Well anyway it's now 101 F at SEA, case closed (ended up 102). (104 Sunday all time SEA record) (105 hourly 3 pm Monday, could be 106 for the max?) 108 where I live, probably also all-time record or close to it.

101F at Sea-Tac at 4 pm PDT .. is that all-time for SEA? I can remember it hitting maybe 99 or 100 a few years ago. 104F at PDX and 109F at The Dalles (which is a heat trap but still ... ) also 104F at YKA (Kamloops) which is not often within 1-2 of the heat trap locations. (to be fair, you couldn't design a better heat trap than the Fraser canyon, it points due south, it has bare rocky surfaces and the weather stations are at airports on south-facing benches, nobody in their right mind would live right there anyway). The full effects are not quite into the normal hot spots of southeast WA and eastern OR which are in the low 100s, sometimes those places like Walla Walla, Pasco and Pendleton can get into the low 110s. Probably will tomorrow.

This early onset is certainly the main feature, Don, we often count on a cloudy and unsettled June to keep the wildfire situation under control and in most years the weather gradually dries out and warms up through July in this northern extension of the interior west, so breaking all-time June records will be child's play for this late July heat wave. It ,may end up breaking the July records too. The Fraser valley region east of Vancouver has 38-39 C readings and the dew points are oppressive for this climate, around 18 or 19 C, adding some discomfort to the humidex values. That is a heavily populated region so it's not just 100 and something in a desert with tumbleweed and a couple of houses beside a dried out lake, we're talking about millions of people between greater Vancouver and Sea-Tac taking on this 100-degree heat without much a/c and generally not all that used to it (although it does seem to happen every other year now). Also you would think there's a lot of places to go to cool off at a beach, but in a lot of places beach access is very limited around these regions, the shoreline tends to be either lined with cottages or swamp where you can't swim. And inland lakes are very small and fill up with day users very quickly. The current temperature at YVR (Vancouver Int'l A) is only 30 C (86 F) but it's probably closer to 35 C in most of the urban areas around Vancouver, the airport is very close to the sea and almost always has a seabreeze during heat waves. The all-time record there from late July 2009 is only 35 C.

Posted this in the other discussion not realizing this thread had been opened up, so the info is more relevant here than there ... We are under the heat dome big-time now, in southern BC as well as the Pac NW region. For BC, the all-time record highs are 44.4 C (recorded as 112 F) in July 1941 at locations in the Fraser canyon region about 150 miles northeast of Vancouver. Numerous other inland locations have recorded extremes between 42 C and that value, a few of them since we converted from F to C in the late 1970s. Canada's all-time high is just one F deg higher (113F which is 45.0 C) and that was in July 1937 in towns southeast of Regina SK. In both the 1936 and 1937 heat waves, numerous 42-44 C readings were registered and the all-time warmest top thirty (available on wikipedia) is dominated by these three events (1936, 1937, 1941) despite the warming trends recently. For whatever reason Canada has not seen any new extremes, a couple of times around 2003 and 2009 there were 42C readings. Toronto has about a dozen days with 100+ readings, the hottest were in 1936 (three at 105F) and almost all the rest between 1911 and 1953. Only 2011 contributed one to this list after 1953. There has been an increase in mean temperature at Toronto but almost all of it is with overnight lows, not daytime highs (compared to the mid-20th century, obviously all parameters increased from late 19th to early-mid 20th). This current heat wave appears capable of approaching those all-time record highs, will report back on the results. We are right under the heart of this 500 mb heat dome (shown at 599 dm) in south-central BC this weekend. I live about halfway up the west side of the Columbia valley where the base elevation is about 400m asl and the local peaks in the Monashee range are around 2000-2500m. My local elevation is about 1050m. The nearest reporting station (Warfield BC) is at about 700m. It can be one of the province's hottest reporting sites, Osoyoos near the US border in the Okanagan and Lytton or Lillooet in the Fraser canyon are more frequently tops. We weren't quite under the full effect of this on Friday but already it was 36 C (97 F) at Warfield. Expecting closer to 40 C today and the peak likely around Monday-Tuesday. (since I typed that two hours ago it has hit 41 C at Lytton BC, I also see 107F at The Dalles east of Portland OR, and numerous low 100s in WA state. About 38C or 100F at my place. This heat wave looks like it might more or less match the July 1941 event but this one has appeared earlier, one has to wonder if there could be a more severe event later in the summer). A/C is not all that common in our part of the world despite the fact that almost every summer there are a few sweltering days. It does tend to cool off fairly well at night here, I was out at midnight admiring the rising moon near Saturn, and it was quite comfortable, probably about 65F. If you have clear skies where you live tonight, have a look between midnight and 0200h local time, you'll see the Moon very close to Saturn and then Jupiter off to the left rising a bit later. The Moon will then be close to Jupiter on Sunday night.

By the consensus or the max forecast? It is super hot out this way right now, all SEA is going to need to break 100 is a land breeze. Highs in the 105-110 range are going to be widespread in the Pac NW and s BC this weekend and most of the following week. I am at nearly 4,000' elevation but right now it's close to 98F and heading for the 103-105 range. Valleys will be hotter. But SEA can hold on to a weak seabreeze, right now I see it is 88 there with a northerly breeze. Probably tops out at 95 today, maybe higher in coming days.

Final scoring for June 2021 Scores are based on the latest projections in the previous post, anomaly tracker. When the highest raw score is below 60, we go to a system of progressive scoring with a max of 60. With eleven forecasts, that gives levels of 0, 6, 12, 18 ... 54, 60. No "minimum progression" score is used where the raw score would be higher. Minimum progression scores are marked ^.... same score either way * Minimum progression was needed for most of the BOS scores, and the top two SEA scores, otherwise SEA scoring was higher or equal for raw scores below the 48 level. DEN and PHX made late exits from minimum progression. That has not been shown in the scoring table yet, waiting for the actual numbers to save a step. ___________________________ FORECASTER ________DCA_NYC_BOS_east_ ORD_ATL_IAH_cent __ c/e __ DEN_PHX_SEA_west _ TOTAL Roger Smith __________ 84 _ 80 _ 17 __ 181 __ 66 _ 70 _ 98 __ 234 _ 415 __ 88 _ 58 _ 48*__ 194 ___ 609 BKViking _____________ 68 _ 96 _ 42^__ 206 __ 66 _ 84 _ 82 __ 232 _ 438 __ 54 _ 48 _ 60^__ 162 ___ 602 so_whats_happening __84 _ 92 _ 36^__ 212 __ 74 _ 86 _ 88 __248 _ 460 __ 48 _ 42 _ 46 __ 136 ___ 596 DonSutherland1 ______ 62 _ 94 _ 48^__ 204 __ 56 _ 88 _ 78 __ 222 _ 426 __ 34 _ 72 _ 54^__ 160 ___ 586 ___ Consensus ________72 _ 92 _ 30^__ 194 __ 58 _ 84 _ 82 __ 224 _ 418 __ 50 _ 42 _ 38 __ 130 ___ 548 RJay _________________ 46 _ 86 _ 60^__ 192 __ 66 _ 64 _ 88 __ 218 _ 410 __ 74 _ 42 _ 18 __ 134 ___ 544 wxallannj _____________ 48 _ 78 _ 60^__ 186 __ 74 _ 96 _ 62 __ 232 _ 418 __ 70 _ 36 _ 10 __ 116 ___ 534 wxdude64 ____________ 78 _ 86 _ 21 __ 185 __ 48 _ 82 _ 80 __ 210 _ 395 __ 50 _ 46 _ 30 __ 126 ___ 521 RodneyS ______________86 _ 82 _ 23 __ 191 __ 36 _ 94 _ 70 __ 200 _ 391 __ 40 _ 40 _ 48*__ 128 ___ 519 hudsonvalley21 _______72 _ 94 _ 30^__ 196 __ 44 _ 92 _ 72 __ 208 _ 404 __ 42 _ 32 _ 38 __ 112 ___ 516 Tom __________________ 64 _ 92 _ 27 __ 183 __ 58 _ 52 _ 98 __ 208 _ 391 __ 56 _ 34 _ 28 __ 118 ___ 509 Scotty Lightning _______86 _ 74 _ 05 __ 165 __ 36 _ 64 _ 82 __ 182 _ 347 __ 44 _ 42 _ 28 __ 114 ___ 461 ___ Normal ____________94 _ 54 _ 00 __ 148 __ 26 _ 94 _ 88 __ 208 _ 356 __ 34 _ 22 _ 18 __ 074 ___ 430 __________________________________________________ Extreme forecast report _____________________________________ DCA _ Finished at -0.3, a shared win for RodneyS and Scotty Lightning (each +1.0), also Normal.

(25th) _ Changed SEA from +2.0 to +2.5 due to extreme heat expected 26th-30th (currently +1.2 to 24th). Makes no difference to contest scoring results as highest forecast is +1.7. Also changing IAH to +1.0 from 0.0, has not been falling off as expected past five days. About +1.2 after 25th. Rather wet looking last few days of June should drop that slightly. (30th to July 1st) _ Posting final anomalies and adjusting the provisional scoring. Underlined are final, otherwise estimated from 29th CF6 and 30th climate reports. NOTE _ Snowfall contest final results will be available soon in the MAY thread.

I'll go for trace. Will set the order of entry as one ahead of A777 since I know that to be the case, the table already existed when A777 entered. Thanks, as I say, it won't be a factor anyway in all probability.

If you would like to enter the summer maximum contest, head on over today, it closes for entries tonight (at 06z Mon). We have 24 entries so far.

Tiebreaker fully explained in my recent post (before the table of forecasts above the post from A777) ... basically, highest error is eliminated in two stages, if that fails to separate, then it's order of entry into the contest. Since you probably edited (going by quotes) can you estimate when you edited? I really don't expect the tie-breaker situation to go as far as order of entry especially for a forecast like your own which is well separated from others and unlikely to generate similar errors at four locations (not saying you can't win though, just unlikely to be tied). (example) ... two tied with total departure of five, 2, 0, 2, 1 and 3, 1, 1, 0 ... the 2021 beats the 3110. ... two tied at 2,0,2,1 and 2,1,1,1 ... The 2111 beats the 2021 on second elimination. Concept is basically the same as sudden death elimination in a golf tournament. First hole is high score. Second hole is the remaining high score. Then darkness falls and we go into the clubhouse to settle it. In general, entries are still accepted to the end of the day, 06z tonight is the deadline. Edits are accepted too but will change order of entry stat.

Decided to work on the table of entries mainly because I can now easily spot late edits and change the order of entry. I am aware that WxWatcher007 edited his original post but probably not that long after posted? anyway, won't matter as it looks to be in a range where ties would be unlikely to go to order of entry anyway. Will be proofreading this to make sure I have the right numbers in the right places, some people entered in a different order so check your table entry, if you think it's wrong after the deadline, let me know (I won't be finished proofreading this until later this evening). Just to clarify, you may edit up to the deadline, and further entries are welcome, will be edited into this table. Use the table to get an idea of what values are taken. So far it turns out that two entries are identical (CAPE and WxUSAF). Table of entries for Mid-Atlantic summer max 2021 contest Order of entry is regardless of editing unless the forecaster chooses to inform the organizer of edit time, in which case the order will be amended to reflect the time of editing. Order of entry (the number in brackets) is a last resort parameter for separating ties, after two rounds of "largest error" determination. See June 12 post for details on tiebreaking this year. As a courtesy I will concede to anyone on order of entry if that becomes an issue -- in other words, I cannot win this contest on order of entry. The table of entries follows the order of warmest DCA to coolest DCA, with IAD a secondary and BWI a tertiary factor in setting the table order.

So you will see the highest order of entry number is 25. Changed the order for WxWatcher007 to 20th since he says he edited quite recently (but I saw his edit before A777 entered as the table was already under construction then). No worries as I bet the order of entry won't come into play, the errors will settle any ties if required. Hopefully somebody wins outright. Consensus values for the contest are now calculated (means rounded to nearest whole numbers). (late note: I added Weather53 to the table, even if his entry was a few hours late, I missed seeing it until today (June 26) for some reason and I don't think there was any really useful information available on June 14th that wasn't available to everyone else the day before ... so we have 26 entries now).

Bump for confirmed deadline -- no extensions now planned. In the original post I had listed the max to date, two locations have improved on those by one degree since I posted. Thanks for your entries. I will make up the table of forecasts tomorrow night (as 06z is only 11 pm where I live) and have it ready for posting at the deadline. If anyone has ideas about seasonal max at other U.S. locations, we have a forum-wide contest opened up in the "general weather" thread and the same deadline as this contest although a late penalty arrangement exists there (basically you lose the square of late days, e.g., 2.5 days late would cost 6.25 points). Please note in this contest, no late entries accepted, but feel free to edit to the deadline, I will check for edits but won't start creating the table of entries until around 04z Monday which is midnight Sunday in EDT (I think). _________________________________________________ Scoring: same as other years, the sum of your departures from final seasonal max numbers. However, I will announce in advance that in the case of a tie (for any position) the order will be determined as follows: (a) smallest maximum error (b) if necessary, second smallest error (defined as smallest of three errors left to separate after (a) eliminated) (c) if still tied, earliest entry (regardless of edit times if applicable since not visible to readers) ... ... ... most do not edit anyway so probably a "moot point." ______________________________________ An example of the tie-breaker, let's say two tie for five total departure points and get there with 2, 3, 0, 0 and 1, 3, 1, 0 ... the maximum error is the same (three) but once taken off the table, then the 1, 1, 0 will finish ahead of the 2, 0, 0. ______________________________________ There will be a secondary award for most direct hits and that will be separated the same way (since if necessary both or all will have similar numbers of zero errors, the separation will be achieved by looking at maximum errors). Last year if my memory is reliable the winners had total departures of 3, and there were a few entries with two direct hits.

The deadline for entries has now arrived. Late entries are accepted but with a late penalty of (days late)^2 (or days late squared), with the "days late" determined by hourly precision. Therefore if you read this within the first day of the late period, your penalty will be quite small (the contest is scored out of 100 as explained in a previous post). By day two you are looking at a rather significant late penalty increasing from 1 to 4 points and on day 3, from 4 to 9 points. This is a table of entries received. "Expert consensus" refers to a group of pre-season outlooks from noted hurricane research groups, all of which came up with forecasts close to this expert consensus. "NOAA median" refers to the average values of the ranges predicted by NOAA. The contest consensus is based on forecaster entries and does not include the expert consensus or NOAA median. The consensus is the mean of all forecasts submitted. The forecasts are listed from most to least named storms, and within ties, the numbers of hurricanes or majors will determine the order; if nothing separates the forecasts at all then order of entry is used.

Will check for any amended forecasts or new entries within the deadline and incorporate them as required. Our consensus is just slightly higher than the expert consensus and actually quite similar to many of the individual forecasts within that consensus which has members at 18 and 19 named storms. While almost everyone found a unique forecast, one forecast did overlap an earlier one, in that one case, the earlier forecast would be considered the winner if those numbers are the best forecast. Thirty forecasts received so far, plus the two additional entries. Good luck to all !

He does have a flame thrower.

Note to forecasters: There will be a separate thread this year for the "seasonal max" contest. Hoping we will get a few more entries that way.

In past years I have added a seasonal max challenge to the ongoing temperature forecast contest. This year just to shake things up a bit, I am going to open this separate contest in the hopes of attracting a larger field of entries. The contest asks you to predict the 2021 annual maximum temperature (F) at ten locations. The contest winner will be the person with the smallest total departure from these outcomes. Make your forecast in whole numbers please, any decimal entries will be converted to whole numbers. The ten locations are: DCA _ NYC _ BOS _ ORD _ BIS _ ATL _ IAH _ DEN _ PHX _ SEA (up to you to research what has already happened at these locations, BIS hit 106 yesterday). Deadline is end of Sunday 13th (Mon 14th 06z) with late penalties as follows: number of days (by hourly time stamp) squared. 2.5 days late gets a late penalty of 6.25 points ... etc.
