October started out much warmer, moderately humid, partly cloudy and dry on Tuesday. Low temps in the mid 60s in the early AM rose up to the mid 80s by mid-afternoon , lowering only down into the mid 70s by midnight. Dew point temperatures started out in the low 60s in the early AM, rising up to around 70 by mid-afternoon. 

The maximum temperature was 85.8 degrees at 1548.

The minimum temperature was 65.1 degrees at 0645.

The dew point temperatures ranged from a low of 61 degrees @ 0047 up to a high of 70 degrees @ 1434.

The relative humidity values ranged from a high of 86% @ 0145 down to a low of 58% @ 1535.

The barometric pressure ranged from a high of 30.19 inches @ 0001 down to a low of 29.96 inches @ 2358.

There was no precipitation on Tuesday so the October monthly total is 0.00 inches.  The final September monthly total was 0.59 inches. The year-to-date total is 38.25 inches. Despite the rain on Monday we are still officially “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:

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. After lunch today (more details on that below) I saw this new station for myself from pretty close proximity. Pretty impressive but due to its 60 foot (approx) height off the ground temperatures and even rainfall will not be that accurate according to NWS specifications. Today’s featured image shows the roof of the building and if you look closely the new VP station, looking east from my kitchen window. 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 wasn’t able to do this very much in September unfortunately since precious little rain (only on three measurable days the entire month) has fallen from the sky.

Tuesday started out with some cereal, banana and milk before crashing. I laid low most of the day, had two grilled cheeseburgers, southern Potato Salad and Orzo salad for a late dinner. The Nats beat the Brewers late in the game, coming from behind to win 4-3 to advance to the NLDS final against the Dodgers on Thursday (evening I presume). On Wednesday night the Rays and A’s play in the AL wild card game. 

Wednesday will be hot and may have record setting heat at DCA with highs in the low-mid 90s and partly sunny skies with lows around 70.

Thursday should be partly cloudy and cooler with highs in the upper 70s and lows in the low 60s.

A cooldown to more like fall starts on Friday with highs around 70 and lows in the low-mid 40s under mostly sunny skies that should continue into Saturday with mid 60s for highs and lows in the mid 50s.

Sunday should be mostly cloudy with highs around 70 and lows in the mid 50s, then cloudy with showers possible on Monday and remaining cool.

On Midnight Tuesday, clear skies with a temperature of 74.5 degrees, relative humidity 80%, pressure falling at 29.96 inches with the dew point temperature at 67 degrees.

Currently at 0845 Wednesday morning the temperature is 71.9 degrees under mostly sunny skies, relative humidity at 94%, barometric pressure falling at 29.95 inches, and the dew point temperature at 70 degrees.

Good morning from the walrus on this mostly sunny, warm Wednesday. Today’s featured image shows the new USG building across the street to my east out my kitchen window and their new VP2 station in place just off the roof on the left at about 0800 Wednesday morning.
