I've been tapping into KDOX, but it obviously doesn't have great coverage our way.  Can anyone suggest a good alternative while LWX is down?

Is a good source for radars and I've been using it since lwx is down.

Also, weather underground was mentioned.

I am sure we go dry for the winter. But, rather active again, Friday now looking not so hot,  and another system early next week.  

 

From Mt Holly AFD

Thursday night/Friday: Guidance has come into better agreement
that a weak coastal low will form Thursday night and pass
sufficiently close to our area to warrant appreciable
precipitation chances. Consequently raised PoPs a fair amount
this package (they may need to be raised further in subsequent
packages), but given that the low will be weak and fast-moving
expect rainfall totals will be limited to a few tenths at most.
By Friday afternoon cooler and drier air will filter in behind
the low and expect rainfall to generally come to a quick end.
Highs will likely only top out in the low to mid 60s in most
locations.

Saturday/Sunday: Dry and seasonably cool conditions will
prevail through the weekend with daytime highs generally in the
mid 60s and overnight lows in the low-mid 40s. Some frost will
be possible in the colder spots of eastern PA Saturday but more-
so Sunday morning as the radiational cooling setup looks fairly
good (at least 5 days out)

Monday: Another shortwave and associated area of low pressure
may impact the area on Monday but details are fuzzy at this
point, with the EC/CMC depicting a stronger system (and closer
to the coast) relative to the GFS. Medium-range Chc. PoPs seem
appropriate at the moment.

@frd  I have been burned the past few years by assuming our great late fall patterns should resurface during the winter.  A lot of other folks on here warned against it and I guess you just have to take your lumps as a weather nut and...live and learn.

With that said...it looks like the eps has been steadily hinting at some mid Oct heat coming, along with a continuation of our recent dry conditions..  Id be ok with a week of 70's before the steady slide into winter.

I share your thoughts. The last 3 winters did not show the real pattern until after December 20th. Actually last 3 years there has been a huge rise in temps after December 20th. Along with that the last 2 winters had record or near record high NH / NA snow cover early on, only to have that North America snow cover rapidly decline by mid Jan. of both winters to very minimal levels. ( Sorry Judah ...ah the poor SAI and total snow cover = no value )  

So, as you mentioned,  in this new day and age do not be fooled by anything that appears to look favorable until you measure a foot of snow outside your door.   

Hey, I am still open to all options, but I will keep the bar low and exceptions in check.

Pouring here. Not welcomed at all. Figures, after I seeded. This is a separate area of rainfall from that main area to our West.  

Current downpour over 10 minutes and would do the summer thunderstorms justice.

Rain gauge at 1.10 ans radar estimate here

If you have straw or you seeded existing grass I don’t think the rain will hurt your seed. Probably help to have some heavy rain drive that seed to the soil

Good comment,  thank you. I over seeded an existing lawn. Height of grass should prevent wash away. I just worry, that's all.  I also core plugged it too with a machine. From a weather perspective looking forward to the cool down with nice morning dew,  and then a gradually warm up as we near mid month.

Same old story, as mentioned a bit ago that area of heavy rain meant business and has caused a FA

If you’ve aerated, then the rain will wash some seeds into the holes that you made and be the perfect medium to germinate; cool, dark, and moist. In a couple of weeks, the lawn will remind you of a man that got a hair transplant with new grass shoots sprouting from the holes.

The next time you core your lawn do it with the grass really high. Wait a day or two and then cut the lawn short. Doing this will obliterate the plugs giving you a bunch of loose soil sitting there that will aid in the germination of your seed.

I agree with this one part in particular. The dark part. You can plant seed in bare soil, cover part of it with straw and leave the other part uncovered and the covered seed will immediately germinate while the uncovered either won’t germinate at all or will be very slow to do so. That darkness matters for seed that is not fully covered by soil.

Try spreading peat moss over the seeded bare area.  Peat moss keeps the soil more moist and has additional nutrients compared to straw.  Takes a lot more to blow it away too compared to straw.  I've had good luck with it in the past.

This is what I use. Its a bit pricey when you have a larger area to do(like I just did) but it is very effective and I despise straw, so worth it.
