Tuesday was mostly clear/sunny, cooler in the AM, milder in the PM, with high, contrail-laden clouds much of the morning (see featured image for some more contrails observed Tuesday morning), still very dry but with winds abating from yesterday.  Temps reached highs around 50° for highs after early morning mins around the freezing mark. Pretty close to normal temps for this time of year.

The maximum temperature was 50.2° at 1501.

The minimum temperature was 31.9° at 0703.

The dew point temperatures ranged from a low of 8° @ 0035 up to a high of 22° @ 2115.

The relative humidity values ranged from a low of 30% @ 1355 up to a high of 58% @ 2340.

The barometric pressure ranged from a high of 30.46″ @ 0830 down to a low of 30.32″ @ 1430.

Tuesday had no precipitation. My February monthly total is still 3.44″ with my year-to-date total at 7.02″.

No snow/sleet fell on Tuesday. My February total snowfall is still 7.3″ with the seasonal total at 24.3″.

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 my 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. This scenario also developed nicely last Thursday as the sun melted most if not all of the snow in the tipping bucket rain gauge. 0.86″ passed through the tipping bucket all day Thursday even though no precipitation fell from the sky.

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 as I did this past Wednesday.

Wednesday has been a  lot cloudier and cooler than predicted, with temps holding in the 30s all day and a cloud deck predominating most all of the day.

Thursday should be partly cloudy with high temps in the low 40s, lows in the upper 20s. 

Clouds with a bit of light snow expected to fall on Friday morning, with highs in the upper 30s and lows in the low 30s. Right now the latest prediction is for 1-3″ to fall. 

Saturday should be cloudy and milder, highs around 50° but with the temp dropping late, lows in the upper 20s.

Sunday should be cloudy and cooler with highs in the mid 40s and lows in the upper 20s with rain expected. 

Monday will clear out under mostly sunny skies, turning colder with highs in the mid 30s and lows in the upper teens. 

Midnight Tuesday night found the temperature at 34.9°, relative humidity 58%, pressure falling at 30.42″ and the dew point at 21.6° under a partly cloudy sky.

Currently at 1827 the temperature is 37.1° under cloudy skies, relative humidity at 74%, barometric pressure falling at 30.11″, and the dew point up to 30°.

Good evening from the clouded over walrus on this dry Wednesday.
