Newark is on track for another 95°+ high temperature today. So Newark currently has 5 days of 95°+. This is the 2nd highest on record by June 25th. But this is the first of the years with no heatwave by June 25th. The first heatwave could finally arrive between June 30th and July 2nd if the Euro is correct.

The cooler subtropical Atlantic and lack of a SE Ridge this month is a shift from the persistent La Niña background state at least on the Atlantic side.

MPO was the big rainfall winner coming in at the 16th wettest June so far.

This may be the first time that two consecutive Junes had a completely opposite 500 mb pattern. Notice the NW and NE troughs this year where the ridges were last year. The ridges in the Plains and Hudson Bay replaced the troughs from last June.

This month was a return to the New England trough pattern which has been absent for so long.

The persistent low pressure to our east has really cooled off the SSTs in the Western Atlantic. Much cooler SSTs than at the same time last year. The area is actually below normal for a change. So we get these brief warm ups followed by the trough returning to New England.

This weekend looks to follow the same 2 days of 90s theme before the next cool down.

Almost looks like a PRE. But with a cutoff low instead of a tropical system to our south.

I haven’t been able to find another June with such a strong ridge in the Plains and near Hudson Bay. My guess is that Matt Hugo is correct about the May +AAM spike and lingering blocking influence. So we get the stronger Hudson Bay blocking running with the La Niña background state of heat and drought in the Plains. Almost looks like the +AAM blocking influence got delayed for several weeks and waited to show up in June.

Texas is one of the warmest parts of the country this month. DFW is having a top 10 warmest June. So it makes sense with a very strong ridge in the Plains. But the near record block just north of Hudson Bay typically doesn’t go with this type of pattern. So this is why the 100° heat near the Great Lakes has stayed to our west which is unusual. The other out of place feature is the deep trough near the Pacific Northwest. Much stronger blocking this June for DFW top 10 warmest composite 2022 vs composite

Another extreme with this highly amplified Omega Block.

Getting the heaviest downpour of the whole storm now in SW Suffolk. The NYC crew is happy that this isn’t a snow event.

Toledo ,Ohio had a record high of 100° yesterday. So far Newark only has a June monthly high of 95°. This is the coolest on record for all the 100° June years in Toledo. Most years Newark also made it to 100° in June. So this is an unusually amplified omega blocking pattern for this time of year.

First guess for July 4th weekend is for frontloaded warmth. EPS is warmest on Friday. Then a cold front with storms on Saturday. Cooler and hopefully drier for Sunday into Monday as Canadian high pressure builds into Northern New England.

The persistent blocking pattern temporarily cooled off the Western Atlantic mid-latitude SSTs with the strong 50/50 low replacing the WAR and SE Ridge.

Unless we get an organized tropical system, convection is usually hit or miss this time of year.

The seasonal models are often low skill especially for the winter. Long range MJO and SPV forecasts get really difficult beyond week 2 during the winter. But the seasonal models seem to have better skill during the summer some years. While I don’t usually look at the CFS, the big IOD reversal it’s forecasting for next winter would be fun. The forcing shifts from the Maritime Continent to west of the Dateline in the WPAC. While the forecast may be completely wrong, forcing west of dateline would support at least a strong -EPO +PNA like we had in January. The state of the AO and NAO usually is unknown until the winter actually starts. Is Maritime Continent cooling and WPAC warming next winter fact or fiction? Current Winter forecast

Really unusual for the jet to be blowing this strong out of the north this time of year. It’s near a record according to the NEEFS. So this is why the convection is dropping SSE out of Canada.

The blocking started with the final stratospheric warming in late March. Sometimes once blocking becomes established, it just keeps going. But the strength of this blocking is unusual for June. Notice how strong the blocking is this month NE of Hudson Bay. So it will be interesting to see how long it can persist. Blocking since March 25th Blocking since June 1st

This is a different type of June pattern than we have seen in recent years. The heat ridges to our west have usually come east. This June we have the strong blocking pushing back against the heat dome. Most years the blocking is too weak in the summer to challenge the ridge to our west. So it will be interesting to see if the CFS is correct about the blocking continuing into next winter.

This is one of the strongest Omega Blocks that we have seen in June. https://www.theweatherprediction.com/habyhints/144/

The extended EPS for the start of July looks similar to the July forecast issued on June 5th. Rockies ridge with another ridge east of New England. If this pattern verifies, then the strongest heat in July relative to the means will be to our west. July Euro forecast issued on June 5th

The stationary front will serve as a focus for the convection this week. So a continuation of the wet June pattern for parts of the region. Several spots are already in excess of 4-5”.
