Well I truly dislike imposing any late penalties especially on hard working forum-asset posters, and I tried to contact RJay to avoid any significant bites but found message box full (I think) ... anyway, contact me if the penalty seems out of line (in the past few months I have basically been going with 1% per half day late which is more lenient than the older regime). In any case, here are tables of entries for both contests. I could also mention there's a tropical seasonal contest in the tropical forum, some of you are already entered in that, and deadline for it is June 5th 06z. Welcome Terpeast, I believe it's a first time entry in our contest. I wish StormchaserChuck would enter all months as his average score is pretty good. Rhino16 joined up in March and has been entering each month. I also continue to hope we will see a resurgence of the contest participation to levels of yesteryear. But it is what it is, and I am happy to continue, I suspect some of you intimidate the potential entrants with your prowess (and some of us do not) ...

A few days late but no doubt the hottest days of 2023 are some distance away ... so as always, predict the highest temperatures to be expected this summer at the four airports: DCA IAD BWI RIC and I will start the ball rolling with 102, 102, 103 and 103. Contest deadline 06z June 17 (which is Friday night). Tie-breaker details in a post in thread (lowest errors break ties, order of entry the last level separating ties)

I recall a lot of forest fires in ON and QC in spring 1977. But it is unusual to have this many at any time of year, summer tends to be fairly moist across the boreal forest regions north of the lower lakes. Persistent high pressure over central to northern QC or north of Ontario quite unlikely past mid-June as the storm track almost always energizes across inland northern Canada in summer. So I would not expect this regime to persist, it may morph into a persistent high closer to New England and New York state if it doesn't collapse entirely. It has been anomalously warm in north-central Canada since April so I am thinking there won't be very frequent below normal outbreaks into the Midwest at any point, and if the Midwest runs very warm, hard to avoid at least a moderate positive anomaly in the inland northeast U.S. A few months in the past have seen much higher anomalies as far east as Toronto compared to NYC. Both July 1916 and 1921 were much warmer relative to normal in Toronto than in NYC. There's one place a ridge can set up, around MI-IN-KY-TN that spills heat into the lower lakes and OV but if persistent low pressure can form near 37N 72W then NYC can be alternating between subdued heat and cool, cloudy and sometimes wet intervals. (this was not the case in 2009 when a larger northeast flow extended well inland).

1949 had a very dry spring and early summer, a hot June and more heat in July and August, cooled off somewhat in September, and returned to significant warmth in October. Late November was briefly cold but the winter of 1949-50 was among the mildest on record.

Wow, this contest may require an assistant director at this rate. There will also be about a dozen along from two other forums in UK and Ireland. I will rank them in but issue two ranking lists at end of play so you can see how you did against American Weather folk and the somewhat larger global field. Expert forecasts will be scored but ranked outside your ranks. As I've been saying, you can edit away to end of Sunday June 4 without posting about it, as I have not collected the forecasts yet. FAQ 1. January storm ... does it count? Yes, the contest asks you to predict the count at end of year. 2. December storms ... do they count? Yes, same as above. 3. Tropical depressions not reaching TS status, not named, not in the count -- these do not count unless re-analyzed before Dec 31st. 4. Storms that have two active life cycles. They count as one as per NOAA protocols. 5. Prizes? Yes, promotion to PGA tour. You must also excel at golf and qualify some other way. So it's not a real prize. 6. Prestige? I think so, if you can beat 50 people and the recognized experts, that says something. 7. Same forecast as somebody else ... up to you to check for this, earliest post ranks higher. 8. Medicanes, South Atlantic canes ... no, and no. SCORING SYSTEM will be same as past two years, explained with table of forecasts in a few days. Basically, you lose fewer points for errors in storm count than in hurricane and major counts (this after that season with the 30 count that gave almost everyone a negative score). Decimal forecasts are allowed and are scored from their precise values.

Years with significant heat in early June sometimes see a return to that heat on several more occasions (e.g., 1919, 1934) but another outcome is a rather cool mid-summer and more heat in September (1895, 1925). I suspect this will turn into a relatively hot summer with a few cool and wet intervals, in this climate, harder to avoid east coast ridge building over the anomalously warm NAtl. It is also quite warm out here and pushing up a bit higher each day to mid-week. My idea for the summer pattern in general is that it may be prone to severe heat waves in central states and the western interior, and that the east will alternate between near average and hot spells with a bit of a westerly rather than south-westerly flow bias which can mean a rather dry regime, but no doubt with a few interruptions.

2023 Atlantic Hurricane season
Roger Smith replied to Stormchaserchuck1's topic in Tropical Headquarters
Please note, forum season prediction contest closes end of day June 4th (06z June 5, 2023). NOAA forecast is 12-17, 5-9, 1-4 or median 14.5, 7.0, 2.5. UK Met Office not buying into El Nino suppression and predict 20, 11, 5. UA also higher than expert consensus at 19, 9, 5. (I am saying 19, 12, 4 but not an expert) CSU more conservative at 13, 6, 2. TWC saying 15, 7, 3. The contest is here in this sub-forum. I have invited weather nerds from UK and Irish weather forums to enter also. -
Contest deadline extended to June 4th end of day (06z June 5, 2023). Contest open to members of UK forum Net-weather and Irish weather forum on boards.ie, on separate entry portals (I will list any forecasts submitted here). Same deadlines. National hurricane center says 12-17, 5-9 and 1-4, or 14.5/7.0/2.5 so that will enter contest as "NOAA median" although UK Met Office says 20/11/5. CSU is predicting 13/6/2 and TWC 15/7/3. I will score all of them but ranks will not affect your contest ranks. Edit any forecast already placed in the thread without notice needed, as I will construct a table of entries from what I see on 5th of June.

28.42" of rain fell at one location in Guam. GFS continues to stall Mawar east of Taiwan, but latest track across N Pac is closer to Gulf of Alaska.
-
If the GFS is correct, Mawar tracks west towards Luzon and stalls east of Taiwan around 29th, then is caught up in the subtropical jet and moves all the way across the Pacific around 35-40N to slam into the west coast of the U.S. by about June 8-10. That would dump a lot of subtropical heat into the circulation and might be a signal of a very hot spell in the central and eastern U.S. by mid June.
