CENLA--just far enough north to get its share of bad winter weather, but not far enough north be out of harm's way when a strong hurricane moves inland.

Looks like I’m going to miss out on all the fun and have to keep going to work.

Weather Channel in BR shows it's barely getting below freezing three days in a row next week.




I was considering going out and buying insulation for my spigots but not with that forecast.

The GFS is a little wonky. It shows rain (not freezing rain) in areas that are WELL below freezing at the time.







No way rain falls in that area without freezing on contact. The GFS indicates freezing rain as the pink areas -- why wouldn't all of that be either pink (freezing rain) or purple (sleet)? No reason it should be indicated as plain old rain.

I say this to call into question these models. Even the models don't know what they're doing now



Edit: by the way, that's a good 6 or 7 hours of freezing rain for the BR area. That's still a recipe for major damage to the power infrastructure.

I've seen it rain at 28 degrees. Depends on the layer of air above, right?

That's kind of my point. Yes, it absolutely can rain at 28 degrees and even colder. It all depends the air above the surface. The point of my post was to call into question the GFS's rain and freezing rain depictions. Why would it indicate freezing rain in areas where the temperature is 28-32 degrees but plain old rain in the areas in the upper teens to lower 20's? Doesn't make sense. Freezing rain is rain that falls to the surface when the surface is at or below freezing, causing the rain to freeze on contact.

Upper atmosphere too warm, not cold enough to freeze before hitting the ground.

Don't worry, if temps are accurate we'll get plenty of ice on the power lines and knock out power.

We just got missed by the system that followed the Ohio River and dumped 10+ inches of snow around Cinci.

Now I get to tucker my a-hole again for the potential ice storm in the next 48 hours.

Clearing the drive off this morning in the dark was a blast. -16 in the sun on the way to work actually felt a bit balmy comparatively.

Omaha is forecasted to be sub-zero or single digit highs for the next 10 days

Unfortunately I got caught in freezing rain like that in Wichita, KS. 27 degrees and raining. Once the rain hit the ground it froze. I was on the interstate and it shut down. I made it to an exit at a crawling pace and the local high school opened the gym for people caught on the interstate in that area. I slept the night in that gym on a wrestling mat. At least it was warm.

Again, y'all aren't listening to what I said. I know what freezing rain is and I know what sleet is (and how each occurs). Sleet will fall only if the air above the surface is cold enough (which that's not likely). Freezing rain will occur if the rain falls through the warmer layers of the atmosphere above us and freezes upon contact when it hits the surface (which will be WELL below freezing in this situation).

My question was this:

Why would the GFS indicate freezing rain (pink) in the areas at or just below freezing but not in the areas further west where the temperatures at the surface will be WELL below freezing?

It doesn't make sense. Must be a glitch in the GFS algorithm or something.

Probably the model indicating convection currents lifting warmer air at the upper levels like an eddy current in water.

I know a few people living in the north and some of them are filthy during the winter. It's like they quit caring about cleanliness when the temperature falls.

Fun to see others from Cenla talking about this. I was a kid in Effie at the time and I will never forget it. Seems like it was two years in a row, but you may be right about 2 out of 3. Still have vivid memories of my parents pulling my sister and I up and down the driveway on a cardboard box
