June 2015 Discussion & Observations

Newark has seen the more + departures around the region with a +2 and +6 the last few days after a solid negative first week. It's easy to log positive departures now as the normal daily highs are still in the upper 70's on

June 10th.

 

NYC, EWR, LGA, JFK, TTN were all +6 yesterday daily vs avg.

Well..Newark came in just a hair above since its the official furnace of our area.

 

Got cha.

 

The whole stretch from  CNJ into NENJ is the areas warm spot on many occasions.  EWR high was a degree from LGA/JFK, New Brunswick yesterday.   

 

Back to June - today looks like a gem!

That south wind always kills heat chances there. Depending how people take it, it either sucks or they're thankful

Luckily tomorrow looks to be the most likely day to reach the 90's, and low 90's at that. Dew points however will be in the upper 60's to low 70's so the humidity will be oppressive. If Warlock loves it so much, I suggest we lock him inside of a brazen bull.

Lmao yeah definitely. I don't mind a day or 2 of 90/67. That can also help trigger tstorms later in the afternoon as that front gets closer

Water temps are still in the upper 50s. Cold for this time of year. If we didnt have the warm May, it probably would be even colder.  I think this will be a big week for warming the Ocean. Once we get a little more humidity in the air, it keeps overnight lows from dropping. Lowest Lows for the next week will be about 62/63. So the ocean should be at least in the low 60's by the end of the weekend I think.

With the El Niño-driven high-amplitude MJO having moved into Phase 2, warm anomalies have overspread the East. At the same time, much as occurred in June 1997, the PNA has now gone negative after a long-duration positive regime.

 

June 1997 saw the MJO reach Phase 2 on June 13.On June 16, the PNA went negative, ending a 23-day PNA+ regime. Following the end of the PNA+ period, the PNA remained negative for 19 days (June 16-July 4). During that timeframe, the PNA fell to as low as -2.079. Two days (11%) saw the PNA at or below -2.000 and 11 days (58%) saw the PNA at -1.000 or below.

 

This year, the PNA was positive on 25 out of 26 days during the May 16-June 9 timeframe. The MJO had moved into Phase 2 on June 6, with the PNA's flip to negative occurring four days later. The timing was remarkably close to that of 1997 and in both cases, the MJO was at high-amplitude. In recent days, the GFS ensembles have grown more bullish on the PNA-. The latest forecast shows numerous ensemble members taking the PNA to or below -2.000 for a time.

 

The end result should be that the warmer than normal anomalies that have now arrived in the East should persist, perhaps for at least two weeks or longer. In addition, the Pacific Northwest could turn cooler than normal. Just a few days ago, the GFS ensembles were indicating continued unseasonable warmth there. Now, they should near normal conditions for the June 15-20 and June 20-25 periods.

We really have't missed any opportunities for massive North Pacific ridging in recent years. 

The ridiculously resilient ridge has been the common denominator. This version is just a little

further west near the Aleutians so it's allowing a more -PNA and stronger ridge over the East.

Bodes well for next winter when wavelengths are longer..

I think tomorrow's a non-event for the majority of us. The isolated T-storms that do manage to initiate could become quite strong to potentially severe, but overall, I'm not impressed with the forcing.

 

The weekend is also trending less impressive, but there's time for that one to change.

The week of June 15th-22nd should be warmer than normal with potentially the first shot at an official heat wave for the I-95 corridor. I think the last week or so of June will feature a resumption of lower heights in SE Canada as the PNA neutralizes and EPO remains negative. Temperatures in the Northeast should trend back toward normal values for Jun 24th-30th.

Starting to look like whatever comes in on Saturday is delayed until after sunset with the low pressure system ending up a lot further North than first predicted a few days ago.

Stick a fork in that then, not going to get much without daytime heating this time of year with a cold front.  Back to endless dry days IMO

Probably overdone but the 18z NAM has 3500+ J/KG of SBCAPE over NNJ tomorrow afternoon with convection firing right along the boundary. Low to mid 90's with dew points in the lower 70's will create a highly unstable atmosphere if something can get going.

given the heat and time of day, I'd think we'd see a few big cells.  While most will see nothing, a few areas could get a nice boomer.
