Across parts of central and upstate New York and central and northern New England, especially the higher elevations, rain will turn to accumulating snow.

bluewave Posted April 14, 2021 Share Posted April 14, 2021 While we are still in a blocky pattern, the warm spots will make a run on 70° today. Looks like several cooler days coming up before the next 70° chance early next week. So some warmer days in the mix even with the -AO +PNA -EPO pattern. Beyond the next 10 days, we would need to see more of a SE Ridge for an 80° chance near the end of April. Still outside the effective range of the guidance. Euro highs today Next run on 70° possible early next week Blocking pattern in the means next 10 days 1 1 Link to comment Share on other sites More sharing options...

CIK62 Posted April 14, 2021 Share Posted April 14, 2021 12Z GEFS claims today was the warmest day we will see for the next 15 days. Mean T goes up 5 degrees during this period so this would be sticker shock. There is a chance for an outburst about the 27th or so. Courtesy of WB.

donsutherland1 Posted April 15, 2021 Share Posted April 15, 2021 Much of the region basked in springlike readings in the upper 60s and lower 70s. However, the next several days will be much colder. A developing storm will likely impact the region tomorrow into Friday. While a cool rain is likely from Philadelphia to New York City, there is the potential for an area of accumulating snow that will run across central and upstate New York State and central and northern New England. The greatest accumulations should be confined to higher elevations. Temperatures will likely stay in the lower 50s in New York City and Newark tomorrow. The latest EPS weeklies notwithstanding, the closing week of April could turn noticeably warmer. Since 1974, there were 7 cases where the MJO reached Phase 6 at an amplitude of 1.500 or above during April 5-15, as was the case this year. Only 1981 had an April 20-30 maximum temperature below 80° (75°). The average highest figure for such cases was 81.3°. Therefore, it is more likely than not that April 2021 will have a maximum monthly temperature of 80° or above. The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was -0.5°C for the week centered around April 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.15°C and the ENSO Region 3.4 anomaly has averaged -0.52°C. La Niña conditions will likely give way to neutral-cool ENSO conditions as the spring progresses. The SOI was -19.69 today. The preliminary Arctic Oscillation (AO) figure was -0.336 today. On April 13 the MJO was in Phase 7 at an amplitude of 1.863(RMM). The April 12-adjusted amplitude was 1.951 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 60% probability that New York City will have a warmer than normal April. April will likely finish with a mean temperature near 54.0° (1.0° above normal). Link to comment Share on other sites More sharing options...
CIK62 Posted April 15, 2021 Share Posted April 15, 2021 The next 8 days are averaging 54degs., (46/62) or about Normal. Month to date is 53.3[+3.0]. Should be about 53.6[+1.8] by the 22nd.

donsutherland1 Posted April 15, 2021 Share Posted April 15, 2021 Morning thoughts... A developing storm will bring rain to the northern Middle Atlantic region to New England. In parts of upstate New York, central and northern New England, colder air working into the deepening storm’s circulation will result in a changeover to snow. A 6”-12” snowfall with some higher amounts is possible in the Berkshire, Green, and White Mountains. However, even Worcester will likely pick up 2”-4” of wet snow with locally higher amounts of around 6” in the vicinity of Worcester. There is a small chance that the precipitation could even change to a period of snow for a time in the Boston area producing a small slushy accumulation. High temperatures will likely reach the middle and upper 50s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 57° Newark: 58° Philadelphia: 63° Tomorrow will be variably cloudy and blustery. Temperatures will gradually increase during the weekend. Link to comment Share on other sites More sharing options...

Would be fitting for it to happen on a late developer bomb on 4/16. These often shift east last minute which benefits them. I’m leaning towards it not happening for Boston but who knows. It can if the setup is right, we got heavy accumulating snow here on 4/10/96, 4/7/03 etc. Guess we’ll find out tomorrow. 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted April 16, 2021 Share Posted April 16, 2021 A developing storm will bring periods of rain to parts of the region overnight, particularly eastern sections. Meanwhile, a snowstorm will rage in the Berkshire, Green and White Mountains. There, 6"-12" of wet snow with locally higher amounts is likely. Worcester will likely pick up 2"-4" of snow. There is an outside chance that Boston could pick up a small accumulation. The last time Boston saw measurable snowfall in April was just last year on April 18, 2020 when 0.7" snow was measured. In the wake of the storm, tomorrow will be variably cloudy and blustery. Temperatures will likely top out in the middle 50s. However, a slow warming trend will likely commence during the weekend. The latest EPS weeklies notwithstanding, the closing week of April could turn noticeably warmer. Since 1974, there were 7 cases where the MJO reached Phase 6 at an amplitude of 1.500 or above during April 5-15, as was the case this year.

donsutherland1 Posted April 16, 2021 Share Posted April 16, 2021 Morning thoughts... A slowly departing storm was bringing snow and rain to parts of New England. Today will start with partly sunny skies, but clouds could increase during the afternoon. High temperatures will likely reach the middle 50s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 55° Newark: 56° Philadelphia: 56° Temperatures will gradually increase during the weekend.
