Monday was a bit warmer of a day, with dew point temperatures starting to creep up. But it was still quite sunny and virtually cloudless. Overnight into Tuesday skies have remained sunny/clear with lows at sunrise warmer. in the mid 60s with dew points in the low 60s. The Monday maximum temperature was 87.3° @ 1639, while the Monday minimum temperature was 59.0° @ 0615. The dew point temperatures stayed relatively low in the early part of the day but started climbing in the PM/evening hours, ranging from a low of 52° @ 1442 up to a high of 65° @ 2144. The barometric pressure was still high early today but started to fall later in the day – the highest value being 30.30″ @ 0003 down to a low of 30.10″ @ 2102. The relative humidity values were roughly the same as yesterday’s, ranging from a high of 92% at 0634 down to a low of 32% at 1442.

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.

I had a crazy day and didn’t get the chance to compile this report till Tuesday evening.  I finally emailed out my May data and summary to everyone after email delays/glitches caused dissemination to run late. I started compiling trivia questions as I will be giving them out on Thursday evening. A busy week, other activities are planned throughout the week.

Monday started to warm up under sunny skies, with highs in the mid-upper 80s and lows in the upper 50s. Tuesday 90° high temps returned (low 90s actually) under mostly sunny skies, with lows in the mid 60s. Wednesday should be partly cloudy and still warm, with highs around 90° with lows in the mid 60s. Thursday should be mostly sunny and “cooler”, with highs in the mid 80s and lows in the mid 60s, with the 60 POP for PM showers mentioned yesterday removed from the forecast. Friday the 13th should be partly to mostly cloudy with highs in the mid-upper 80s and lows in the mid 60s. Saturday looks to be quite warm and mostly sunny, with highs in the seasonable upper 80s and lows in the upper 60s.

At 2109, Channel 4 radar is showing showers and storms over central PA heading SSE towards Maryland at this time. No mention is being made of this activity in our local forecasts, but there seems to be some strengthening to the area, and moving pretty quickly towards Maryland, though an hour or two away assuming the current motion and strength holds. “Chris” is now a hurricane but remains well offshore and heading slowly to the NE out into the North Atlantic Ocean eventually.

At 2109, 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:

Clear skies, slowly cooling off but still quite warm and dry

Station Relative Location Temp RH    DP     BP    Wind High/Low temp on Monday
VP2            Ground         83.4° 52% 64° 29.92″S NA      87.3°/59.0°

The total precipitation in the cocorahs gauge was 0.00″ through midnight Monday. The VP2 tipping bucket also had 0.00″. 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. Marty will be visiting soon and make some necessary changes to the rain gauges that should help improve performance.

Monday’s precipitation was 0.00″
July precipitation total is 0.02″
Year-to-date precipitation total 22.29″

WX Bug Lakewood 4500 ft, 83° 45% 60° 29.97″R Calm G W 5
                            140° from station                      88°/56°
The Lakewood rain gauge recorded 0.00″ of rain on Monday. The precip records have been updated from earlier in the week but I don’t know where they got all the monthly rainfall they are now reporting – they are now carrying a July monthly total precip of 0.39″ with the 2018 year-to-date (YTD) amount now at 34.79″. I definitely continue to believe that at times the disparities 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 Monday night the temperature from the VP2 was 72.8° RH 71% BP 30.10″F DP 62.8°
Clear, not as cool, dry at 2400 Monday

Good evening from the sunny, warmer and dry home of the Walrus late on this Tuesday.
