Partly cloudy, warm, moderately humid but still dry update for Sunday September 29, 2019 from West Rockville Maryland
It was partly cloudy, warm, moderately humid but still dry on Sunday. Low temps around 70 in the early morning hours rose into the mid 80s by late afternoon. Dew point temperatures were in the upper 60s in the very early AM hours, but dropped slowly into the low 60s by mid-evening.
The maximum temperature was 84.1 degrees at 1620.
The minimum temperature was 70.4 degrees at 0555.
The dew point temperatures ranged from a high of 68 degrees @ 0000 down to a low of 62 degrees @ 2135.
The relative humidity values ranged from a high of 86% @ 0607 down to a low of 53% @ 1620.
The barometric pressure ranged from a low of 30.10 inches @ 0039 up to a high of 30.26 inches @ 2308.
There was no precipitation on Sunday so the monthly total is still 0.42 inches. The year-to-date total is 38.08 inches. We have officially been declared as “abnormally dry” right now and very close to the moderate drought line.
My current online data 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, 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
Unfortunately a recent development was found that is a discrepancy between my wxlink data and my VP2 display data. I noted this a week ago Friday when the low temperature came in as 50.2 degrees as I saw it in real time on my VP2 display, but on other sources tied in with wxlink I had a low of 52.8. Other variables also were a bit different. I don’t understand this discrepancy which I continue to notice in my records. I need to study close by VP2 stations in wunderground to see if I may be getting signal interference from another station all of a sudden. In a probably related development, I also continue to notice wind data for my station in wxlink (and therefore also in my weather underground data) a few days ago and has continued (And I have no working anemometer connected to my station). In a further development from Thursday afternoon, Marty was over helping me out and noticed on his way home VP2 station equipment at the top of the new University of Shady Grove building across the street. We looked for it online but couldn’t find it, but it possibly is still transmitting its data that my station is picking up but not being published online yet except to infiltrate my records. More updates to follow.
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. I haven’t been able to do this very much this month unfortunately since precious little rain (only on two measurable days all month) has fallen from the sky.
Sunday is NFL Sunday and I was up relatively early to see most of the 1300 game between my Giants and the local standing Washington Redskins. What turned out to be a battle between rookie QBs was won by the Giants easily 24-3. Also going on at the same time was the Browns surprising the Ravens in Baltimore 40-25. In the evening the Saints upset the Cowboys without scoring a TD 12-10. I made a good salad for dinner and cooked up some parmesan risotto to go along with it.
The snowstorm (up to 4 feet of snow in the highest elevations) raged out in the Northern Rockies most of the day.
Monday has been cloudy, cooler, and damp with morning light rain that surprised me as to its duration. I only had a high in the low 70s and lows in the mid 60s with the persistent overcast skies all day.
October will start on Tuesday with a brief hot spell with high temps in the 80s then low-mid 90s on Wednesday with lows in the upper 60s.
Thursday should be partly to mostly cloudy and not as warm, highs in the mid 80s and lows in the low 60s.
A cooldown to more like fall starts on Friday with highs in the upper 60s and lows in the mid 40s under sunny skies that should continue over the weekend.
On Midnight Sunday, mostly cloudy skies with a temperature of 71.5 degrees, relative humidity 75%, pressure falling at 30.25 inches with the dew point temperature at 63 degrees.
Currently at 2326 Monday evening the temperature is 66.7 degrees under cloudy skies, relative humidity at 91%, barometric pressure steady at 30.20 inches, and the dew point temperature at 64 degrees.
Good late evening from the walrus on this cloudy, damp Monday.
