WEATHER53

Is there a tally sheet with the totals for everyone?

BWI 14.7 DCA 12.5 IAD 15.2 RiC. 9.0 Tie break SbY 9.0

I think we are In the favorable two months mostly below average trait DC displays. Not April May or Sept Oct this time. So we got from now until about 1/1/22-1/15 . These lows just wanna go west with some serious cold coming in behind but the miler Bs just don’t work here. 12.5” DCA seems right

Andrews23 DCA 30 and Andrews is further East and south and in a similar situation of marginal “heat island” influences of being surrounded by improved property. Andrews really is the killer of all OK at DCA.

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
