Recall well that event, though it was mainly on the 25th in NNJ - not all that much RA but strong winds taking down newly leafed-out trees and low 40s. High at NYC was 46, about 30° below the norm for the date. And the snowy cold winter of 1960-61 also had a near-solstice surprise - on 5/27 we had cold RA at low 40s and a few pingers.

Had a sprinkle an hour back here in Augusta, but radar says some more significant stuff is now arriving. Temp near 50 and probably about to slide down a few.

When visiting the Minnesota Arboretum some years back, I saw a Mongolian birch (Latin name forgotten) about 20 feet tall and 6" diameter. It had beautiful copper-gold bark, as pretty as any tree I've seen. Is your birch like that?

Shades of 2010, when the 13 weeks ending May 7 featured just 13 with BN temps and that quarter year ran nearly +8°, causing my apple trees to be in full bloom that early. Then May 11-13 had minima of 22,26,25, not only killing every blossom but also toasting all the ash and oak leaves plus some (usually hardy) sugar maple. Most damaging late freeze I've seen.

Could be even worse - the logging contractor who lived just across the frontier from St.-Pamphile, PQ had his garden killed on July 4th week 4 years running, before he gave up. (Back in the cold 1970s, when my pumpkins got scorched on 7/31/78.)

The description fits the Eastern tent caterpillar but the picture looks more like the forest tent caterpillar. The latter doesn't make visible tents, and in an outbreak can defoliate whole forest. They prefer aspen but will eat all broadleafed trees. The early 1980s outbreak in N. Maine/NB had these critters being called "army worms." People would open a door and a hundred would crawl in, causing some folks to move away temporarily. Squished caterpillars stopped a few trains from climbing grades. I have a coupe of hickories that I planted out back, but those take awhile to grow and don't do well with transplanting since they have a monster tap root. I laso planted a yellow birch and a tulip poplar, but the tulip is another fast growing tree that drops a lot of branches over its lifetime. Tulip trees drop branches, but they're not in the same league as weeping willow for that. Wood of tulip tree is about as weak as silver maple but the former's vertical growth habitat makes it less likely to break from ice or wet snow. There's a large one - 30"+ diameter and 70'+ tall, in downtown Farmington (Maine) that doesn't seem to shed many branches and has withstood a lot of snow and ice. Two houses up from that specimen is a littleleaf linden (European relative of native basswood) of similar size that is a bit worse for branch loss.

'Fraid so. Had never heard of autumn blaze so I looked it up. Seems highly regarded for fast growth, moderate size, fall color, and tolerance to urban conditions. It's a hybrid of red and silver maples, and the piece I read (which could've worked as ad copy for selling this variety, so maybe check several sources) said that it kept the strength of red maple, which is far better at resisting snow/ice breakage than silver.

If there's no green in the buds, I'm pessimistic, but I'd wait until July before giving up. And that pic confirms that it's not a Norway maple; if it were, I'd not be all that worried about losing an invasive, but it looks like a native maple. Oaks are fine here. Big ol’ leaves. Looking good here, too, though the leaves are only about 2" long - everything is late and this morning's 31-32 didn't help.

Does not sound good. A young open-grown tree that produces those side shoots is probably a tree in trouble, trying to save itself. I f any of those buds are within reach, try splitting a couple with your nails (or with a knife, carefully.) If they're green inside, there's hope. I'm assuming it was planted 8-9 years ago, not grown from seed in your yard. Is it the native red maple, or the variety of Norway maple that has red foliage? (May not make much difference, though.) Has anything changed near that tree? Soil compaction, root damage, change in water table, reaction to lawn chemicals? Kev/Scott: That oak also looks to be in trouble, unless it's merely showing the initial work of this spring's feeding by gypsy moth larvae. Otherwise, something looks to be killing some high-in-crown branches, and that often portends continued dieback. Hope that's not the case. Trees are usually tough, but odd things can happen. There was a very healthy looking pin oak growing in front of the Coke bottling plant in Farmington (Maine), a tree about 15" diameter and 40' tall that had lovely red foliage each fall. (IMO, pin oak has the best fall color of any oak.) Then spring 2 years ago it completely failed to leaf out, and in late summer was removed. I've no idea what caused its death.

Not promising much precision in diagnosing specific agents affecting tree health from a photo, but I'm always ready to make a guess whether I know anything or not. When I was at U. Maine, one of the professors noted that science had not really arrived at a firm reason why trees die. Not referring to death from disease, insects, wind, fire, but just running out of life. Maybe it's similar to why there's a cap on human lifespan, cell replication gets sloppy and bad things result (simplification, but not irrelevant.)

When we lived in NNJ, it was easily noted that those caterpillars ate the white oak group first, then the reds, then everything else but ash. Have not noticed that white-over-red preference in Maine, though the fact that Maine has hundreds of red oaks for every white probably mutes the gypsies' priorities. Lots of reasons for oaks (or any species) to show that symptom, and weakness due to repeated defoliation/refoliation certainly could be a factor. If the non-leafed-out branches are in the main crown and receive good sunlight, the cause is likely some outside agent like gypsy moth or some disease. If the bare branches are within the crown/shade, it could be natural pruning, though white oak doesn't prune itself nearly as efficiently as red.

Not for much of NNE. And sun hasn't been all that abundant.

Never got here yesterday - high was 53. Total precip thru 7 this morning was 0.57", most of which came 3-5 AM. Had a 10-minute downpour in Augusta at 8, now just very light stuff. Big Q: will we warm-sector this afternoon? Forecast says yes, though as Chris notes in the convection thread, svr chances seem to be retreating. SNH already upper 60s with mid-60s dews while AUG area was near 50.

More clouds than sun here but flirting with 60 so still a decent day. Blackflies made their appearance, and one took a bite. Can't remember ever getting bit on the 1st day before - usually they flit around checking the menu for 2-3 days before chowing down.

Usually EAB has infested a tree for a couple years before symptoms become visible, after which comes the quick death you saw. Apparently there is a very small minority of ash that exhibit resistance/tolerance for EAB, so I don't think the species group will go extinct, but will probably be gone as a significant component of the forest. Hillerich & Bradsby can switch to maple. Indigenous people in Maine and the Maritimes, for whom brown ash and the products made from it are important cultural facets, have no plan B.

That (the bolded) is my method to get an accurate measurement. However, I don't try to fill in the melt/sublime pit around the stake. I plant it in the fall on the most level part of the garden, which varies from year to year by what crops were grown, and it's 25' or so from the cleared path to the shed. Getting into shovel reach means snowshoes, and I make pretty deep hol;es in a non-glacial pack - would rather not make a bunch of large foot-deep impressions just a couple yards from the stake if I don't have to. My stake is white with black markings, but made from a 2-by-4 so not exactly thin. I guess we’ll just have to make do if this is the sort of stuff we have to deal with in the current climate regime that everyone talks about here in the forum. I've just distilled some snow/temp data for an informational paper I'm doing on climate change effects on forest management. I have model info for the Northeast but wanted to be Maine-centric, and chose CAR for the north, Rangeley for the western mountains, and Farmington for a lower elevation site still close to the landbase we manage. I may toss the cold/snowy 60s and 70s because they stand out even in a 125-year record like that at Farmington - snowfall 15% higher than in any other full decade and coldest DJF and DJFM temps of any decade. Here's what I've found: Farmington (1893-on) Snowfall: very close to 90"/yr except for 106" in 60s/70s. Max depth locked in at near 30" except 35-36 for 60s-70s. Snowpack retention (records start 1940): Cover 1"+ for recent decades down 3% from 40s-50s. Temps (DJF and DJFM, the period for frozen-ground logging): Significant rise this century, about 2F above 80s-90s and early 20th century. Caribou (1940-on) Snowfall: About a 5% increase this century compared to 40s-50s. However, max depth is down about 5" for the most recent 20 years. (However, I wonder if there's a difference in how snow gets blown around compared to earlier years. The 14" blizzard of late Jan 1977 added 14" to their depth, while storms of 13" and 14" in march 2008 each added just 4".) Snowpack retention: Cover 1"+ down 5-6% for the 21st century. Temps: Significant rise this century, about 2F above 80s-90s and early 20th century. Rangeley (1961-on, so no earlier check. Also, have not parsed their temp data.) Snowfall: Last 10 winters (119.7") same as 1961-on (119.8") Greatest depth 2000-on is 2" above 1961-on. Snowpack retention: 21st century 1"+ cover 2% higher than 1961-on. Conclusion: Little to no effect on snowfall and top depth, slight eroding of 1"+ duration, 21st century winter temp 2F above previous, probably due to more frequent/milder thaws.

Got low 40s RA from that one - typical. Same today, only it's upper 30s. Saw some catpaws and "almost-flakes" coming over Mile Hill on the way in, only Maine report of accumulation was 0.1" in Temple, and I found out that cocorahs site is above 1200'. Numerous 3-5" reports from VT cocorahs.

Just under 400' here, maples are about 1/3 full size, probably 1/2 by Tuesday, oaks barely breaking bud, ash still asleep. Only aspen/willows would be past the halfway point by the time that Euro goes crazy, and we're not getting 6-8 here (unless it's 6-8 catpaws.)

I've read that oaks can harbor the chestnut blight fungus without taking damage; hence the inoculum remains in the forest waiting for its real food. Tough roots for sure! On the state lot (gifted by Gov. Baxter's nephew in 1969) near Merrymeeting Bay in Topsham, there are several American chestnuts. A white pine plantation was established in 1959 on 15 acres that earlier had been a market garden for about 20 years. We thinned the plantation early in 1989, and that fall I saw a 5' tall American chestnut growing in a skid trail. After 50 years (at least) under a plow layer, the roots still had sufficient vigor to sprout 5 feet in one growing season. 22 years later the tree was 11" diameter and over 50 feet tall, but now it's been blighted - dead above 15' and soon down to the root collar as well. Welcome to the regulated world of gas cans. they are designed to prevent you from catching on fire from spilled gas. and they suck And the irony is that I've spilled far more gas using the crummy thing that I ever did with the old "unsafe" ones. They're evidently designed so that one needs to employ both hands to use them (unless one unscrews the entire spout, which I'm tempted to do.)

Dumped 0.18" from the gauge at 7 AM, but the heaviest was still to the west. At this point we'd need a 3-4" RA to threaten even moderate flooding, and that's not in the picture.

That's only valid for elevations above 5,000'. Gorgeous full sun day, and mild enough that the breeze isn't a problem.

Aspens showing some green at home, sugar maples in Augusta in full flower - looks like a good seed year for them (assuming tomorrow morning's freeze doesn't hit too hard.)

Thanks again for the work you put into this. Looks like the new version will add useful info in an easily accessed format. Good stuff!!

Agreed. The gray fur sprouts greenies.

Maybe -depends on lawn size. 32 yards will put 2" on 5,000 sq.ft.
