The last 3 days of May are averaging 53degs.(48/56), or -14.

Month to date is  64.0[+1.2].      May should end at 62.9[-0.3].

GFS goes for the 100's before mid-June, so don't let today's throwback, atavistic 48---worry your little heart.  lol.

48*(87%RH) here at 6am, rain.          50* by Noon.          51* at 3pm.

This was one of the greatest May temperature drops in a week on record. While the site below uses hourly readings, JFK is 46° cooler than the record high of 94° last Saturday. So our record weather swings pattern continues.

The 2.37 so far at ISP is 3rd the heaviest rainstorm for the last week of May. So with the rainfall in the forecast, Long Island is in track for the heaviest last week of May rainfall since 1984. I will also update the May monthly rainfall records as the rainfall totals increase.

Morning thoughts...

Yesterday, New York City’s Central Park measured 1.22” of rain. That broke the daily precipitation record for May 28. The old record was 1.16”, which was set in 1906. More rain lies ahead.

Today will be rainy and unseasonably cool. Numerous areas could set daily record low maximum temperatures. An additional 1.00”-2.00” rainfall is likely through tomorrow. Temperatures will likely top out in the lower and middle 50s in much of the region. Likely high temperatures around the region include:

New York City (Central Park): 53°

Newark: 55°

Philadelphia: 54°

Tomorrow will be mainly cloudy with some additional showers or periods of rain. It will remain unseasonably cool.

Record low maximum temperatures for May 29 for select locations:

Allentown: 58°, 1950

Atlantic City: 56°, 1946

Bridgeport: 58°, 1950

Farmingdale: 59°, 2017

Islip: 58°, 2017

New Haven: 58°, 2017

New York City-JFK: 57°, 1967

New York City-LGA: 58°, 1950

New York City-NYC: 51°, 1884

Newark: 60°, 1940 and 1950

Philadelphia: 56°, 1884

Poughkeepsie: 58°, 1990 and 2017

Scranton: 56°, 1967

Trenton: 57°, 1901

Westhampton: 58°, 2017

White Plains: 58°, 2017

Seems like the Islip area got more rain than much of Long Island. Most areas seem to have between 1-2 inches.

There was lots of flooding around here last night.   It was a scary drive home last night as a lot of areas are pitch black.  I'm still not used to that.

Yea the rain from a few days ago I received only .11 but areas closer to Islip got almost a 1/2 inch.

Good Saturday morning everyone,  Judging from the mesonet reports etc, I suspect a few spots in our NYC forum will reach~ 4" by Monday morning. Cold and nasty but needed. For the record books here and there but main impact no picnics/beaches/causal walks.  Also was aware of the severe wx threat a few days ago but somehow just wasn't too alarmed.  Saw the reports in NJ/se NYS/n CT.

Saving the topic posts for big flooding, more widespread SVR wind where concentrated BIUG damage or most involved. 

Seems like the forum is going well as is.  

Looking forward to the transition to 90+ heat and 70+ dew points sometime after June 6 through at least part of the second week of June.  I see CPC likes it pretty warm week 3-4 and NAEFS has been bullish on the heat coming in June.  This rain is making more surface moisture available for the Bermuda High to work with come June 6 onward.

Newark is on track to beat the record low max of 60° today. Newark has never had a record low max during the last week of May with a 96° monthly high temperature. This exceeds the 1953 May maximum temperature of 91° by 5°. All the other years had 0-1 days reach 90° in May vs 4 days this year.

40’s and rain in late May is just wrong, we routinely see nicer days in the dead of winter. If it was 20-30 degrees warmer I wouldn’t mind, we really needed the rain, and the wind component is a nice touch as it’s been very boring lately.

Was down to 45 last night and now up to a balmy 48 on this what feels more like Christmas Weekend.  2.01 in the bucket and still raining anyone who was fearing a long lasting dry spell or even a drought should just look at the last and most recent 15 similar dry spells and how they ended much like this, with a deluge.   Reports of power outages last night with the stiff NE wind and gusts to 30 + MOHs.  Socked in clouds  through and perhaps even Memorial day itself.

This does look to be just a speed bump in the overall switch to warmer that started in mid May, albeit a speed bump that busts a few tires (worst timing too).  Ridging building along the east coast should dominate the next week to ten days with more SW flow estabishing June 2nd 'bermuda high.  Warm and humid with spikes of heat and brief cooldowns and storms firing routinely.  The park may need a week to dry out before approaching 90 but other warmer spots, including LGA may see 90s as soon as Jun 6th. 

 

So hang in there a 50 more hours and it should be right back to a more classic hazy humid and warm - hot before you know it.  I think the GFS may be a bit too cloudy / wet Tue - Fri this week, we shall see. Here's hoping anyway
