IronTy Posted March 18 Share Posted March 18 Why is this winter so terrible? I'm so tired of cold and gray. Are there any stats showing that the last 6mo have been cloudier than usual? Link to comment Share on other sites More sharing options...
kgottwald Posted March 18 Share Posted March 18 NWS sites used to measure "daily minutes of sunshine" but stopped doing that in 1998 - something to do with the switch to ASOS. Big step backwards. Link to comment Share on other sites More sharing options...

Big step backwards. The MD Mesonet stations has sunshine detectors (pyranometers). We're recording the data and eventually we'll have statistics on it but it fairly low on the priority list. We should be able to do % of sunshine and energy but % of normal will be harder to determine since there isn't a good history. 1 Link to comment Share on other sites More sharing options...

Hoping to get some afternoon sunshine. Link to comment Share on other sites More sharing options...

Are there any stats showing that the last 6mo have been cloudier than usual? Sample size of one, but for my solar array: 12/20/25 - 3/17/26: 1.2 MWh of power produced 12/20/24 - 3/17/25: 1.4 MWh of power produced 12/20/23 - 3/17/24: 1.4 MWh of power produced So, call it a ~15% reduction in power produced due to cloudiness and snow cover between last winter and this winter (and the winter before that too). Feels worse than that though. Link to comment Share on other sites More sharing options...

Feels worse than that though. Very interesting. I didn't think to look at the system output for our rooftop in DC. Either the weather is getting shittier every year since 2022, the sun is dying, or my panels are aging. 1 Link to comment Share on other sites More sharing options...

katabatic Posted March 18 Share Posted March 18 @IronTy that's also what I recorded this morning: 8F for a low. It'll likely be next season before we see single digits again. All in all, a decent winter out here. I'd give it a B. 2 Link to comment Share on other sites More sharing options...

WEATHER53 Posted March 18 Share Posted March 18 Very cold low of 20.5 at Frederick house and 24 in Kemp Mill. Frederick just broke freezing at 1pm and now 32.7 . I remember the storm of the century 1993 we had a high next day of 28 which is coldest high I can remember for mid March Link to comment Share on other sites More sharing options...

Tack on another 10 kWh for the afternoon and call it 340 thru the 18th. Through the 18th last year I was at 496.5kWh. Obviously the end of the month can generate more sweet sweet solar juice, but I am not going to make up that gap. 33% drop Link to comment Share on other sites More sharing options...
TSG Posted March 18 Share Posted March 18 Still haven't hit 40F in Cville despite having full sun since about 9am. This is one of the coldest late March days I can remember 1 Link to comment Share on other sites More sharing options...

I bet that’s the bigger factor than clouds. 1 1 Link to comment Share on other sites More sharing options...

Trees aren't an issue for me as it's a rowhome right downtown. But you're probably on to something regarding snowcover. Last year and this year saw significant stretches of snow on the panels so that probably explains the drop vs. 22/23. Link to comment Share on other sites More sharing options...

CAPE Posted March 18 Share Posted March 18 Looks like 37 will be the high here after a low of 25. Feels quite cold despite the strong mid March sun. This would have felt refreshing a month or so ago. I guess those super warm days effed me up. 1 Link to comment Share on other sites More sharing options...

Sunny af today, though. 1 Link to comment Share on other sites More sharing options...

Definitely cloudier this month compared to last March. Everyone says how bad the clouds are in the great lake region, especially the snowbelts off Ontario. I've been following and comparing it to here. We seem to be as bad or worse. I've seen about 3 sunny days since the cold ended in Feb. Link to comment Share on other sites More sharing options...
