A January observation - the lawn is quickly turning green and there is actual growth now.

 

I considered cutting mine the other week but decided that would be too depressing. 

CCR - Bad Moon Rising 

A little under 2.5” here in Exton. 
 
Hopefully we’ll be measuring snow next weekend. 

Up to 30 in Exton. A solid coating of ice on top of 1.7” of snow/sleet. 

1.7” in Exton. 

.8” here in Exton with moderate snow currently. 

Wind has arrived in Exton. Just had a gust to 34. 

.8 in Exton. 

Snow has begun to stick now. Temp is down to 34 with moderate snow. We wasted .01 on white rain here. 

Light snow in Exton, 38°

This would make me sick.

Happy New Year to all!

Another year in the books - let's see how we did climate wise

Paul, I feel like you are the best person to ask. You average 3’ of snow at over 600’ asl. Any idea how locations even higher in the county do? Wondering if places over 900’ like by honey brook and up towards French creek state park average 40 or more. 

Some very light snow coming down in Exton. Temp 34 

A decent snow shower just wrapping up here in Exton. Current temp is 32.

no, observed ice acurral is probably not a great way to calibrate an air temperature thermometer. If the surface is residually cold (meaning colder than the air temperature), the rain will freeze when lands on the colder than air surface. There are better ways to calibrate.   

I agree it’s not the best way. But in the instance of last night there shouldn’t have been residual cold on the surfaces as it had been above freezing during the day. So I’m wondering if it’s possible that surfaces a little lower than 2m could have been just a little colder? Don’t know if evaporation would have that affect. 

Is anybody planning on recalibrating their thermometer based off their observations from last night? I observed  zr at 32.4. Maybe the surface temps were a bit cooler than 2m?

Temperature has continued to fall across NW Chester County this evening now down to the low for the day at 32.1 (I have 2 other thermometers down to 30.0 and 31.1) we have a nice glaze on the deck and ZR continues to fall steadily here in East Nantmeal Township

Different elevations or are they set up at different heights above the ground?

Little bit of a glaze on some surfaces now. Temp holding at 32. 

Just a few tenths of a degree above freezing here in Exton with the dp still around 30. We’ll see. 

Qbo argues for a -nao winter and the Alaska warm pool argues for a western North American ridge. It would be nice if we get extended periods of the two working in tandem but hopefully at the very least if we lose either the pac or the atl the other side will prevent a full on extended torch. 

1” in Exton measured on the board this morning. There was visibly less snow just a stones throw south of here closer to rt 30. That small elevation change has done wonders around here at times. 

40 and light rain in Exton.

Should be an interesting day. Just started snowing in Exton. Temp 34

I was wrong, today was very uninteresting around these parts. It did snow lightly for much of the day though occasionally mixing in with or briefly changing to drizzle.
