I would think only a matter of time until it gets your yard and seedlings.
-
Rain has started here as the rain area has moved in from the SW during the past 30 minutes. More mold and fungus guaranteed.

August 2020 General Discussions & Observations Thread
frd replied to Rtd208's topic in New York City Metro
Do you think by day 10 we may start to see a couple days of NW flow, versus the continuous Easterly/NE and SE flow depicted by the models? -
Are you worried about too much rain coming? Will it disturb or displace the seedlings?
-
Exactly, Winds either from the South, SE or the East for days on end. Like to see the EPS later.
-
Would not be surprised to see that set up you mention in September ( even early October ) at some point. I believe in the past we have had cold frontal passages and then the building High to out North and East a few days after providing a pathway for a runner up the coast. Of course the fine line between a curve out to sea , or a real threat to the SE and Mid Atlantic areas.

You see that persistent Easterly flow and East fetch on some of the modeling. Some wave models bring 8 foot waves into the lower NJ. and Delaware surf zone by the weekend. Strange summer so far. I am just hoping for some NW winds behind a legit early Fall cold front, might need to wait on that. Was at the beach yesterday , and it was a marvelous day with the wife and the kids. Not crowded, surf at about 72 , seagulls didn't eat my pizza .

What ? No way !!!! I don't believe it, unless they hacked Isotherm's formula.

Do you lime ? Or, do you do a soil test ?

Another day another record , another 1,000 year event. https://www.delawareonline.com/story/news/2020/08/07/friday-storm-delaware-isaias-delmarva-power-flooding-rain/3324504001/ The Delaware Environmental Observing System measured 1.03 inches of rain in just five minutes at its Greenville station near Winterthur, state climatologist Dan Leathers said. According to the NOAA Atlas-14, the document that the National Weather Service uses to examine these types of events, that amount of rain in five minutes would be expected less than once every 1,000 years, Leathers said. Leathers said he and his team were still looking at the storm in more detail Friday night. The storm dumped more than four inches of rain at that Greenville station in around 30 minutes, Leathers said, and the area near Hockessin Fire Co. saw more than three inches of rain. So, too, did the Claymont area. As of 1130 p.m., more than 11,000 Delmarva Power customers were without power. It all happened quickly. The National Weather Service issued a severe thunderstorm warning at 5:38 p.m., when a storm with wind gusts of 60 mph and the potential for hail was over Kennett Square, Pa., just over the Pennsylvania state line.

Maue commented in this.

Totally agree. Between the near miss tornado and over 6.75 inches of rain this week, flooding is real . Oh and you might like this video from Bear, DE. regarding the F1 long track , and the recent tornado and severe storms.
-
Radar indicates that storm in extreme SE PA and Northern DE means business . Torrential rains here now. Streets already flooding .
-
Another tornado warning in Northern Delaware , Jeez ! Storms moving onto my location now.

Just pointing out two contributors that might be favorable. But honestly, the correlation is not strong and we are currently out of sync with things that use to work, or could be used in a analog set, or at the least, had exhibited some tendencies to be pro cold for our area versus warm. Challenges continue to mount for useful winter seasonal forecasts.

Speaking of Nina odds. A post by Don S yesterday below. If you are wondering today's SOI is + 22.40 Seems to me a good bet we get some sort of Nina developing by Fall. The one thing that interests me is the backdrop of the solar minimum. And, the eventual outcome of the QBO in Dec . and early winter. < Today, the SOI was +25.73, which was its highest figure since October 14, 2018. In all three August cases when the SOI rose to +25.00 or above and the August ENSO Region 1+2 anomaly was -0.75C or below, winter saw a La Niña. The most recent such case was August 2010. >

From the NYC thread. Check out the drop in SSTs since the tropical storm. Will need several weeks to get them back up . Of note as well

Even the end of next week looks to be rather wet according to Mount Holly's long range outlook. I tend to think if this pattern continues maybe over seeding can commence earlier this year, rather than after Labor Day, as @CAPE mentioned . I keep reading that as the Country dries up drier weather may settle into the East on a extended basis . However, this change seems to continue to push out further and further into the future. From Mount Holly AFD : Looks like the late-week period may be interesting, as the front may stall near or in the area, with deterministic models showing multiple rounds of convection occurring in proximity to it. Certainly a heavy-rain threat from a pattern recognition perspective.

Admiring radar over your area. Incredible !!! Missed the bulk here but precip totals South of me are 2 inches and over. Put those sprinklers into storage . The rare AM electrical storms are lots of fun !

I know I read a couple posts by HM on the QBO behavior during the past 6 months, and even recall some insights as well from Dr Amy Butler. Strange year so far for the QBO for sure. Good luck to those whom want to put out a winter forecast for 20/21. I would say the odds of discovering the correct winter drivers at about 33 %. Those who love the warm train might go climo ( 1990 - 2019 ) + 2 degrees. Those cold and snow weenies better hope for a 95-96 repeat. Sure we can get a cold snow event but difficult to see cold lock in with the same issues re-appearing such as the enhanced fast Pac jet and difficulties in achieving properly timed HL blocking ( or any blocking for that matter) along with the elusive -NAO. Speaking of stratospheric oddities.

@psuhoffman Good points on the post above. Analogs post 2010 have become useless to a degree. And, since 2015 you can probably even reinforce that notion with the Super Nino ( residual ocean warming , etc ) and add to that the recent ocean heat waves taking place. A somewhat newer phenomenon. I see even the great Don Sutherland has added something fitting and new to his weather summaries and look ahead monthly forecasts/stats. PSU , see here ( bolded ) from Don's recent post. Since 1990, there have been 11 La Niña events, 6 of which followed an El Niño winter. 10/11 (91%) case saw warmer than normal September. All 6 following an El Niño winter were warmer than normal. September mean temperatures for New York City for those cases were: 11 cases: 69.9°; Subset of 6 cases: 70.8°; Entire 1990-2019 period: 69.0°. The September mean temperature for all La Niña and neutral-cool cases following an El Niño winter (1950-2019: n=13) was 69.9°. Overall, the evolution of ENSO, along with the observed ongoing monthly warming (1.6°/decade in NYC and 1.5°/decade in the Northeast Region during September 1990-2019), favors a warmer than normal September. He is incorporating the new climate warming into his summary, very interesting. For me personally , I see no end to the issues in the Pac this winter that have haunted us the past 3 winters. So many elements in addition to the Pac are negatives for a cold and snowy winter in our part of the world.

After replacing the mulch I had to do it again this morning. That line had a few heavier cells go across the upper Chesapeake Bay/Eastern Shore which dropped .30 inches of rain here last night . Total with TS was 5.75. Ground soil should be good for a while. Refreshing this morning at 67 degrees when I woke up.

And don't forget, that was back in the day when a Nino did what a Nino was suppose to do. In this day and age with global warming the outcomes expected are no longer so simple. Since 2010 there have been noted changes in various mechanisms that would typically deliver cold and snow to the East with a moderate to almost strong El Nino. The use of analogs prior to 2010, to me, prove little value. A blended approach to forecasting the Winter IMHO might be the best way to go. Of course they also need to be tweaked and modified for GW.

HM spoke about this potential yesterday.

True. Hard to combat the high sun angle. With decreasing sun angle getting under way and longer nights coming up the reseeding shall begin. Black Beauty is pretty good. On a weather related note bluewave posted something very interesting a week back that the dews/humidity levels are rising since the last Super Nino. I imagine that may play into the higher overnight minimums in the summer, and the growing issue of mildew, plant fungus , etc. So far this has been the case from back in May :
