Sunday started out cloudy and slightly wet with occasional light showers early but warmed up into the lower-mid 60s through the early afternoon. Increasing SE breezes through the early afternoon veered more northerly/ northwesterly thereafter and advected gradually colder air and storm clouds with moderate rain, higher, steadier wind gusts during a very interesting evening. Temperatures warmed from the not so chilly early AM minimums in the 50s up to the lower-mid 60s in the mid afternoon. The temps then dropped steadily the rest of the day, through the 50s and into the lower mid 40s before midnight obs. Winds continued to increase, peaking out around 35 MPH. Dew points rose at first today, hitting into the 60s through early afternoon, but then dropping into the low 40s by late evening. At 0845 we have a lifting cloud deck, now dry but still breezy. Temperatures are in the mid 40s with dew points in the upper 30s. The Sunday minimum temperature from the VP2 (44.2°) was recorded at 2350 while the maximum temperature (64.2°) was recorded at 1317. Dew point temps ranged from 63° down to 43°. Relative humidity values predictably rose today (98% – 88%). Barometric values lowered tremendously today with our big rainstorm, ranging from a high of 29.81″ at 0000 down to a low of 29.20″ at 2119 (please see plot below) . A really dynamic rapid drop and rise change in pressure was associated with this lowest barometer reading of the day. Pressure dropped .08″ in about 10 minutes down to that lowest 29.20″ reading then rose up .06″ the next 10 minutes to 29.26″. (see plot please)
Here is my actual data. This is the largest image size I can seem to generate here for now. I have tried to label a few key columns that more directly pertain to the barometer pressure drop subject at hand.

Remember now you can get the VP2 data on Weatherlink. You can access the data through http://www.weatherlink.com/user/walrusman444. I am also now on
weather underground. My ID is KMDROCKV200 and my station is called “Gardens of Traville.” Data is online, normally just about in real-time.
Our rainy cloud deck has lifted and drying out has started. We did not lose power here but other locations in the area were not so fortunate, with flooding in other parts of the state, mostly to the east. Towards the end of the storm as the colder air moved in snow fell in the mountains of western Maryland and West Virginia, including 8.4″ of snow as of 0700 at Canaan Heights WV at 3715′. The temperatures are currently in the mid 40s here at my station as of 0845. Slowly decreasing winds this morning will cause our wind advisory for our area to end in a few hours at 1000. Monday should cool further with highs in the mid 50s and lows in the lower 40s, but with partly cloudy, breezy skies at times. Halloween Tuesday does look to stay cool but dry under sunny skies with highs in the upper 50s and lows in the mid 30s for reasonably good “Trick or Treat” weather. Wednesday looks to be cloudy and cool but dry with highs in the mid 50s and lows in the mid 40s. Thursday should be partly cloudy and dry with highs warming up to the 70° mark and lows in the low 50s.
On Weatherbug at 0845 the radar is showing our rain has moved off to the north and east, over coastal NJ and NY and much of New England and upstate New York at this time. Flooding rains are occurring in selected locations in this area.
As of 0845 EDT, the data from the VP2 (coming from the ground radiation shield about 4 feet off the ground just under and out from the balcony) and the Lakewood WXBug station are as follows :
Station Relative Location Temp RH DP BP Wind High/Low temp today
VP2 Ground 46.0 74 38 29.65R+ NA 64.2/44.2
There was 0.96″ of rain in the cocorahs gauge on Sunday. The VP2 tipping bucket rain gauge under my balcony recorded 1.07″ of rain on Sunday, the higher amount probably attributable to a wind swirling effect or excessive moisture dripping down from the closeby pine tree. A max rain rate of 0.86″/hour was recorded at 1847. 0.23″ has been recorded in the VP2 gauge since midnight, with no more likely to come.
October precipitation is now 2.65″.
Year-to-date precipitation total is now 36.21″

The Lakewood rain gauge recorded a ridiculously low 0.02″ amount of rain through midnight on Sunday. I don’t know what went wrong. I am hoping this will be adjusted. If so, I will post an update.
Temp from the VP2 at 2400 was 44.1 RH 95% BP 29.29R DP 42.8. Cloudy with light rain and cool at midnight .
Good morning from the partly cloudy, cooler and drying out Walrus early on this Monday.
