WxUSAF Posted October 17 Share Posted October 17 39 minutes ago, TheClimateChanger said: If BWI was running 2-4F warmer [relative to average] than all other sites, you can guarantee, there'd be 100 posts about this at this point. Now, it's crickets - although I do see @WxUSAFhas also raised some questions about the readings recently. Good catch on the humidity and temp. Not a slam dunk, but definitely suspect. The repaving of the apron at BWI seemed to make a real difference a few years ago. Typically pushed BWI temps closer to DCA vs IAD as before. But the min temp readings the last few weeks have surprised me. Link to comment Share on other sites More sharing options...
LongRanger Posted October 17 Share Posted October 17 BWI has been about 5 degrees colder than MBY, and MBY is several hundred feet higher in elevation. Only way I see that actually happening is during calm winds for most/all of the night, which has not been the case lately. Something is goofy with the recent BWI temps.

dailylurker Posted October 17 Share Posted October 17 I use to work for fedex express some years ago. I had to make a early morning run from my station in Crofton. Crofton is about 18 miles south of BWI. I remember a lot of times that I would see frost around the airport but not anywhere else. It seems like it's so open there that it radiates well during the right conditions. I think the temps are probably accurate. One thing that still pisses me off is the slant stick measurement in the 2016 storm. They claimed they had 29" and that beat the Nickerbocker storm. Pffff. No way. If anything, Feb 2010 beat it but they under measured that one. In 2016 I had about 20". No more then 18" at once. It settled during the dry slot. Man... these edibles i made are no joke lol 2 4 Link to comment Share on other sites More sharing options...

Started couple days ago I agree. Don’t know if it’s relocation or other changes. Link to comment Share on other sites More sharing options...

87storms Posted October 18 Share Posted October 18 My coworker got a great image of the comet using night mode on her iphone. Need to find out how to replicate that on my se 2022. I think the moon was also too bright when I went out. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted October 18 Share Posted October 18 Took another supermoon shot tonight, again with the PowerShot SX530 HS. This one was ISO 100, f/8, 1/250, 80x zoom. The edges are better defined in this one I think. Beautiful night out tonight, I've loved this month! 10 1 Link to comment Share on other sites More sharing options...

WxUSAF Posted October 18 Share Posted October 18 Low of only 43 IMBY and 46 now. BWI was down to 37 earlier and 41 now. But there are several PWSs near BWI with temps in the upper 30s currently. 1 Link to comment Share on other sites More sharing options...

midatlanticweather Posted October 18 Share Posted October 18 Wild temp swings due to some wind overnight! 1:28 am winds were calm and temp went to 38 degrees. Breezes picked up and rose the temperature to 48. 8 degrees at 4:23am. Winds have gone calm again and now I am back down to 38 and the temperature continues to drop.

Here's an example at another airport (in NC) from this morning: Based on some surrounding stations, that BWI freeze is probably right. But we're so used to them being wrong, I agree it looks weird.

But it apparently dropped 2F more from there. Not impossible but unusual at least. Link to comment Share on other sites More sharing options...

Terpeast Posted October 18 Share Posted October 18 There was some thick frost on my car roof. So it might have gone even lower than the 38 reported at the nearest pws. Link to comment Share on other sites More sharing options...
MN Transplant Posted October 18 Share Posted October 18 36 minutes ago, WxUSAF said: Hmmm weird Something is allowing BWI to radiate perfectly down to the DP. The RH at IAD was in the 70s and 80s all night until getting into the 90s when the morning low happened. Meanwhile, from 10pm to 2am BWI was flirting or at 100% RH. All else being equal, I'm going to blame the mega-drought. Link to comment Share on other sites More sharing options...

It was definitely dew-y this morning. I'm ready for a return to milder weather. My mom is on the west coast and said they're getting a cooldown which usually means we're getting a warmup.

As much as I kvetch about colder weather this early in the season, I rarely turn the heat on and I kinda like shooting hoops in a hoodie...adds to the vibe. 1 Link to comment Share on other sites More sharing options...
