The Arctic experienced a record May and June combination of warmth and high pressure. So we have been seeing steep declines this week even with more favorable conditions than the last few months.

Weather history is currently being made. This is the first time that the dewpoint was 79 degrees at JFK at 6am. We also set the overnight record for highest dewpoints. Notice how many new hourly records were set in recent times. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=153&network=NY_ASOS&zstation=JFK&month=all&var=max_dwpf&dpi=100&_fmt=png

Last winter the interior beat the coast. Cutters and huggers favored those areas with the absent BM tracks.

You might be onto something if this raging Pacific Jet doesn’t subside.

Newburgh has the highest official regional station dewpoint at 81 degrees. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KSWF

You know the sensor is really blocked beneath the vegetation when the average high this month through the 18th is the same as ISP and JFK. NYC...86.6 EWR...88.8 JFK.....86.6 LGA....88.5 ISP......86.7

Dewpoint reached 80 degrees in MSP. Their highest on record is 82. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KMSP https://mobile.twitter.com/NWSTwinCities/status/1152311608166768641 The dew point is up to 80° at Minneapolis-St. Paul International Airport as of 3 PM. Highest dew point in the Twin Cities since 2011, and just 2 degrees below the highest dew point on record.

Yeah, the firehose Pacific kept pumping the WAR. Cutters and huggers dominated with the fast flow. Kept things wet but not white.

Another big daily drop of 187K puts 2019 into 1st place on 7-19 for NSIDC extent. The early portion of August is when 2012 ran away with the lead during the record Arctic storm. ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/seaice_analysis/Sea_Ice_Index_Daily_Extent_G02135_v3.0.xlsx 7-18-19....7.267 7-18-11....7.299 7-18-12....7.420 A few papers on the record breaking 2012 season: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/grl.5034 On the 2012 record low Arctic sea ice cover: Combined impact of preconditioning and an August storm https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/grl.50190 The impact of an intense summer cyclone on 2012 Arctic sea ice retreat

This continues to be the year of the record breaking firehose Pacific Jet. The Pacific Northwest just established an all-time strongest jet stream for the entire warm season. This old record was beaten by a wide margin. It’s pumping the ridge over our area for high heat and humidity this weekend. https://mobile.twitter.com/SimonLeeWx/status/1151959134545358849

SST’s warming quickly now with 80 degrees just east of Barnegat, NJ.

It has a regional dewpoint max of 81 on Saturday and 80 on Sunday.

12z Euro has 80 degree dewpoints and 23C 850 MB temperatures both Saturday and Sunday.

Continuing to see steep losses even with more a reverse dipole relative to the last few months. That tells you something about the current condition of the ice pack. NSIDC had a -164 K daily extent drop on July 17th. So very close to 2011 and 2012 on this date. Area losses continue to keep pace with 2012. ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/seaice_analysis/Sea_Ice_Index_Daily_Extent_G02135_v3.0.xlsx 7-17-19.....7.454 7-17-12.....7.481 7-17-11.....7.444 Last 5 days
