Saturday cooled down again as clouds held fast under light-moderate NE breezes with the stationary front lying just to our south, keeping us in the cooler sector. Occasional waves of light rain (0.29″) fell throughout the day, but heaviest in the evening. Temps started out the day in the mid 60s but fell slowly all day, finally reaching the mid 50s by late in the evening. 

The maximum temperature was 65.1° at 0001.

The minimum temperature was 55.1° at 2206.

The dew point temperatures ranged from a high of 64° @ 0000 down to a low of 57° @ 1038.

The relative humidity values ranged from a high of 96% @ 0057 down to a low of 68% @ 1238.

The barometric pressure ranged from a high of 30.09″ @ 1017 down to a low of 29.90″ @ 2349.

There was 0.29″ of precipitation falling on Saturday. May now has a total rainfall of 3.45″. The year-to-date total is now 17.50″.

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 at times 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.

Cloudy skies and even cooler temperatures with highs in the mid 50s and lows in the mid 40s are expected for Mother’s Day Sunday with frequent light rain showers all day and continued NE breezes.

Monday looks to continue this cloudy, wet, and cool pattern with high temps in the upper 50s and lows in the mid 40s.

Tuesday should be mostly cloudy but dry and remaining cool, with high temps in the upper 50s and lows in the low-mid 40s.

Wednesday and Thursday should be not as cool, with highs in the upper 60s to around 70° and lows in the low 50s under partly cloudy drying out skies.

Friday looks a bit warmer with highs in the low 70s and lows in the upper 50s under continued partly cloudy, dry skies.

Midnight Saturday found the temperature to be 55.6°, relative humidity 95%, pressure falling at 29.90″ and the dew point at 54.3° under cloudy, damp skies.

Currently at 0743 the temperature is 53.3° under cloudy, lightly rainy, breezy NE windy skies, relative humidity at 95%, barometric pressure steady at 29.81″, and the dew point at 52°.

Good early morning from the walrus on this continued damp Mother’s Day Sunday.
