Parts of TX and FL are likely up there.   Cheaper living, lots of land. less taxes and nice weather will do that!

The Austin/San Antonio areas are absolutely exploding. I lived there 5 years ago and without improved infrastructure and accommodations for the accelerated growth, they're in for some hurt. The congestion in Austin is already bad enough, and little mass transit for nearly a million people other than two light rail lines and bus. For vehicles it's MoPac Expressway and I-35 for main thoroughfares, and both are constantly backed up. 

Weatherwise, April/early May are the best severe weather times there, and it can be good. I had several tornado warnings and many severe warnings. EF1 went maybe 2 miles from me once, other times 75 mph straight line winds and golf ball hail. The best tornado area is Waco on north in TX. May and October can be very wet. May 2015 was crazy in Austin for how much rain there was, 20" that month I believe. October 2015 had the heaviest rain I've ever seen (even the pre-Irene 2011 rain event here) from the Hurricane Patricia remnants off the Pacific. Winter is changeable but generally add 10-15 degrees from this area for what you get there. Despite the insane snow/ice this winter, when I was there we had one morning with some sleet and ice that was a minor glaze, that was it. Summer is atrociously hot and humid, most days in late July/Aug are near or over 100 before heat index. You're close enough to the Gulf for the humidity and inland enough for the higher actual highs. Also it's generally dry in the summer, the afternoon T-storms often fire closer to the gulf. The nice months are the winter months when you can get a warm airmass, and Oct-Nov/March. 

Landwise, plenty for sure in TX but it quickly goes from suburban/exurban not far from Austin downtown (like 10 miles) to nothing (and I mean nothing not even a town) west of there on Rt 71 or 290. 

Awesome people watching, very friendly/laid back vibe, great events such as SBSW/Austin City Limits and plenty of good jobs but not so much in my industry now. Living costs however are skyrocketing (part of the problem with exploding population).

Tomorrow will be another partly sunny, but somewhat cooler day. The weekend will start off variably cloudy and unseasonably cool. Showers and even a thundershower are possible.

Generally somewhat cooler than normal to near normal temperatures with perhaps a day or two of much below normal readings will likely continue at least into the middle of next week. Such cool shots have often occurred with a cold ENSO Region 1+2 anomaly, as is currently the case.

As had been the case with April, the closing week of May could wind up warmer to much warmer than normal. In the four cases where the MJO reached Phase 1 at an amplitude of 2.000 or above in comination with a cool ENSO Region 3.4 anomaly during the May 1-10 period, as occurred this year, three wound up with warmer to much warmer than normal conditions. At New York City, the mean temperature during the closing 7 days of May was 72.7° during those three cases while it was 72.0° at Philadelphia. The 1991-2020 means were 67.9° and 69.7° respectively. Only May 25-31, 2013 (monthly ENSO Region 1+2 anomaly of -1.38°C) was cooler than normal. However, 90° heat arrived on May 29 in Philadelphia and May 30 in New York City during 2013.

The ENSO Region 1+2 anomaly was -1.0°C and the Region 3.4 anomaly was -0.4°C for the week centered around April 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.87°C and the ENSO Region 3.4 anomaly has averaged -0.45°C. Neutral-cool ENSO conditions are now developing. Neutral ENSO conditions will likely be in place by the end of spring.

The SOI was +32.04 today. That was the highest figure since December 31, 2020 when the SOI was +32.12.

The preliminary Arctic Oscillation (AO) figure was -0.544 today.

On May 4 the MJO was in Phase 1 at an amplitude of 2.987 (RMM). The May 3-adjusted amplitude was 3.395 (RMM).

In late April, the MJO moved through Phase 8 at an extreme amplitude (+3.000 or above). Only February 25, 1988 and March 18-19, 2015 had a higher amplitude at Phase 8. Both 1988 and 2015 went on to have an exceptionally warm July-August period. July-August 1988 had a mean temperature of 79.1°, which ranked 4th highest for that two-month period. July-August 2015 had a mean temperature of 78.9°, which ranked 5th highest for that two-month period. September 2015 was also the warmest September on record. The MJO's extreme passage through Phase 8 could provide the first hint of a hot summer.

Chris, can you do one for monthly rainfall patterns?  That would be interesting to see too.

Also can you a break down, monthly avg maxes vs monthly avg mins?  Thanks!

Sort of but not really. The way they develop out there includes new green areas that were just beige before. These newly landscaped and grassy areas add to the RH and general cooling in the valley bringing the temps down (theoretically).

we're doing green in NYC too.  Glad to see it, get rid of that concrete crap and replace it with community gardens for healthier food in the food deserts too.

 

I heard we have 65 bee farms in Manhattan, bees are doing well here because of the lack of pesticides.

Our precipitation is increasing along with the temperatures. Rural, suburban, and urban sites are experiencing a faster minimum temperature rise than maximum. The maps below show the rate of change per decade.


https://www.sciencedaily.com/releases/2020/09/200930194912.htm

Days warmed more quickly in some locations, and nights did in others -- but the total area of disproportionately greater night-time warming was more than twice as large.

The study shows this "warming asymmetry" has been driven primarily by changing levels of cloud cover.

Increased cloud cover cools the surface during the day and retains the warmth during the night, leading to greater night-time warming. Whereas, decreasing cloud cover allows more warmth to reach the surface during the day, but that warmth is lost at night.

The next 8 days are averaging 57degs.(49/65), or +4.0.

Still no warmup till at least after mid-month.   EURO still trying to reach 70 over the next 10 days.

52*(48%RH) here at 6am, m clear.      55* by 8am.       Reached 64* around 5pm.

Morning thoughts...

It will be partly cloudy and pleasant today.  Temperatures will likely reach the middle 60s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 65°

Newark: 67°

Philadelphia: 67°

It will be mainly cloudy and unseasonably cool tomorrow. Showers and perhaps thundershowers are possible.

Unusual temperature pattern so far this May. Newark reached 86° during the first week of the month. Looks like our first time since 2010 with no May 8-15 follow up 80s in the forecast. Just goes to show how impressive a MJO event this was combined with lingering April blocking.

Next 10 days looking like mainly 60s, (50s tomorrow) and an outside chance that some of the warmer spots may touch 70 or low 70s Wed (5/12) or Thu (5/13).  May 18 still looks like the start of a change to higher heights / warmer temps with the following week to 10 days (end of May) perhaps featuring the opportunity for strong warmth.

Long time lurker during the winter months and I appreciate all the info from the folks on here. I have my daughter's bat mitzvah this Saturday and I'm wondering if anyone can give me their thoughts on outdoor festivities for Saturday after 1PM. The weather models look pretty iffy 3 days out. 

Bumping this because I'm a little over 24 hours out. Looking at the early 12z models it looks like maybe the rain might dodge Rockland. Is it still too early to feel any confidence?

Models have pop up convection tomorrow under the deep upper low and cold pool. So it will be a hit or miss type affair during the day. Somebody could see the ground whitened with small hail under the steep mid-level lapse rates and low freezing level.

Major problems for the Southwest if those precip trends continue, and they’re in another severe drought this year. I read that an official water shortage may be coming soon for parts of NV and AZ because of low water levels on the Colorado River and lakes.

Thanks, when will we get to the point where cloud cover wont matter and warming will accelerate to the point that we'll have several 100 degree days each year?  I heard that might happen by 2050 and we'll have an Atlanta type of climate by then.

At some point carbon dioxide and methane forcing will break the cap that clouding provides and we'll enter new territory.

Lake Mead wont be able to provide water after a few more years....it'll probably happen by 2030.

NYC got into the low 30's last May...A standard recprd low with the lowest 34 degree temp for so late in the season...it was the first time since 1978 NYC got below 40 in May...years since 1960 that had temps below 40 in May...it happened seven times in 16 years...then it took 42 years for it to happen again...

1963...38...

The weekend will start off variably cloudy and unseasonably cool. Showers and even a thundershower are possible. However, the afternoon could be fairly dry. Temperatures will likely remain in the 50s in New York City and Newark.

Generally somewhat cooler than normal to near normal temperatures with perhaps a day or two of much below normal readings will likely continue at least into the middle of next week. Such cool shots have often occurred with a cold ENSO Region 1+2 anomaly, as is currently the case.

As had been the case with April, the closing week of May could wind up warmer to much warmer than normal. In the four cases where the MJO reached Phase 1 at an amplitude of 2.000 or above in comination with a cool ENSO Region 3.4 anomaly during the May 1-10 period, as occurred this year, three wound up with warmer to much warmer than normal conditions. At New York City, the mean temperature during the closing 7 days of May was 72.7° during those three cases while it was 72.0° at Philadelphia. The 1991-2020 means were 67.9° and 69.7° respectively. Only May 25-31, 2013 (monthly ENSO Region 1+2 anomaly of -1.38°C) was cooler than normal. However, 90° heat arrived on May 29 in Philadelphia and May 30 in New York City during 2013.

The ENSO Region 1+2 anomaly was -1.0°C and the Region 3.4 anomaly was -0.4°C for the week centered around April 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.87°C and the ENSO Region 3.4 anomaly has averaged -0.45°C. Neutral-cool ENSO conditions are now developing. Neutral ENSO conditions will likely be in place by the end of spring.

The SOI was +22.69 today.

The preliminary Arctic Oscillation (AO) figure was -1.013 today.

On May 5 the MJO was in Phase 2 at an amplitude of 2.740 (RMM). The May 4-adjusted amplitude was 2.987 (RMM).

In late April, the MJO moved through Phase 8 at an extreme amplitude (+3.000 or above). Only February 25, 1988 and March 18-19, 2015 had a higher amplitude at Phase 8. Both 1988 and 2015 went on to have an exceptionally warm July-August period. July-August 1988 had a mean temperature of 79.1°, which ranked 4th highest for that two-month period. July-August 2015 had a mean temperature of 78.9°, which ranked 5th highest for that two-month period. September 2015 was also the warmest September on record. The MJO's extreme passage through Phase 8 could provide the first hint of a hot summer.

Based on sensitivity analysis applied to the latest guidance, there is an implied 68% probability that New York City will have a cooler than normal May (1991-2020 normal). May will likely finish with a mean temperature near 62.0° (1.2° below normal).

The next 8 days are averaging 56degs.(49/63), or about -6.0.

GFS back with the 90's during Week 3.      Some 80's with a 90 thrown in occurring 5/17-23 is all but certain by the Ens.

51*(75%RH) here at 6am , thin overcast.        56* by 11am.        Back down to 52* by 1pm.         50* at Midnight.

Morning thoughts...

At 8:15 a few showers were moving through parts of the region. In the Cartland area, some snow was reported. Today will be partly to mostly cloudy with a few showers. It will be unseasonably cool. Temperatures will likely reach the upper 50s and lower 60s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 57°

Newark: 58°

Philadelphia: 60°

Tomorrow will be partly to mostly cloudy. Showers and a period of rain are likely especially late in the day.

The green out there has nothing to do with food (or environmentally wise aspects), it's lawns, non native landscaping and golf courses.
