The long-term pattern evolution appears quite different from that of 2003. I suspect that this week could offer the last meaningful opportunity for a little snow in and around New York City. Even that is not assured.

The 36” amount was taken by the public. It wasn’t the city’s official measurement. Time: 2021-03-14T21:11:00Z UTC Event: 36.0 HEAVY SNOW Source: PUBLIC

Morning thoughts... At weak system will move eastward across the region. It will be mostly cloudy and cold. A period of light rain or snow is possible in parts of the region, especially during the afternoon or early evening. High temperatures will reach the upper 30s and the lower 40s across most of the region. Likely high temperatures around the region include: New York City (Central Park): 40° Newark: 41° Philadelphia: 43° Tomorrow will be partly cloudy and milder. Overall, the March 16-19 period remains a period of opportunity for at least some snowfall in parts of the region. The next system will be a late-week developing nor’easter that could bring a period of accumulating snow to central and northern New England. A pronounced warming trend will likely commence during the weekend. As a result, there is a chance that the coming weekend could see Central Park’s last freeze of the 2020-21 season.

The March 1-15 period saw New York City come out with a mean temperature of 40.7°. That was 0.7° above normal. The second half of March will likely be warmer relative to normal. A weak system will approach the region overnight and then move across the region tomorrow. As a result, it will become increasingly cloudy tonight. Tomorrow will likely see a period of light snow or flurries, especially during the afternoon into the evening. Any accumulations will likely be minor, as the temperature will likely be well above freezing during much or all of the event. Some areas outside of New York City and Newark could pick up a slushy coating. Following the system, Wednesday will likely see a return to sunshine and milder conditions. Nevertheless, the remainder of the March 16-19 period could still offer some opportunity for at least some snowfall in parts of the region. The coming weekend could mark the start of a new warming trend. Since 1950, nearly 60% of days two weeks after the AO reached +3.000 or above in the March 1-15 period were warmer than when the AO reached +3.000 or above. The AO reached +3.000 on March 10. The mean increase was 2.8°. This suggests that it is more likely than not that the closing week of March could see a return to warmer conditions. Most of the guidance now favors the development of warmer conditions that would continue through the remainder of the month. Wednesday could see greatly elevated CAPE in an area extending from eastern Texas across the Gulf States. As a result, there will likely be a high probability of severe thunderstorms with hail and possible tornados in parts of that area, especially in the Gulf States. That risk of severe weather will then likely move into the Carolinas on Thursday and then offshore afterward. The ENSO Region 1+2 anomaly was +0.9°C and the Region 3.4 anomaly was -0.3°C for the week centered around March 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.20°C and the ENSO Region 3.4 anomaly has averaged -0.80°C. La Niña conditions will likely give way to neutral-cool ENSO conditions as the spring progresses. The SOI was -1.29 today. The preliminary Arctic Oscillation (AO) figure was +1.710 today. On March 14 the MJO data was unavailable. The significant December 16-17 snowstorm during what has been a blocky December suggests that seasonal snowfall prospects have increased especially from north of Philadelphia into southern New England. At New York City, there is a high probability based on historic cases that an additional 20" or more snow will accumulate after December. Since January 1, New York City has picked up 28.1" snow. Winters that saw December receive 10" or more snow, less than 10" in January, and then 10" or more in February in New York City, saw measurable snowfall in March or April in 83% of cases. Winter 2009-2010 was the exception where only a trace of snow was recorded. This group of winters saw 6" or more snow during the March-April period in 50% of the cases. All said, it is more likely than not that there will be measurable snowfall after February. Based on sensitivity analysis applied to the latest guidance, there is an implied 68% probability that New York City will have a warmer than normal March. March will likely finish with a mean temperature near 43.5° (1.0° above normal).

Given the forecast CAPE, I wouldn’t be surprised if the risk is bumped up to “moderate” by tomorrow.

Morning thoughts... In 1990, temperatures rose into the upper 70s and lower 80s across much of the northern Middle Atlantic region. This time around, it will feel more like mid-February than mid-March. At 7 am EDT, temperatures included: Albany: 12°; Allentown: 22°; Binghamton: 12°; Boston: 17°; Bridgeport: 21°; Danbury: 20°; Islip: 22°; New York City: 24°; Newark: 25°; Philadelphia: 28°; Poughkeepsie: 20°; Providence: 18°; and, White Plains: 20°. These will likely be the coldest temperatures the region will see until late next fall. Despite strong sunshine, temperatures will top out only in the upper 30s and the lower 40s across most of the region. Likely high temperatures around the region include: New York City (Central Park): 40° Newark: 42° Philadelphia: 43° Clouds will increase tonight. It will be mostly cloudy and continued cold tomorrow. A period of light snow could impact the region. Overall, the March 16-19 period remains a period of opportunity for at least some snowfall in parts of the region. A pronounced warming trend could commence during the weekend.

Cheyenne has seen 22.2” snow today. The 22.2” daily snowfall beats the old daily record of 19.8”, which was set on November 20, 1979. The 30.3” storm total surpasses the 25.6” that fell during November 19-21, 1979 to become Cheyenne’s biggest snowstorm on record.

Tomorrow will be the coldest day of the week and possibly the coldest day until at least late next fall. Temperatures will tumble into the lower and middle 20s from Philadelphia to New York City and into the teens in some areas outside of those cities. This cold shot following the recent warmth is not unusual. Since 1990, 73% of cases that saw a high temperature of 70° or above during March 1-15 were followed by a low temperature of 32° or below during the following two weeks. 54% of such cases saw a low temperature below 30° during the following two weeks and 27% saw the temperature fall below 25°. The mean lowest temperature during the following two weeks was 29°. In addition, the March 16-19 period could offer a period of opportunity for a light snow event in parts of the region. Next weekend could mark the start of a new warming trend. Since 1950, nearly 60% of days two weeks after the AO reached +3.000 or above in the March 1-15 period were warmer than when the AO reached +3.000 or above. The AO reached +3.000 on March 10. The mean increase was 2.8°. This suggests that it is more likely than not that the closing week of March could see a return to warmer conditions. Out west, a major to historic blizzard will continue into late tonight or early tomorrow. Cheyenne will likely set its all-time storm total snowfall record. Cheyenne's All-Time Snowfall Records: Daily: 19.8”, November 20, 1979; 2-Day: 25.2”, November 20-21, 1979; 3-Day: 25.6”, November 19-21, 1979 The ENSO Region 1+2 anomaly was +0.2°C and the Region 3.4 anomaly was -0.7°C for the week centered around March 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.43°C and the ENSO Region 3.4 anomaly has averaged -0.87°C. La Niña conditions will likely prevail at least through most of March. Afterward, neutral-cool ENSO conditions will likely develop as the spring progresses. The SOI was -2.44 today. The SOI had recently been negative for 10 consecutive days. That development could be an early indication that what has been a fairly stable La Niña regime throughout the winter could be moving closer to its end stages. The preliminary Arctic Oscillation (AO) figure was +4.329 today. On March 13 the MJO data was unavailable. The significant December 16-17 snowstorm during what has been a blocky December suggests that seasonal snowfall prospects have increased especially from north of Philadelphia into southern New England.

313 FXUS65 KCYS 142257 AFDCYS Area Forecast Discussion National Weather Service Cheyenne WY 457 PM MDT Sun Mar 14 2021 .SHORT TERM...(Tonight - Monday) Issued at 352 PM MDT Sun Mar 14 2021 ...HISTORIC AND CRIPPLING BLIZZARD SEVERELY IMPACTING TRAVEL AND COMMERCE ACROSS MUCH OF THE AREA... Extreme snowfall. Whiteout conditions. Severe drifting. Impossible travel. This epic winter storm & blizzard has truly become one for the record books, literally. A storm total snowfall of 25.8 inches was recorded at NWS Cheyenne as of the 12 PM MDT observation, with periods of moderate to heavy snow continuing through the afternoon hours. This already shatters our 2-day record, and could even near or exceed 30 inches by the time all is said and done. Snow amounts upwards of 4 feet have been reported in some of the higher terrain along the Laramie Range! Very impressive indeed. Extreme snow fall rates of 2-3 inches were common through the event with a number of instances of thunder snow as a highly anomalous fetch of moist and unstable air interacted orographically with the Cheyenne Ridge and the Southern/Central Laramie Range. 10 inches of snow fell in a 4- hour period ending at 7 AM MDT this morning! That would be a solid snowfall event just in itself, but extreme rates persisted through the morning with widespread totals reaching 2-3 feet along/east of the Laramie Range as an extremely impressive TROWAL wrapped across the CWA in the presence of deep upslope. Surface cyclogenesis over Colorado led to tightening MSLP gradients, and widespread blizzard conditions as wind gusts up to 50 MPH plagued the area for most of the early morning and afternoon hours. Drifts became impressive at 5-10 feet and WYDOT has reported via Twitter that rotary plows are needed to clear portions of I-80. Perspective: This is the type of equipment normally used to clear mountain passes in the Spring. It is virtually impossible to travel, and could remain very difficult for the next day or two as the degree of drifting is unprecedented on this scale. This is even considering that snow and wind impacts should diminish this evening and overnight. Spectacular Water Vapor Satellite display with an extremely large/ intense upper-level low spinning over east central CO w/ quite the footprint encompassing over half of the CONUS. Expect this record- breaking system will begin to fill shortly as it drifts off to the east-northeast, but wrap-around moisture should support periods of snow through Monday morning, although any additional accumulations should be limited. Direct impacts from snow and blowing snow could lessen considerably in the next few hours, but it will take a good bit of time to dig out. .LONG TERM...(Tuesday - Sunday) Issued at 332 AM MDT Sun Mar 14 2021 A very active pattern in store for Tuesday to Wednesday evening as we have a quick succession of this current winter storm lifting northeast, followed by a closed low moving south across the Four Corners region, and finally a shortwave embedded in the eastern side of a ridge that builds into SE Wyoming and W Nebraska Thursday. Once the ridge builds in Thursday, skies should clear and temperatures will warm up to above normal once again. But, until then, there are chances of precipitation across most of SE Wyoming and W Nebraska, most likely snow as our temperatures will be in the 20s at night, only warming up the lower-to-mid 30s during the day. Accumulations were previously forecast to be between 1 and 3 inches, but now with the latest model runs, it's looking closer to an inch or less with higher amounts in the mountains and higher elevations. The center of the low stays well south of forecast region and it moves very quickly eastward and northeastward, but as it interacts with the current major winter storm, the low stalls the winter storm, keeping the snow and some minor impacts around until Wednesday afternoon/evening when both systems are pushed out of the way by a strong ridge. Another reason this small second wave is less likely to drop buckets of snow on Wyoming and Nebraska again is because as the winter storm moves northeast, it puts Wyoming and Nebraska on the southeast side of the storm where the winds are westerly, which is downsloping for most of our forecast area and limits the growth of the snow showers. &&

It can happen. I saw it once when I was west of Trois Rivières in Canada.

Thank you, Jake. Enjoy the snowstorm. It’s an exceptional one.

It's an amazing storm. Also, would you mind if I add your photo to my winter storms photos site.

There was a sprinkle in New Rochelle, NY a short time ago.

Back on March 5 0z, the EPS ensembles were indicating that there would be a pattern similar to that of March 9-15, 2020. https://www.americanwx.com/bb/topic/54600-march-2021/?do=findComment&comment=5954517March 9-12, 2021 saw what turned out to be an even more amplified version of the 2020 pattern, as the Arctic Oscillation (AO) soared to a preliminary March record of +5.656. As a result, the March 9-12, 2021 timeframe was even warmer than the March 9-15, 2020 period.

NWS Cheyenne: 10” snow in 4 hours. https://twitter.com/NWSCheyenne/status/1371082592682790914?s=20

Morning thoughts... A blizzard is currently bringing heavy snow and high winds to parts of the Rockies. So far, Denver has picked up 11.1” of snow. Areas around Cheyenne had picked up 8” of snow just before midnight MST. A strong cold front will cross the region today. Overall, it will be partly sunny and increasingly windy. Winds could gust past 50 mph in some areas. There could be an isolated sprinkle. Temperatures will likely top out mainly in the upper 40s and lower 50s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 53° Newark: 55° Philadelphia: 58° Tomorrow will be sunny and unseasonably cold. Much of the region will see low temperatures in the lower 20s. Outside the major cities, some teens are possible. The March 16-19 period could still offer a period of opportunity for a light snow event in parts of the region. Out west, the major to perhaps historic snowstorm will rage into this evening. Snow will diminish at night or early tomorrow. Denver will likely experience a storm total 12”-18” snowfall. Cheyenne remains on track to pick up a storm total 20”-30” of snow. Cheyenne’s March Snowfall Records: Daily: 15.9”, March 18, 2003; 2-Day: 17.2”, March 17-18, 2003; 3-Day: 18.9”, March 5-7, 1990 Cheyenne’s All-Time Snowfall Records: Daily: 19.8”, November 20, 1979; 2-Day: 25.2”, November 20-21, 1979; 3-Day: 25.6”, November 19-21, 1979

Cooler weather moved back into the region overnight. Tomorrow will be partly sunny, windy, and seasonably cool. A strong cold front will move across the region bringing some clouds. There could be an isolated sprinkle. Monday will be the coldest day of the week and possibly the coldest day until at least late next fall. Since 1990, 73% of cases that saw a high temperature of 70° or above during March 1-15 were followed by a low temperature of 32° or below during the following two weeks. 54% of such cases saw a low temperature below 30° during the following two weeks and 27% saw the temperature fall below 25°. The mean lowest temperature during the following two weeks was 29°. Monday's fairly strong cold shot is consistent with recent historical experience. In addition, the March 16-19 period could offer a period of opportunity for a light snow event in parts of the region. Next weekend could mark the start of a new warming trend. Since 1950, nearly 60% of days two weeks after the AO reached +3.000 or above in the March 1-15 period were warmer than when the AO reached +3.000 or above. The AO reached +3.000 on March 10. The mean increase was 2.8°. This suggests that it is more likely than not that the closing week of March could see a return to warmer conditions. Out west, a major to perhaps historic snowstorm will continue into late tomorrow or early Monday. Denver, Cheyenne, and possibly Casper, as well as the Nebraska Panhandle, will likely see heavy snowfall. Denver will likely pick up 8"-16" of snow. Cheyenne will likely see 20"-30" of snow. That would set a new March record and could challenge that Cheyenne's all-time record snowstorm amount. Cheyenne's March Snowfall Records: Daily: 15.9”, March 18, 2003; 2-Day: 17.2”, March 17-18, 2003; 3-Day: 18.9”, March 5-7, 1990 Cheyenne's All-Time Snowfall Records: Daily: 19.8”, November 20, 1979; 2-Day: 25.2”, November 20-21, 1979; 3-Day: 25.6”, November 19-21, 1979 The ENSO Region 1+2 anomaly was +0.2°C and the Region 3.4 anomaly was -0.7°C for the week centered around March 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.43°C and the ENSO Region 3.4 anomaly has averaged -0.87°C. La Niña conditions will likely prevail at least through most of March. Afterward, neutral-cool ENSO conditions will likely develop as the spring progresses. The SOI was -11.68 today. The SOI had recently been negative for 10 consecutive days. That development could be an early indication that what has been a fairly stable La Niña regime throughout the winter could be moving closer to its end stages. The preliminary Arctic Oscillation (AO) figure was +4.329 today. On March 12 MJO data was not available. The March 11-adjusted amplitude was 1.297 (RMM). The significant December 16-17 snowstorm during what has been a blocky December suggests that seasonal snowfall prospects have increased especially from north of Philadelphia into southern New England. At New York City, there is a high probability based on historic cases that an additional 20" or more snow will accumulate after December. Since January 1, New York City has picked up 28.1" snow. Winters that saw December receive 10" or more snow, less than 10" in January, and then 10" or more in February in New York City, saw measurable snowfall in March or April in 83% of cases. Winter 2009-2010 was the exception where only a trace of snow was recorded. This group of winters saw 6" or more snow during the March-April period in 50% of the cases. All said, it is more likely than not that there will be measurable snowfall after February. Based on sensitivity analysis applied to the latest guidance, there is an implied 52% probability that New York City will have a warmer than normal March. March will likely finish with a mean temperature near 42.9° (0.4° above normal).

Under bright sunshine, the temperature rose to 50° in New York City. After the last few days of much above normal temperatures, the New York Botanical Garden’s Japanese Apricot trees have burst into bloom. Crocuses are out in abundance.

Morning thoughts... Overnight, cooler air began pushing into the region on gusty winds. Nevertheless, New York City’s Central Park set a record high minimum temperature for March 12 with a low temperature of 52°. That beat the previous record of 50°, which had been set way back in 1898. Today will be fair, windy and noticeably cooler than yesterday. Temperatures will likely top out mainly in the upper 40s and lower 50s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 49° Newark: 50° Philadelphia: 52° Tomorrow will be a seasonably cool day. The March 16-19 period could offer a period of opportunity for a light snow event in parts of the region. Out west, a major to perhaps historic snowstorm will get underway and continue through late tomorrow night or early Monday. Denver will likely experience an 8”-16” snowfall. Cheyenne remains on track to pick up 20”-30” of snow. March Snowfall Records: Daily: 15.9”, March 18, 2003; 2-Day: 17.2”, March 17-18, 2003; 3-Day: 18.9”, March 5-7, 1990 All-Time Snowfall Records: Daily: 19.8”, November 20, 1979; 2-Day: 25.2”, November 20-21, 1979; 3-Day: 25.6”, November 19-21, 1979

Enjoy the storm.
