Rocking our way with zonal flow.

 

 

Yeah I don't see big cold...at least early on. That could obviously change the deeper into the month we go...but for now, its going to be transient airmasses and not really much potential for early arctic intrusions with a flat flow.

 

That's fine with me, I don't really need frigid temps on 10/8...they might be more "interesting" after 10/15 where at least the interior can try for a snow event out of it.

Yeah agree. I don't see Rocktober happening early on..maybe that changes deeper into the month.

some GEFs hints at a stronger phase 5/6 MJO which would lead credence to Raleighs trough in our hood keeping us cooler but not much else

 

Well we probably will have some transient stuff..I mean the flow never is constantly zonal...just don't see a big change to cool at this time. Maybe this changes going forward.

I was wondering what was up with BDL's obs coming in at 65° last how and they dropped 5° in the past hour to 60°.  That seems a bit much but that's what they recorded:

 

http://www.erh.noaa.gov/box/obs/BDLobs.html

 

Currently an unremarkable 53° here.

Sunset and decoupling...what's wrong with 5F in an hour?

Sunset I can understand and there were some stations that dropped 10° in that hour but BDL stayed warm and was the only station around it to drop 5° that hour.  It was just odd that all the other stations at the time were around 60°, include the more urban HFD station but BDL stood out at 65°.  There was nothing else to talk about so it was one of those what's up with that questions.

 

Looks like it's 42° here now.  So much for a forecasted low in the upper 40s.

 

CEF looks like the coldest ASOS in SNE at 41°.

Here's the last forecast posted which was updated at 0115 and was true on the hill tops but other readings around were already in the 40s and now in the low 40s:

What did the point and click forecast show? The ZFP is basically a legacy product at this point generated by computer with the same old spatial resolution issues it has always had (there will be times when it doesn't properly cover the temperature range of every hilltop and valley location). Sometimes it gets manually adjusted before issuance, many times not.
