Sunday was the beginning of September and with it the promise of cooler fall weather eventually. The day was partly sunny, dry, a bit cooler, still moderately humid with some light rain in the area in the afternoon but not at my station. High temperatures reached 80 by mid-afternoon after a not so cool early AM with mins in the mid 60s. Dew point temperatures ranged from around 60 in the very early AM up to about 70 by late afternoon and down a bit into the upper 60s by midnight observation time.

The maximum temperature was 80.0 degrees at 1445.

The minimum temperature was 67.4 degrees at 0703.

The dew point temperatures ranged from a low of 60 degrees @ 0124 up to a high of 70 degrees @ 1840.

The relative humidity values ranged from a high of 90% @ 0711 down to a low of 67% @ 1448.

The barometric pressure ranged from a high of 30.30 inches @ 1131 down to a low of 30.17 inches @ 2353. 

There was no precipitation on Sunday to start the month of September off dry. In case you missed it yesterday, the final total precipitation total for August was 7.63 inches, about twice the normal amount. The year-to-date total is 37.66 inches as we enter into September, above normal for this point in the year.

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 early this month (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.

I rested a good while once again in the middle of the long holiday weekend, finally arising 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. In the evening one college game was on, a high-scoring affair won by Oklahoma over Houston 49-31. I had a dinner of two beef angus cheeseburgers and a bag of micro-steamed green beans. I took a look at some tired baked potatoes in the pantry and thought I better boil them up and make either soup or mashed potatoes with them. There were so many of them I froze half of the boiled potatoes for later, then wound up making mashed potatoes with the other half, but also to be eaten at a later time, as it took quite a while to get the potatoes cooked down into the right consistency for whipping up mashed potatoes. I tasted them though, and they turned out well. I continued to follow the very strong Category 5 Hurricane Dorian as it blew through the Northern Bahamas, moving very slowly West, with continued overnight coverage on the Weather Channel and local news media outlets and of course the internet.

Labor Day Monday looks to have partly cloudy skies with highs in the mid 80s and chances for showers and thunderstorms, lows in the mid 60s.

Tuesday and Wednesday should stay sunny to partly cloudy, with temps warming up in the mid 80s to around 90 with lows in the mid-upper 60s.

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

Friday should have partly cloudy to cloudy skies, remaining relatively cool with highs in the low 70s and lows in the mid 50s. Saturday should be mostly sunny and warmer, with highs around 80 and lows in the upper 50s.  

Hurricane Dorian is still looming big-time, well to the south, remaining an incredible Category 5 storm, as it meandered slowly west through the Northern Bahamas. It has slowed down its forward speed even more, and is predicted to be gradually turning northward over the next day or so, and should stay just offshore of the Florida coast then possibly make landfall somewhere in the Carolinas later in the week. Still too far in the future to tell what, if any, affect the storm may 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.

On Midnight Sunday the temperature was 72.8 degrees, relative humidity 86%, pressure falling at 30.17 inches and the dew point temperature at 68 degrees under partly cloudy skies.

Currently at 0740 Monday morning the temperature is 70.8 degrees under partly cloudy skies (mostly broken to scattered stratocumulus and altocumulus with the sun breaking through occasionally), relative humidity at 94%, barometric pressure steady at 30.11 inches, and the dew point temperature at 69 degrees.

Good morning from the walrus on this partly cloudy Labor Day Monday
