Thursday turned sunny in a one day break between rain systems on Wednesday and now early on Friday. We had seasonable temperatures in the mid upper 60s and lows in the mid 40s with light winds, but with increasing clouds late in the PM ahead of our Friday inclement weather. The Thursday maximum temperature was 67.4 @ 1707 while the Thursday minimum temperature was 46.0 @ 0616. The dew point temperatures lowered today, ranging from a high of 53 @ 0000 down to a low of 36 later @ 1719. The barometric pressure remained relatively low again today, reaching its daily minimum value of 29.76″ at 0000 up to its high for the day of 29.90″ a bit later @ 1022. Relative humidity lowered throughout the day, peaking early at 84% @ 0000, then gradually lowering to the daily low of 32% later @ 1719.

I am posting daily to weather underground. My ID is KMDROCKV200 and my station is called “Gardens of Traville.” Data is online, normally just about in real-time. The web address for my data on weather underground is: https://www.wunderground.com/personal-weather-station/dashboard?ID=KMDrockv200#history/ I contribute daily to cocorahs as Rockville 2.8 WNW, Station ID MD-MG-115 on https://www.cocorahs.org/ Please remember that Weather Underground does not report snow data, and reflects what is recorded automatically through the tipping bucket VP2 gauge. I use the data I post to cocorahs as my “official” precipitation total each day.

I hope my supplemental data I published yesterday came out for you and for some of you was useful in filling in the holes from the time of my “hiatus”. On Thursday I continued to catch up with my activities, weather or otherwise. I finally got all my March reports and data out on email and on weather together and now await the end of April and the start of collecting and entering that data set. hopefully in a more timely fashion. 

Thursday turned sunny with seasonable temps but with increasing clouds late and overnight helping to eventually turn conditions into a rainy early AM on Friday. My tipping bucket must be blocked as it is only reporting 0.02″ from midnight till 0800, but a very reliable closeby weather underground station at Muddy Branch Park recorded 0.63″ of rain since midnight, with most all of the rain falling between 0330 and 0630 so far. My official Friday total will be determined later at the close of the day when I read my cocorahs gauge at midnight. Overnight into Friday has shown a drier turn over the past hour or so, with the radar becoming clear to our south, which was the direction I have been getting the rain from. Friday will remain cloudy with still officially a 70 POP for AM rain, with highs in the low-mid 60s and lows around 50°. Saturday and Sunday look to be partly (Sat) to mostly sunny (Sun), highs on Saturday in the low 70s and in the mid 50s on Sunday, lows both nights in the upper 30s. There is a 60% POP for PM showers on Saturday as another front passes through. Monday should be sunny with highs in the mid 60s and lows in the mid 40s. Tuesday at the start of May should start warming up, with highs in the mid 70s and lows in the low-mid 50s. Rumor has it that later in the week, coinciding roughly with the beginning of May, our first May 80s heat wave will occur. I hope not but it is inevitable unfortunately.

On the Channel 4 radar at 0805 the rain showers are still in the region, but moving north and northeast and will be lightening in my area most of the morning.

As of 0805 Friday, 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 WX Bug station are as follows:

Mostly cloudy (stratoform overcast), cool and still wet.

Station Relative Location Temp RH DP BP Wind High/Low temp Thursday
VP2               Ground         52.5° 92% 50° 29.79″F NA 67.4/46.0

The total precipitation in the cocorahs gauge was 0.00″ through midnight Thursday. The VP2 tipping bucket rain gauge under my balcony recorded 0.02″ through midnight Thursday, probably due to “belated drip-through vegetative blocking”. Since midnight it has severely under-reported a total of 0.02″ of rainfall to the current time. It may very well start to catch up later as the water starts seeping through the probable blockage.

Thursday’s precipitation was 0.00″
April precipitation 2.96″
April snowfall 0.0″ (will be reported till the end of April)
The seasonal snowfall total is 12.0″.
Year-to-date precipitation total is 11.13″

WX Bug Lakewood 4500 ft, 51 100 51 29.81″R WNW 3 G WSW 10
                              140° from station                       70/44
The Lakewood rain gauge reported 0.00″ of precipitation on Thursday. It is now reporting a total of 3.25″ of precipitation for April and a 2018 year-to-date (YTD) amount of 14.13″. Since midnight up through the current time 0.16″ has been recorded. I still believe at times the great disparity between the Lakewood WX Bug station precipitation amount total for the month and year and my cocorahs gauge based data is that Lakewood precip values are estimated/adjusted from radar.

At 2400 obs Wednesday night the temperature from the VP2 was 59.8 RH 53% BP 29.86″F DP 42.6
Cloudy, mild, getting ready to rain soon but still dry at 2400

Good morning from the cloudy, cool, and wet home of the snowless walrus early on this Friday.
