Well once again I got really busy, mostly with compiling and disseminating my July weather summary and a shopping order plus a few grocery store visits that I have been remiss on posting my daily weather updates over the past several days. So as usual I will combine the past 5 days into one somewhat abbreviated but necessarily longer post today.

Friday was cloudy with some early light showers (0.03 inches – only rain during this 5 day period) and much cooler. In fact today’s high temp of 72.6 degrees was the coolest max since June 10 when I had a max of 71.1 degrees. What a refreshing change, and the start of a cool period of a lot of clouds with max temps holding in the 70s. With the clouds, though recording lower dew points in the 50s mostly, I still could not get the min temp below the 60 mark during the period. High temperatures only reached the lower 70s very early in the day, with the PM max only in the upper 60s. The mid 60s min for the day was reached just prior to midnight observation time. Dew point temps lowered from the low 70s in the very early AM then dropped slowly into the low 60s by evening. 

The maximum temperature was 72.6 degrees at 0146. (PM Max was 67.8 degrees at 1350.)

The minimum temperature was 65.0 degrees at 2354.

The dew point temperatures ranged from a high of 71 degrees @ 0000 down to a low of 62 degrees @ 1951.

The relative humidity values ranged from a high of 95% @ 0242 down to a low of 87% @ 1022.

The barometric pressure ranged from a low of 29.93 inches @ 0149 up to a high of 30.12 inches @ 2359.

There was 0.03 inches of precipitation on Friday so there now is a total of 7.32 inches of rain in August. The year-to-date total is now 37.35 inches, a recalculation based on exhaustive study of my earlier in the year records, made while compiling my July weather summary. This total may be revised slightly again after further study of my records for the year.

Saturday was partly cloudy and very pleasant, dry with further lowering dew point values. High temperatures reached the mid 70s by mid-afternoon, after very pleasant early AM low temps right above the 60 mark. Dew point temps lowered from the low 60s in the very early AM to the low 50s by early afternoon. and holding in the low-mid 50s the rest of the day.  

The maximum temperature was 76.3 degrees at 1637. 

The minimum temperature was 60.6 degrees at 0519.

The dew point temperatures ranged from a high of 63 degrees @ 0000 down to a low of 52 degrees @ 1350.

The relative humidity values ranged from a high of 92% @ 0000 down to a low of 46% @ 1333.

The barometric pressure ranged from a low of 30.10 inches @ 0202 up to a high of 30.23 inches @ 2303.

There was no precipitation on Saturday so there still is a total of 7.32 inches of rain in August. The year-to-date total still remains at the newly calculated (as of yesterday) 37.35 inches.

Sunday was partly to mostly cloudy, continued very pleasant and dry with dew point values remaining relatively low. High temperatures reached the mid 70s by late afternoon, after pleasant early AM low temps in the mid 60s. Dew point temps held in the 55-60 degree range all day, lower in the early AM. then rising to around 60 by mid-day and holding around that value the rest of the day.   

The maximum temperature was 75.3 degrees at 1752. 

The minimum temperature was 64.0 degrees at 0503.

The dew point temperatures ranged from a low of 55 degrees @ 0215 up to a high of 60 degrees @ 1158.

The relative humidity values ranged from a high of 83% @ 0659 down to a low of 50% @ 1626.

The barometric pressure ranged from a high of 30.25 inches @ 0943 down to a low of 30.16 inches @ 1923.

There was no precipitation on Sunday so there still is a total of 7.32 inches of rain in August. The year-to-date total still remains at the newly calculated (as of Friday) 37.35 inches.

Monday was partly cloudy, continued pleasant and dry with dew point values inching up a bit. High temperatures reached the mid 70s by early afternoon, after pleasant early AM low temps just below the 60 mark. Dew point temps rose a bit into the low 60s by afternoon after early AM values in the upper mid 50s.   

The maximum temperature was 74.2 degrees at 1352. 

The minimum temperature was 59.8 degrees at 0500.

The dew point temperatures ranged from a low of 57 degrees @ 0405 up to a high of 63 degrees @ 1404.

The relative humidity values ranged from a high of 91% @ 0456 down to a low of 63% @ 1232.

The barometric pressure ranged from a high of 30.21 inches @ 0700 down to a low of 30.10 inches @ 1942.

There was no precipitation on Monday so the August total rainfall remains at 7.32 inches. The year-to-date total is still 37.35 inches.

Tuesday was mostly cloudy, still reasonably pleasant and dry but with dew point values inching up some more. High temperatures reached the upper 70s by mid afternoon, after pleasant early AM low temps in the lower 60s. Dew point temps rose a bit through the 60s from very early morning till mid-day then falling off a bit into the mid 60s by midnight observation time. Moisture starting to creep in as a cold front from the Midwest heads in our direction for our Wednesday.   

The maximum temperature was 77.7 degrees at 1636. 

The minimum temperature was 63.4 degrees at 0620.

The dew point temperatures ranged from a low of 60 degrees @ 0000 up to a high of 68 degrees @ 1540.

The relative humidity values ranged from a high of 90% @ 0620 down to a low of 69% @ 1554.

The barometric pressure ranged from a high of 30.13 inches @ 0000 down to a low of 29.96 inches @ 1847.

There was no precipitation on Tuesday so the August total rainfall is 7.32 inches. The year-to-date total is 37.35 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.

This period was busy as usual. I tried to go shopping on Saturday but Uber wouldn’t process my card for some reason, even though they charged a little bit on it. I managed to go to the grocery store and picked up a few necessary supplies at Giant on Saturday and Safeway on Monday, then on Tuesday I got a grocery order delivery from Schwan’s which was able to process my card with no problems. I had some delicious vegetable alfredo lasagna for dinner on Tuesday night, after a few days of cereal, bananas and coffee for breakfast and jalapeno bologna sandwiches for lunch. I had the last of the angus beef burgers for dinner on another night with green beans. I watched a lot of baseball, and like I said earlier, I finished up my July data summary and statistics and disseminated it out to several dozen in the weather community and on this blog. I played trivia Thursday night and rummikub on Friday night, with 2 full tables of players. 

Wednesday has been cloudy and a bit warmer, but still managed to stay below 80 before showers moved in this afternoon and cooled us down to around the 70 mark. Clearing is coming in now in the early evening with cooler and drier air once again filtering in gradually over the next several hours. We should drop into the 60s for lows overnight once again.  

On Thursday we should clear out nicely with bright, sunny skies and highs around 80 and lows around the 60 mark.

Friday should once again be sunny with the warmest high temps of the week in the upper 80s and lows in the mid 60s.

Labor Day weekend (Saturday through Monday) should be mostly to partly sunny, with highs in the low-mid 80s and lows in the low-mid 60s and dry. 

Hurricane Dorian looms well to the south, and may start affecting the United States over the weekend into next week. Way too far in the future to tell what, if any, affect the storm will have on our area, but I will be watching it closely in the days ahead to see where it tracks and how strong it gets. 

Midnight Tuesday recorded a temperature of 69.4 degrees, relative humidity 86%, pressure falling at 29.98 inches and the dew point temperature at 65 degrees under cloudy skies.

Currently at 1827 Wednesday evening the temperature is a pleasant 70.7 degrees under partly cloudy skies with a contrails, scattered altocumulus and stratocumulus covering much of the sky with breaks, relative humidity at 83%, barometric pressure rising at 29.87 inches, and the dew point temperature dropping at 65 degrees.

Good evening from the walrus on this clearing out Wednesday. Today’s attached image is looking NE from my apartment balcony mid-Wednesday afternoon during our frontal showers.
