Monday was a partly cloudy day overall, but in two distinct parts – mostly sunny, warm to hot through mid-afternoon, then turning cloudy (stratocumulus overcast) the rest of the afternoon into the evening and cooling off some, rain threatens to my south but nothing fell before midnight at my station. Temperatures rose from the mid 60s in the early AM to 90° by early-mid afternoon then cooling off to the upper 70s-low 80s the rest of the afternoon and mid 70s by late evening. Dew point temperatures started out in the upper 50s in the very early AM, rising through the 60s during the rest of the morning, then into the mid 70s by mid-afternoon and then down a bit into the low 70s by late evening. 

The maximum temperature was 90.0 degrees at 1436. This was the first 90° max for June and only the second 90° max for the year so far. 90.2° was reached on May 29. 

The minimum temperature was 64.3 degrees at 0537.

The dew point temperatures ranged from a low of 59 degrees @ 0001 up to a high of 74 degrees @ 1529.

The relative humidity values ranged from a high of 92% @ 0551 down to a low of 51% @ 1440.

The barometric pressure ranged from a high of 29.95 inches @ 0002 down to a low of 29.79 inches @ 2340.

There was no precipitation on Monday. There has been 2.12 inches of rain recorded so far in June. The year-to-date total is 22.41 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, 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 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 sleepy day, staying inside away from the heat of the day, and doing some telephone business at times, and computer work including finishing up my May data spreadsheet to get off to my final editor and creator Lowell Koontz by late evening for final processing. I only had clam chowder (with extra clams added) and a turkey bologna and cheese sandwich to eat all day, along with snacking on barbecue potato chips and a few crackers with kimchee. 

Tuesday should be partly cloudy and quite warm with highs near 90° and lows in the upper 60s.

Wednesday and Thursday should be sunny, hot and humid, with highs in the low 90s and lows in the low 70s

Friday through Sunday should be partly sunny, still quite hot and humid but mostly dry, with highs in the low-mid 90s with lows in the upper 60s to lower 70s. So it appears that June will finish out with a bit of a heat wave.

Midnight Monday recorded a temperature of 74.3°, relative humidity 90%, pressure falling at 29.79 inches and a dew point temperature of 71.2° under cloudy skies.

Currently at 0803 the temperature is 71.8° under partly sunny skies, relative humidity at 94%, barometric pressure rising at 29.86 inches, and an uncomfortable dew point temperature of 70°. Overnight around 0200 light showers with faint thunder came through from the west. 0.10″ accumulated in the VP2 tipping bucket rain gauge, an unofficial, quasi-accurate reading.Stay tuned for tomorrow’s report for the official accumulatioin. 

Good morning from the walrus on this Tuesday.
