Yanksfan Posted September 12, 2014 Share Posted September 12, 2014 Is it just me, or has there been an unusual frequency of volcanic eruptions during the past six months or so. If that's the case, you would think that will effect our climate this winter, i.e. colder temps. Link to comment Share on other sites More sharing options...

Weathergun Posted September 12, 2014 Share Posted September 12, 2014 Tomorrow is a scattered line of storms again, IMO. Nothing widespread. We've been in this very dry pattern for months. There's no instability tomorrow. It's just rain. Link to comment Share on other sites More sharing options...
doncat Posted September 12, 2014 Share Posted September 12, 2014 Tomorrow is a scattered line of storms again, IMO. Nothing widespread. We've been in this very dry pattern for months. The dry pattern started around mid July.... was about 7" above normal precip at that point here so it was a wet first 7 or so months... even with the recent dryness, still about 3" above normal to date (at this station).

CIK62 Posted September 12, 2014 Share Posted September 12, 2014 I was actually wondering the same thing, would any of the experts like to chime in? Also there should be more particulate material in the atmosphere for the water vapor to coalesce on. This is how that April 6, 1982---10" snowstorm happened here, along with record low temps. I think it was the El Chichon Volcanoe that time. Link to comment Share on other sites More sharing options...

This might be a result of higher pressures off shore, and persistent on shore flow, which I believe limits upwelling. Any other ideas? Link to comment Share on other sites More sharing options...

The very strong block to our Northeast in August created a warmer pattern there which warmed the SST's. The persistent high pressure to our Northeast has kept the easterly flow going.

I could see warm offshore temperatures on one hand leading to increased blocking, suppressing the storm track south, but I could also see it also moving the baroclinic zone westward, resulting in a coast-hugger type storm track.

I'd take my chances with that versus some of the dry/cold weather we had 2nd half of Feb and all of March Link to comment Share on other sites More sharing options...

JLPhill Posted September 13, 2014 Share Posted September 13, 2014 Tomorrow morning looks to be the first morning low below 60 degrees across much of the five boroughs since June. Central park recorded a 59 degree low on June 15th. It appears that lows will remain below 60 over the next week. Next Friday morning looks especially chilly on the Euro (early first 40s in NYC?). My feeling is that the temps shown on the hi-res nam below are a bit too low. My guesses for tonight are: KNYC: 55 KLGA: 58 KEWR: 55 KJFK: 57 Link to comment Share on other sites More sharing options...

Figured we'd finish with under a quarter inch. Can't complain about dryness here, had over 15.5" for the meteorological summer and 1.07" so far this month via T-storms.

Isotherm Posted September 13, 2014 Share Posted September 13, 2014 After the coming 5-7 days of cooler than normal temperatures, we should resume a warmer than normal pattern for the Mid-west/East for the September 21st-30th period as the large scale trough amplifies into the Gulf of Alaska, flipping the EPO moderately positive at least temporarily. This current cool period is timed well, immediately following the EPO decline. Mid level ridge should expand in the E CONUS yielding possibly some low-mid 80s again for the final 1/3 of the month, and therefore sealing the deal on a torch September. In other news, the CFS V2 continues to furnace the CONUS for October. This seems to be in consensus with the Japanese based models as well as the ECMWF weeklies out through the first half of October.
