A partly cloudy, chilly, breezy Sunday and sunny, milder Monday update for West Rockville Maryland for Sunday April 29 and Monday April 30, 2018
I had a variety of curve balls thrown at me on Sunday and went to bed very early for me so I did not send a report out for Sunday till this combined Sunday/Monday effort right now. Sorry about that. Information will be necessarily condensed. No rain fell as the month of April finished out dry, along with the start of a warm up as we head into the month of May. It appears that Mother Nature is turning on the heat this coming first week of May, as high temps will be hitting at least 80° most of the days of this week. Sunday was a blustery, chilly day, with plenty of afternoon cumulus and stratocumulus covering the sky a good part of the time. Temps held in the low 50s after starting out in the low 40s. Overnight into Monday skies cleared, the wind lessened and temps dropped into the upper 30s by sunrise. Monday was a milder day, with full sun and temps approaching the 70° mark. The Sunday maximum temperature was only 53.4 @ 1531 while the Sunday minimum temperature was 42.4 @ 0638. The Monday maximum temperature warmed up to 69.5 @ 1649 while the Monday minimum temperature was 38.9 @ 0703. The dew point temperatures remained quite low both days, ranging from a low of 22° on Monday @ 0538 and 31° on Sunday @ 0504 up to highs of 40° on Sunday and 34° on Monday, both recorded at midnight (0000). The barometric pressure climbed from a low of 29.97″ on Sunday at 0000 up to a high of 30.25″ on Monday at 0824. The intermediate high reading on Sunday was 30.19″ at 2136 while the intermediate low reading on Monday was 30.06″ at 1854. Relative humidity had both its extreme values on Monday, ranging from a high of 72% at 0011 and a low of 20% at 1549. Intermediate highs and lows on Sunday were a high of 70% at 2351 and a low of 48% at 1535.

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.
As of 0642 Tuesday, 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:
Clear, not as cool and calm – looks to be a nice day for a Tuesday !!
Station Relative Location Temp RH DP BP Wind High/Low temp
VP2 Ground 46.5° 61% 34° 30.19″R NA 69.5/38.9 (Monday)
53.4/42.4 (Sunday)
The total precipitation in the cocorahs gauge was 0.00″ through midnight Monday. The VP2 tipping bucket rain gauge under my balcony recorded 0.01″ through midnight Monday.
Sunday and Monday’s precipitation was 0.00″
April precipitation 3.57″
April snowfall 0.0″ (will be reported till the end of April – I just brought in my snowboard Friday night)
The seasonal snowfall total is 12.0″.
Year-to-date precipitation total is 11.74″
140° from station 70/38 (Monday) Missing for Sunday
The Lakewood rain gauge reported 0.00″ of precipitation on Sunday and Monday. However, it is now reporting a total of 3.93″ of precipitation for April and a 2018 year-to-date (YTD) amount of 14.81″. 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 the Lakewood precip values are estimated/adjusted from radar.At 2400 obs Monday night the temperature from the VP2 was 57.6 RH 36% BP 30.12″R DP 30.8
Clear, not quite as cool, dry at 2400 Good morning from the clear, not as cool, and dry home of the snowless walrus early on this Tuesday at the start of the new month of May. Today’s featured image shows a few flowering trees from across the street at this time at the start of May. If I think about it, I will take a similar picture of these trees in a month at the start of June.
