Going to eastern Westchester, inroads on the Bronx. That sea breeze shunted it to a crawls pace in areas further south. Cold air funneling down the LI sound makes sense given the ENE flow. It's visible now on TJFK.

Winds suddenly started gusting from the ENE in the Bx while headed east on Pelham Pkwy. A strong cool salty smelling wind. Like a light switch.

It looks like a shower coming in..Unless that's the pollen?

It's coming!

Southern Westchester NY-Bronx NY-New York (Manhattan) NY-
Northern Nassau NY-Northern Westchester NY-
753 PM EDT Tue May 31 2022

...A COLD FRONT WITH GUSTY WINDS AND RAPIDLY FALLING TEMPERATURES
WILL MOVE ACROSS THE NORTH SHORE OF LONG ISLAND AND FAR WESTERN
CONNECTICUT INTO ADJACENT PARTS OF NEW YORK CITY, THE LOWER HUDSON
VALLEY, AND PARTS OF NORTHEAST NEW JERSEY THROUGH 915 PM EDT...

At 741 PM EDT, Doppler radar was tracking a frontal boundary along a
line extending from a line extending from near Danbury to near
Harrison to City Island to Sands Point to Oyster Bay. Movement was
southwest at 15 mph.

HAZARD...Rapidly falling temperatures and winds up to 30 mph closer
         to the coastline.

SOURCE...Surface observations and radar indicated.

IMPACT...Much cooler air, with temperatures rapidly falling through
         the 70s into the 60s after late day temperatures still in
         the upper 80s and  lower 90s.

Scary! No mention of Flash freeze though

May came to a close with a blaze of heat. Near record and record temperatures were registered across the region. Highs included:

Allentown: 92°
Atlantic City: 95°
Baltimore: 96°
Bridgeport: 94° (old record: 91°, 1987 and 2013)
Harrisburg: 92°
Islip: 93° (old record: 92°, 1987)
New Haven: 95° (old record: 87°, 2013) ***New May Record***
New York City-JFK: 94° (old record: 92°, 1988)
New York City-LGA: 93°
New York City-NYC: 93°
Newark: 98° (old record: 96°, 1987)
Philadelphia: 96°
Poughkeepsie: 93°
Scranton: 92° (old record: 91°, 1939 and 2011)
Westhampton: 93° (old record: 86°, 2013)
White Plains: 92° (old record: 90°, 1987 and 2013)
Washington, DC: 96°

New York City will finish May with a mean temperature of 64.0°, which is 0.8° above normal.

The heat was coming to an abrupt end as a backdoor cold front sliced southwestward. In the wake of the frontal passage, tomorrow will be noticeably cooler. However, much above normal temperatures will likely persist from Philadelphia southward in the Middle Atlantic region through the middle of the week.

Galveston is concluding May with monthly mean temperature of 83.0°. That easily breaks the record of 80.4°, which was set in 2018. During May, Galveston recorded 9 90° high temperatures (old record: 4 days, 2011) and 11 80° low temperatures (old record: 4 days, 1996).

The first week of June will likely see near seasonable temperatures. Overall, the month will likely wind up warmer than normal.

The ECMWF seasonal forecast indicates that the summer will be warmer than normal throughout the region and across much of North America.

The ENSO Region 1+2 anomaly was -1.1°C and the Region 3.4 anomaly was -1.0°C for the week centered around May 25. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.55°C and the ENSO Region 3.4 anomaly has averaged -1.08°C. La Niña conditions will likely persist through the summer.

The SOI was +16.10 today.

The preliminary Arctic Oscillation (AO) was -2.281 today. That edges the daily record low of -2.216 from 2016.

On May 29 the MJO was in Phase 6 at an amplitude of 1.909 (RMM). The May 28-adjusted amplitude was 1.384 (RMM).
