We’ll have to see if the WAR can link up with the Plains ridge near the start of July for more extended heat than these 1 to 2 day brief surges of 90s.

Yeah, Corona Queens and Newark both made it to 103°on 6-30-21. It was the warmest June temperature on record at Newark. The new NYC micronet is a valuable addition to our local weather observations. 13th St./16th / Alphabet City 101 75 90 107 75 91 35 0.40 26 9:10pm 11 9:10pm 25.9 160 Ave. / Howard Beach 91 76 83 102 76 89 51 0.08 28th St. / Chelsea 99 75 89 103 75 94 35 0.98 30 8:50pm 13 9:05pm 20.4 Astoria 100 73 89 107 73 95 36 0.58 26 9:00pm 13 9:05pm 23.8 Bensonhurst / Mapleton 97 78 88 107 78 84 39 0.00 26.3 Bronx Mesonet 98 75 88 103 75 90 37 0.38 35 8:55pm 15 9:00pm 28.7 Brooklyn Mesonet 95 75 86 103 75 87 41 0.00 31 10:05pm 18 9:30pm 26.9 Brownsville 97 76 88 106 76 89 40 0.19 Corona 103 75 90 109 75 92 34 0.35 E 40th St. / Murray Hill 99 74 89 104 74 93 37 0.66 Fresh Kills 99 73 88 105 73 94 36 0.06 27 9:40pm 16 9:40pm Glendale / Maspeth 99 74 89 107 74 93 37 0.33 Gold Street / Navy Yard 100 75 88 105 75 90 35 0.30 32 9:00pm 16 9:00pm 26.2 Lefferts / South Ozone Park 95 74 85 105 74 93 49 0.10 Manhattan Mesonet 97 73 87 102 73 94 39 0.98 35 8:45pm 19 8:50pm 21.6 Newtown / Long Island City 99 74 89 104 74 90 36 0.25 25 9:10pm 11 5:55pm 24.3 Queens Mesonet 94 73 86 103 73 92 45 0.27 38 9:05pm 20 9:10pm 24.0 Queensbridge / Dutch Kills 100 74 90 105 74 95 34 0.63 19.5 Staten Island Mesonet 97 72 86 104 72 94 40 0.12 36 9:40pm 17 9:40pm 24.2 TLC Center 97 73 87 101 73 94 38 0.64 26 8:50pm 11 9:55pm 23.6 Tremont / Van Nest 103 75 90 110 75 92 32 0.45 24 8:50pm 12 5:05pm 2 Data for June 30, 2021 through June 30, 2021 Click column heading to sort ascending, click again to sort descending.

Parts of NYC away from the sea breeze are just as hot as the Newark area is. The NYC micronet is doing a good job at filling in the temperatures between the airports which are right on the water.

Pretty impressive omega pattern for the 2nd half of a June. A piece of the Great Lakes heat comes east with 90s potential on Friday. Then a quick temperature drop to lows in the 50s and maybe 40s interior for Sunday morning. We’ll have to see how much heat can come east later in June when the ridge flexes to our west again.

This summer is starting out with EWR having warmer temperature departures than LGA. We saw a pattern like this last summer. It’s a reversal from LGA having the higher departures from 2018 to 2020. So our stations are very sensitive to prevailing wind directions since they are located so close to the Atlantic and LI Sound. JJA 2022 so far EWR…+3.5 LGA….+0.6 JJA 2021 EWR…+2.5 LGA…..+0.7 JJA….2020 EWR….+2.4 LGA…..+4.2 JJA….2019 EWR….+1.3 LGA…..+2.0 JJA……2018 EWR….+1.3 LGA……+2.6

The sea breezes are keeping areas to the east of Newark much cooler than the +3.5 there. EWR…+3.5 NYC…..+1.0 LGA……+0.6 JFK……+1.4 ISP…….+1.9 BDR……+1.1 HPN……+1.3

Highest dewpoint in 11 years for CVG to 80°. So the record heat and humidity will be very impressive to our west this week. Temperatures will rise to the upper 90s to around 100° next few days around the Great Lakes. Past record heat for the Great Lakes in mid-June also made it here. The 12z OP Euro has potential highs in the mid 90s for for Newark on Friday with a slower cold frontal passage and more sun. The other models including the EPS mean were cooler with more clouds and storms. The OP Euro matches past experience. So if the cooler models in the low 90s are right, then it would be a first for our area in mid-June. Looks much cooler behind the front for the weekend.

Getting some weakening of the La Niña following the record strength in the spring.

Classic MCS possible derecho track ESE from the Great Lakes to our south tonight into tomorrow.

Rainfall amounts are usually quite variable when we rely on convection this time of year. Some parts of the region have had a good soaking.

The 12z HRRR rakes the MCS to our south closer to the better instability.

An early June statistical model forecast for the average September Arctic sea ice extent came in at 4.5 million sq km.

Summer starting out with the warmest departures west of the Hudson. EWR….+3.5 PHL….+2.8 NYC….+1.1 LGA…..+0.6 JFK…..+1.4 HPN….+1.3 ISP…….+1.7 BDR…..+1.2

Yeah, the Euro has near record 850s of +24C + in Chicago and around +18C for us next Friday. But the GFS and Euro both have clouds and convection here. The ridge on both models looks a little narrower than we typically get with a 594dm heat dome to our west. When Chicago has gone 94°+ around June 14-15th in the past, Newark has recorded near to record highs from 95° to 102°. But the Euro and GFS have enough clouds and convection to keep Newark below those levels. So we’ll see how things go later next week here with regard to the clouds and convection. Past years with near to record Chicago heat June 13th to 14th. Newark highs for June 13-21 in those years 2012….99° 1994….102° 1991…..97° 1988….99° 1987….96° 1954….95° 1952….98°

If we only make it to the low 90s like the GFS has later next week, it would be well below the mid to upper 90s forecast near the Great Lakes.

Yeah, it’s rare for mid to upper 90s around the Great Lakes not to make it here in June.

The heavy thunderstorms this morning caused an unusually large temperature error even by NYC standards. The wet vegetation growing over the sensors combined with the deep shade for one of the biggest temperature spreads of the season. Probably water dripping onto the thermometer combined with strong transpiration cooling the temperature under the trees. EWR….87° LGA…..85° NYC….81° JFK….84° ISP…..86°

Impressive wind gusts in Suffolk for early morning thunderstorms this time of year.

Strong thunderstorms moving through with some severe warnings down around Monmouth.

Strongest heat remains to our west through the solstice on the 12z EPS. So we’ll probably have to wait until late June or July for our first official heatwave with 3 days or more in a row reaching 90°. Last June we had our first heatwave from the 5th to the 9th.
