OBS Thread for PHL area : Sandy / Post Trop Phase

Of interest is what I woke up to this morning....nothing. That will change, but I figured that there would be more effects that what there was. In no way did I think we'd have tropical storm conditions this early, but I guess I was under the assumption that winds in the area would have already been in the 10-20mph, but they were and are rather calm. It has just now started to rain lightly, but since the showers we had yesterday evening (0.09"), no rain had fallen.

I want to add that this is not a "bust" post, or that I think it will bust, just my early morning observation from the coal region.

Currently in my backyard:

Temp: 51

DP: 51

Wind: wnw @3 mph with a gust of 7 mph

Pressure: 1001 mb or 29.55"

Rainfall: 0.00"

i think that was a extrop pressure. Cause hurricane schwartz just showed the pass and had 942mb pressure.

ray, or anyone else who can help with this. They say the winds are 90% of the flight level winds which are 108mph, does this support 90mph sustained?

Storm SANDY: Observed By Air Force #302

Storm #18 in Atlantic Ocean

Maximum Flight Level Winds Were 94KT (108.1mph 174.1km/h) In SE Quadrant At 10:14:00Z

Estimated Max Surface Winds 84.6KT (97.3mph 156.7km/h) *

Misc Remarks: MAX FL TEMP 17 C 118 / 12 NM FROM FL CNTRMAX OUTBOUND SFMR SFC WIND 61 KT SE QUAD 10:01:30Z;

Hybrid nature shown well on regional radar. Hurricane bands rotating into large rain shield on W side...

Yeah, and that's creating deformation bands from hell. Look at the radar now, oriented S-->N, at the brighter areas where there is enhancement once the bands rotate across the Chesapeake...Any pros want to chime in to discuss why that's happening?

Strong 700mb frontogenesis in that region
