Old rule of

, is the NWS so devoid of funding that we're basing forecasts on rules of thumb from the 1960s?

I'm snowboarding to work via the loop on Friday morning.

The temp in the upper layers matter more.

NWS discussion here points to a better possibility of snow down in the Matagorda bay area and down to Corpus. Expecting the moisture to depart here before the coldest air moves in. Even so, I'll be watching for a flurry on the way to work Friday morning.

This is correct. I can remember it snowing at 37 degrees when I was young. Then in 2008 it snowed its arse off in the BR area with the temperature sitting right at 34 degrees the entire time. And it fell so fast that it accumulated on ALL surfaces up to about 3 inches in the LSU area.
32 degrees and below certainly helps but it doesn't HAVE to be at or below freezing. If the upper and middle layers are at or below freezing, precip WILL fall as snow as long as the lower levels are in the mid 30s or lower.

All this very cold weather rolling in now basically guarantees some muggy, sweaty carport type weather for Christmas, right?
Posted on 12/6/17 at 9:03 am to bayoubengals88
Aside from wet bulbing, can snow cool down the surface layer? I'd assume that heavy enough snow through a thin 34 degree surface could cool it down to below 32, including the surfaces it lands on.

$10 says there will be no school all in the SE Louisiana Friday.

Oh for sure. Christmas will be 78 with a 100% chance of swampass.

What's the consensus here snow or no snow?
