WEATHER53

Utterly correct non agenda fact backed observation and exactly how it is Most of the Time as opposed to last nights exception. Is BWI generally 5-10 degrees warmer than Glen Burnie? We know the answer

Last night had a range of 27-31 fir the suburbs. Andrews being merely 2 degrees colder is very rare and you all know that. in all honesty there is nothing for me to discuss with newcomers or those who have not closely monitored this irregularity for 40 years and are wedded to heat island. I noted about 5 other city stations along the east coast. Show me that they are always 5-10 degrees warmer than 1-10 miles away and I will shut up . if we get a chance like we do about once every 7 years Please watch DCA during an intense area wide snowstorm. 4” on ground everywhere, snowing moderately, DCA 29 and all others 24/25. I’ve seen that about 6 times. Where’s the heat island when blanketed in snow and snowing moderately or heavier?? kinda being told my eyes are deceiving me so rejecting that as I have for decades.

Doug Hill has died Great guy. Always kind and thankful for obs and discussion

Did avoid another gross inaccuracy overnight and hit 32 for first time even with all surroundings 5-10 colder. I have no idea how to do it AND I would shut my mouth forever should the following occur. -Take Logan, La Guardia, Philadelphia, Baltimore, Richmond and Miami. Do those stations consistently read 5-10 degrees warmer than what is within 1-10 miles of them. I already know the answer for Baltimore is NO proof would be in that pudding. Heat island comment is a default dismissive attempt to look no further. If DCAs sensors are, for example, out on a overgrown former parking lot or located very close to the office to allow easy access then that could be an issue. Otherwise it’s kinda down to that the buildings to the west are leaking tremendous warmth because NSE is mostly parkway open space and water. So, where’s the heat? Downtown DC, NYC, surrounded on 4 sides-that’s a heat producer. And, same thing happens when Potomac is frozen even if less dramatic on order if 3-5 and not 5-10

5 am ob should do it maybe 4 Where is the spreadsheet?

DCA madness again last night Everyone else 24-27 DCA 33 Eveyone else dropping hour by hour until dawn DCA 33 for hours. Wherever those sensors are is a location prohibitive to accuracy for the area the station is designated to represent The thermos are reading correctly for wherever they are, it’s wherever they are thats the problem and produces the skewed and non representative reports. Freedom plaza or the Willard are all asphalt buildings and. concrete. That’s a heat island. DCA has buildings to the west and remainder water or open space. And , when Potomac is frozen or very cold, this still happens.

DCA tried really hard even with south component RIC did make it and I think I had like 11/13 for both,

DCA won’t radiate out overnight to 32 but if winds can stay 10mph thru sunrise Sunday it will hit 32

Talking to my brother In law who moved to Thurmont last year. He talked about an Old Mink Farm place that he says is like 1,600’ elevation. Last night said it was 27 by midnight and high for the day was 48. I did not think those mountains were that high? Anyone else familiar?

38.5 at midnight, coldest of season

42.8 at midnight coldest for time this season High dews and this could play out some frost at 35 or we start to dry out and temps and dews drop in tandem to 30 BWI and IAD

45.5 midnight so lowest at time for season

Easily coldest this time(11pm) for season with 46 at 11pm eclipsing previous 49

Get the drought hypers to contribute

1991 was huge and then it was 92/93 for another then Isabel then 2011 as far as big fetch driven flood events I can remember.

Wow. Some high tides up to 5’ above ground level along western bay areas!

As winter seasons roll on I have become in agreement with something I wasn’t.-“ Don’t waste the cold” DC gets. back to back bellow average months once a year and when that’s DJF it’s gold. Since mid 60s DC gets a big winter about every 5/6 winters and every 6 years the two month cold hits at the right time for us. Mid Oct thru Mid Dec cold is useless. Let Pac roar now and not later

Two 38 mph gusts in last 10 minutes

Steady moderate to heavy rain for 3 hours. 1.32”

48 at midnight which is coldest at time for season

Blew thru here at 2:10 , 35mph gust, 2 minute deluge, 0.12” total, 10 degree temp drop

Rotating east to west rains look to be closer to DC than forecasted yesterday

DCA: 11/13 IAD: 10/17 BWI:11/12 RIC: 11/13 Bwi:0.79”

Got a lot of play as a rogue bolt.
