This week is going to be on par if not exceeding 2012's heat wave, its been 14 years since we have had heat of this magnitude. Nothing typical about this unless you are in Dallas or something.

We're unfortunately due for a legit heatwave. We dont get them like we did decades ago when we would frequently multiple per summer. These days we run up departures with warm summer nights. Hopefully its a one and done deal after this week. Heat looks transient.

That will change a couple times

Summers preceding El Ninos are typically comfortable (in the mean). As this June has been. The implying that it doesn't get hot is ridiculous. Were actually due for a legit heatwave.its gonna be hot and humid, and likely transient.

Definitely not, especially with so many places that will approach/exceed 100 over a large expanse of the country, with a ridge that is only 594dm. Watch us get a 600dm ridge later in the season, and no it won't be a typical stretch of summer heat then either.

The thing that helped 2024 was that it was really dry in that period. It’ll be interesting to see if this weekend’s rain has any affect by later this week.

Literally the last 2 weeks has been colder than average every day here.

What's with the cool pocket off of the northeast.

Yes 1875-76 was actually a very mild winter here, coming off the record cold year of 1875. Always a bit ironic here- 1875 is by far the coldest year on record, yet the last day of the year, Dec 31, still holds 1875 as the record high at 65°.

I went about 3 weeks without feeling 80° (Alaska trip then prolonged cooler than avg here). Its going to feel unbearable. Not that ill be out in it, but still.

Multiple days in the 100s for Philly certainly constitutes as “extreme”, even if not in this sub. Hell even Detroit may see triple digit heat along with a high number of consecutive days well into the 90s. This isn’t a “typical stretch of summer heat” (especially considering this is a pre super nino summer), stop downplaying it.

I talked to my neighbor this evening and he literally had no idea heat was coming.

Looks like forecast highs have come down a tad. We will see.

0.21" over the weekend for me, although that may be a little low since the Tempest struggles a bit when it comes to measuring drizzle, and it was a full on drizzle fest for a while this morning.

Sold the house in Salem. Moving to Thailand. Wife (she's from Thailand) and I built a retirement home there about 4 years ago. No more snow for me. 100% AHATT

Good consensus on basin-wide super-event.

Time lapse of that FF warned storm that just moved through Philly at sunset. With some fireworks for good measure.

20°C Isotherm: the 20°C layer that separates the colder waters from the warmer ones in the deep-sea profile (up to 500 meters depth) where #ElNiño develops. Over the last 3 months, that layer has been becoming almost horizontal (a sign of an intense event). The slope of the thermocline today is comparable to the one observed at a similar time in 1997. This can be seen in the measurements of how deeply it is submerged compared to its normal values at 95°W (which is the eastern boundary of the TAO buoys that measure the temperatures of the first 500 meters of ocean depth and the gateway to warming in the Niño 1+2 Region or where we measure #ElNiñoCostero). Currently, it is about 50 meters below its usual position. It is observed as it appeared in 1997 and exceeding in depth all intermediate #ElNiño events. Two other relevant observations: the first is the surface displacement of the warmest waters of the equatorial Pacific, which at the start of the animation were in the western basin and today are moving through the central Pacific (see movements of the 29°C and 30°C isotherms at the surface). The second: a new warm Kelvin Wave forming embedded within the far western end of the large subsurface warm water anomaly under 170°W. In the animation, I have slowed down the speed of the last frames so that it can be appreciated how the mass of warm water sinks in the "tail" of the larger warm mass. There is the warm Kelvin Wave or downwelling wave. Currently, the continuous sinking of the 20°C isotherm has already produced an anomaly of +8°C at the eastern end (near South America) of the temperature profile. In 1997 we reached values between +11°C and +12°C. Soon we will see a 9°C anomaly appear within the +8°C one. This is the highest heat content in June between 180° and 100°W since the +2.25°C of June 1997. To date, we are at approximately +2.10°C.

yikes dude - that looks like Arizona or California during the dry season. Things here are pretty green thankfully as we've had enough periods of rain to keep things looking OK.

Well this was completely unexpected and much needed... Solid tstorm over my area.. Heavy rain past 25 min..

Or 18z..I guess 12z finally did run

Down to light rain now and currently have 1.84" so far bringing me up to a whopping 8.09" for the month so far! Temp/dp now 69.

Its not like we seen last month,in the upcoming weeks into July the WWB is getting combatted with EWB.Even the EPS shows this to some extent.But this still could have destructive interference with the MJO signal with RW AND KW,regradless the chances of MJO moving out of the WP seems real to me,its not going to happen for awhile

Was there no 12z European today?
