Fourth of July Thursday was as hot as Wednesday, but even more humid, with mid-afternoon thunderstorms (0.63 inches) that turned a partly cloudy day in the AM into a mostly cloudy one during most of the PM, which affected the visibility of the local evening fireworks shows. We did manage to get over 90 in the early afternoon before the clouds and storms rolled in around 1400 , but then dropped through the 80s and held in the mid-upper 70s in the evening. Temperatures rose from the mid 70s in the early AM to the low 90s by early afternoon and then slid down into the lower mid 70s by observation time.  The dew point temperature started out in the lower 70s in the early AM but rose uncomfortably to the upper 70s by mid-day, and once again stayed above 70 the rest of the day.

The maximum temperature was 90.8 degrees at 1303.

The minimum temperature was 73.5 degrees at 2359.

The dew point temperatures ranged from a low of 71 degrees @ 0000 up to a high of 78 degrees @ 1206.

The relative humidity values ranged from a low of 60% @ 1340 up to a high of 95% @ 1925.

The barometric pressure ranged from a low of 29.96 inches @ 0046 up to a high of 30.10 inches @ 2305.

There was 0.63 inches of precipitation on Thursday. A total of 1.36 inches of rain has now been recorded in July. The year-to-date total is 24.02 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. 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.

On the Fourth of July Thursday I had shredded wheat, banana and skim milk. Later I had a bit of kimchee. Kind of a late supper after all the fireworks when I had foreman grilled turkey cheeseburgers with sliced onion and horseradish sauce/mustard on rye (no burger buns, grocery ran out of them). Later on I had a few chocolate chip cookies for dessert.  I watched some baseball after catching the Nathan’s Hot Dog Eating Contest on ESPN live from Coney Island NY. Joey Chestnut won for the 7th year in a row. Miki Sudo was the women’s champion for the 6th year in a row. 

This hot, humid partly cloudy pattern should continue through Saturday, with a good chance for  afternoon/evening thunderstorms that may be quite heavy at times. Temps should peak out in the upper 80s to the low 90s, with lows in the low 70s.

A slightly cooler trend should start on Sunday but still with storms possible that day, highs in the mid 80s and lows in the mid-upper 60s.

Continuing on Monday through Wednesday with slightly cooler temperatures but dry with no storms or rain expected, partly to mostly cloudy skies, highs once again in the low-mid 80s and lows in the mid-upper 60s.

Midnight Thursday recorded a temperature of a muggy 73.5°, relative humidity 95%, pressure falling at 30.09 inches and a dew point temperature of 72.1° under partly cloudy skies.

Currently at 1550 the temperature is 88.7° under partly sunny skies, relative humidity at 67%, barometric pressure falling at 30.06 inches, and the dew point temperature a most uncomfortable 76°.

Good afternoon from the walrus on this sunny, muggy Friday. Today’s featured (attached) image and the image below were taken on Wednesday. Because of problems loading these images into my image library here on weathertogether.net for yesterday’s post, I only could post them on facebook and email. I posted the post for Tuesday and Wednesday in my activity feed so please check there. Interesting to note the picture of the sun below, with the partial blue sphere with a white dot to the lower left of the sun image, most likely an effect of the phone camera interaction with the sun.  The actual featured image shows the usual view to the west past my rain gauge, but with a few contrails to note.
