now 1" or more. New Euro now has a band of 1-1.3" across much of the DVN cwa, so double digit totals seem a little more probable now, particularly in northwest half of the cwa.
Been focusing so much on the storm systems kinda forgot about all the cold coming down for next weekend and beyond. The western sub may have a hard time getting above zero for highs Sunday the 14th. Good chance at -teens early the following week. Gonna be a cold slap in the face after the recent warmth we've had going back through December.
Whatever snow falls across the sub will be around for awhile it seems.
DVN has the point/hourly forecast snowfall amounts up to nearly a foot here, and a few tenths over a foot for the QC. Seems pretty overdone as most guidance has QPF in the 0.6-0.9" range. Even accounting for higher LSR during intense banding, that may get canceled out by poor rates in the lulls in intensity many of the models show later tomorrow night into Tuesday. I'd probably go 6-8" with isolated higher amounts if I were making an official forecast. If the intensity of the deform band later Tuesday overperforms then DVN could end up being not too far off perhaps.
Yeah. I can see this being a situation where official totals end up north of 7-8" but for the casual observer it'll seem more like a 5-7" type of event. It's not realistic for me to be here every 6hrs to measure so I'm assuming my total will be less than DVN/MLI lol.
DVN all in with 7-12" forecast for the QCA. Southeast portions of the cwa are now in danger of some mixing/dry slot issues, but should still do pretty well there.
Marginal temps and relatively lower LSRs make it a bit tricky, but 5-6" for the QC looks pretty good at this point. Banding with the deformation should improve ratios though as RC mentioned earlier, so wouldn't be surprised if we can muster 7" or a little above if model trends hold.
Seeing a big signal way out in advance on many different runs of different models is a pretty big sign something big is going down. GHDI for example was seen a week plus out. Looks like we may have a real monster to track here boys.
The parade of potent systems showing up in the mid-range by all the models is very impressive. It's like we have a nice rally going in baseball. Keep the line moving.
