Sunday and Monday were cloudy, dreary days with a moist marine flow from a coastal LOW moving slowly up the Eastern Seaboard during the period with late Monday showers finally falling.  High temperatures held in the low 40s both days after early AM min temps just above the freezing mark in the mid 30s. Dew point temperatures rose from the low teens early Sunday into the 30s by afternoon and held there the rest of the day and on Monday.

The highest daily peak wind gust recorded across the street on the roof of the new USG building was 16 MPH that was recorded at 1630 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 0.05 inches of precipitation on Monday in light evening rain. My November monthly total precipitation is now 0.30 inches. My November monthly total snowfall is a trace. The year-to-date precipitation total is now 44.87 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.

Sunday was a big pro football day but I was only awake for the pregame shows. I caught up on my sleep after a bowl of cereal and sliced banana. I arose early Monday and tried to get caught up. I discovered a big problem with my September data in my master spreadsheet as half of the month’s worth of data had disappeared. I need to get that fixed pronto along with inputting my October data this week. I do have my cleaning engineer finally due to come on Wednesday afternoon. I got a new Davis console in the mail, and will be setting it up to replace the borrowed VP2 console I have been using to monitor the VP2 station across the street, particularly with wind data. I caught the MNF game from Mexico City won by the Chiefs, 24-17, over the Chargers. I made spaghetti and meatballs for dinner long after a breakfast of some delicious hot oatmeal. 

Tuesday through Thursday should be partly cloudy with moderating temperatures, highs in the low 50s and lows in the low-mid 30s except mid 40s on Thursday.

Friday should remain mild (highs in the mid 50s) with lows in the mid 30s with rain at times. 

Saturday looks cooler ( highs in the low-mid 40s and lows in the low 30s) with more rain at times. 

At Midnight Monday, cloudy skies with fog with a temperature of 40.8 degrees, relative humidity 93%, pressure rising at 29.80 inches with a dew point temperature of 39 degrees.

Currently at 1312 EST Tuesday the temperature is 50.3 degrees under mostly sunny skies (scattered light cirrus and cirrostratus clouds), relative humidity at 73%, barometric pressure falling at 29.85 inches, and the dew point temperature at 42 degrees. Winds are averaging 7 MPH over the past 10 minutes from the WNW. Peak wind gust since midnight has been 14 MPH from the NW at 1140. Early this morning and during the overnight fog developed from the left over moisture and stable, mild temps such as shown in today’s featured image. 

Good early afternoon from the walrus on this mostly sunny Tuesday.
