Wednesday continued our obnoxious July heat wave, with partly sunny, very humid and hot conditions with late afternoon clouds and a thundershower (0.22 inches) around 1730 with high temps in the mid 90s and lows in the mid 70s. Dew points soared after the early AM min in the low 70s, rising into the upper 70s by mid-morning and staying that way till the rain-cooled storm hit in the late afternoon, dropping temps into the mid 70s and dew points into the low 70s.

The maximum temperature was 96.4 degrees at 1538.

The minimum temperature was 74.0 degrees at 1904.

The dew point temperatures ranged from a high of 78 degrees @ 0917 down to a low of 71 degrees @ 1212.

The relative humidity values ranged from a low of 46% @ 1444 up to a high of 94% @ 1943.

The barometric pressure ranged from a high of 30.03 inches @ 0000 down to a low of 29.85 inches @ 1632.

There was 0.22 inches of precipitation on Wednesday. There has been a total of 5.97 inches of rain so far in July. The year-to-date total is now 28.63 inches.

My current online data (except for rainfall/snowfall – 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.

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 picked at some of my newly obtained Shoppers Grocery order which came early Wednesday evening, crackers and cheese, a variety of salads after the order came in the evening, and a pre-order egg, cheese, and turkey burger on a toasted everything bagel for lunch. I tried to catch up on a few things, but I am still well behind. I chatted with Robin and Gideon on face time, and on the regular phone on her way to work with Tracy. 

We have a succession of hot, humid days ahead through the weekend, with a temporary one day slight break on Thursday with partly cloudy skies and late afternoon showers/storms from the remnants of Tropical Storm Barry. High temps should be in the low 90s, with lows in the mid 70s.

High temperatures otherwise (Friday through Sunday) should be in the upper 90s to around 100 with heat indicies well above 100, with low temps in the muggy, uncomfortable mid-upper 70s. Scattered thunderstorms (50 POP) may occur in the late afternoon or evening on Sunday and into Monday ahead of some cooler, much-wanted relief through most of the upcoming week, but dry very hot days should be expected through most of the 3 day weekend.

Midnight Wednesday recorded a temperature of 74.7 degrees, relative humidity 94%, pressure falling at 29.88 inches and the dew point temperature at 72.9 degrees under partly cloudy skies.

Currently at 0724 the temperature is 75.8 degrees under mostly sunny skies (just widely scattered high clouds – altostratus and cirrostratus), relative humidity at 96%, barometric pressure steady at 29.89 inches, and the dew point temperature an already uncomfortable 75 degrees. 

Good morning from the walrus on this mostly sunny Thursday (so far). Today’s attached (featured) image is
