Clear/sunny early through mid AM, temps bottoming out in the mid 20s, then increasing clouds the rest of the daylight hours, with temps reaching the upper 30s, then cloudy during the evening as Wednesday’s snowstorm was moving closer, with temps lowering down into the mid 30s by midnight observation. 

The maximum temperature was 38.4° at 1541.

The minimum temperature was 26.2° at 0712.

The dew point temperatures ranged from a high of 22° @ 0000 down to a low of 10° @ 1145.

The relative humidity values ranged from a high of 67% @ 0125 down to a low of 31% @ 1625.

The barometric pressure ranged from a low of 30.45″ @ 0000 up to a high of 30.67″ @ 1030.

Tuesday had no precipitation. My February monthly total is still 1.86″ with my year-to-date total at 5.44″ for 2019.

No snow/sleet fell on Tuesday. My year-to-date snowfall is still 16.7″ with the seasonal total at 18.8″.

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.

Wednesday has been cloudy and cold with morning snow that changed to a mix by mid-day, and then rain by late afternoon/evening, with highs in the mid 30s and lows in the mid 20s. A WINTER STORM WARNING has been in effect since early Wednesday morning and will not expire till 2200 Wednesday evening. I have a preliminary snow total through mid-day of 5.5″. See featured image for a glimpse at the morning snow, with the promise of more in Wednesday’s post. 

Thursday should be partly cloudy and milder. Highs should reach the low 50s, lows around the freezing mark.

Friday should be cloudy and cooler. High temps should be in the mid 40s with lows once again around the freezing mark.

Saturday looks cloudy and cooler with a good chance for rain with temps around 40°.

Sunday looks cloudy and rainy during the earlier part of the day, but with partial afternoon sun temps could reach the mid 60s. Lows around the freezing mark.

Midnigh Tuesday night found the temperature at 33.7°, relative humidity 41%, pressure falling at 30.61″ and the dew point at 12.5° under a high cloud overcast. 

Currently at 1518 the temperature is 31.1° under cloudy (stratus) skies with some light freezing drizzle at times, relative humidity at 92%, barometric pressure falling at 30.36″, and the dew point at 29°. Still 5.5 inches of snow on the ground according to my snow stake. 

Good afternoon from the now snowywalrus on this cloudy, formerly snowy Wednesday. Be watching for several snowy pictures from out my balcony over the next few days. See the featured image in today’s post for a first peek at Wednesday’s snow. It was taken during a brief burst around 1130 just before the snow lessened and changed over to a mix of sleet, freezing rain and snow.
