Friday the 13th had no meteorological shenanigans for my area, as the typical altostratus overcast lessened and only lasted into the mid AM, then turned mostly sunny with scattered high clouds and warmer temperatures soaring well into the 80s as had been predicted all week. However, it did get hot in my apartment so for the first time this year, I put the A/C on to cool things down. The Friday maximum temperature from the VP2 (83.9°) was recorded at 1729 while the equally balmy Friday minimum temperature (62.1°) was recorded at 0640. Dew point temperatures continued to rise also, ranging from a low of 44° at 0414 up to a high of 51° much later at 2259. Relative humidity values lowered from yesterday (55% – 27%) . Barometric values lowered a bit today, ranging from a high of 30.01″ at 0828 down to a low of 29.85″ at 1807.

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 Friday into Saturday skies clouded up overnight once again with a partial altostratus overcast that really kept a warm ceiling on the temperatures, as they failed to drop below 60° for the warmest night of April (62.1° actual reading), and warmest night of 2018, surpassing the 61.2° minimum temperature reading back on February 21. Saturday morning had an even warmer launching point, as the morning low was only 64.6° at 0655. Saturday should be mostly sunny and warm once again, with highs in the low 80s and lows around 60° once again. Sunday should cloud up and cool off into low 60s highs, about 50° for lows, and an 60% POP for showers and possible thunderstorms. Morning rain (80 POP) and cloudy on Monday and even cooler, with highs in the upper 50s and lows in the upper 30s. Tuesday should be mostly cloudy and even cooler with highs in the low 50s and lows again in the upper 30s. Wednesday should start to warm up under mostly sunny skies, with highs in the mid 60s and lows in the upper 40s.

On the channel 4 weather radar website at 0954 shows rain showers and embedded thundershowers running along a slow-moving cold front through the midwest, running from Michigan (as snow actually) SSW to LA and especially MS at this time. This area of rain should be arriving in our area sometime on Sunday.

As of 0954, 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:

Mostly sunny with some faint, weak scattered cirrus, warm and still dry.

Station Relative Location Temp  RH   DP     BP       Wind High/Low temp Friday
VP2             Ground        72.2° 58% 56° 29.98″R   NA     83.9/62.1

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

Friday’s precipitation was 0.00″
April precipitation 0.17″
April snowfall 0.0″ (will be reported till the end of April)
The seasonal snowfall total is 12.0″.
Year-to-date precipitation total is 8.34″

WX Bug Lakewood 4500 ft, 72 51 53 30.02″S SSW 1 G SW 15
                            140° from station                  85/62
The Lakewood rain gauge recorded 0.00″ of precipitation on Friday. 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.

At 2400 obs Monday night the temperature from the VP2 was 73.7 RH 46% BP 29.92″S DP 51.6
PCldy, warmer, dry at 2400

Good morning from the mostly sunny, warm, dry home of the snowless walrus on this Saturday.
