[bluewave]

The historic measurable rainfall streak gets extended to 18 days at Islip. This would even make the top 10 for a place like Seattle.

missed the rains here-the line did the 7-10 split here which I am not complaining about...

I got a bunch of rain here, 5 miles south got nothing but from central Westchester down it was very wet.

Picked up .53" last night with the evening storms

Good to see sunny and 60’s here ahead of the next backdoor for tonight and tomorrow. Strong backdoor temperature departure signature for the first week of May in NYC. Milder minimums and cooler highs. 

NYC...max departure...-1.4......min.....+0.6

Another nice day out there.

Current temp 70

And notice in Seattle it's a list full of Fall/Winter months. This is absurd/crappy weather

Tough to break out of this soupy pattern with such a big -NAO/-AO drop. EPS hinting at a closed low potential in about 5 days. So we’ll just have to make the most of these sunnier intervals like today.

High 72 here..warmest of the week.

Pattern will likely turn even cooler relative to normal than the first 10 days of May with averages now being in the 70s.

Keep that front form reaching the area until after midnight so we can break the consecutive days streak. It also makes me wonder if the warmer minimums will be enough to keep the above average temp streak intact. Cooler max's would have to be significantly so for it to change that up.

Today's weather is what I want it to be like EVERY DAY (outside of winter).  Finally I can breathe and no more mold allergies!  Low humidity, clear skies and NO RAIN!  When we finally get weather control I hope whomever controls it makes it like this EVERY DAY!

My garden loves it too- if it needs water, I have a hose (or two) for that!  If it never rains again until next fall I wont miss it one bit, this is PERFECT WEATHER!

I wish we could get rid of these -NAO/-AO patterns during the warm season forever (see my above post.)

Yes but if it doesn't rain it can't wash the pollen out of the air and your allergies will blossom into an uncomfortable mess. You'd also run out of the stuff that comes out of those hoses.

Thats the thing I find confusing.  My allergies dont start acting up unless the humidity goes up.  It's worst when we have cloudy weather with high humidity and it doesn't rain or just drizzles.  Once it rains it gets better but if it stays humid after it's finished raining the allergies come right back.  Sometimes they get so bad I get dizzy, cant hear or see properly and pass out.  That only happens when it's really humid and cloudy during the summer (something like 80 degrees and cloudy and 100% humidity.)

This only really started getting really bad in the last couple of years.  Before that I only took Benadryl once or twice a year and had to throw away expired pills on a regular basis.  Now I have to take Benadryl twice a week for 4-6 weeks during the pollen season.

Bob Henson has a great write-up on the record wet pattern.

https://www.wunderground.com/cat6/Wettest-12-Months-US-History?cm_ven=cat6-widget

The 12 months ending in April 2019 were the wettest year-long period in U.S. records going back to 1895, according to the monthly U.S. climate summary issued Wednesday by the NOAA National Centers for Environmental Information. Averaged across the contiguous U.S., the total of 36.20” made the period from May 2018 to April 2019 the first year-long span ever to top 36”. The old record for any 12-month period was 35.78”, from April 2015 to March 2016.

...its gotta change..and when it does we will be in for some nice, warm days..today was nice but 

once the whole pattern changes we are still stuck.

betcha bottom dollar memorial day will feature some sunny days with warm temps..that would

be some nice beach days to start the season..just don't go in the water!!

Today had absolutely perfect early May weather.  I mean what a day.  Sunny, warm, dry, and blue skies.

[Cfa]

It’d be nice if we could have multiple weeks of today’s weather, but instead we’re stuck in an oceanic hellhole.

Next 8 days averaging 59degs., or 2degs. BN.

This May -NAO pattern really means business. Heaviest May daily snowfall for Duluth Minnesota on record. Also a possible new warm record in Greenland for this time of year.

Code Red for #Greenland. Possible new April record high for the DMI station 04416 at Summit (the top of the Greenland Icecap). However needs to pass quality control made by DMI climatologist before being official, but NOAA station close by also warm. Old record was -6,5°C

Another morning with heat on.

 

This warm/wet spring has come with plenty of cold mornings and cool windy days

[CIK62]

GFS has decent weekend, with just a trace of rain during daylight period.    Problems for Monday.    But SREF Plumes do have rain on Sunday AM.

The whole period through Sunday has been trending drier. Some showers tomorrow night and that's about it

Euro is a washout for Sunday.  Nam (out of range) has rain Sunday AM as well...

They'll trend wetter as we go forward. Focus could be on Sunday night through Tuesday. 

Models slowing down the systems given blocking. Nasty early week with highs only in the low to mid 50s (or colder given coastal signal) with rain.
