Saturday was mostly sunny and mild. The temperatures ranged from the low 50s in the late morning sliding down slowly to the mid-upper 30s by late evening. A picture of cirrostratus/contrails from the rain gauge around sunset on Saturday is today’s featured image.

The maximum temperature was 52.0° at 0949.

The minimum temperature was 37.1° at 2359.

Dew point temperatures ranged from a high of 49° @ 0000 down to a low of 31° @ 2357.

Relative humidity values ranged from a high of 97% @ 0000 down to a low of 60% @ 1215.

Barometric pressure ranged from a low of 29.93″ @ 0005 up to a high of 30.26″ @ 2023

No rain fell on Saturday. December 2018 still has 6.70″ of precipitation (liquid water equivalent) for the month. The year-to-date precipitation is still 65.42″.

My current online data (except for rainfall/snowfall – use the cocorahs link shown below for that dataset) is showing regularly on Weather Underground. My data is posted there every 5 minutes. My ID is KMDROCKV200 and my station is called “Gardens of Traville.” Data is online, normally just about in real-time now as it is being updated on a 5 minute interval. The web address for my data on weather underground is:
https://www.wunderground.com/personal-weather-station/dashboard?ID=KMDROCKV200

I contribute my precipitation data daily to CoCoRaHS as Rockville 2.8 WNW, Station ID MD-MG-115 on https://www.cocorahs.org/

Please remember that Weather Underground precipitation data reflects what is recorded automatically through the tipping bucket VP2 gauge, just as it does on WxLink 2.0. The tipping bucket is producing erratic values so should not be used save for general precipitation timing. For example recently the bucket recorded 5.62″ for the day, clearly a significantly higher amount when compared to my 4 inch gauge total that day (3.24″). I actually use the data I post
to CoCoRaHS from my 4 inch CoCoRaHS gauge I read manually as my “official” precipitation total each day.

Sunday looks to cool off a bit with partly cloudy skies and highs in the upper 40s and lows in the low- mid 30s.

New Year’s Eve Monday looks cloudy/rainy with temps in the mid-upper 40s to close out the year in typical wet style we have had much of 2018.

New Year’s Day Tuesday looks to start 2019 on a mild note with highs in the upper 50s and lows in the upper 30s under partly cloudy skies.

Wednesday looks cloudy with highs in the mid 40s and lows in the mid 30s.

Thursday looks cloudy/rainy, with highs in the low-mid 40s and lows in the mid 30s.

Saturday’s midnight observations include a temperature of 37.1°, relative humidity 78%, barometric pressure 30.25″ and steady, with a dew point of 31.0° under partly cloudy skies.

Currently at 0802 the temperature is 35.9°, dew point temperature 32°, relative humidity 87%, and the barometric pressure at 30.29″ and rising under cloudy skies.

Good morning from the Walrus on this partly cloudy Sunday morning.
