Brief Veteran’s Day warmup then (late Tuesday) sharply colder with brief AM frontal showers then later snow flurries update for Monday, November 11 and Tuesday, November 12, 2019 from West Rockville Maryland

Another one of those brief hiatus sessions from me over the past two days, so as usual I am combining details from both days into this one slightly condensed post.

Monday

Veteran’s Day Monday warmed up under partly cloudy skies while remaining dry. High temperatures on Monday were in the mid 60s in the early afternoon after early AM lows  in the upper 30s. Diew point temperatures climbed from the mid 30s in the early AM to the upper mid 40s by later in the morning. 

The maximum temperature was 66.0 degrees at 1328.

The minimum temperature was 38.0 degrees at 0622.

The dew point temperatures ranged from a low of 36 degrees @ 0215 up to a high of 47 degrees @ 1055.

The relative humidity values ranged from a high of 91% @ 0630 down to a low of 43% @ 1246.

The barometric pressure ranged from a high of 30.12 inches @ 0745 down to a low of 29.82 inches @ 2320.

The highest daily peak wind gust recorded across the street on the roof of the new USG building was 22 MPH that was recorded at 2257 from the SW.

There was no precipitation on Monday. 

Tuesday

Tuesday started out mild, cloudy, and damp with early AM light rain (0.13 inches) associated with a strong frontal system that blew through during the day. Colder conditions overspread the area by later in the day, under blustery, partly cloudy skies with occasional snow flurries (Trace). High temperatures on Tuesday were reached in the very early AM (upper 50s) then dropped quickly through the 40s and into the 30s in the afternoon (PM Max temp was 39.5 degrees at 1435.)  Temps continued to fall the rest of the day, reaching the low for the day right around midnight in the upper 20s. Dew point temperatures were in the upper 40s in the early AM during the light rain showers, then dropped all day thereafter to the mid teens by around midnight.  

The maximum temperature was 59.2 degrees at 0006.

The minimum temperature was 28.1 degrees at 2355.

The dew point temperatures ranged from a high of 49 degrees @ 0507 down to a low of 14 degrees @ 2355.

The relative humidity values ranged from a high of 91% @ 0507 down to a low of 54% @ 1219.

The barometric pressure ranged from a low of 29.75 inches @ 0116 up to a high of 30.30 inches @ 2354.

The highest daily peak wind gust recorded across the street on the roof of the new USG building was 28 MPH that was recorded at 1445 from the NW. Please remember that this anemometer is at a non-standard height of 60 feet above ground level (AGL), which can cause greater wind speeds than at the standard 33 feet AGL.

There was 0.13 inches of precipitation on Tuesday, including a trace of snow. My November monthly total precipitation is now 0.25 inches. My monthly snowfall is a trace.The year-to-date precipitation total is 44.82 inches.

My current downstairs station data is now 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, available in real-time 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 and can be found on the web at 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 on most days (when I have had rain that is) so should not be used except for general precipitation timing.

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.

The short Veteran’s Day two day holiday period was active at times. A really rousing Monday Night Football game was a highlight, probably the best game of the season, won in thrilling fashion in overtime by the Seattle Seahawks over the previously undefeated SF 49ers 27-24. A culinary highlight was an all day crockpot beef roast with potatoes, carrots, onions, mushrooms, mushroom soup and broth. It really came out better than I thought it would, as the beef was fork tender and juicy, and the vegetables were done just right. Perfect for a cold day on Tuesday, with the aroma of the cooking beef filling my apartment all day. 

Wednesday should feature the core of the cold, with lows in the low 20s and highs in the mid 30s under sunny skies.

Thursday and Friday should moderate some with highs in the upper 40s – lower 50s and lows around 30 under partly cloudy skies.

Over the weekend a cooldown into the lower 40s for highs and mid-upper 20s for lows should prevail under sunny to partly cloudy skies.

The period from now through the weekend should remain dry.  

At Midnight Tuesday, clear skies with a temperature of 28.1 degrees, relative humidity 54%, pressure rising at 30.30 inches with a dew point temperature of 14 degrees. Winds averaged 5 MPH from the N.

Currently at 0508 EST Wednesday the temperature is 23.4 degrees under clear skies, relative humidity at 67%, barometric pressure rising at 30.39 inches, and the dew point temperature at 14 degrees. Winds are averaging 2 MPH over the past 10 minutes from the NNW. Peak wind gust since midnight has been 17 MPH from the N at 0105.

Good morning from the walrus on this chilly early Wednesday.
