Labor Day Monday was partly cloudy, warmer and more humid than yesterday with a thunderstorm in the late afternoon (1700-1730 approx – heaviest at about 1710 – total for the day 0.39 inches). High temperatures reached into the mid 80s by mid-afternoon ahead of the storm, with lows for the day in the early AM and then again in the late evening at observation time. Dew point temperatures ranged from the upper 60s in the very early AM up to the low 70s by mid afternoon and down a bit into the upper 60s by midnight.

The maximum temperature was 83.9 degrees at 1541.

The minimum temperature was 70.4 degrees at 2359.

The dew point temperatures ranged from a low of 68 degrees @ 0000 up to a high of 73 degrees @ 1435.

The relative humidity values ranged from a high of 94% @ 1450 down to a low of 67% @ 1500.

The barometric pressure ranged from a high of 30.17 inches @ 0000 down to a low of 29.95 inches @ 1625.

There was 0.39 inches of precipitation on Monday to record September’s first measurable rainfall. In case you missed it the past few days, the final total precipitation total for August was 7.63 inches. The year-to-date total is now 38.05 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 on most days 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.

I rested a good while once again at the close of the long holiday weekend, as we start transitioning into what I hope will be a fine fall season of football and more pleasant, drier conditions. I finally arose in the afternoon to catch up on the latest with Hurricane Dorian, and have my usual late breakfast of cereal, banana, and milk but without the coffee. Dorian wasn’t moving much at all on Monday, essentially stalled over the Northern Bahamas.  In the evening one college game was on with Notre Dame beating Louisville 35-17. I also caught some baseball and RAW wrestling. I had the potatoes I made up yesterday, which were pretty good for doctored up mashed potatoes. I also had some cottage cheese while the potatoes were heating up.  I talked with Ray quite a bit about his new weather reporting procedures, and also with my sister Deryl out in Michigan in the afternoon and my daughter Robin in the evening. Later I caught more of the Weather Channel’s 24/7 coverage of Dorian, seeing the incredible damage the storm laid on the Bahamas, and then barely moving till very late, when it also “weakened” eventually to a Category 2, still quite dangerous. 

Tuesday has been sunny and pleasant, with lower dew points and really clear skies with temps in the afternoon now in the low 80s. Lows early this morning were in the mid 60s. Wednesday looks to be partly cloudy and hotter with highs in the low 90s and lows in the low 70s. 

At this point Thursday looks mostly cloudy and much cooler, with highs in the 70s and lows in the upper 60s with only slight chances of occasional showers.

Friday should have partly cloudy to cloudy skies, remaining relatively cool with highs in the mid 70s and lows in the upper 50s with thunderstorms possible as Dorian steams by our latitude well to the east out in the Atlantic Ocean.

Saturday should be mostly sunny and warmer, with highs in the low 80s and lows in the lower 60s.

Hurricane Dorian is still looming big-time, well to the south, weakening some down to a a Category 2 storm, as it has been gradually turning to the north finally away from the Bahamas and out in the South Atlantic Ocean. It is brushing ever so close to parts of the East Coast of Florida, then as it heads northward, will brush the GA and Carolinas coasts, possibly coming ashore a bit in North Carolina around Cape Hatteras before heading out to sea.  I still will be watching it closely in the days ahead to see where it tracks and how strong it gets.

On Midnight Monday the temperature was 70.4 degrees, relative humidity 94%, pressure rising at 30.03 inches and the dew point temperature at 69 degrees under partly cloudy skies.

Currently at 1429 Tuesday afternoon the temperature is 81.9 degrees under mostly sunny skies (a few scattered fair-weather cumulus are dotting the sky at the present time), relative humidity at 56%, barometric pressure falling at 30.05 inches, and the dew point temperature at 65 degrees.

Good afternoon  from the walrus on this mostly sunny Tuesday.
