Mostly clear, cold early AM, moderating by mid-afternoon with increasing clouds, cloudy, cold evening with light snow developing in the later part of the evening. Temps started out around the 20° mark, rising to the upper 30s by mid-afternoon, then dropping off to the freezing mark by late evening with the snow. 

Sunday’s maximum temperature was 38.0° at 1508. 

Sunday’s minimum temperature was 20.5° at 0650. 

Sunday’s dew point temperatures ranged from a low of 10° @ 0000 up to a high of 29° @ 2334.

Sunday’s relative humidity values ranged from a low of 43% @ 1517 up to a high of 91% @ 2342.

Sunday’s barometric pressure ranged from a high of 30.77″ @ 0431 down to a low of 30.36″ @ 2345.

Sunday had 0.03″ of melted precipitation. My February monthly total is now 0.23″ with my year-to-date total now at 3.81″ for 2019.

0.4″ of snow fell late on Sunday. My year-to-date snowfall is now 16.5″ with the seasonal total at 18.6″.

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.

Monday and Tuesday should have a mixed bag of precipitation continuing, esp in the early morning hours, with a tendency for just plain rain later in the day, esp on Tuesday. Temps will moderate through the 30s into the 40s by the afternoon.

Sunny skies on Wednesday with highs in the low 40s and lows in the upper 20s. Thursday and Friday should be warmer with highs in the 50s, with rain on Friday and clouds both days, lows in the 40s on Thursday and 30s on Friday as cooler air comes in for the weekend. 

Midnight Sunday night found the temperature at 31.3°, light snow falling, relative humidity 91%, pressure falling at 30.36″ and the dew point at 29.0° under cloudy, snowy skies.

Currently at 0633 the temperature is 32.3° under cloudy skies (with light rain/light freezing rain falling) , relative humidity at 94%, barometric pressure now steady at 30.28″, and the dew point at 31°.

Good morning from the somewhat wet walrus on this cloudy, rainy Monday.
