End of January "clipper" threat


snowstormcanuck

Recommended Posts

Well the NAM finally got a clue with this clipper as of the 12z run. I suspect the SREF will soon get a clue too.

I'm calling for a high end nickel & dime event in Detroit (3-5"). I want a daytime event so I can actually see the snow fall, but I also want a nighttime event so the snow can accumulate efficiently.

best case sceanario it starts at 2AM ends around 2PM. Heaviest from 5AM-10AM would be the best scenario

LOT is calling for 1-2" of snow for tomorrow...

What are the odds of a storm of at least 6" affecting this region at this point in the winter? I am talking about a general 6" "spread the wealth" kind of thing dropping snow through IA, S MN, C and N IL, C and S WI, a N IN and MI? Just asking.....

With every forecast update for this area, they raise the temps for Thurs/Fri. We were at 29 just the other day, we are now progged for 34 on Thursday and 35 (I have heard highs of 37 already from some outlets) on Friday...

Precip chances however, seem to be slim for both days only a 20% chance of snow

You worry too damn much.

On Average a solid 0.25". Snow ratios around 13/14 to 1... solid 3-4 inches possibly as much as 5"

I hope so but I dont think we will get more than 2-3 inches. It's gradually weakening as it comes SE. Maybe the models are a bit off who knows but I'd feel better if it was gaining strength as it heads towards us.

Thanks. Any pockets of .25+ at all in the band? Probably in the lake effect and thumb areas.

Just by eyeballing the graphics, looks like pretty much all of the DTX Warning Area gets hit pretty equally. I have no way of seeing total precipitation, however, just the precip in 6 hour increments. I'll be taking a closer look at some airport codes before I make my forecast in a bit...

Why is it easier to get rain in the winter than snow in the summer?

Look at the average temps, even in the dead of winter the average high temp is about 10 degrees below freezing for MSP. Meanwhile in the summer the average low temp is about 30 degrees above freezing. Obviously there's more to it than that...but it's much more realistic that you're going to get above freezing in January than below freezing in July.

I see what your saying. Makes sense.
