re: Snow Tease for Baton Rouge (Saturday) UPDATE (1/20)

I built a mount in my back yard. Two 8’ 4x4’s anchored in concrete about a foot and a half and about 3.5” apart. Then I bought some top rails for a chain link fence for the poles. I mounted a wider pole to a 2x4 with a bunch of conduit clamps and some of those (I forget what they’re called) metal tie wraps that you basically screw tight, then a smaller diameter pole to that one (stuck it inside the wider one about two feet and drilled a hole through both poles to bolt them together real well). I then added a slightly wider short pole over all of that and bolted that too for added support. I repeated that with another 10’ pole at the top.
After that, I mounted the anemometer to the top of it with the wire wrapped around the pole going down to connect to the station.
Then I added another 2x4 to the opposite side of the bottom part to sandwich the bottom part between two 2x4’s and then used four more metal tie wrap things to secure that contraption tightly together to prevent the pole from ever falling through the sides of the 2x4’s in high winds.
Finally, I secured the pole (and 2x4 set up) to between the two 4x4’s via a heavy duty hinge at the bottom so I can just lay the whole thing down to access the anemometer) and raised it all up. One up, I screwed it into the 4x4’s at angles with 4” screws. When it’s time to access it, I just unscrew and lay it down. It didn’t budge during hurricane Ida.
Hopefully this all makes sense. In total it’s only about 22’ high when it should be 33’ high but I was afraid of going higher and making it too top heavy. The station itself is mounted to all of this at almost 6’ above the ground for accurate temperature readings.

NOAA NWS Slidell Update:
Area Forecast Discussion
National Weather Service New Orleans LA
1026 AM CST Thu Jan 20 2022
.MORNING UPDATE...Minor updates to temperature, POP, and weather grids were made this morning based on both current temperatures trends and higher confidence that some moisture will be available to produce light wintry precipitation over portions of the area
tonight into early tomorrow morning.
Temperatures have been trending a few degrees cooler than previously forecast behind the cold front, and were adjusted down on the order of 2 to 3 degrees for the afternoon hours. No changes
were made to the overnight lows at this time, but there are concerns we could be a bit too warm for the overnight lows.
Deterministic forecasts are running on the high side of the ensemble spread, so there is the potential for temperatures to be a 2 to 3 degrees cooler than what is currently forecast. Will continue to monitor these trends as additional guidance comes in,
and a lower overnight low may be in order with the full afternoon package.
Additionally, model sounding analysis indicates a deeper pool of avialable moisture than previous runs had indicated, and no significant changes to POP were made. Another supporting factor is satellite imagery continues showing strong moisture transport into
the area on the back of a deep layer southwest flow regime. The slightly cooler temperatures and deeper cold pool have resulted in a slight change in thinking in terms of precipitation type. The cold pool could be as deep as 2500 feet along and north of I-12, and now have more sleet than freezing rain in the forecast for this area. Accumulations are still projected to be light at generally 0.05 inches or less, and the primary impact will remainelevated roadways and bridges. PG

I think they will monitor the situation, and make a final decision tonight or the EBR tomorrow morning around 0530.......

my HOA would get pissed if i mounted something that high
i don't have a huge property either to keep it far away from obstacles
i wish i could mount one of the RM Young anemometers way up though

Supposed to drive from NOLA to Lafayette tomorrow afternoon. I suppose it’s gonna be a game time decision.

Hopefully we warm up enough so that travel after mid morning won’t be affected
Posted on 1/20/22 at 11:14 am to DVinBR
Yeah, almost too big a change considering everything else shows at most very little, patchy accumulation. To go from nearly nothing to over a 1/4" in that large an area has me skeptical.

Dang looks like nothing now for the Houston crew

I’m designing my Starlink internet setup for (hopefully) later this year—planning to use two DirecTV non-penetrating sleds hinged together, weighted, and laid over the peak of my 2nd floor roof. That’ll get me close to 30 feet up, and I’d be probably 300 feet from the closest trees. Thinking I could go ahead and do a weather station setup while I’m at it.
it’s only about 22’ high when it should be 33’ high

That's what the usually do with cold weather. They are generally more proactive with hurricances.

I think it’s supposed to technically be 10x father away from the nearest structure or tree than it’s height. That’s damn near impossible in most settings. Unfortunately mine is surrounded by trees about 75’ away on three sides so my wind is never accurate since it is almost always blocked a little bit. That’s another reason why I’m convinced I had 110mph+ gusts for Ida because it stopped reading at 75mph, and that was with it being blocked from the strongest wind AND an hour before the hardest gusts. Lots of tree debris was flying through the air and hit the anemometer.

By the way, I’m now at 41 degrees. That’s where I was supposed to be at 5:00 this evening. The cold is hauling arse into the area wayyy faster than expected. Surely it’s going to start holding steady soon.

It’s 39 in Baton Rouge and that was supposed to be at 6pm

Uhhh I feel like this is shaping up to be one of those unexpected disasters that we brushed off for days
