Thursday looks like a repeat of a few weeks ago when the NAM tried to take the MCS north of us. All the other guidance was further south across our area. So it’s no surprise that we get a nice round of morning convection on the HRRR and RGEM. Maybe we can sneak in a few afternoon 80s with enough clearing.

Nam seems to be all on its own in the drier camp

The RGEM just got a big upgrade in December 2021 while the NAM development was frozen in 2017.

NAM development was frozen after the March 2017 upgrade, and RAP/HRRR development with the WRF-ARW model will cease after the RAPv5/HRRRv4 upgrade in 2020. However, operational execution of these modeling and associated DA systems will continue until comparable FV3-based systems are able to give similar performance.

I saw the point and click…what it forecasted for Suffolk was not this…

While I usually don’t look at the point and clicks, the Euro forecast from yesterday had sunny and 80s for today.

12z Euro Tuesday forecast for today

The weather will remain fairly unsettled into at least the first half of the weekend. Showers and thunderstorms will return and continue into tomorrow morning. Parts of the region could pick up 0.50"-1.50" of rain with some locally higher amounts. Overall, temperatures should remain fairly close to normal. No excessive heat appears likely through the weekend.

Excessive heat will develop in the desert Southwest by tomorrow. Phoenix will very likely see its first 110° or above temperatures of the year. During 1961-90, Phoenix averaged 15.9 110°+ days per year. For the 1991-20 base period, that number has increased to 20.8 days.

During the closing week of May, the MJO moved through Phase 6 with an amplitude as high as 1.909. The only case with an MJO passage through Phase 6 with an amplitude of 1.500 or above during that timeframe was 1998. In 1998, the second half of June was noticeably warmer than the first half. The MJO's ongoing progression and the state of Atlantic blocking could impact the outcome for the second half of June.

The ECMWF seasonal forecast indicates that the summer will be warmer than normal throughout the region and across much of North America. Based on how the pattern has been evolving during the spring transition to summer, it is more likely than not that the warmest anomalies of the summer will likely occur in July and August with June being the coolest of the three months in the Northeast.

The ENSO Region 1+2 anomaly was -0.6°C and the Region 3.4 anomaly was -0.9°C for the week centered around June 1. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.33°C and the ENSO Region 3.4 anomaly has averaged -1.07°C. La Niña conditions will likely persist through the summer.

The SOI was +16.17 today.

The preliminary Arctic Oscillation (AO) was -1.209 today.

On June 6 the MJO was in Phase 8 at an amplitude of 1.858 (RMM). The June 5-adjusted amplitude was 1.945 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 57% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 72.7° (0.7° above normal).

Strongest heat remains to our west through the solstice on the 12z EPS. So we’ll  probably have to wait until late June or July for our first official heatwave with 3 days or more in a row reaching 90°. Last June we had our first heatwave from the 5th to the 9th.

The first heatwave this summer IMO could wait until mid July and we could still end up with over 20 90+ days. In the current pattern we'd only likely get a day or two of heat at the most during June and much of the latest guidance isn't even particularly favorable about that. But I do think we'll probably squeeze out a day or two of 90 in June. But a heatwave before the second week of July at this point just doesn't seem very likely. Of course things can change and the maps (ensembles and operationals) have been changing erratically and will probably continue to do so.

Morning thoughts…

Rain and thunderstorms will come to an end this morning. the sun will return afterward. High temperatures will reach the lower and middle 80s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 80°

Newark: 85°

Philadelphia: 84°

Tomorrow will be partly sunny and pleasant.

Normals:

New York City: 30-Year: 77.8°; 15-Year: 77.8°

Newark: 30-Year: 79.8°; 15-Year: 80.0°

Philadelphia: 30-Year: 81.3°; 15-Year: 81.6°
