Friday was a cloudy, cooler, wet day with persistent light showers (0.22″) off and on most of the day. Temperatures held mostly in the 60s all day after initial low 70s in the very early AM. Overnight into Saturday skies were cloudy, with temps dropping into the mid 60s by sunrise, covered by a low stratus deck of fog and low clouds. Temperatures should warm up into the lower 80s with perhaps some sun amongst the clouds, but with an 80 POP for PM thunderstorms. The Friday maximum temperature was 74.6° @ 0000, while the Friday minimum temperature was 64.7° @ 2228. The dew point temperatures remained in the 60s all day, ranging from a high of 70° @ 0000 down to a low of 62° @ 2050. The barometric pressure rose a bit from Thursday’s values – the lowest value being 29.81″ @ 0317 up to a high of 29.92″ @ 1253. The relative humidity values rose some from yesterday’s, ranging from a low of 83% at 0019 up to a high of 93% at 1032.

Remember now you can get the VP2 data on Weatherlink. You can access the data through http://www.weatherlink.com/user/walrusman444 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 precipitation data reflects what is recorded automatically through the tipping bucket VP2 gauge. I actually use the data I post to cocorahs from my 4″ cocorahs gauge I read manually as my “official” precipitation total each day.

Friday featured clouds and lightly rainy skies most of the day, with cooler temps, mostly in the 60s. Saturday should be partly cloudy with an 80 POP for PM thunderstorms, highs in the mid 80s and lows in the upper 60s. Sunday should be partly cloudy with highs in the upper 80s and lows in the mid 60s. Partly sunny on Monday with highs in the low 80s and lows around 60°. Tuesday should be partly cloudy with highs around 80° and lows in the mid 60s. Wednesday should be partly cloudy with highs in the low 80s and lows around 70° with a 30 POP for an isolated thunderstorm.

At 0915, NBC4 radar is showing a small area of storms and showers heading NE out of the Winchester VA area into eastern WV around Martinsburg and into western Maryland in the Hagerstown area. Storms and showers generally have moved into northern parts of PA and moving NE and away from my location.

At 0915, 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 WX Bug station are as follows:

Cloudy (slowly lifting stratus from earlier moderate fog) , cool and damp

Station Relative Location Temp  RH   DP      BP   Wind High/Low temp on Friday
VP2              Ground       67.5° 97% 67° 29.86″S NA    74.6°/64.7°

The total precipitation in the cocorahs gauge was 0.22″ through midnight Friday. The VP2 tipping bucket had 0.13″. I think the generally greater amount in the VP2 tipping bucket rain gauge recently has been at least partially due to its proximity to a dense evergreen tree that frequently drips down and then blows the “catch” into the gauge. I mostly use this gauge to tell me when and how hard it rained. So far today (since midnight) it has recorded 0.08″ of rain through 0915.

Friday’s precipitation was 0.22″
June precipitation 3.67″
Year-to-date precipitation total 22.09″

WX Bug Lakewood 4500 ft, 67° 100% 67° 29.86″S E 4 G E 4
                            140° from station                      73°/63°
The Lakewood rain gauge recorded 0.18″ of rain on Friday. So far on Saturday an additional 0.10″ has been recorded. June total precip is now being reported as 7.51″ with the 2018 year-to-date (YTD) amount now at 33.54″. I definitely continue to believe that at times 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 the Lakewood precip values are estimated/adjusted from radar.

At 2400 obs Friday night the temperature from the VP2 was 64.7° RH 92% BP 29.88″R DP 62.3°
Cloudy, cooler, damp at 2400 Friday

Good morning from the cloudy, cool, foggy (see today’s featured image) home of the Walrus on Saturday.
