A-L-E-X Posted February 1, 2011 Share Posted February 1, 2011 Yup, Im right--- Mt Sinai and Miller Place are both around 23.4 and 23.5 degrees; even Bridgeport is at 23F and I find places on the North Shore of LI mimick the South Shore of CT.

Hailstorm Posted February 1, 2011 Share Posted February 1, 2011 Of course not every part of NYC is high urbanized I mean SI/Eastern Queens/Parts of NW Bronx(Riverdale) and areas like Throgs Neck are certainly more like the burbs then Urban. I've been in the burb part of the city during a freezing rain event and it isn't pretty on the sidewalks... I agree; southern Brooklyn isn't as urbanized as Manhattan either. In addition, with temps in the mid-20s that may drop some more overnight, it would help mitigate the effects of any urbanization heat island effect as opposed to having temps in the 30-32* F degree range.

A-L-E-X Posted February 1, 2011 Share Posted February 1, 2011 Not yet, but cold spring harbor reporting a temp of 22.4, 25.2 in northport, and i did have a high of around 32 degrees earlier today which was consistent at the time with other reports. I will try calibrating it in a little while with the ice water method. Miller Place and Mt Sinai would agree with you. Where did you get the Cold Spring Harbor temp? Theyre not on the north shore and arent usually one of the colder spots on the Island-- despite its name Link to comment Share on other sites More sharing options...
jconsor Posted February 1, 2011 Share Posted February 1, 2011 That WeatherBug station in Cold Spring Harbor is running a good 2-3F too cold - I wouldn't use it for any comparison purposes.

IsentropicLift Posted February 1, 2011 Share Posted February 1, 2011 Latest from Upton, just as I feared based on the warnings, Upton not buying the warm up as advertised on the NAM/GFS. NEAR TERM /UNTIL 6 PM THIS EVENING/... -- Changed Discussion --PRECIPITATION IS TAPERING OFF...WITH SNOW/SLEET FALLING ACROSS CT AND LIGHT FREEZING DRIZZLE ACROSS MOST OF THE REGION...WITH PLAIN DRIZZLE ACROSS LONG ISLAND...WHICH HAS RISEN ABOVE FREEZING. PARTS OF CT COULD PICK UP AN ADDITIONAL 1 TO 3 INCHES OF SNOW/SLEET ACCUMULATION THROUGH THIS AFTERNOON BEFORE TAPERING OFF LATE. MAX TEMPS ON TRACK TO TOP OFF IN THE MID 20S ACROSS THE INTERIOR AND AROUND 30 ELSEWHERE.-- End Changed Discussion -- && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... -- Changed Discussion --SOME ADJUSTMENTS MADE TO THE FORECAST FOR TONIGHT THROUGH WED MORNING. MODELS INDICATING A BREAK IN THE PRECIP THIS EVENING...SO LOWERED POPS ACROSS THE REGION TO CHANCE THROUGH AROUND MIDNIGHT. AS LOW PRES APPROACHES TONIGHT...PRECIP BEGINS IN EARNEST ONCE AGAIN. WILL INCREASE POPS TO LIKELY...THEN CATEGORICAL...FROM WEST TO EAST AFTER MIDNIGHT. WITH SFC TEMPS GENERALLY IN THE MID 20S ACROSS THE INTERIOR TO THE LOWER 30S ALONG THE COAST...THERMAL PROFILES FROM THE 12Z NAM BUFKIT SOUNDINGS INDICATING A WIDESPREAD FREEZING RAIN EVENT. WILL BUMP UP ICE TOTALS TO AROUND 1/2" FOR THE LOWER HUDSON VALLEY AND INTERIOR PORTIONS OF NE NJ AS WELL AS NORTHERN FAIRFIELD AND NORTHERN NEW HAVEN COUNTIES IN CT...AND WILL CONVERT WINTER STORM WARNING TO ICE STORM WARNING FOR THOSE LOCATIONS. FROM HERE ON OUT...H8 TEMPS WILL WARM TO ANYWHERE FROM +2C TO +4C WHILE SFC TEMPS REMAIN BELOW FREEZING. BY LATE MORNING/EARLY AFTERNOON...PRECIP WILL TURN TO ALL RAIN ALONG THE COAST. TIMING IS UNCERTAIN AT THIS TIME...AS WELL AS PLACEMENT... AS IT APPEARS AS IF THE WARM SFC AIR COULD REACH SOUTHERN CT BY WED AFTERNOON. IF THE COASTAL LOW DEVELOPS A LITTLE FURTHER S THAN CURRENTLY EXPECTED...THEN NYC MIGHT NOT HAVE THE COASTAL FRONT GO THROUGH...AND THUS WOULD NOT CHANGE OVER TO ALL RAIN...AND THE TRANSITION ELSEWHERE WOULD BE DELAYED. PRECIPITATION SLOWLY TAPERS OFF FROM W TO E LATE WEDNESDAY AFTERNOON/WEDNESDAY EVENING AS THE COASTAL LOW PULLS AWAY TO THE NE. THERE IS SOME SUGGESTION THAT THE NORTHERN TIER...ESPECIALLY INTERIOR SRN CT COULD END UP IN THE DEFORMATION AXIS OF THE DEPARTING LOW...WHICH WOULD RESULT IN ACCUMULATING SNOWS ON THE BACKSIDE OF THIS SYSTEM WEDNESDAY NIGHT. THIS IS NOT CONSIDERED LIKELY AT THIS TIME...BUT WILL HAVE TO BE MONITORED. COLD AIR POURS INTO THE LOW LEVELS IN THE WAKE OF THE STORM WEDNESDAY NIGHT...WITH A RAPID FREEZE OF ANY LIQUID ON UNTREATED AND POSSIBLY EVEN TREATED SURFACES. CANADIAN HIGH PRESSURE AND WEAK RIDGING ALOFT BUILDS IN THURSDAY WITH DRY AND COLD CONDITIONS EXPECTED.-- End Changed Discussion -- Link to comment Share on other sites More sharing options...
NorthShoreWx Posted February 1, 2011 Share Posted February 1, 2011 He doesnt know north shore climo I bet places like Miller Place and Mt Sinai are even colder than you-- they are Long Island's cold spots. Really? How did you come to this conclusion? Why are they different from other places on the north shore (or the central parts of the island)?

ag3 Posted February 1, 2011 Share Posted February 1, 2011 Miller Place and Mt Sinai would agree with you. Where did you get the Cold Spring Harbor temp? Theyre not on the north shore and arent usually one of the colder spots on the Island-- despite its name Cold Spring is on the north shore. Its in between Hempstead Harbor and Northport.

jasonli18t Posted February 1, 2011 Share Posted February 1, 2011 Our dots on the map are very close...I'm under the red dot that I drew on this map. It has definitely cooled quickly along the north shore. That cooling may make it down across the entire island over time: Yes it does look like it should spread to most areas on the island with time. I was no expecting it to drop so sharply so early...almost like a cold front passage. Link to comment Share on other sites More sharing options...
jasonli18t Posted February 1, 2011 Share Posted February 1, 2011 Cold Spring Harbor is on the north shore where the county lines on Nassau ands Suffolk meet. It might be inside a bay/inlet but they are still on the north shore. Yes cold spring harbor is very much on the north shore, alex must have been thinking about another town. it even has cold in the name Link to comment Share on other sites More sharing options...

EasternLI Posted February 1, 2011 Share Posted February 1, 2011 Made it up to 33.2 so far today, that was about 20 mins ago....However seems to be going down now...Currently 32.8...Very very light east wind the whole time Link to comment Share on other sites More sharing options...
Dosh Posted February 1, 2011 Share Posted February 1, 2011 Sidewalks are icing up pretty quickly following the temp drop, but streets are still wet and full of puddles. it probably wont be until the nighttime hours that everything freezes up given this thin cloud layer.

A-L-E-X Posted February 1, 2011 Share Posted February 1, 2011 Really? How did you come to this conclusion? Why are they different from other places on the north shore (or the central parts of the island)? You helped lol. I used the snowfall maps on your site and zeroed that area down as being the snowiest part of Long Island. I also looked at the geographical location-- that area has the longest fetch over the Sound so they probably do the best with sound enhancement. Furthermore, checking weather underground PWS data, Mt Sinai and Miller Place always seem to be the coldest during storms. Just like with this one (I posted the map earlier.)

jconsor Posted February 1, 2011 Share Posted February 1, 2011 Both the Mt. Sinai and Miller Place Wunderground stations appear to have about a 3F cold bias.

chazman Posted February 1, 2011 Share Posted February 1, 2011 Fresh Meadows...28.8F and light freezing rain.

A-L-E-X Posted February 1, 2011 Share Posted February 1, 2011 Both the Mt. Sinai and Miller Place Wunderground stations appear to have about a 3F cold bias. Surrounding stations are in the 26-28F range. Do you think that might be the case with two different sensors? Maybe. Usually I find Shoreham right in line with them, but this time its a bit off so you might be right. During most storms, Ive found Miller Place, Mt Sinai and Shoreham to be within a few tenths of each other. What do you think of the idea that this region is the snowiest place on long island, based on location, fetch of northerly winds off the Sound, etc.?

I was no expecting it to drop so sharply so early...almost like a cold front passage. I think it was something like a cold front with the wind shift...maybe a subspecies of coastal front It's now down to 27 here ...which is about where it was during the coldest part of the pre-dawn hours. Not a good thing if someone has been driving since it was 33 and is assuming that the roads can't be icing. Link to comment Share on other sites More sharing options...
meteorjosh Posted February 1, 2011 Share Posted February 1, 2011 Not a ping nor a flake here in midtown (just moderate rain), and oddly enough no accretion even on metal street signs and posts...this rain must be falling through a very warm layer.
