  • There was 0.54 in in my rain gauge this morning after a night of rain and freezing rain.  Thankfully, there wasn’t much ice accumulation and the issue now is fog.  The rain is expected to end this morning, then b […]

  • Thursday was a partly cloudy, milder day with clouds slowly on the increase in the PM, ahead of our rainy weekend. High temps almost reached the 50° mark after our first above freezing min since 12/4 (32.6°). Of c […]

    The final 2018 data tables were updated on 5/22/2019 for Maryland’s all-time record precipitation year. With the release of the “Maryland and Delaware Climatological Data Annual Summary” by the National […]

    • Great update Jeff. Listing looks quite comprehensive and complete. At least after this weekend’s rains even my station should go over the 60″ mark. As of this moment, my year-to-date total is 59.25″. I badly lag behind other stations for the year with this total. I don’t know what is the cause of this for sure, but there definitely are a variety of storms with different patterns that contribute to my lagging behind. I have been talking with Stanley Rossen over the phone most early mornings the past few weeks after he lost internet access, and we trade data. His annual precip total is quite close to mine, and he hasn’t gone over the 60″ mark yet either. With lack of internet access, he is not reporting into cocorahs. Many ways around this problem if he would only listen to Marty, Ray and myself and just change his phone situation right now- too wacky to explain here. Maybe we can talk over the phone over the holidays at some point I can try to explain just one of his crazy scenarios. Thanks again Jeff for keeping everyone up to date with the Maryland precipitation data records. One last thing, I did notice that the infamous Oakland COOP station made your list. It does appear that temps are a bigger problem than precipitation (not touching snowfall here however). CIAO!

      • Hey Kevin!
        I’ve noticed that certain deaths of the state have not been as pummeled as others but most have had far above normal totals. That you’re close to Stan’s annual total likely verifies that your readings are fine.
        Yes, it seems that the Oakland 1 SE ppt reporting isn’t as big of an issue as the temperature situation. They have exceeded their previous annual record. I wonder where the ppt gauge is located as opposed to the MMTS?

    • Jeff, Neither I nor Dave L could find the rain gauge.

      • Marty, that’s very strange that the rain gauge isn’t near the MMTS. I wonder where snowfall and depth are measured, and on what surface?

        • Maybe that means another field trip is in order. Marty is so busy, I know he wants to go up into the mtns and check out a few things. He may be too tired to go over this Oakland station problem any more – I think he would prefer to visit Dave Lesher more as of course would I. I checked the Maryland annual precip totals in cocorahs and right now Catonsville is over 82 inches, Thurmont over 81 inches, and Marty is in third place at 78+”. Ray Muller is further down the list at 71.03″- not sure if that amount is totally up to date or not. With Stan not reporting into cocorahs any more, his station will be falling by the wayside. I will talk to him – as county administrator I could add his precip data into his cocorahs record if he wants me to. He keeps encouraging me to post his Nov data to the masses – I have it all collected in a rather “busy” excel file. I might send it out to you and Marty and see what you think – if it could stand on its own. I don’t want to do much if any editing on the file. I collect his daily data most days over the phone and record it in this spreadsheet. His attention to detail may overwhelm all of us – but I don’t want to be the focal point/middle man on his data to answer questions about it. These days Stan can only be contacted through phone call or snail mail letters. No email!
          Thanks, Kevin

          • Thanks for the updates Kevin! I had a really busy weekend and couldn’t get to updates for the CoCoRaHS and Coop Data. Will attempt to do that today. When I checked this morning before leaving for work, there were only 3 Coop stations having reported data today so figured it was best to wait.

            Jeff

          • Kevin, I’ve updated the data tables with this morning’s reports.
