Wednesday was mostly cloudy, a tad warmer and more humid as our pleasant weather changed into a bit of uncomfortable higher dew points that prompted me to put the A/C on again. We had mid-afternoon showers (0.31 inches approx from 1540-1640, heaviest around 1547) that accompanied a slow moving, weak frontal passage that was slow to clear and slow to dry us out in the post-frontal evening hours. High temperatures still stayed in the upper 70s in the early  afternoon, but temps fell to around 70 at the time of the showers and then fell a bit more into the mid 60s by late evening observation time. Dew point temps rose through the upper 60s in the AM into the low 70s by early afternoon ahead of and with the showers, but fell into the low 60s by observation time. 

The maximum temperature was 79.3 degrees at 1414.

The minimum temperature was 65.6 degrees at 2309.

The dew point temperatures ranged from a high of 72 degrees @ 1359 down to a low of 63 degrees @ 2258.

The relative humidity values ranged from a high of 95% @ 0637 down to a low of 73% @ 1518.

The barometric pressure ranged from a high of 29.98 inches @ 0000 down to a low of 29.84 inches @ 1505.

There was 0.31 inches of precipitation on Wednesday so the August total rainfall is now 7.63 inches. The year-to-date total is now 37.66 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 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 made some good progress on a few fronts (so to speak) on Wednesday. I got caught up with my daily wx and cocorahs reports through Tuesday, though I did not resolve that discrepancy in my year-to-date rainfall total yet. I had a brief mid-day appointment with a local social worker, over a friend visitation program I am interested in participating in. Unfortunately the program has a wait list, so I may not get a friendly volunteer visit for a month or two.  I had a great breakfast of cereal, banana and coffee thereafter, and then for dinner I baked haddock in the oven along with potatoes and a microsteamed broccoli and cauliflower that was all quite delicious, topped off by some more chocolate chip ice cream for dessert. I enjoyed watching an unusual day game from Seattle, where the Yankees were playing the home standing Mariners and won the game 7-3 behind 4 home runs and some stellar clutch pitching.  

On Thursday we should clear out nicely with bright, sunny skies and highs in the low 80s 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 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 Wednesday recorded a temperature of 66.9 degrees, relative humidity 94%, pressure rising slowly at 29.91 inches and the dew point temperature at 65 degrees under mostly clear skies.

Currently at 0450 early Thursday morning the temperature is a pleasant 62.4 degrees under clear skies, relative humidity at 91%, barometric pressure rising at 29.95 inches, and the dew point temperature dropping at 60 degrees.

Good morning from the walrus on this clear early Thursday. Today’s attached image is looking NE from my apartment balcony late Wednesday afternoon as skies were clearing after the earlier showers. Note if you can the lower level stratocumulus layer giving way to the scattered higher altocumulus layer. That is a mildly chaotic sky, albeit toned down from the usual turbulence associated to the usual chaotic sky.
