donsutherland1 Posted August 19, 2019 Share Posted August 19, 2019 Today saw New York City reach 90°. As a result, August now has a positive monthly anomaly near 0.4°. Overall, August remains on course to be warmer than normal in the Middle Atlantic and southern New England regions. Anchorage, which came off its warmest month on record, remains on track to record its warmest summer on record. There is also a chance that 2019 could set a new August record for highest mean temperature on record. If so, that would be the third consecutive monthly record set this year. The ENSO Region 1+2 anomaly was -0.6°C and the Region 3.4 anomaly was +0.4°C for the week centered around August 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.35°C and the ENSO Region 3.4 anomaly has averaged +0.42°C. Neutral-warm ENSO conditions are in place in Region 3.4 with neutral-cool conditions in place in Region 1+2. There is considerable uncertainty about the ENSO evolution later this summer into the fall. Some of the guidance continues to show the development of neutral-cool ENSO conditions. The SOI was +7.46 today. Today, the preliminary Arctic Oscillation (AO) figure was -0.676. A general tendency for blocking could persist into the last week of August. By that time, the AO could move toward neutral to positive values. This evolution of blocking will promote a generally warm or perhaps very warm remainder of summer. Since 1950, there was only a single year that saw the AO average -1.000 or below in May and -0.500 or below in June (the preliminary June 2019 average was -0.665): 1993. 1993 featured much above normal readings in the East during the late summer (August 15-September 15 period) and predominantly cooler than normal readings across the western third of the nation during much of the summer. In addition, since 1950, there have been four prior cases when the AO averaged -0.500 or below in both June and July: 1957, 1958, 1993, and 2009. In three (75%) of those cases, August wound up warmer than normal. August 1993 was the warmest case. The mean anomaly from those cases suggests that the Middle Atlantic and southern New England areas could be approximately 0.5° to 1.5° above normal overall during August. On August 17, the MJO was in Phase 1 at an amplitude of 0.754 (RMM). The August 16-adjusted amplitude was 0.348. Finally, based on sensitivity analysis applied to the latest guidance, New York City has an implied 64% probability of having a warmer than normal August. 3 Link to comment Share on other sites More sharing options...

Ah I missed it while at the beach, Robert Moses. so foggy over there took a long time to burn off, but turned out nice when it finally did. Everyone talking about this t storm that came through at home. No rain now, but lots of lightning in the distance. Link to comment Share on other sites More sharing options...
Juliancolton Posted August 19, 2019 Share Posted August 19, 2019 The storms here have been accompanied by frequent lightning flashes this weekend, but almost no clearly visible bolts. I assume IC lightning is favored vs. CG with marginal lapse rates. Or maybe you just don't see them with the high dews/low LCLs? Link to comment Share on other sites More sharing options...
psv88 Posted August 19, 2019 Share Posted August 19, 2019 Storms blew up just to my east. Nice little cell in central Suffolk, I see the lightning. Good thing I watered the lawn. Commack has a rain shield the summer. Never seen anything like it. Link to comment Share on other sites More sharing options...

I was in NJ and there was a fair bit of C to G lightning that we could see from the GSP. It was a pretty good sized standalone cell to the east of the parkway with a nice rain column and high top. I like watching stuff like that evolve while I'm traveling. Is it really going to be wet every day this week? One more beach day before the kids go back to school would be nice. Which day is most likely to be worth the effort and is early that much better to be worth the extra effort? Link to comment Share on other sites More sharing options...

Didn't take long to recover overnight, though. There was a lot of cloud-to-air lightning with the cells near the city yesterday afternoon and 1 "bolt from the blue" here in BK. Haven't seen that in awhile. 1 Link to comment Share on other sites More sharing options...

purduewx80 Posted August 19, 2019 Share Posted August 19, 2019 One of the nice things about the SPC soundings is that they show the max mid-level lapse rates, which may not always correspond to the standard 700-500mb levels. Both IAD and OKX sampled lapse rates above 7C/km this morning. In fact, they're steep from ~950 up to ~600mb. The warmer temps at 500mb are what's keeping 700-500 rates much lower. Despite the fcst modest shear, this is a decent signal for some strong winds this afternoon: Convection should pop pretty quickly near and just west of the city by 2-3 this afternoon. 1 1 Link to comment Share on other sites More sharing options...

A lot of guidance showing the same thing this evening, except dew points may not recover until tomorrow night. Might not see JFK make it to a Td of 75 tomorrow, but it's looking more likely that Thursday stays humid w/ the slower advance of cooler/drier air.

Awesome shot, that’s right down the block from my house. Finally had a decent amount of rain last night at home and a full on monsoon at work on the uws. Couldn’t have come at better time as I was heading into emergency watering. looking forward to a good lighting show this evening 1 Link to comment Share on other sites More sharing options...

gravitylover Posted August 19, 2019 Share Posted August 19, 2019 Ooh boy I got a whopping .23" yesterday. That puts me at about .5 for the last few weeks. At least the rain keeps falling at the right time to soak in overnight so things are growing well but the ground is hardpan and dusty. Maybe the wetness coming up replenishes the soil moisture somewhat. Link to comment Share on other sites More sharing options...
