Monday was a partly sunny, milder day but still staying below freezing all day. The Monday maximum temperature from the VP2 (30.1°) was recorded at 1636 while the minimum temperature (15.0°) was recorded at 0657. My dew point temperatures started to rise later in the day, ranging from 7° at 0000 up to 26° at 2308. Relative humidity values rose significantly (89% – 63%). Barometric values lowered some (but still quite high) from a very early AM high of 30.67″ at 0000 down to 30.50″ at 1504.

Remember now you can get the VP2 data on Weatherlink. You can access the data through http://www.weatherlink.com/user/walrusman444.

I am posting daily to weather underground. My ID is KMDROCKV200 and my station is called “Gardens of Traville.” Data is online, normally just about in real-time. I contribute daily to cocorahs as Rockville 2.8 WNW, Station ID MD-MG-115. Please remember that Weather Underground does not report snow data, and reflects what is recorded automatically through the tipping bucket VP2 gauge.

I spoke extensively with Ray and Marty about our upcoming storm, plus Ray’s weather legacy project and his new weather station coming through Amazon on Tuesday. I revisited the NOAA Central Library Daily Weather Map digital collection and viewed the weather map for the day of Ray’s birth back in early April 1949. The collection goes back to 1871, with every daily map from then through 1968 available for online viewing for free on the library’s website: http://library.noaa.gov/Collections/Digital-Documents/US-Daily-Weather-Maps. Other more recent collections are available to the present day at other spots on the internet.

We have cloudy skies now on this Tuesday morning with temperatures milder than they have been, just under the freezing mark at the present time. Clouds (Partly cloudy at times) should predominate during most of Tuesday with highs around 40°, light snow (70 POP) should develop sometime in the late evening with lows in the low 20s, with 1-2 inches expected through early Wednesday morning. For the rest of Wednesday partly cloudy and colder again, with highs in the mid-upper 20s and lows in the upper teens, Thursday and Friday should start warming up again, with highs in the low-mid 40s and lows in the mid 20s, with sunny conditions on Thursday and Partly Cloudy skies on Friday. Warming up further with sunny skies over the weekend, highs in the 50s and lows in the 30s.

On the Channel 4 weather website at 0850 radar is showing light snow falling out to my west and southwest, oriented NE/SW through parts of PA, OH, KY, TN and points SW into TX at the present time. That snow will gradually work its way into our area later on Tuesday.

As of 0850, the data from the VP2 (coming from the ground radiation shield about 4 feet off the ground just under and out from the balcony) and the Lakewood WXBug station are as follows:

Cloudy and not as cold this morning.

Station Relative Location Temp RH DP    BP     Wind High/Low temp Monday
VP2            Ground         29.0  91  27 30.52R   NA     30.1/15.0

There was no precipitation in the cocorahs gauge on Monday. The VP2 tipping bucket rain gauge under my balcony also reported no precipitation on Monday through midnight.

January precipitation is 1.45″.
January snowfall is 0.5″.
Snow on ground 0
The seasonal snowfall total is 4.3″.

Year-to-date precipitation total is 1.45″

The Lakewood rain gauge recorded no precipitation on Monday. It is still reporting 1.29″ monthly and yearly January 2018 precipitation.

Temp from the VP2 at 2400 was 28.6 RH 89% BP 30.50F DP 25.9. Partly Cloudy and not as cold at 2400.

Good morning from the cloudy, not as cold, still dry Walrus not so early on this Tuesday morning.
