Wednesday was mostly sunny with a few scattered cumulus at times in the afternoon, hot and humid like it has been over the past several days. The Wednesday maximum temperature was 90.3° as it was yesterday but @ 1510, while the Wednesday minimum temperature was 73.1° @ 0600. The dew point temperatures held in the low-upper 70s all day once again, ranging from a low of 72° @ 0347 up to an uncomfortable high of 78° @ 0955. The barometric pressure lowered a bit from yesterday – the highest value being 30.25″ @ 0445 down to a low of 30.15″ @ 1857. The relative humidity was about the same as yesterday, ranging from a high of 97% @ 0729 down to a low of 57% at 1737.

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.

Wednesday was mostly sunny and hot, with highs around 90° and lows in the low 70s. Thursday should be much of the same as Wednesday temperature-wise under mostly sunny skies. On Friday a change to our hot pattern will hopefully start, with highs in the lower mid 80s and lows in the mid 60s with an 80 POP for thunderstorms under mostly cloudy skies. Right now on Saturday there is a 50 POP for AM showers under partly cloudy skies, but most notably a cooler high than we have had in quite a while, with highs in the upper 60s and lows in the low 60s. Sunday is expected to stay cloudy and even a tad cooler, with temps remaining in the mid 60s and an 80 POP for showers with moderate NE breezes.

At 0342, Channel 4 radar is showing no rain returns within the 4-state Mid-Atlantic region. The closest rain is in parts of the South (AL, MS, AR, TN) with the remnants of Tropical Storm Gordon, and more general showers further north in the Midwestern states of IL, WI, MI, IN and a few others.

At 0342, 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, warm and humid.

Station Relative Location Temp RH   DP     BP    Wind High/Low on Wednesday
VP2            Ground        76.1° 92% 74° 30.17″S NA      90.3°/73.1°

The total precipitation in the cocorahs gauge was 0.00″ through midnight Wednesday.
The VP2 tipping bucket has also recorded 0.00″ through Wednesday.

Wednesday’s precipitation was 0.00″
September precipitation total is 0.86″.
Year-to-date precipitation total 38.94″

WX Bug Lakewood 4500 ft, 76° 96% 75° 30.21″S WSW 2 G WSW 5
                            140° from station                  Wed Hi/Lo 93°/72°

The Lakewood rain gauge recorded 0.00″ of rain through midnight Wednesday. The September total precipitation total is currently still incorrectly showing 0.00″ with the 2018 year-to-date (YTD) amount still at 50.13″. 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 Wednesday night the temperature from the VP2 was 78.1° RH 88% BP 30.19″R DP 74.3°
Clear, warm, humid.

Good morning from the clear but warm and humid home of the Walrus early on this Thursday.
