Overnight early Tuesday morning persisted with Monday’s cloudy, chilly, damp conditions with dense fog developing towards sunrise. Rain was light, with a lot of drizzle accompanying the fog. Gradually after mid-day the cloud cover began to lift, and breezes picked up as the cold front rushed in, and whisked the fog and dampness away throughout the afternoon.  Temps held in the 30s all day, however, always above freezing so there were no issues of icy streets and the little bit of snow that was left from yesterday completely melted by mid-day, as temperatures had gradually climbed through most of the 30s. Dew points rose to the upper 30s by mid-afternoon, but dropped to around 30 by late evening around midnight observation time. 

The maximum temperature was 39.2 degrees at 1833.

The minimum temperature was 34.2 degrees at 0008.

The dew point temperatures ranged from a high of 38 degrees @ 1556 down to a low of 30 degrees @ 2357.

The relative humidity values ranged from a low of 60% @ 0000 up to a high of 95% @ 2345.

The barometric pressure ranged from a high of 30.14 inches @ 0003 down to a low of 29.70 inches @ 1345.

The highest daily peak wind gust recorded across the street on the roof of the new USG building was 27 MPH at 1827 from the NW.

There was 0.17 inches of precipitation on Tuesday. My December monthly total precipitation is now 2.57 inches.

There was no snow on Tuesday. No snow on the ground at my midnight observation time. My seasonal total snowfall is 1.4 inches.  The year-to-date precipitation total is 45.68 inches.

My current downstairs station data is now 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, available in real-time as it is being updated on a 5 minute interval. The web address for my data on weather underground is  https://www.wunderground.com/dashboard/pws/KMDROCKV200 .

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

Please remember that my 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 has been producing erratic values on most days (when I have had rain that is) so should not be used except for general precipitation timing.

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.

Tuesday was another busy day, mostly during mid-day. Mike took me to Kaiser for a 2 PM Podiatry appointment to get my toenails cut. They were running late so a 1/2 hour appt turned into more like an hour appt, with transportation time to and from adding another half hour. So I got back to my apartment around 1530, and had a late breakfast of a toasted everything bagel/egg and cream cheese sandwich and coffee. I caught up on the phone with my daughter Tracy, and of course more weather talk with Ray, and later more weather and other business talk with Marty.  I cleaned up a bit and tied up some loose ends in anticipation of Marty’s visit tomorrow to deliver my new CPU for my computer system, and other assorted activities that need to be done with the coming winter. I hada big tossed salad for dinner, including spring greens, radishes, mushrooms, hot pepper and cottage cheese, sliced zucchini, croutons and a variety of salad dressings. 

Wednesday should be mostly sunny and cold, with highs in the upper 30s and lows around 30.

Thursday should be sunny and colder, with most likely our first high temperature of the season at or below the freezing mark, with lows around 20.

Friday and Saturday look sunny to partly cloudy with a bit of moderating temperatures, highs in the upper 30s and lows in the low 20s.

Sunday should moderate a bit more, under partly cloudy skies, with highs in the mid 40s and lows around 30.

At Midnight Tuesday, clearing skies with a temperature of 37.0 degrees, relative humidity 96%, pressure rising at 29.93 inches with a dew point temperature of 30 degrees.

Currently at 0452 EST Wednesday the temperature is 31.5 degrees under mostly clear, dry skies, relative humidity at 73%, barometric pressure rising at 30.00 inches, and the dew point temperature at 24 degrees. Winds are averaging 7 MPH over the past 10 minutes from the NW. Peak wind gust since midnight has been 20 MPH from the NW at 0312.

Good morning from the walrus on this clear, somewhat blustery early Wednesday. Tonight’s featured image is of the last quarter moon through rolling broken clouds when I went out to the rain gauge to measure Tuesday’s precipitation.
