Wednesday started out partly cloudy and briefly mild with temps reaching the above-freezing lower mid 30s by noon, then dropping all afternoon and evening through the 20s and 10s into the single digits by midnight, with below zero wind chills on brisk NW winds. Snow pack remained from yesterday’s light snow, keeping us refrigerated well most of the PM hours.

The maximum temperature was 33.0° at 1200.

The minimum temperature was 8.1° at 2354.

Dew point temperatures ranged from a high of 20° @ 1244 down to a low of -7° @ 2015.

Relative humidity values ranged from a high of 89% @ 0650 down to a low of 44% @ 1805.

Barometric pressure ranged from a low of 29.88″ @ 1211 up to a high of 30.35″ @ 2351.

Wednesday had no precipitation. My January monthly total is 3.58″ and is also my year-to-date total for 2019.

No snow fell on Wednesday. 2 inches of snow remains on the ground. My year-to-date snowfall is now 14.9″ with the seasonal total at 17.0″.

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.

Thursday, very cold temps/wind chills continue but slowly wane towards evening. High temps will be in the low-mid 20s, lows in the teens. Sunny skies will at least warm the heart at times when the wind starts to slack off as we approach evening.

Friday should moderate some with highs in the upper 20s, lows in the lower 20s with variably cloudy skies and possibly light snow showers or flurries at times, with less than an inch of snow expected.

Saturday and Sunday will moderate some more, with highs in the mid 40s on Saturday and low 50s on Sunday and lows in the 20s on Saturday and mid 30s on Sunday under partly cloudy skies.

Early in the week milder conditions continue, with 50s on Monday and reaching the 60s on Tuesday and Wednesday under partly cloudy skies. 

Midnight Wednesday night found the temperature at 8.1°, relative humidity 50%, pressure rising at 30.35″ and the dew point at -6.7° under clear skies.

Currently at 0721 the temperature is 6.4° under clear skies, relative humidity at 46%, barometric pressure rising at 30.50″, and the dew point at -11°.

Good morning from the Snowywalrus on this cold Thursday.
