Saturday was mostly cloudy, seasonably cold and dry.  High temperatures reached the upper mid 30s by mid-afternoon with early AM lows in the low 20s.

The maximum temperature was 37.0° at 1400.

The minimum temperature was 21.3° at 0552.

Dew point temperatures ranged from a low of 13° @ 1515 up to a high of 21° @ 2359.

Relative humidity values ranged from a high of 82% @ 0610 down to a low of 38% @ 1505.

Barometric pressure ranged from a high of 30.30″ @ 1040 down to a low of 30.20″ @ 1340.

Saturday had no precipitation. My January monthly total is 3.54″ and is also my year-to-date total for 2019.

My year-to-date snowfall is on hold unfortunately at 12.7″ with the seasonal total at 14.8″.

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 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 save for general precipitation timing. For example during our big snowstorm earlier this month the snow didn’t melt at all during the storm, and only started to record precipitation amounts a few days later when the sun and above freezing temperatures started to melt the snow.

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 also use a snow stake outside my balcony window to get an idea on how much snow has fallen (while it is snowing) and how much snow is on the ground.

Sunday should be cloudy but have warmer high temps in the mid 40s with lows in the 20s.

Monday should be partly cloudy and seasonable, with highs around 40° and lows in the 20s.

Tuesday clouds come in with the much anticipated strong cold front coming through, mild in the morning with low 40s for highs and rain, changing to snow in the afternoon with temps falling through the 30s and 20s to the mid teens by midnight observation. One to two inches of snow is anticipated to fall as of now. Clearing out in the evening.  

On Wednesday and Thursday, very cold temps/wind chills will be definitely in evidence. Wind chills may reach down to around the zero mark, air temps should only max out in the 20s with lows in the low-mid teens, perhaps dipping into the single digits in the coldest spots. Sunny skies will at least warm the heart at times when the wind slacks off like it will occasionally.

Friday should moderate some with highs around freezing, but lows still in the teens with partly sunny skies. 

Midnight Saturday night found the temperature at 30.0°, relative humidity 67%, pressure falling at 30.20″ and dew point at 20.5° under mostly clear skies.

Currently at 1327 the temperature has risen to 43.3° after an early morning low of 27.5° at 0727 under partly cloudy skies, relative humidity at 51%, barometric pressure fallng at 30.01″, and the dew point at 26°’.

Good afternoon from the Walrus on this mostly cloudy, milder Sunday.
