Friday evening update, Sept 5th
The front coming through tomorrow (Saturday) afternoon is looking like it could throw off some possibly serious thunderstorms, and NOAA's Storm Prediction Center has our area at a slight (+/- 5%) risk of a tornado. While this means a tornado is not likely, it does mean that these storms could have strong gusty winds, heavy rain, and possibly hail. Timing right now looks to be in the mid to late afternoon, with a window from 3 - 9 pm. Once they arrive, they should lost about 1 - 2 hours.
As always, please do not rely on me for timely warnings but rather have your phone on and set to give you alerts from FEMA or another trusted source (I know, I know, but there it is).

Friday and Saturday looking nice, sunny and dry, highs in the 70⁰s and cool overnight near 50⁰
A note on tropical storm Imelda. This storm is trending out to sea now and should not be a significant threat to land in the continental USA. Earlier model runs showed a major hit to the southeast, and the storm will be watched closely, but the trend is favorable. Mark Furman asked last week about the Fujiwara effect, which is something that can happen if two tropical storms are close together physically. In this case, the effect is forecast to pull Imelda away from the coast as it gains proximity to Humberto.

Friday mostly sunny and a bit warmer, high in the lower 70⁰s

And here's a pretty picture of Imelda and Humberto doing their dance out in the Atlantic. That's Humberto on the right. If you head for the beach this weekend, be very aware of rip currents and rough surf from this combined system (if you click it it moves)

Wed Oct 8th
Fall arrives
Today, rain showers ending mid morning, the breezy. High upper 60⁰s, low overnight mid 40⁰s
Thursday and sunny and cool, highs low 60⁰s lows mid 40⁰s
Saturday gathering clouds and a bit warmer high upper 60⁰s low lower 50⁰s
Sunday and Monday we might see out first nor'easter of the season with rain and wind but for now going to say chance of rain Sunday into Monday as the storm also could be out to sea. Either way we'll keep an eye on it
Friday October 10th Weekend Update
First, sorry about leaving Friday off my last post. Guess I was in a hurry to get to the weekend!
So, Friday sunny, high in the low 60s, overnight low lower 50s.
Saturday sees gathering clouds with a slight chance of showers overnight becoming showers likely after midnight. We will start getting a bit of a breeze overnight but nothing to worry about. High upper 60s to 70 depending on how fast the clouds move in, low mid 50s.
Sunday gets interesting. We are expecting a nor'easter to pass by off the coast. How far off the coast and exactly when is still a matter of some debate. The GFS model is bringing the rain in the afternoon, but the Euro doesn't really get going until after dark. Either way, we are looking at a solid 24 - 36 hour rain event, which is good -- 1" to 2" spread out like that will give us a good soaking at a rate the ground can absorb, so little to no flooding and much benefit.
Also Sunday we will be getting wind. The steady 15 - 20 mph is no howler, and the gusts are forecast to only get up to 30 mph, so damage should be minimal. High and low temps should hover between 55 and 60.Note that the rain and the wind are likely to be significantly worse down the shore and on Long Island, so we will be hearing wind and rain watches and possibly warnings for nearby areas.
This type of storm also can produce coastal flooding as the wind and tide combine to drive the surf. Again, not a threat to MAPSO.
The wind and rain will probably continue most of the day Monday. Temps likely to continue to hover between 55 - 60. May get a bit of thunder Monday, but not likely to be anything serious.
The WPC graphic below is mostly focused on the coast, so don't let it scare you, the effects of the storm should be milder here.
Sun Oct 12th
Forecast is on track for a nor'easter bringing rain and wind
Chance showers this morning, then steady rain likely this afternoon, continuing through tonight and all day Monday, tapering off after midnight Monday night. Total rainfall for the period 1 - 2 inches.
Steady winds around 20 - 25mph with gusts in the 30s, definitely enough to really shake the sukkah.
I do not expect anything more than minor nuisance flooding, the warnings that you might see are for coastal flooding as wind drives tides onshore along the coast.
The good news is (1) we need the rain and this is the best sort of rain, slow and steady and soaking, and (2) by Wednesday we should be back to fine sunny autumn days for awhile
Thank you, Max! Between those two posts there was a ton of scary meteorological accounts on FB and elsewhere posting about this storm, with some headlines comparing it to Sandy and I was really hoping we would get a calming hyperlocal post from you laying it out how it is, so I really appreciate you giving me one less thing to freak out about this weekend.
We did stash our patio umbrellas in in the garage and cleaned up a few things that could have gotten blown around in the gusts. Nice to know this is most likely a manageable storm for us.
Monday October 13th
Forecast on track for light to moderate rain all day and less windy conditions
Today the rain continues, light to moderate, gradually tapering off later this afternoon and tonight to a slight chance by Tuesday morning. Wind still present although the worst is probably over, we may still see some gusts close to 30mph this morning. Some wind continues throughout the day, and into the night. High and low, mid 50⁰s
Tuesday some clearing, may see a bit of sun in the afternoon, high lower 60⁰s
Wednesday mostly sunny, high mid 60⁰s low 40⁰s overnight
Thursday and Friday should continue sunny with highs in the lower 60⁰s and lows in the 40⁰s
Weekend looking mostly sunny with highs in the upper 60⁰s
Wed Oct 15th
Fair Fall weather ahead

Sunday some clouds, especially in the afternoon, high near 70⁰ then rain possible overnight, breezy
Sun Oct 19 update
There is likely to be some thunder and lightning as the squall line moves through tonight, with brief periods of heavy rain and gusting winds. The rain, likely after midnight, may persist into the early part of the Monday morning commute.
Monday breezy with chance of light rain diminishing as the day progresses
Tuesday clear and sunny and cool
High today in the mid 70⁰s with gathering clouds, rain overnight likely
Highs Monday and Tuesday in the mid 60⁰s
Monday October 20th
At 7:00 this morning, there are still a few showers in the area. They should move through in the next hour or so, then breezy but mostly dry today, even some sun this afternoon. High near 60⁰, low tonight mid 40⁰s
Tuesday should be sunny during the day, high mid 60⁰s. Overnight could see some showers but nothing serious although it gets breezy again, low near 50⁰
Showers might carry into Wednesday morning, breezy
Thursday and Friday, clearing, continued breezy, high near 60⁰
Friday Oct 24th
Cool and clear for the weekend
Today, sunny high near 60⁰
Saturday same, Sunday a bit cooler and some clouds mixed in
Monday and Tuesday mixed su.n and clouds, high mid 50⁰s
Lows around 40⁰ but there is a slight chance of patchy frost, especially Sunday night, so get those most fragile plants under cover
Monday, October 27 (ok, a little early)
The main feature of the week's forecast is the complex low pressure system coming through midweek, likely bringing showers and gusty winds. The system has three parts coming from three different directions; it's a bit tricky trying to get timing and rainfall right at over 100 hours out. So lots of qualifications, hesitations, and a bit of guessing.
Here's my best try:
Sunday night: Clear and chilly, low around 40
Monday and Tuesday, mostly clear and sunny. High mid 50s, low around 40 overnight, Tuesday night slight chance of rain and breezy
Wednesday, mixed sun and clouds, breezy, high upper 50s low mid 40s, overnight chance of a shower
Thursday, rain likely. If the system shapes up like I think it will, we will have a period, probably Thursday night, of showers and some heavy showers possible. Blustery winds likely with some gusts possibly approaching 30mph. High near 60, low in the upper 40s
Friday chance of showers, high near 60, low mid 40s. Showers are likely to taper off in the afternoon and evening. Fingers crossed we should be dry for trick or treating
~~~~~~~~~~~~
The maps below are the current runs of the GFS and Euro models. Although they have some timing differences, they both show the storm's comma shape and the line of heavier showers moving through the area Thursday afternoon and evening. If you look in the lower right corner you can see hurricane Melissa, which poses no threat to us at all, but is showing up as a tight and powerful storm which will head out to sea and not towards us
