  1. Time for the annual seasonal forecast contest ... same simplified format, just predict the seasonal counts of Storms, Hurricanes and Major Hurricanes, the long-term average for the sake of the format is 16/8/3 (or thereabouts). The contest will be based on the official NHC reporting on these stats during the season. Whether a named storm appears in May or not, the contest will not be affected, your prediction is the season end total, not the remainder of the season total. I will say June 1st as a rough deadline but may extend it slightly if there is a need to attract more entries. In past years 20 to 30 entries have been posted. Good luck!
  2. Day late getting to this ... anomalies and projections ... ___________________________ DCA _NYC _BOS __ ORD _ATL _IAH ___ DEN _PHX _SEA 12th ___ (11d anom) ______ -4.3 _-3.5 _-3.9e __+0.5 _+2.4 _+6.2 __ +2.0 _+2.5 _-5.5 12th ___ (p21d anom) ____ -2.0 _-2.0 _-2.0 ___+3.5 _+3.0 _+5.0 __ +2.0 _+2.5 _-4.5 12th ___ (p28d anom) ____ -1.0 _-1.0 _-1.0 ___ +2.5 _+2.5 _+4.0 __ +2.0 _+2.5 _-3.5 _______ (11th) _ The very warm air mass now covering central U.S. states will probably modify back towards more average anomalies as it slowly works its way east and mixes in with a cooler variant left over from a coastal nor'easter. The result will likely be a slow moderation of current large negative anomalies in the east and continued warming for central locations, with an interruption expected in a few days. Western locations will stay fairly similar to current anomaly pattern with very cool air over the Pac NW only gradually relenting slightly. A hurricane depicted in the GOM near end of the model run could bring anomalies down at IAH if it comes ashore around there. Otherwise it looks like quite a warm month for IAH. No new snowfalls noted, most recent updates are in April thread.

  4. Even so, there wasn't a lot of range in the scores and while the ranks have moved around a bit, everyone is pretty close together in the pack. I gave away a lot of points on IAH after scooping a lot everywhere else. But by my standards it was a big month, I didn't fall further behind.

DonSutherland1 advanced from 6th to 2nd, while wxallannj remained 3rd, and Tom moved from 5th to 4th, with so_whats_happening now in 5th and hudsonvalley21 now 8th as RodneyS moved from 8th to 6th. BKViking remains in 7th to 8th. RJay moved from 10th to 9th, exchanging positions with Scotty Lightning now 10th. Consensus moved into sole possession of 3rd (had been tied 4th last month).

  7. Predict the temperature anomalies (F deg) relative to 1991-2020 averages for DCA _ NYC _ BOS __ ORD _ ATL _ IAH ___ DEN _ PHX _ SEA Contest deadline for on-time entries 06z Sunday May 1st. Late penalties apply thereafter. There will be a summer seaonal max contest added to the June contest thread. Good luck.
  8. For the four pirmary airport locations, DCA, IAD, BWI, RIC, predict the highest temperature to be recorded in the (extended) summer of 2022. Deadline for entries will be end of the day May 31, 2022. Edited revisions can be made to your earlier posts without notice as I will not record any forecasts until June 1st. Contest is based on lowest accumulated departure from actual, and ties are settled by the lower maximum error applied sequentially until a result is obtained. For example, two forecasters might share a total error of 5 from (2, 2, 1, 0) and (2, 1, 1, 1). The first check on tiebreaker is a "pass" (2) so then the three remaining numbers are compared and (1,1,1) beats (2,1,0). Two identical forecasts that cannot be separated will rank in order of earlier forecast submitted. Good luck, I will post some info on defending champs from previous two or three years, I know this is at least the third go for this contest, could be the fourth, will have to look back and see. Please use this order to post forecasts although I will check to make sure my tables reflect your actual order.

  9. Final scoring for April 2022 SEA required adjusted scoring as top raw score was 56. Most of the changes are small as the progression overlapped the raw scores most of the way. Scores marked ^ are adjusted to fit the progression. The lower half of the scores were higher (or same) on raw score than progression.

  10. That's good to know. Just out of interest, what are the latest measurable snowfall dates for the four airports? I think it would be last week of April for NYC and middle of May for Toronto so I am guessing maybe around now to 20th? Also last traces would be interesting to know. Those are about 2-3 weeks later for the places for which I have stats -- there was a trace of snow in Toronto last May 29th and the absolute latest is June 3rd. NYC is May 9th (2020 tied 1977).

Colder air is moving south again but mostly into central and western regions with just leftover cool temperatures expected to reach the northeastern states. Past the immediate outlook period a more average sort of regime is indicated. There are a few minor changes to seasonal snowfall totals -- 32.6" ORD, 44.8" DTW, 95.3" BUF which will be incorporated into the table still over in the March thread. That will migrate over to this thread eventually. The snowfall season may have a bit left to give in a few locations, by the looks of recent model runs. 21st _ Trends continue up and down but rather cold in ORD and very cold for SEA (and here, we currently have light snow and a balmy 1 p.m. temp of 35F). Additional snow 0.2" ORD to 32.8", DTW 2.3" to 47.1", BUF 0.7" to 96.0" and BTV 4.2" to 70.7" with all others incl DEN no measurable new snow, some traces. Changes will be made to the contest scoring table located in the March thread. The table will be migrating over to this thread at end of April. The contest is not settled as further snow at DEN or other locations could change the order of finish. The measurable snow season lasts through May at some locations. Projections to end of month based on balancing warm and cold spells next ten days in east, continued warmth in PHX and continued current trends in DEN and SEA. Will post some preliminary scoring based on these estimates. 28th _ Tweaked the end of month projections, some have changed a bit, others were okay. BUF had 1.4" more snow on the 27th, waiting for this cold spell to end to update the tables and bring them over to here at end of April. No other new snow reported as of end of 27th. 30th _ Posting end of month estimates that has been edited to completion overnight into May 1st. Also, snowfall contest update has been added to scoring table.

  13. Record Low Maxima, Minima by Years _ NYC The intention was to add logs of record low temperatures to the annual summaries for NYC, but editing those already long posts seems to be straining the pagination to the extent that I can't be very confident that the posts will edit without freezing up or corrupting the information already in the posts. So with the addition of a disclaimer in the 1869 annual summary, here's what will happen to fill in the details ... for 1869 to 1900 (the starter era for records), the daily max and high min are already posted, so I need to post only the low max and min data for those years. Starting in 1901, only the high max are logged, high min and the low max, min will all be required. The first post here will detail the minimum values for 1869 to 1900, showing the records established in the starter era and then what happened to them, if anything (a lot of them survive to the end of data because the urban heat island was weakest in these decades, and it was a cold climatic era). The cold records often occur together (low max, low min) either on the same day or adjacent days so the tables will be arranged to show these groupings. In all of the following, ER will mean eventual record. If the record set is later tied, that will show as ER (t 1940) etc. All counts of records include 0.5 counts for ties (or 0.333, 0.25, 0.2, 0.167 etc depending on number of ties, there is one low minimum that was tied six times). For starter era records set, that includes ties within the starter era only. For eventual records retained, that includes ties in later years so that if for example a record was set in 1871 and tied in 1893, those two years would be credited with 0.5 originally set records each, and if the record held up but was tied twice more, then they would each be credited 0.25 for eventual records as well as the other two years (which would count 0.33 and 0.25 when they joined the tied grouping for originally set records). The count in the starter era should be interpreted as the count as of end of 1900, obviously the first set of tied records stood alone until tied. However, since this was a starter set, it would not have been too obvious at first what the range of eventual records might look like. By 1900 this was fairly clear. In fact, the average starter low max is only 1.95 F deg higher than the eventual record, so quite a few of them have survived. Any temperatures shown in the tables for low max or low min in brackets are not daily records but are shown to illustrate the range of temperatures associated with the reading that is a record low. The more extreme of days before or after the actual record are used, where applicable, and the date selected is shown when the non-record is not on the same date as the record value shown. (e.g., record low 31 F on Nov 7, 1869, before a low max of 39F on Nov 8th which was not a record; the max on 7th was 43F not shown). This approach may be skipped if the value that would be selected appears anyway for a subsequent or previous date, then a less impressive actual daily associated reading may appear (e.g. Oct 26, 1869, max 47F before record low max next day). Dates that set records for both low max and low min are shown indented and the low max information appears in the first of the two rows of data, the low min in the second row. Note that the expected number of starter year records of each type at random is 11.4 (365/32 or 366/32). The expected number of surviving records is 2.4 (366/153.2). Since this was generally a colder climate era, the average number of surviving records is more than twice the numbers expected for low max and low min. 1869 _ The year set 17.17 starter record low maxima, and 8.5 starter record low minima. Of those, 6.83 and 4.0 have survived to the end of data.

spells until October, then started to make up its deficit with very cold October and December setting the majority of the records. The two low max records before October were both fairly weak and pushed aside in the 1920s. There were 8.5 record low maxima of which 5.5 have survived, and a count of 12.25 record low minima of which 6 have survived. The second instances in the record log of a "coldest since" a low minimum record were on Apr 30 (34F coldest after the 1874 record of 32F) and Dec 2 when 11F from 1875 was followed in 1876 by a reading of 15F that was later tied in 1886 (for "coldest since"). That made the count for 1876 1.5 for this statistic -- the "coldest since" stat is helpful later on in the urban heat island and warmer climate era, to get a better idea of the cold potential of various more recent years. These very early "coldest since" markers are rare due to the frequency of cold years following (until the 1920s at least).

Jan 24th with a low maximum of 6F is the coldest such reading in January although December has had lower values. (Also it is probable that Jan 22, 1857 was colder). Mid-May and early December were the coldest parts of the year relative to normal. There was also one "coldest since" reading in 1882, on Nov 6th when a low of 30F (later tied in 1953) was coldest since the record of 27F set in 1879. It was also 31F on that date in 2012 which probably indicates a structurally colder air mass given the strength of the urban heat island at the various times of previous records.

Mid-July was exceptionally cool. But the year only generated 3.5 record low maxima and none of them have survived. From 7.67 record low minima, 6.0 have survived. This suggests that 1890 was taking advantage of the weak urban heat island to score durable records by radiational cooling in fairly marginal air masses by modern standards. There were no "coldest since" low minimum records set. The extinction date for 1890 low maxima was Aug 24, 1937. This is earlier than any of the other years that had record low maxima and failed to retain any. Before 1890 became the first extinct year in this regard, 1936 became the first year not to record any record low minima, followed by 1939. The next extinction for a year with records was in 1940 (for 1908). Thus by 1940, four years had no record low maxima (1890, 1908, 1936 and 1939).

From 13.33 low maximum records set in the starter era, 7.7 have been retained, and surprisingly this is the highest number for any year after 1888. Within the starter era, 1894 ranks 13th of 32 for starter records set and also falls behind 1903 so is 14th overall, but ranks 7th for those that have survived (and therefore is seventh overall since no years surpassed it afterwards). For low minima, 1894 had 10.17 in the starter era and of those only 2.5 survived. The coldest part of the year relative to normal appears to be July but the various records are sprinkled through the entire year, and in addition, there are three "coldest since" record low minima, with a count of 2.5, these being Feb 24th (2F the lowest minimum after the -1F record set in 1873), June 7th (48F was coldest after record of 47F in 1879) and July 10th (56F coldest after 1890 record of 55F which prevented this from being the fourth consecutive daily record set (only one of the other three survives today, see table below).

The high points were similar, namely May, September and December. February of 1895 was notably cold, and there were some chilly days in mid-summer despite some all-time records for heat set at either end of the summer. Out of 6.5 low maxima set, 2.5 have survived.

The summer remained quite warm, and the autumn was then more variable but had several occasions where lowest temperatures were 1 to 3 degrees outside record range. The overall count was fairly low for the starter era with 5.83 low maxima (3.0 surviving) and 6.5 low minima (3.0 also still remain).

This was reduced from 178.5 as recently as March 28th of 2022 (1893 lost a record to 2022). So that means that almost half the days of the calendar year have a low maximum at least tied if not outright owned by a starter year. The count for low minima is 149.2, which means that about 40% of all days have a record low minimum from the starter era. The next sets of tables will document how the remaining years changed various starter era records.

(in March, four shared a win for DCA shown by ^ -- this counts as 0.25 in the second bracketed total). (wins for Normal are in addition to forecaster wins and do not replace them) So far, 17 of 27 forecasts qualify, 6 warmest and 11 coldest; Jan 0-5, Feb 4-4, Mar 2-2.
