Monday was partly sunny, mostly sunny AM, increasing clouds PM with a flash flood watch posted for the area in the afternoon and evening. Evening thunderstorms (0.23″) fell from 2200-2300 but weren’t particularly severe, though my internet connection went out for a while. Temperatures rose from the low 70s in the early AM to the mid-upper 80s in the mid-late afternoon hours, then fell back into the mid 70s during the cloudy, stormy evening. Dew point temperatures started out in the upper mid 60s in the AM hours, rising into the muggy low 70s by mid afternoon and remaining there the rest of the day.

The maximum temperature was 87.8 degrees at 1403.

The minimum temperature was 70.5 degrees at 0559.

The dew point temperatures ranged from a low of 67 degrees @ 0447 up to a high of 73 degrees @ 1623.

The relative humidity values ranged from a low of 52% @ 1407 up to a high of 92% @ 2326.

The barometric pressure ranged from a low of 29.89 inches @ 0018 up to a high of 30.00 inches @ 2152.

There was 0.23 inches of precipitation on Monday. There has been 1.89 inches of rain recorded so far in June. The year-to-date total is 22.18 inches.

My current online data (except for rainfall/snowfall – use the cocorahs link shown below for that dataset) 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, normally just about in real-time now 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 on 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.

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.

Monday was a day of rest and reflection for me. I finished up the leftovers from Saturday’s DC-AMS meeting, including some delicious fruit. I had my usual phone call discussion with my sister Deryl out in Michigan after the weekly internet weather talk show out of WBNY in Buffalo from noon till about 1310. Good climate discussion with Dr Vermette on the Buffalo State Univ staff. 

Tuesday through Thursday should be partly to mostly cloudy, warm, humid with daily chances of showers and storms with highs in the low-mid 80s and lows in the upper 60s.

Friday and Saturday look mostly to partly sunny, not as warm, dry with lower dew points, with highs around 80° and lows in the low 60s.

Midnight Monday recorded a muggy temperature of 73.6°, relative humidity 93%, pressure falling at 29.98 inches and a dew point temperature of 71° under cloudy skies.

Currently at 0710 the temperature is 70.7° under mostly cloudy (broken altostratus overcast) skies, relative humidity at 95%, barometric pressure steady at 29.94 inches, and a dew point of 69°.

Good morning from the walrus early on this Tuesday.
