Sunday continued our nearly 2 week cold snap (last above 32 max was 34 on 12/26) but is starting to moderate with max temps today rising into the twenties with lessening winds, starting to come from a southerly component.

A sunny, very cold and windy update for West Rockville Maryland on Friday, January 5 2018

Friday cleared up the skies from yesterday’s storm, but the cold air came back in with the coldest ever max temps in my short history here at my current location. The meager snow cover had no real chance to melt even out in the sun, but the wind did redistribute the remaining snow around. I had my first max temp ever in the teens. The Friday minimum temperature from the VP2 (10.1°) was recorded at 0731 while the maximum temperature…

A cloudy, snowy early AM then colder, windy, clearing rest of the day with occasional snow flurries update for West Rockville Maryland on Thursday, January 4 2018

Thursday started out cold and dry for the first few hours then light snow (estimated at 0.5″, water equivalent of .03″) started and fell for a few hours, as the temperature fell through most of the 20s and with increasing winds from the big storm offshore, wind chill temps really plummeted. We were just brushed by the storm here, but over in Ocean City MD on the ocean, blizzard warnings were in effect and they got about a foot of…

What is a “bomb cyclone”?

What is a “bomb cyclone”?

This week the East Coast is experiencing a “bomb cyclone”. This bombogenesis process is fascinating and the term is thrown out to the public and not explained well enough for the general masses to understand it. Live Science just put out a great article on it,  at the following link:  https://www.livescience.com/61327-bombogenesis.html?utm_source=notification

A sunny, very cold update for West Rockville Maryland on Tuesday, January 2 2018

The second day of the new year was another cold one to give 2018 quite a start. Sunny, really brisk temps continued as temps just reached the low 20s for high temperatures. Despite the well below freezing temps the light snowcover has decreased to a trace due to sublimation as the snow evaporates directly into the air from the sun’s rays and low dew points. The Tuesday minimum temperature from the VP2 (10.5°) was recorded at 0711 while the maximum…
