Sunday featured hotter temps rising into the low 90s, quite humid during the mid-day hours but once again drying out some late in the evening after a surprise thunderstorm between about 2100-2200. High temps reached the low 90s by mid-afternoon after a slighly cooler overnight and with the storm then the rest of the evening. Temps fell to around the 70 mark by midnight observation time and it was a bit less muggy, drying out some after the storm. Dew points rose into the upper mid 70s by mid-day but dropped into the upper 60s near midnight observation time.

The maximum temperature was 92.2 degrees at 1542.

The minimum temperature was 70.8 degrees at 2335

The dew point temperatures ranged from a high of 78 degrees @ 1200 down to a low of 68 degrees @ 2110.

The relative humidity values ranged from a high of 95% @ 0755 down to a low of 55% @ 1540.

The barometric pressure ranged from a low of 29.93 inches @ 1830 up to a high of 30.03 inches @ 2130. (similiar values, different times than yesterday)

There was 0.80 inches of precipitation on Sunday so there now is a total of 4.79 inches of rain in August. The year-to-date total is now 34.38 inches.

My current online data (except for rainfall/snowfall so please use the cocorahs link shown below) is showing regularly on Weather Underground. My data is posted there every 5 minutes. My ID is KMDROCKV200 and my station is called Gardens of Traville. Data is online, available in real-time as it is being updated on a 5 minute interval. The web address for my data on weather underground is: https://www.wunderground.com/personal-weather-station/dashboard?ID=KMDROCKV200

I contribute my precipitation data daily to CoCoRaHS as Rockville 2.8 WNW, Station ID MD-MG-115 and can be found on the web at https://www.cocorahs.org

Please remember that my Weather Underground precipitation data reflects what is recorded automatically through the tipping bucket VP2 gauge, just as it does on WxLink 2.0. The tipping bucket has been producing erratic values every day of late so should not be used except for general precipitation timing. (for example, it recorded 2.15 inches of rain over a week ago (Sunday 8/4), with a 16.94 inch an hour rain rate at 0021 very early on that day that was way over what actually occurred.)

I actually use the data I post to CoCoRaHS from my 4 inch CoCoRaHS gauge I read manually as my official precipitation total each day.

Sunday started out busy before I crashed in the early evening. I had some cereal and a banana along with some iced coffee for a late breakfast. I watched more preseason football, baseball, and movies and listened to a lot more rock and roll on my computer and on the music choice selection on my comcast cable TV connection. I continued to prepare my July weather data and also the list of trivia questions which I will be giving out next Thursday to our apartment group. Lots to do!

Good late evening from the walrus on this stormy Sunday. We are on the edge of a severe thunderstorm warning issued by NWS Sterling, for SE Montgomery County and other parts of the region.
