mitchnick Posted January 4, 2014 Share Posted January 4, 2014 6.2 for my low. Looks like the big three will come in with lows of: BWI: 7 IAD: 9 DCA: A balmy 17 Looking ahead to Monday/Tuesday....I don't think I've ever seen wind chill watches hoisted before. Western MD, parts of WV and Western PA have them for WCs in the -20 to -40 range. And after today's high, International Falls will not reach 0 again until sometime on Thursday. Would love to just spend one winter up there. at 6:54 BWI shows the minimum temp for the last 6 hours was 6 degrees it wasn't an hourly reading so it must have come in between but will still be recorded as the low of the morning http://www.nws.noaa.gov/data/obhistory/KBWI.html Link to comment Share on other sites More sharing options...

attml Posted January 4, 2014 Share Posted January 4, 2014 It was down to 15.8 in Round Bay/ Severna Park this morning. The river water temps in the 30's is helping keep our overall temps elevated a little bit. Not suprising - many mornings on the way to work it can be as much as a 5 degree difference in temps 4 miles away as I move away from the river! What are everyones thoughts on tomorrows predicted icy system? Doesn't have it's own thread at the moment? Mark Link to comment Share on other sites More sharing options...

Kay Posted January 4, 2014 Share Posted January 4, 2014 Low of 4. You can't see it that well in this pic but the river is iced over all the way across. Link to comment Share on other sites More sharing options...
Bob Chill Posted January 4, 2014 Share Posted January 4, 2014 Nice pic Kay. My parents were big boaters when I was a kid. I grew up on the bay on the weekends. Some of my fondest memories were the big freezes in the 70's. I remember people driving pickups across the upper end of the west river and ice boaters doing 60 with howling nw winds. Not sure we'll ever see that again but your pic brings back memories Link to comment Share on other sites More sharing options...

Not sure we'll ever see that again but your pic brings back memories Kay's picture reminds me of a ridiculously cold Sunday in February, 1979, when my sister and I were ice skating on St. Leonard's Creek down past Wes's current location in southern Calvert county. Late that afternoon the snow began that was expected to bring 1 - 3" but didn't end until noon the next day, President's Day. Link to comment Share on other sites More sharing options...

I've seen it freeze over here at least briefly or partially many times, but only rarely to the point where people bring out the ice boats, and never the pickups! My family didn't do boating/bay stuff, and I moved out here after years in Balto. City...so have to make the memories as an adult. It's a great way to grow up around here.

das Posted January 4, 2014 Share Posted January 4, 2014 6.8F was the low last night at 4am in Clarksburg . Pretty chilly. Low for the day yesterday was the 8:15am reading of 9.8F. At midnight, the temp was still 11.6F. Temps did not really drop that last 5F until winds went completely calm starting at 2am. Link to comment Share on other sites More sharing options...

WEATHER53 Posted January 4, 2014 Share Posted January 4, 2014 Are the weatherbugs that reported 15/16/17/18* lows located properly? Roof tops and balconies and really anything surrounded Solely by macadam, building, concrete are going to radiate warmth which produces artifically high values.

Roof tops and balconies and really anything surrounded Solely by macadam, building, concrete are going to radiate warmth which produces artifically high values.From what I understand the temps are not raw but get run thru a proprietary algorithm to 'guess' the standard level temp since most are on rooftops etc. I would think in a lot of cases you're colder on a rooftop than street level in the city anyway. Considering we were pushing above 0c at 850 by mid evening the cold performed pretty well. UHI is very real unfortunately. Link to comment Share on other sites More sharing options...

Roof tops and balconies and really anything surrounded Solely by macadam, building, concrete are going to radiate warmth which produces artifically high values. there are PWS's that are sited lower/on the ground, which corroborate weatherbug's.....I'm all for moving the station from DCA....but having lived in DC proper for 15 years now, you are not going to get anything substantially different moving it into DC, unless you go up near Tenleytown or Friendship heights...I lived within spitting distance of the zoo for 8 years, and UHI is significant there.....I kind of like Andrews for an official station...they seem to be less susceptible to UHI, though they still occasionally share DCA's microclimate....I think we can all agree, DCA is the absolute worst place to have an official station Link to comment Share on other sites More sharing options...

Not sure why we always end up having these conversations. If you want a big snow total or a super cold low it's obviously not the place to go but it's still valuable. There are a ton of official locations that suck. The only great answer is probably to double or triple them .. but I guess PWS/wxbug etc are filling in the holes.

I have a big enough sample to know I average 125% of DCA's snow.....and it is very very consistent...most I have ever received is 142% of DCA's total dating back to 98-99...so you are only going to get a slight bump in snow given the paltry amounts we often get....temps will be the same, as I also get the insane 77 degree mins in the summer....so in the end, DCA isn't representative of the burbs, but is for the city Link to comment Share on other sites More sharing options...
