Rain to snow changeover work better than phase jobs. If there is rain then generally the cold air push is not strong enough to suppress nor run it due East
Looking at temps and precip this month the years 1955,1975,1980,1984, 2017 match up. I don’t do pre DCA. This is before the showers tonight .
All of the January’s were cold and couple very cold. Hope is alive
Main thing DC always has to stay away from is never ending 1-2 week push backs. Once that starts it rarely stopped. Couple weeks ago looked like 12/27ish might start a change so let’s hope first several days of Jan do because once we start the 1/8, no 1/18 then we are most usually SOL. Feb 2007 an exception but far from the rule
Really
This Again?-pattern change just a month away. Probably the most over stated yet under occurrent statement that gets made here, along with the 360 GFS always showing a big winter event
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.
