Short term, how far south does the line that potentially has some severe storms tomorrow make it tomorrow evening. Right now it looks to be after nightfall tomorrow that the front nears and it appears the line of storms weaken as well,  but still may contain some severe cells. Stay alert on that tomorrow, and will post to facebook. Then that front stalls and will be a focal point of another round of rain this weekend. Question is, how far does the front push and where the steady rain sets up Saturday night, and Sunday. There will also be showers Saturday,  mainly Wv mts.

18z GFS 2m temperatures next 384 hours. Now details will fail, overall outlook should hold. What to expect. As we close September and go into October, expect widespread frost ,freezes.. Especially valley freezes and those frost pockets, looking from this far out, a range with some mins falling into the 18-24° range looks reasonable. 28-33 most locations. Again, this will ne tweaked on numbers, and timing.

gfs_t2min_wv_45

This will kick start areas of slow changing leaves. It may also make for a shortened foliage season. Keep in mind, many areas that have those typical early changers, a lot of those spots, the trees have already lost some leaves prematurely due to anthracnose. You go out on western Cabin Mt across the top. Some maple areas are past peak now, and that did not contain much color, due to early leaf drop.  Heres a pick from Bittinger 2nw Valley today2018-09-20-15-51-41

Those leaves fell without much color at all. So, its some of the early changer are bare, others remaining green to just beginning to change. Wv high ground, Sept 29- Oct 6 should be good for best colors. Blackwater Canyon, Oct 4-12… Those cold temps should ignite the change. Many areas will fall in that date range as well. Later than last year with the warmth of this month vs the cold start to Sept last year.  Not much off normal, assuming these dates play out this year. Last year, the 2nd half of September warmed, and that slowed down the later changing trees to early Oct.

Last but not least. This will all involve timing of the fronts and precip available, first flakes early Oct are not ruled out yet. 3 members of the GFS ensemble package has it, 2 of the ECMWF. Here is the GFS gefs_snow_ens_washdc_65

18z GFS…. S, S, S, S YES, the S word is on the model. S should stand for, take with a huge grain of Salt.  BUT, its 15 days out, and while October does look to start out cold. I believe first widespread frost and freezes are late Sept or the first week of Oct. The 18z GFS does put out the seasons first flakes around Oct 3rd-4th. At this point, is it likely. NO. Is it impossible, no, its possible. Way too early to tell. How much cold air is able to push on the heels of a early season cold front, and how much moisture is available. Long shots for it to occur. . So the 18z GFS out day 10-16 is as much for fun as to take serious. Having said that, here it is

  Last years start to September vs this year…

A much warmer front half of September this year, vs last year. Last years foliage season got kicked off rapidly across the high ground with the maples. This year, outside of the early season trees affected with anthracnose, we are lagging last year, but I would not say far off par for normal. The very warm start (front 7 days) to this September has helped the overall average on the month be well above normal, while the daytime maxes the past 8 days have been much cooler, in large part under a east flow, foggy, wet conditions in which may help aid in some color change. One big thing lacking, due to the cloud cover, wet conditions, we have had a blanket to prevent nightime temps from falling off this month. Last year we had some nice big chilly highs push in, clearing us out, letting temps fall. Not the case this year…..and to be honest, I don’t forsee this chance not until the last week of the month or into week 1 October.

Really riding the Euro(Ecmwf) on this. The GFS just looks odd. With a brunt of the precip occuring with S/Se winds, it makes 0 sense to dry out the downsloping areas on the east side of the Alleghenies like the GFS does, the ECMWF does the opposite.

Leaves……

Nope still here. The leaf season. This is setting up to be a funky fall foliage season. Mentioned in many post in late August if you were following about a fungal disease caused by the wet weather causing some tree types(especially maples) to drop leaves premature. Some leaves shrivle, some spot up, and hang on. Well that seems to have affected a portion, how much, depends on the area. Lots of those fell ,leaving primarily green maples with some color. I was walking around observing this evening, lots are on the verge of change across my area in Garrett County. I think the shorter days, and the cool down in max temps the last week after the very warm September start, and the constant cloud cover  may be helping, but not as much if we would get some clear cold nights. They have been few in this overall wet damp pattern.. That said, this year vs last year on this date is very noticeable. Remarkably less color. Last year the maples went early, set off by a cold September opening and early frost. This year, that warm combo, with some early maple leaf loss, has left the early changers gone, and remaining mainly on the green side.

2018-09-14-17-45-38

On the verge, I tend to think these will start to change fast despite the lack of cold temps in near term.

next 46 days, weeklies do see our first flakes, in late week 2-week 3 Oct peiod. Take that with a grain of salt, and 3 tablespoons more.

Tomorrow night, I plan to show some comparisons of current foliage vs last year, with month to date temps. Much colder Sept last year, with leaves much further along. Also, this year is influenced by anthracnose in areas, which will hinder colors in areas.

FLORENCE

The track from last night holds fairly well tonight, with the exception of another slight south trend. The broad moist east flow will provide the opportunity for showers over the next few days, mainly Friday and Saturday. Our significant rain potential comes early to mid next week. Tweaks in timing and amounts remain. As of now it looks like a 1-3″ rain event with areas up to 4″. Now, the 12z Euro turned north a tad earlier, tad juicier and puts out 2-4″ amounts. Should that occur, flooding of more significance would occur. Right now going with 1-3″ which would cause some flooding with waterways already high.

FLORENCE UPDATE

This afternoon, models came much more into agreeance. Whether this holds, remains to be seen obviously. The ridge is strong, and it appears this will shift the storm more west into the Carolinas, inland and up west of the mts. Well, what does that mean. It means not much rain in our area until early next week. For the Carolinas, it means they take a big wallop of the catastrophic level late Thursday night, through Saturday. This latest track(my gut thinks this holds) spares the words like, catastrophic, serious, in our area. Now, we still look to get rains as the remnants lift north. This looks like the type that can cause already high waterways to come out of their banks in spots, but not in a major way and not in anyway more than we have seen already. Areas north that saw the flooding this past weekend, I don’t currently see a repeat of that.  Rainfall amounts are looking to be 1-3″, isolated higher, exception vs rule, if, and I stress IF things remain on this course. A slower movement, a quicker lift north could again alter that and increase these totals.

Here is a look at Florence today

Florence stats and NHC projection cone(notice the more southward turn in their cone)Screenshot_20180911-200511

The 12z ECMWF precip type next 240hrs and amounts. Notice these amounts are through mid next week, because the remants pass Mon-Wed timeframe(precip totals also include some precip prior to the remnants, same as the GFS)

Lets look at the 12z ECMWF ensemble members on Low locations, thats a lot of agreement.

The 18z GFS, notice the similarity now to the 12z ECMWF, and amounts off the model.

Spaghetti Charts, that south trend, and the west path, theme of today and given the ridge north, seems legit.

A closer look in as the 18z 3km nam comes into range of landfall. 10m winds(not gust, gust will be higher at landfall)
