I'm halfway up my hill, but on the one flat portion of it. So all of the water seems to drain down 200-300ft to my area and just pools here before it drops off another 200ft toward the river just beyond my house. When I did my chicken run in 2017 we had a stretch of no rain for like 10 days and when I used the post hole digger the holes immediately filled with water right to near the top. It sucks. Maybe there's some clay too, but it doesn't seem that excessive compared to other places I've been. -
Hope the euro is right in keeping most of the QPF south of here. We just can't dry out. I have water bugs swimming around in the backyard where the huge puddles never disappear.

He'll still be finding models in May that show a little blue pixel over NYC.

1.14” rain. Now we attempt to dry out again. Chilly week, but at least with sun we’ll be near 50° despite nights in the 20s.

A little update on the BOS MADIS... I wanna know what they did. That's a 3-4F jump cooler.
-
I'll take the under.

1. Precip blocked by mountains 2. Beam too high to detect precip

Nice job Evan. Randolph on the board.

Weak

Make sure your phone is sideways and click that icon I have selected in the top left. Then click the radar and drag out from the location.

TAN 53mph...not bad for them.

Sliding east of PVD now. 120mph for the bald eagles.

Must suck to get meh wind, but lose power because of wind around you.
-
Boire Field Emphasis on the bore.
-
100kt winds there at about 1500’.

Impressive. Still moving into SE MA.

I got a rock.

The drop in voltage only affects the maximum possible recordable wind speed. IIRC, the max is around 175mph at 150ft but drops to under 140mph at about 250ft. They have large and small wind cups too which have different accuracies and max capabilities at different speeds and cable lengths. Just found this... https://www.novalynx.com/manuals/WRM_apnote15.pdf Most of the Davis stations now have an integrated sensor suite or wireless anemometer transmitter so lengths are generally 40ft or less.

It’s tough to get a near instantaneous mechanical sensor since you need to get a specific number of revolutions per given time to determine a speed. There’s just not enough rev samples if you try to cut it down to under a second. Now they could be using a 3rd party ultrasonic sensor that would have instantaneous capability, but my assumption was that they had the cups. Here’s Davis’ speed equation calculation...
-
I’ll add that the Davis is NOT instantaneous. It’s actually a 2.25 second average. There’s a magnetic reed switch that measures the amount of revolutions per the given time.
-
There you have it. Time to retire that one or calibrate it. lol

http://bluehill.org/observatory/2013/01/current-conditions/ Looks like the strongest their Davis has recorded back to 2004.
-
76mph on the MQE Davis.

Later this afternoon for you guys.
