A mostly sunny, still cold update for West Rockville Maryland on Saturday, February 3 2018

Saturday started out cold (Min of 13.7° was my coldest min since Jan 7 when I had a min of 5.9°) that took a while to warm up as expected, barely getting over the freezing mark in the afternoon. I was out running errands in it, and with little to no wind, I actually walked around (short distances and short time periods) with just a shirt on. I always bring a coat along in case there is a car breakdown and have to be outside in the elements for a much longer time period. It was a sunny day, with not a cloud in the sky most of the day. The Saturday maximum temperature from the VP2 (33.0°) was recorded at 1631 while the minimum temperature (13.7°) was recorded at 0637. Dew point temperatures remained low all day, ranging from a low of 6° at 0000 up to 14° almost 24 hours later at 2347. Relative humidity values lowered some today (79% – 38%). Barometric values rose a bit more today, staying high all day, ranging from a high of 30.55″ at 0842 down to a low of 30.34″ much later at 2352.

Remember now you can get the VP2 data on Weatherlink. You can access the data through http://www.weatherlink.com/user/walrusman444.

I am posting daily to weather underground. My ID is KMDROCKV200 and my station is called “Gardens of Traville.” Data is online, normally just about in real-time. I contribute daily to cocorahs as Rockville 2.8 WNW, Station ID MD-MG-115. Please remember that Weather Underground does not report snow data, and reflects what is recorded automatically through the tipping bucket VP2 gauge.

I got up in the late morning so I could prepare to run a few errands with Uber Mike’s help. Mike drove me up to the Hair Cuttery in downtown Damascus for a haircut from Sam, one of my daughter Tracy’s restaurant/bar friends.

Later I got a brief phone call from Ray who needed some relative humidity calculations done quickly to help out our mutual weather friend Bobby Miller. I worked some more on organizing my 2017 spreadsheet data, and getting some backlogged April data caught up so I can finish out the year and produce an annual summary. 

We were cold and clear overnight, merging into a sunny and cold day, with temps in the teens overnight then rising slowly through the 20s and low 30s during daylight hours. Clouds on the increase late, with the temperature only dropping off a few degrees all evening and through the overnight period into early Sunday. There is a Winter Weather Advisory for my area scheduled to go into effect on 10 AM and last till 4 PM for a mixed bag of snow/sleet/freezing rain falling (100 POP). It should change to all rain by late afternoon as temps warm up a bit. Highs will be in the upper 30s with lows in the low-mid 20s. Monday should be sunny with highs in the mid 30s and lows in the low 20s. Tuesday should be partly cloudy with high temps in the low-mid 40s and lows around the freezing mark. Wednesday looks cloudy and rainy (100 POP) with high temps in the upper 40s and lows in the mid 20s. Mostly sunny skies should return on Thursday and colder, with highs in the mid 30s and lows in the low 20s.

On the Channel 4 weather website at 0813 radar is showing snow falling over much of PA, WV, and western MD. Much of this “snow” is probably aloft as the surface conditions are still quite dry. Gradually the atmospheric column will fill and we should start getting the “mixed” bag by mid-late morning.

As of 0813, the data from the VP2 (coming from the ground radiation shield about 4 feet off the ground just under and out from the balcony) and the Lakewood WXBug station are as follows:

Cloudy skies and milder this morning.
