A cloudy ,rainy, warmer update for West Rockville Maryland on Sunday, February 11 2018

Sunday featured more clouds and steady light rain, mostly in the morning with considerable early morning fog, then warmer temps well into the 60s in the afternoon. Dew point temps and air temps were one in the same for a good part of the day. More convective type clouds in the afternoon sky were evident. Temperatures rose up to the mid 60s by early afternoon into the early evenng, after a mild night well above the freezing mark in the mid 40s in the very early AM. The Sunday maximum temperature from the VP2 (66.5°) was recorded at 1659 while the minimum temperature (45.2°) was recorded very early at 0002. Dew point temperatures soared today, ranging from a low of 45° very early at 0000 up to a muggy 62° at 1409. Relative humidity values also rose again today (99% – 85%). They were at 99% for quite a while, with temps and dew points essentially the same (fine tuning revealed a couple of tenths differences in all cases – I have never gotten to 100% that I can remember). Barometric values lowered some more today, ranging from a high of 30.07″ at 0019 down to a min of 29.85″ later at 1354.

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 on the phone with my sister Deryl in Michigan, who just a few days ago had returned from her trip (with her husband Greg) down to Florida. She got back to the Wolverine State just in time for a snowstorm this past weekend. Greg was snowblowing the driveway as we spoke. I watched some Olympic action in the evening from windy Korea, some really cool shots of wind blown snow on the slopes which was so severe that they postponed all the downhill ski events for the day. They did have the cross country ski race and saw some snowboard action also amidst the pretty Korean snowy landscapes. 

We were cloudy and mild overnight Saturday into Sunday with steady light rain falling (0.71″) with more light-moderate fog during most of the early morning, visibilities below 1/2 mile at times. The temps rose through the 40s early into the muggy mid 60s by late afternoon. There were pockets of flooding in the region, mostly down to my south and east. We got 1.34″ of rain all weekend, which was lower than most, as we didn’t get any of the convective afternoon showers/storms other places received. On Monday there should be partly cloudy skies with AM clouds and PM sun and no chance for rain in the afternoon (I got 0.02″ of rain in light showers Monday morning, however) with highs in the mid 40s and lows in the low-mid 20s. Tuesday should be mostly sunny with no chance of rain , a bit colder with highs around 40° and lows in the low 30s. Mostly cloudy and warmer on Wednesday, highs in the mid 50s and lows in the mid-upper 40s with a 30 POP for PM showers. Thursday should be even warmer under mostly cloudy skies and a 60 POP for PM showers with highs in the mid 60s and lows in the low 50s. Friday should cool off a bit but still mild with highs in the mid 50s and lows in the mid 20s and a 70 POP for AM light rain as a frontal system passes through the region.

On the Channel 4 weather website at 1448 radar is still showing light to moderate rain showers scattered about in the persistent SW to NE flow but to my south and east over much of coastal VA, NC, lower eastern shore of MD, DE and NJ at the present time. My friend Marty sent me a copy of the 1200Z upper air sounding from Dulles airport (Balloon launch at the Sterling VA WFO nearby). The 850 mb temp was in the mid 60s, even though the surface temp was in the 50s. As somewhat of a byproduct of these noon conditions, today’s feature image shows somewhat of a chaotic sky with different types of clouds at different elevations going in different directions (tough to see the direction with a static shot – sorry it was though) 

As of 1448, 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:

Partly cloudy and cooler early this afternoon

Station Relative Location Temp RH DP    BP     Wind High/Low temp Sunday
VP2            Ground         46.5  47 27 30.46R    NA     66.5/45.2

There was 0.71″ of precipitation in the cocorahs gauge on Sunday through midnight obs. The VP2 tipping bucket rain gauge under my balcony recorded only 0.33″ (same as yesterday) of precipitation on Sunday through midnight. So far today since midnight through the current time it has recorded an additional 0.02″ of precipitation.

Sunday’s precipitation 0.71″
February precipitation is 3.17″
February snowfall 0.0″
Snow on ground 0.0″ (reported to the nearest half-inch)
The seasonal snowfall total is 5.2″.
Year-to-date precipitation total is 5.00″

WX Bug Lakewood 4500 ft, 45 45 24 30.45″R NW 9 G NNW 18 
                            140° from station                      67/45

The Lakewood rain gauge recorded 0.70″ of precipitation on Sunday. It is now reporting a 2.85″ monthly (February) total and 2018 year-to-date (YTD) amount of 5.10″ up considerably from yesterday’s report. So far today 0.02″ has been recorded here.

At 2400 obs Sunday night the temperature from the VP2 was 62.6 RH 93% BP 29.97″R DP 60.5. Cloudy and warm.

Good early afternoon from the partly cloudy, drying out and cooling off Walrus on this Monday.
