In the morning, there were reports of mixed rain and snow for the northern part of the region and possibly some stickage in northern Frederick and Caroll counties. Throughout the day, north winds and bands from PA brought graupel, sleet, and mixed rain and snow throughout a lot of the region. Then, after 3 PM, bands were forming that had less mixing in them and more snow. Then, at 4-5 PM, a band formed that mostly pure snow and brought heavy precip rates for a lot of the part of our region! Snow was reported as far into parts of Southern Maryland! Thundersnow/graupel was reported, which is really rare(0.07% chance in snowstorms), and especially cause it is in April! Stickage was reported in some parts of our northern region, and I was able to get a dusting/coating of snow, which is often recorded as 1"! Some people saw snow in temps as warm as 45-50+! It dropped from 44-42 in less than 5-10 minutes to 39 for me! Visibility dropped to <0.50 miles! That shows you the power of dynamic cooling and north winds! Bands were still forming in PA and coming SE to hit the DMV region as the sun starts to set and temps drop. There were also a lot of gusty winds. As the night continued, bands started to hit regions and some people woke up to a coating of snow on their cars and surfaces as temps drop. This was a pretty unique storm to say the least.
