Oh, month to date rainfall. Interesting. @wxmeddler might be a useful product to add to the page!

Would recommend a Tempest as a quick replacement. I've had one for several years and it's quite cost effective. If you get a backup power pack from them, your data will be preserved and uploaded post-event for documentation. It's a very nice backyard product.

Latest HRRR really tries to give the Mason-Dixon counties a solid few hours of soaking rain.

Great question! Long term data is stored, but the website hasn't evolved yet to display that information. As a temporary work around, I've been taking the URL for the Las Vegas ASOS (you can use any western region ob) that capture the 5-min observations (https://www.weather.gov/wrh/timeseries?site=KVGT), then switch out the airport code for the MD mesonet stations, which use the nomenclature of three digits then MD (EX: 001MD, 002MD, etc.) Once you swap out the site code, refresh the page then left click 'Advanced Options' and you can select a time from the 'Number of Hours to Retrieve'. Paging @wxmeddler in case I missed anything.

18z HRRR is insistent on //some// rain for everyone, but it really tries to run a few decent thunderstorms north of I-66 that drop localized 1" amounts.

April is just about in the books, so we turn our attention to May flowers and the prospects of thunderstorms. CPC says cool and wet may be in order first.

That would be perfect actually.

That event was the biggest tornado outbreak that I can remember. The only other event that even comes close in my mind was April 16-17, 2011. Both events even spun tornadoes up into our area.

Nov 2026 - March 2027.

M0.09" not even enough to run down the gutters.

If this were winter, Ji would be going nuclear.

M0.6" Lisbon mesonet site.

An impressively warm April.

18z NAM absolutely laughs at any rain chances this weekend.

We're so used to rug pulls that it's hard to get excited at any D4 threat, let alone a D10.

We need several long round of slow, soaking rain and unfortunately that just doesn't seem to be in the cards.

Shocker, 00z Euro moved precip maximums to PA. We get some, but nothing sustained it seems.

I'm impressed with this airmass. It's late April and I'm only at 50° as we approach noon.

Only M0.11" RSTM2 COOP site. Didn't even get under the cars wet. To further illustrate how dry things have been, the Thurmont mesonet site recorded almost 0.4" of rain today, but the four inch soil moisture probe hasn't budged.

More records fall today: BWI: 91 (breaks old record of 90 set in 2002 and 2012) HGR: 90 (breaks old record of 88 set in 2002) IAD: 92 (breaks old record of 91 set in 2002) MRB: 92 (breaks old record of 90 set in 1941, 1976, and 2002)

BWI breaks the record.

I have a feeling that station will be important for tracking bay breeze fronts.

We don't need a flood, just a steady and soaking rain that totals about 1.5" regionwide. You could parse it out about 0.1" - 0.2" per hour over several hours.
