April 2022

[bluewave]

Yesterday was our  driest day of the year with the relative humidity dropping to 10%. So quite a shift from the record rainfall around the area in recent weeks. The drier ending to April  prevented parts of the area from recording another 10.00” month.

It was a top 5 wettest April west of NYC where the best training set up.

 

[LoboLeader1]

Reached 55 here yesterday, overnight low was 44. Currently 47 as of 9AM.

[BucksCO_PA]

25 degrees at Somerville this morning.

Locally 30-32 degrees for locations with no wind.

For nearby TTN this month will represent the 3rd below average April over the past 5 yrs. During that time frame the average April temp is down 3 degrees from the  prior 2010-2017 period.

Somerville station is 5 miles from me, and I was 36.  Big difference.

I love this lowering of water vapor the last couple of springs, my allergies are gone and I can breathe normally again

we need water vapor reduction as well as carbon dioxide reduction both are greenhouse gases and both are pollutants.

I hope we can develop devices to get rid of both excess water vapor and excess carbon dioxide, the air feels so much cleaner without these pollutants.

Good morning BW. An amazing graphic. If this reflected the precipitation amounts after an extremely cold January, It would qualify as the final exam for the weather forums Coastal Plain anger management course. As always ….

NE PA and NW NJ did much better with April rainfall than they did with seasonal snowfall.

Humidity is already showing sub-20 % in parts of NJ.  Let's see if anyone reaches the single digits this afternoon.

I know we've talked about this many times but that CPK figure is approx. 1.5-2 inches below what it should be. Not a huge error but material nonetheless.

61/3 at ewr.  Humidity 9%!

Relative humidity down to 9% at Newark with the dew point getting close to 0. This is the 2nd April in a row with the relative humidity dropping below 10%.

There are such devices.  A company wanted to build a plant in Linden NJ, collect the CO2, and invite neighboring power plants to collectively pipe the CO2 to underground caverns offshore.  Then, Gov. Christie, nixed the deal.  Sounded pretty far fetched, but I believe there might be a similar, but smaller scale operation in the North Atlantic, somewhere between the British Iles and Norway?

The weekend will be several degrees warmer than today. However, the cooler than normal weather will likely persist through Tuesday on account of the ongoing blocking. Then, there could be a short-lived rebound in temperatures before cooler air returns.

During the 1991-2020 period, the April 25-May 5 period saw temperatures average 1°-2° below normal when strong blocking coincided with Niña conditions, as has been the case this year. Afterward, approximately 50% of such cases went on to see a warmer to much warmer than normal second half of May. The end result will likely be a warmer than normal May when the month concludes.

The ENSO Region 1+2 anomaly was -1.9°C and the Region 3.4 anomaly was -1.0°C for the week centered around April 20. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.98°C and the ENSO Region 3.4 anomaly has averaged -0.92°C. La Niña conditions will likely persist into the start of June.

The SOI was +15.72 today.

The preliminary Arctic Oscillation (AO) was -1.033 today.

On April 27 the MJO was in Phase 3 at an amplitude of 0.624 (RMM). The April 26-adjusted amplitude was 0.540 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a cooler than normal April (1991-2020 normal). April will likely finish with a mean temperature near 52.7° (1.0° below normal).

Yes I remember this happened last year too and that's when my allergies stopped then too

The last day of April is averaging 56degs.(45/66) or -1.

April to date is averaging 52.6[-0.9].      April will end at 52.7[-1.0].

Year To Date will be  -19/120 or -0.16.

GFS is rainy/cloudy from Monday thru Saturday next week.      Could mostly go by to our south.

The first 10 days of May are averaging 56degs.(48/63) or -4.

Reached 65 here yesterday with a RH of 23%.

Today: 62-66, wind n., m. clear, 49 tomorrow AM.

47*(34%RH) here at 7am.      50* at 9am.       57*(27%RH) here at Noon.        63*(24%RH) at 3pm.        66*(23%RH) at 4pm.          Reached 67* at 4:15pm.       59*(47%RH!) at 5pm.        53* at 10pm.

A split departure month around the area. NYC and LGA were closer to -1  and the others are near normal for April. New England was warmer than average.

EWR…..+0.1

NYC…..-0.9

LGA……-1.3

JFK……+0.1

ISP……..+0.3

Morning thoughts…

It will be partly sunny to mostly sunny and a bit milder. High temperatures will likely reach the lower 60s in much of the region. Likely high temperatures around the region include:

New York City (Central Park): 66°

Newark: 67°

Philadelphia: 68°

Below normal temperatures will persist through the middle of the first week of May.

Normals:

New York City: 30-Year: 67.3°; 15-Year: 67.8°

Newark: 30-Year: 68.1°; 15-Year: 68.7°

Philadelphia: 30-Year: 70.0°; 15-Year: 70.5°

[MJO812]

48 here

[Rtd208]

Beautiful day out there today.

Current temp is 66 here.

[winterwx21]

Up to 71 degrees here now and not a cloud in the sky. Absolutely perfect spring weather.

[Snowlover11]

top 10 day.  absolutely beautiful outside with a light breeze 

[LoboLeader1]

A very comfortable 65 here as of 5PM, great day to be outdoors.

A cool April is concluding. At New York City, the monthly mean temperature was 52.8°, which was 0.9° below normal.

Tomorrow will be another partly sunny and pleasant day. However, the generally cooler than normal weather will likely persist through Tuesday on account of the ongoing blocking. Then, there could be a short-lived rebound in temperatures before cooler air returns for a time.

During the 1991-2020 period, the April 25-May 5 period saw temperatures average 1°-2° below normal when strong blocking coincided with Niña conditions, as has been the case this year. Afterward, approximately 50% of such cases went on to see a warmer to much warmer than normal second half of May. The end result will likely be a warmer than normal May when the month concludes.

The ENSO Region 1+2 anomaly was -1.9°C and the Region 3.4 anomaly was -1.0°C for the week centered around April 20. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.98°C and the ENSO Region 3.4 anomaly has averaged -0.92°C. La Niña conditions will likely persist into the start of June.

The SOI was +6.49 today.

The preliminary Arctic Oscillation (AO) was -0.731 today.

On April 28 the MJO was in Phase 3 at an amplitude of 0.772 (RMM). The April 27-adjusted amplitude was 0.624 (RMM).

I hope the weather is as great as this for the total lunar eclipse in 2 weeks
