Wednesday was mostly sunny, pleasantly cool, especially in the early AM with low 50s mins and still dry. High temperatures reached the low 70s once again, but later in the evening the dew points and temperatures started to creep out ahead of big changes on Thursday.

The minimum temperature was 51.9° at 0613.

The dew point temperatures ranged from a low of 42° @ 1244 up to a high of 52° @ 1957.

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, normally just about in real-time now 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 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.

Thursday should be partly cloudy and warmer, with chances of afternoon showers and possibly severe thunderstorms and highs in the mid-upper 80s, lows in the mid 60s.

Good morning from the walrus on this still pleasant Thursday. For today’s featured image, I took a picture out at my rain gauge looking west just prior to sunset around 1900 showing quite a bit of high clouds foretelling our cloudier Thursday forthcoming.
