I have a hard time trusting the modeling which shows a trough, -NAO  etc for day 10-15--seen that before-this week for example looked cold and stormy 2 weeks ago and we're going to end up with historic warmth

 

For all the ensembles that go out past days 6-10, many times it doesn't pay to even look at them after day 10.

 

Sometimes we get lucky and aspects of the post D10 forecast work out. Most of the time though, day

6-10 is the effective limit of what ensembles presently can do. This a a big step up from the 70's 80's

when the day 1-5 was often uncertain.

DECEMBER REDUX:

http://www.nws.noaa.gov/cgi-bin/mos/getmex.pl?sta=KACY&sta=KEWR&sta=KNYC&sta=KJFK&sta=KLGA

 

The 8 day period, including today will average +15.   56 versus 41normal.  That is OK for April 25th.

This would mean a record pace by the Ides of March morn of +8.6 for the month.

No below normal day till 3/21 at least.  

 

The latest 12Z GFSx is about +17 for the next 7 days.

Some records that could be threatened in coming days:

 

March 9:

Highest minimum temperature: 48°, 2000

Highest maximum temperature: 69°, 2000

 

March 10:

Highest minimum temperature: 51°, 1955

Highest maximum temperature: 74°, 2006

 

Also, assuming scenarios of MOS +/- 3° for the March 8-14 period and then anomalies of -5° to +5° for the remainder of the month, there would be an implied probability that March would be above normal of approximately 99% and an implied probability of a +3° or higher monthly anomaly of 66%.

beware the sea breeze tomorrow with light southerly flow and march ocean temps

 

I'm at 58 degrees right now. A couple degrees above forecasted.

I don't see an issue getting into the 70s Wed and Thurs.

Tomorrow should get to the mid to upper 60s.

i don't disagree with 60's tomorrow but there will be a dive in temps after about 20z from the city eastward

There's a good reason the NWS doesn't issue forecasts beyond 7 days - extremely high uncertainty that far out with chaotic systems (even deterministic ones).

61 already

Mt Holly forecast highs for me

Tuesday: 73

Wednesday: 76

Thursday: 79

Enjoy everyone

 

I think everyday will bust high for NYC.

Yesterday was supposed to be 55 degrees and NYC metro hit 60-63 degrees.

 

Today is already up to 56-58 degrees.

 

I would add 2-3 degrees to the NWS forecast for NYC metro.

DECEMBER REDUX CONTINUES:

Next 8 days including today, fiqures to be  +17.    58 versus 41.  If correct, this would make the first half of March about +9.3.   ie.  (8x17)+3 = 139/15.   The 3 is the current surplus for the first 7 days.

http://www.nws.noaa.gov/cgi-bin/mos/getmex.pl?sta=KACY&sta=KEWR&sta=KNYC&sta=KJFK&sta=KLGA

 

Notes for rest of month:    3/15-16 near normal       3/18-23 another way above normal period.   Near or below normal right at end of month.    Meanwhile April keeps looking closer to normal to me on the long range.
