Tuesday turned mostly sunny and not as cold after some early AM light fog. Milder temps were found particularly on the max side, as our big weekly warmup commenced. Each day this week will be progressively warmer with 80 max temps reached by Friday. The Tuesday maximum temperature from the VP2 (50.6°) was recorded at 1656 while the Tuesday minimum temperature (34.5°) was recorded at 0657. Dew point temperatures rose a bit today, ranging from a high of 36° at 0003 down to a low of 22° much later at 2254. Relative humidity values were roughly the same as yesterday (94% – 35%) . Barometric values followed different patterns today, not strong ones with not much variability, ranging from a high of 30.26″ at 1048 down to a low of 30.16″ at 1730.

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 Tuesday into Wednesday skies clouded up overnight with a high, thin altostratus overcast. I had light fog early Tuesday morning but none early Wednesday morning. Temps lowered to the mid-upper 30s, well above the freezing mark. Partly cloudy (AM Clouds/PM Sun) and a bit milder on Wednesday with highs in the mid 50s and lows in the low 40s. Thursday should be partly cloudy with highs in the low 70s and lows in the mid 50s. Friday the 13th should be partly cloudy and warmer, with highs around 80° and lows in the upper 50s. Saturday should be very similar, but a few degrees even warmer. Sunday should cloud up and cool off into mid 60s highs, mid 50s lows, with a 50% POP for rain showers.

On the channel 4 weather radar website at 0832 still shows light snow over eastern WV, much of PA, and northern MD with rain in NE Maryland up around parts of the Baltimore area and NE towards DE at this time. Much of this action is probably not reaching the ground, or if it is, in very light amounts.

As of 0832, 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:

High altostratus overcast, not as cold, still basically dry.

Station Relative Location Temp  RH    DP     BP      Wind High/Low temp Tuesday
VP2          Ground           42.0° 58%  28° 30.24″R   NA    50.6/34.5

The total precipitation in the cocorahs gauge was 0.00″ through midnight Tuesday. The VP2 tipping bucket rain gauge under my balcony recorded 0.00″ through midnight Tuesday.

Tuesday’s precipitation was 0.00″
April precipitation 0.17″
Tuesday’s snowfall was 0.0″
April snowfall 0.0″
Snow on ground 0 (reported to the nearest half-inch)
The seasonal snowfall total is 12.0″.
Year-to-date precipitation total is 8.34″

WX Bug Lakewood 4500 ft, 41 57 26 30.21″R ESE 2 G ESE 3
                            140° from station                   51/33
The Lakewood rain gauge recorded 0.00″ of precipitation on Tuesday. It is reporting a total of 0.43″ of precipitation for April and a 2018 year-to-date (YTD) amount of 11.30″. I think the great disparity between the Lakewood WX Bug station precipitation amount total for the month and year and my cocorahs gauge based data is that Lakewood precip values are estimated/adjusted from radar data.

At 2400 obs Monday night the temperature from the VP2 was 42.5 RH 45% BP 30.23″R DP 22.6
PCldy, milder, dry at 2400

Good early morning from the cloudy, not as cold, but dry home of the snowless walrus on this Wednesday.
