Without taste buds is the time to fry them up and give ‘me a try!

How are you feeling?

:lmao:

Taste and smell are SLOWLY returning.  They were both at 0.0 for like a week and now I can taste and smell some things again. Overall I’m fine though, running 5+ miles a day and doing everything I usually do.

It's basically the "useful" portion of the weeklies built into the ensemble run lol,

I’ve never seen anything “useful” about a three week forecast. A pattern recognition argument can be made for a forecast beyond ten days but even that is sketchy. I just can’t wrap my head around who the weather forecast a month in advance benefits. Christopher Newport on the Susan Constant?

Spend the money and come up with a model that is superb at 7 days. Now that would be useful.

Nothing at all after two days of flood watches.  Good thing I got 1.85" from Isaias because I think yesterday was the last chance for rain for a long time.

The flood watch was put in effect because of the already saturated ground in many places. There was never going to be a widespread event over the last 2 days, and some areas did indeed receive excessive rain in a very short period.

It does look mostly dry for the next few days at least. Mid to late next week could feature some storm chances.

My point and click has rain chances most of next week. I haven't been out to check how much fell last evening but I'd estimate 3". Close to 10" in 4 days.

It was tongue in cheek, thus the use of quotations. Generally not worth much, other than maybe providing an idea of the 'big picture' pattern going forward.

That said, extending the range of the ensemble system, and making changes(spending money) to improve performance inside of 10 days are not mutually exclusive. This GEFS (v12) upgrade provides higher resolution, and increases the number of ensemble members to 31. There are other technical changes in the model physics.

 

eta- the rationale for extending the forecast range and some of the 'in the weeds' changes to the model.

Quote

Recently, there has been a large demand for subseasonal prediction, and GEFS v12 forecasts will be extended to 35 days to cover this time range. To better represent large uncertainties associated with this time scale, SPPT (stochastic physics perturbed tendency) and SKEB (stochastic kinetic energy backscatter) stochastic schemes are taking the place of the original STTP (stochastic total tendency perturbation), and a prescribed SST generated from combination of NSST and bias corrected CFS forecasts is also applied to simulate the sub-seasonal variation of SST forcing.

You inspired me to dump the gauge. 2.90" for last night. I wouldn't be surprised if you have a bit more. My electric gauge had 3.76, but in summer there's lots of tree interference on that Davis, and it can't be trusted.

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.

Motorists run afoul of the weather in Greenville on Friday.
 

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.

80/71 here

Not bad out as long as you aren't moving too much. 

Unfortunately I’m moving too much lol. Lacrosse tournament at the park I work at today, unfortunately field conditions were muddy so had to do some rakin’. It definitely is muggy out. Good thing it isn’t 95 too though.

Yeah. I got 7.20" from the tropical storm and 2.85" last night. I said near 10" because I figured the trees might of interfered a little.

Yeah I have been outside working too. Lost most of the clouds and the sun is beating down now. Time for a break. (maybe a beer)
