Sunday featured more clouds and damp conditions, with late afternoon/early evening showers (0.08″) that were convective in nature, and in areas just 20 miles to my north, severe, with a radar indicated possible tornado just south of Frederick in the Urbana/New Market area. Ground truth confirmation has not come in yet.  If daylight shows damage, NWS may send out a survey team to assess the situation if it was a tornado or not. Other areas of the region also experienced severe weather with possible tornadic conditions. A line of showers/storms came through very early Monday AM, but as far as I could tell I only got more light rain out of it between 0100-0230.  High temps reached into the mid 70s by mid-afternoon, after early AM lows in the upper 50s. Light fog was noted in the early AM, but not dense like on Saturday morning. 

The maximum temperature was 73.8° at 1639.

The minimum temperature was 58.9° at 0450.

The dew point temperatures ranged from a low of 57° @ 0414 up to a muggy high of 67° @ 1335.

The relative humidity values ranged from a high of 96% @ 0804 down to a low of 76% @ 1636.

The barometric pressure ranged from a high of 30.01″ @ 0032 down to a low of 29.43″ @ 2355.

Sunday had 0.08″ of precipitation. April now has a total of 0.80″ of precipitation. The year-to-date total is 12.49″.

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.

Monday should be partly cloudy, cooler and windy at times, with highs in the upper 50s and lows around 40°.

Sunny on Tuesday with highs in the upper 60s and lows in the low 50s.

Wednesday and Thursday looks to be partly to mostly cloudy and warm, with highs in the mid 60s on Wednesday and low 70s on Thursday with lows in the mid 50s on Wednesday and low 60s on Thursday but as of now remaining dry.

Cloudy conditions with showers and thunderstorms look to return on Friday and Saturday with warm temps well up in the 70s with lows in the upper 50s to lower 60s. 

Midnight Sunday night found the temperature to be 72.9°, relative humidity 79%, pressure falling at 29.44″ and the dew point at 66.0° under cloudy, threatening skies.

Currently at 0430 the temperature is 59.8° under cloudy skies, relative humidity at 93%, barometric pressure steady at 29.42″, and the dew point at 58°.  It looks like about 0.12″ of rain fell since midnight. 

Good morning from the walrus on this cloudy, damp (but gradually drying out) Monday.
