Feels refreshing, but yet another overcast/rainy day to mark down. Lets see if can clear out before sunset. Was P. Sunny this morning.

Yup. Nice catch as I close the doors & windows now. Went from 60s to 50s.

My Backyard 68° to 58°


Danbury, CT 63° to 57°
NYC 65° to 55°
White Plains, NY 63° to 56°
Bridgeport 71° now 69° rain hasn't gotten there yet


Feels like October! 50s at 2pm??? I didn't expect this actually.

I notice that happens whenever dew points are noticeably lower than the air temperature when it's raining. Is the rain cooling the air off to the dew point?

It cooled the air but dew point rose a bit into low 50s to meet up. Dews should start dropping again after the rain passes NYC. Wonder how low. I assume low 40s tonight?

Nice! wow!

Looks like it may even dropped a hair under 40? 2:35pm reading has 39. Looks fishy though. I love how IEM now has OBS every 5 minutes. Sucks to scroll through them for the day but very cool to see the in between hourly data

NYC

Ah, so basically it's making the RH closer to 100%?

just went to my local park and it was 20c with 90% RH. So basically the dp is at summer level from now on. Felt cool / muggy, the usual combo.
