Showers are possible late next week, along with cool readings.

So who was the winner with all the rainfall?  I need a new rain guage.

Serial derecho heading into western New York now. Started yesterday in Wisconsin and crossed multiple Great Lakes. These monsters often create their own atmospheric conditions and can last much longer then modeled. Not saying it makes it here, but something to watch.

Hopefully with your projected 3C of warming, JFK and EWR will see 100 degree temps a few times every summer even with onshore flow.

Do you think a time will come when we could hit 100 degrees even on a southerly wind?

 

The wild card will be what happens to rainfall to our west. Some of long range models shift the Western Drought into the Plains in the coming years and decades. This could potentially alter the more onshore flow we have been experiencing over the last decade. So in that case we would regularly see 10 or more days reaching 100° over NJ and 5+ on Long Island. But it would require the ridge east of New England shifting to our West. This is highly speculative since the current pattern we are experiencing has been different from that scenario. No matter how much the climate warms, we aren’t going to see many 100° days with onshore flow dominating.

Do these models show why the drought would shift to the plains? Like what atmospheric changes are shown that shift the drought east? Basically why would a warming world do that is what I'm asking.

Maybe if this rampaging Pacific Jet is a permanent thing now the West would be wet and Plains would start to dry out. But who knows.

Some of the models show the severe drought shifting eastward into the Plains from the 2030s into the 2050s. But it would require the ridge east of New England shifting for us to get westerly winds from the Plains.

I suppose a compromise could be possible with both ridges linking up and alternating westerly and southerly flow. But this hasn’t been the case in the last decade with more of a trough over the Great Lakes and Ohio Valley and inshore flow.

Notice how these days the common summer pattern has been a ridge east of New England and over the West. But from 2010 to 2013 when we had all the 100° heat and westerly flow there was a ridge in the Plains.

65 / 64 low level clouds and fog.  Some pokes of sun and low 70s could trigger some storms this pm and evening.  Saturday the warmest of the next 10, and with enough sun and break between the front 90 degree could be approached in the warmer spots otherwise low - mid 80sn stoems by the late afternoon/evening - pending timing of the front.  Sunday - Tuesday nicest - dry stretch with near normal. 

 By Wed clouds and showers are back in the picture and with a stiff E/ENE flow Thursday looks quite ugly and cool.  Brunt of the rain between Wed - Fri then could be right on Memorial Day.  Trough stingy in the east right through the end of the month. 

Heat building in the rockies looks to start eastward push early next month.

1988 - Afternoon and evening thunderstorms developing ahead of a cold front produced severe weather from Florida to New York State. Unseasonably warm weather prevailed in the north central U.S. Havre, MT, reported a record high of 95 degrees. (The National Weather Summary)

1989 - Thunderstorms developing ahead of a cold front produced severe weather in the south central U.S. Thunderstorms spawned twenty tornadoes, and there were 180 reports of large hail and damaging winds. A tornado at Cleburne, TX, caused 30 million dollars damage. A violent (F-4) tornado touched down near Brackettville, TX, and a strong (F-3) tornado killed one person and injured 28 others at Jarrell, TX. Thunderstorms also produced softball size hail at Shamrock, TX. (The National Weather Summary) (Storm Data)

That would be a HEC in February. Timing is cutting it close with MDW. We definitely do not want that slowing down.

Any storms tomorrow or just sunny and hot?

There is some small scattered stuff on the models, mostly north and west of the coast.
