Saturday warmed up some more with more sun than clouds than yesterday, but with evening thunderstorms threatening closeby (see today’s feature image of a severe thunderstorm cell to my NE around 2000-2030). Temperatures rose from the mid 60s in the early AM to the lower mid 80s by mid-afternoon with dew point values climbing through the 60s 

The maximum temperature was 83.4° at 1603.

The minimum temperature was 64.1° at 0516.

The dew point temperatures ranged from a low of 61° @ 0425 up to a high of 70° @ 1540.

The relative humidity values ranged from a high of 91% @ 0528 down to a low of 58% @ 1608.

The barometric pressure ranged from a low of 29.87″ @ 0248 up to a high of 30.03″ @ 2334.

There was no precipitation falling on Saturday. May has a total rainfall of 4.68″. The year-to-date total is 18.73″.

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.

Sunday should be partly cloudy, hot and humid with highs around 90° and lows in the upper 60s with late afternoon chances of showers and thundershowers.

Monday should have highs in the mid 80s with partly cloudy but dry skies, with lows reached late in the day in the low 50s after the front clears out.

Tuesday looks partly cloudy and cooler, with highs in the low 70s and lows in the upper 40s.

Wednesday looks to be partly sunny and a bit warmer, with highs in the mid 70s and lows in the mid 50s.

Thursday and Friday look to bring some heat back with highs in the mid-upper 80s and lows in the mid 60s.  

Midnight Friday recorded a temperature of 70.4°, relative humidity 81%, pressure rising at 30.03″ and a dew point temperature of 64° under partly cloudy skies.

Currently at 0728 the temperature is 66.1° under cloudy skies (stratocumulus), relative humidity at 91%, barometric pressure steady at 30.04″, and the dew point at 64°. Clouds should break up somewhat under initial daytime heating, but that heating will boil up the clouds later into possible severe thunderstorms in the late afternoon/early evening. 

Good morning from the walrus on this Sunday.

Below is a bonus picture of this evening’s thunderstorm cloud to my NE (best direction out from my balcony to view storms, though not a common direction for storm viewing in my area normally – even saw lightning flashes near the top of the cloud shown below – about 10 minutes later than the feature image was taken (2010-2020)) It was fun to track this storm via my personal observations, the Weather Channel, NOAA Weather Radio and my lightning detector during this time. It was near Mt Airy around 2000 but moved NE at 15 mph and by 2400 was probably near central Howard County.
