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 has been producing erratic values at times so should not be used except for general precipitation timing. For example during our big snowstorm back in mid-January the snow didn’t melt at all during the storm, and only started to record precipitation amounts a few days later when the sun
and above freezing temperatures started to melt the snow.
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. I also use a snow stake outside my balcony window to get an idea on how much snow has fallen (while it is snowing) and how much snow is on the ground.
Sunday is now cloudy with highs possibly reaching 40° later with lows this morning in the upper 20s when it mostly clear. Rain is on the way, supposed to start sometime this afternoon.
Monday should be cloudy and milder, with highs in the upper 40s and lows in the mid 30s.
Tuesday should be partly cloudy and dry with highs in the low 40s with lows in the upper 20s.
Wednesday should be our next good snow chance, with highs in the mid 30s and lows in the low 30s. Still might mix with rain at times especially towards evening as warmer air aloft works into the system. Stay tuned on this one.
Thursday should be cloudy and milder with a good chance of more rain. Highs should reach into the low 50s, lows around the freezing mark.
Friday should be cloudy and cooler with a chance of more rain. High temps should be in the mid 40s with lows once again around the freezing mark.
Midnight Saturday night found the temperature at 32.9°, relative humidity 64%, pressure rising at 30.07″ and the dew point at 22° under clear skies.

Good afternoon from this snowless walrus on this cloudy Sunday. Have a nice President’s Day weekend!
