Sunny, cooler, very dry and very windy at times update for Monday, February 25, 2019 for West Rockville Maryland
Monday was sunny, cooler, very dry and very windy at times. Winds gusted to 40-50 MPH locally at nearby stations with wind equipment. Air was very dry and very clear most all day. Temps reached highs in the mid 40s, then fell off some thereafter, reaching the mid 30s by midnight observation. In the metro area numerous trees and structures were blown down with the high winds, and power was out in many locations, but managed to stay on at my location. The HIGH WIND WARNING that was in effect most of the day expired in the evening.
The maximum temperature was 45.3° at 1547.
The minimum temperature was 35.8° at 2358.
The dew point temperatures ranged from a high of 21° @ 0000 down to a low of 6° @ 1350.
The relative humidity values ranged from a high of 41% @ 0000 down to a low of 21% @ 1348.
The barometric pressure ranged from a low of 29.74″ @ 0003 up to a high of 30.34″ @ 2358.
Monday had no precipitation. My February monthly total is still 3.44″ with my year-to-date total at 7.02″ for 2019.
No snow/sleet fell on Monday. My February total snowfall is still 7.3″ with the seasonal total at 24.3″.
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. For example during our big snowstorm back in mid-January 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. This scenario also developed nicely last Thursday as the sun melted most if not all of the snow in the tipping bucket rain gauge. 0.86″ passed through the tipping bucket all day Thursday even though no precipitation fell from the sky.
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 as I did this past Wednesday.
Tuesday should be mostly sunny with highs in the upper 40s and lows in the mid 20s.
Wednesday and Thursday should be partly cloudy with high temps in the mid 40s, lows in the low-mid 30s.
Clouds with light snow expected to fall on Friday, with highs in the upper 30s and lows in the low 30s.
Saturday should be cloudy and milder with rain, highs in the low 50s but with the temp dropping late, lows in the upper 20s.
Sunday should be cloudy and colder with highs in the mid 30s and lows in the low 20s with snow and rain expected late, extending into Monday.
Midnight Monday night found the temperature at 35.8°, relative humidity 32%, pressure rising at 30.34″ and the dew point at 8.8° under a clear sky.
Currently at 0900 the temperature is 34.8° under partially cloudy, dry, contrail-laden skies (see today’s featured image) , relative humidity at 40%, barometric pressure rising at 30.46″, and the dew point at 13°.
Good morning from the sunny, windblown walrus on this dry Tuesday.
