A partly sunny, mild update for West Rockville Maryland on Sunday, January 21 2018

Sunday featured very mild, partly sunny skies as high temperatures once again rose into the mid-upper 50s. The Sunday maximum temperature from the VP2 (57.5°) was recorded at 1508 while the minimum temperature (34.3°) was recorded at 0607. It was my first daily minimum temperature above freezing in 2018. My dew point temperatures continued their slow climb upwards, ranging from 30° at 0135 up to 43° at 1605. Relative humidity values rose from yesterday’s values (85% – 56%). Barometric values rose today from a low of 30.12″ at 0000 up to a max of 30.24″ at 1100.

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 talked with Ray a few times about concerns over his weather equipment, and also this You Tube video on flood reporting on a half hour old 1937 movie clip on the History of the U.S. Weather Bureau.  I finished up my December weather summary and data spreadsheet and emailed it off to the North Jersey Weather Observers (NJWO) for publication in their WEATHERSHELTER monthly newsletter. 

We have warm 50°+ temps now under mostly cloudy skies (choatic sky of a few different types – see today’s featured image captured at 0945 Monday morning) with dim sum breaking through currently. Streets are a bit wet indicating the forecasted sprinkles have been falling this morning. Clouds should thicken and lower later on with light rain starting to fall by evening. High temperatures should get into the low 60s, with lows of only about 50°. AM showers and thundershowers (90 POP) on Tuesday with high temps in the upper 50s, falling off to around the freezing mark by late evening. Wednesday and Thursday should cool off to seasonable low-mid 40s for highs, mid 20s for lows under mostly cloudy skies. Friday looks to warm up a bit, with highs around 50° and lows around 30° under sunny skies.

On the Channel 4 weather website at 0959 radar is showing the scattered light showers in the immediate region, with greater areas of showers in much of PA and WV, with a serious line of showers and storms running north/south through MI, IN, KY and TN and points north and south to a lesser degree.

As of 0959, 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 mild with sprinkles around but not falling here presently.
