March 2016 Forecasts, Disco


snowman19

Recommended Posts

Euro all out torch next week including the weekend. No back door either for sne

 

It has a record high forecast temperature for NYC on March 9th of 71 degrees. Maybe we can tack

on a few more degrees with the way these warm days have been exceeding guidance lately.

 

March 9th NYC current top three warmest:

3/9

69 in 2000

66 in 1977

66 in 1921

Much different story when it comes to over performing on temps that warm, any flow that isn't west will not be enough this time of year

The next 7 days look rather mundane with temps well above average. The overnight ensemble package from both the GEFS and the EPS begin to breakdown the SE ridge putting us into a great pattern for stormy weather. The LLJ should position itself to crank from the Southern plains up the Apps and right into our region.

Very active pattern setting up if the Southeast ridge relaxes just enough to keep the boundary overhead.

 

 

Seasonal pattern says that boundary will end up further north initially than is being shown by the GFS.

We may have to be patient for that SW cutoff low to get ejected NE to our region. EPS were

slower with the the ejection but the rains eventually got here.

It starts off further North which is why we get that warm push mid-week. The GFS just starts dropping it South quicker.

The other models have more respect for the WAR so it takes longer for the boundary and the rains to 

get in here. But that SW cutoff and rains eventually kick east just slower than the GFS has.

The 12z GEFS mean is a bit slower than the op.

The operational GFS is notorious for speeding things up way too much and real bad busts especially during changes of season, in this case, wavelengths shortening, going into spring. It also tends to be way too cold in the long range and digs for gold with troughs, storms and fronts

It's brutal in the summer with FROPAs, it'll show 5 days out a cold front crossing on Friday and it ends up coming across Saturday night or Sunday

Euro has more respect for the WAR this week and keeps the warm up going into

Thursday before the backdoor arrives on Friday.

 

Euro highs for NYC:

 

Tuesday...........67

Wednesday......73.....new record

Thursday..........73

 

The WAR maxing out near 579 DM close to NYC is approaching the strongest ever this early in March.

Do you have the equivalent chart for the 850mb Soundings at OKX?  Could you post if you do.   Thanks.

Gonna need 12C for the low 70's I think at this time of year.   GEFS stops just about at 10C for the mean on Wed.

I assume the time frame starts with 1950 since upper air data sparse before that.

NYC reached 71 on March 8th, 2012 with the 850's remaining below 10C.

NYC made it to 85 on 3/13/90 with 850's in the 12-13C range. The lower levels 

in 1990 were really warm with more of a SW to W flow.

Spring will be in full bloom by Wednesday with many areas especially away from

the water seeing their first 70's of the season. This continues the extreme contrasts

between warm and snow this winter since it's less than a week after it snowed here.
