Saturday was partly cloudy, a tad milder PM but still freezing in the early AM (through 3/25 21 of 25 days have had freezing mins this March), with the snowpack melted off to 0 from the strong March sun. Today’s feature image is looking N from my balcony from Saturday afternoon. It was also breezy at times, creating wind chill temps in the 20s and 30s early and late in the day. Temperatures rebounded after the sub-freezing 30° minima to reach the mid-upper 40s by mid-afternoon. A patchy trace snowpack early melted off completely by the end of the day. The Saturday maximum temperature from the VP2 (47.0°) was recorded at 1531 while the minimum temperature (29.5°) was recorded at 0702. Dew point temperatures remained low and very similar to yesterday, ranging from a low of 21° at 0653 up to a high of 26° a bit later at 1139. Relative humidity values were also about the same as yesterday (72% – 40%). Barometric values rose a bit today, ranging from a high of 30.26″ at 0753 down to a low of 30.12″ later at 1656.

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.

Overnight Saturday into Sunday skies had cleared off late with temps dropping off through the 30s into the upper 20s by sunrise (28.4° to be exact at 0753). Turns out the VP2 rain gauge still had more melted runoff on Saturday that totaled an additional 0.07″ for the day. That brings me really close (combined Tuesday, Thursday – Saturday VP2 rain gauge total of 1.03″) to the 2 day total from my cocorahs gauge of 1.01″. Partly cloudy skies on Sunday with highs in the mid 40s and lows in the upper 20s. Sunny skies on Monday, with highs in the upper 40s and lows in the upper 20s. Tuesday should feature highs in the upper 40s under mostly cloudy skies and lows above freezing (upper 30s). Wednesday should be cloudy but with a 50 POP for PM showers, highs in the upper 50s and lows in the upper 40s. On Thursday more showers are expected (70 POP) with clouds and slightly milder temps, with highs around 60° and lows in the low 50s.

On the Channel 4 weather website at 1041 radar is showing a clear 4 state Mid-Atlantic region. Closest precipitation are some showers offshore of the Carolina coast and some thunderstorms over central Georgia at this time.

As of 1041, 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 WXBug station are as follows:

Clear (with some cirrus and cirrocumulus moving in this morning after sunrise) and remaining cold, with all natural snow remnants melted off. Still breezy at times.
