Good lord part 2 - just got to my apartment in hunt valley - drove through a monsoon coming out of Balt city up 83 to 695 - got here and it literally hasn’t rained a drop 

Maybe .02” here. 

[dailylurker]

Probably close to an inch here in the swampy lowlands. The NAM 3k brings in more action around 8. HRRR not so much.

Haha! Beat you, looks like 0.04" eyeballing the gauge from window. Sheesh.

Edit, oh and that is from TWO different showers/thundershowers about 2-3 hours apart.

Wow nice hit!  That's more rain than I've had in seven weeks.

Not a drop and I don't expect any rain here for a very long time yet - maybe by mid-Oct

After only a 1.21” total for August this one day in early September was really needed.

Just got clipped again. Frederick has done well with this event so far.

Yeah it all stayed to the South of downtown. Went warned just after it passed me.

So many times Kyle Texas steals all of our rightful rain. They'd get 3 inches of torrential rain then I get home to Buda, 7 miles north and frackin' NADA. Everything is brown as a Thanksgiving turkey. I am getting sick as ebola of this damn drought.

You know whats the worst part?

No hope for hurricanes in the western gulf of mexico. Not with that brobdingnagian semipermanent trough in the East.

It's never gonna rain again in Buda. I am almost out of water. At the rate this is going, I am soon gonnabe forced to drink my damn piss just to survive like Bear Grylls in Africa.

I keep it chilly in my house.

This morning’s runs do not instill much confidence in the .5 - 1” my point and click suggests for tomorrow.

Aside from GFS, which ones? Other guidance looks solid.

6z nam 3km compared to 0z doesn’t give me much wiggle room here. Seeing areas east of here score yesterday has me feeling pessimistic too.

The euro looks great but I’m wondering if it will also show the heavier stuff east later.

.58” yesterday

NW winds here tomorrow morning according to my point and click; I'm not getting any rain with that.

The NAM Nest is glorious, but I have to acknowledge that I share the concern that others have about this event ending up more east of here.  There is a bit of an unfavorable trend in some of the guidance. 

[wxdude64]

Another morning with heavy dense fog. Currently 54.7/54.1.

Interesting that some guidance (Euro and NAM in particular) is developing precip overnight into early Sunday. Wonder if that can juice up.

What are you guys seeing with the new ASOS Vaisala 155E temperature and dewpoint sensors? They seem to read lower for max temperatures than the HO-1088, no? Also many more 100% humidity observations than previously? They rolled these out in most areas, but I haven't seen any sort of analysis to see how they compare to the older readings. When ASOS was rolled out, there was a lot of comparative analyses.

NAM’d again. Fingers crossed.

I've played with the HMP155's a lot. We had over 300 of them when I worked in North Dakota. I think they're the best Temp/RH combo instrument on the market right now, especially if you put them in an aspirated shield. They occasionally have a 1-3% low bias in RH at very high humidities (96-100%) but other than that they work fantastic as long as you keep them maintained and calibrated on the regular schedule. Vaisala recommends every year, but we did them every 2 years and it was no loss in quality. 95% of the ones we sent back for calibration after 2 years came back with only minor (<.2°C) (1-3%RH) adjustments.

Today is my kinda weather. Outstanding way to finish a workweek. And maybe storms tomorrow? I’m in.

[wxdude64]

Much warmer and more humid today. Currently 76.4/65.6 at 1:45 pm, 10 degrees warmer than yesterday at this time.

Partly cloudy with SW breezes 10-15 mph.

Finally getting around to some final tallies for my location over the course of Meteorological Summer.

Total Rainfall (JJA): 13.18"

Average High (JJA): 84.2F

Average Low (JJA): 68.5F

Average Temp (JJA): 75.0F

Most Rain Daily: 7/9 - 1.80"

Average temp of 75F puts this right near seasonal average, but a touch lower than normal (75.4-76F)

  Unfortunately, the 18Z joined the east trend.   We *may* still be in the game along the 95 corridor in Maryland, but we’re running out of wiggle room.   On the positive side, most guidance has a signal for some anafrontal rain, either during the late evening, overnight, or early Sunday hours.

29 years ago tonight and tomorrow, Hurricane Fran created a nightmare of destruction across Virginia.

 Winds to nearly 53 mph and nearly 8 inches of rainfall at my place.
