What time the snow/sleet will hit southeast Louisiana?
I live 60 miles Southwest of New Orleans. Just north of Houma in upper Terrebonne Parish. It is 8:15 p.m. now. What time should any of the white stuff fall? Or will we luck out again? The radar looks promising. Just nothing happening yet. I am so impatient! I hope it happens just in time for midnight mass. That would be so beautiful walking to the church with snow flakes falling!

I'm surprised that nobody's seeing anything in LA right now. I guess some of that's got to do with the low dew points. Hopefully they'll work their way up soon.

AL Chili Pepper is right. My dew point here is still 22. Lots of dry air, which explains why a lot of this isn't reaching the ground.

I'm surprised as well.
Is ANY of that over towards Lake Charles reaching the ground? That's the area that gave the Houston area the accumulation.
I think that's your best shot, it just seems the air is drier farther east. Evaporative cooling should eventually be able to spit out something though.

I know the latest radar imagery looks VERY nice across LA but there is a problem in the form of dry air. this was handled well by the 0z RUC and clearly evident below 900mb on the LFT sounding. as a result as the precip is falling into the dry layer it is evaporating but at the same time helping to increase the dry portion of the column. once the dry air is sufficiently saturated precip will reach the surface. this should take place pretty soon.

P-type should be all snow after 100AM over the region. And you actually might see some impressive snowfall rates in heavier bands. I noticed that the best RH and lift may for a short time coincide w/ the dendritic layer as evident on BUFKIT time-height sections at LFT (Lafayette, LA).
Also BIG flakes not out of the question given favorable crystal type, and riming.
Furthermore, plenty of speed shear is evident, and ascent is nearly moist adiabatic. As a result more of the same CSI banding which took place over TX this morning and early afternoon could once again occur here resulting in localized impressive accumulations.

Now it just needs to mosey on east.
