WhiteoutMD Posted April 22, 2017 Share Posted April 22, 2017 What a storm today left work at 430 noticed as I was pulling on 270 a storm approaching from the west. About a mile on 270 moderate off an on rain then it stoped. I thought I was going to stay in front of it. Get on the beltway from 270 and noticed green leaves falling down all over the the road. A said that's odd. Look to the west and it looked like a wall of white blowing in. Then the rain started then the hail and then the hail got large and I said wow there goes the car. No cover hail and torrential rain lasting 5-10 min. Now I'm following the storm the biggest rainbow with the occasional hail stone falling with the rainbow. Approached college park and the hail and rain started again. I finally get home and notice my windshield has what looks like tiny stone chips all over it Then look over the car the left hand side of the car is now hail damaged. What's interesting is the hood looks ok and the roof and trunk just the piller that goes around the windows got it the worst. That was the craziest hail I have ever experienced. Inside the car was so load I was on the phone with my wife and she could not hear anything that I was saying and I couldn't hear her.

peribonca Posted April 22, 2017 Share Posted April 22, 2017 lots of damage at Colonial Beach VA (Northern Neck). Does anyone know if it was a tornado or straightline winds? We have a beach house there and heard from the neighbors all trees and powerlines are down. Link to comment Share on other sites More sharing options...

One came down on a car...driver suffered minor injures and his kid was okay. Car is a complete loss. Did a quick windshield survey and this is all straight line winds. Got at least 20 reports from this one cell alone...looks like tops wee ~50kft from the I-270/495 split to the PC line. Amazing HP supercell, but the SPC mesoanalysis nailed this with the wedge of instability nosing along eastern MoCo. Link to comment Share on other sites More sharing options...

BlizzardNole Posted April 22, 2017 Share Posted April 22, 2017 Looks like Sunday might be drier than expected in central/N MD. Would be nice as I have a lot to do in the yard. Oh if we could have had this in mid-winter along with the high over New England: More widespread rain will then push back northward for Sunday night through Monday night as low pressure system hits the east coast and slowly trudges northward. By Tuesday morning, the surface low center is still only progged to be near the Outer Banks of North Carolina. Link to comment Share on other sites More sharing options...
The Dude Posted April 22, 2017 Share Posted April 22, 2017 First storm since the derecho to actually reach severe status in my backyard. We had dime to nickel sized hail, and what may have been a small microburst that took out 4 healthy trees, including one big white pine that landed on my neighbor's house. It appears to have been caused by straight-line winds as all of the trees were blown down from winds out of the west. Impressively, one of the trees was snapped about 10-feet up, rather than at the base. I wasn't here at the time, but from talking to my wife and neighbors, and looking at the damage, I'm guessing we saw at least a 60 mph gust.

CAPE Posted April 22, 2017 Share Posted April 22, 2017 Just went out and mowed in the drizzle. Figured this might be my best shot to get it done. Raw with a stiff breeze, 54 currently.

dailylurker Posted April 22, 2017 Share Posted April 22, 2017 From the look of radar the rain is setting in for a while. Nice soaking rain is exactly what we need. The trees are looking beautiful. Good rain during leaf out makes them happy. Link to comment Share on other sites More sharing options...
CAPE Posted April 22, 2017 Share Posted April 22, 2017 WPC just updated their QPF. The northern edge of the heavier stuff is a bit further north, but the bulk of the best precip is still pretty far to the south over the next 5 days. Link to comment Share on other sites More sharing options...

A lack of any substantial rain, temps that zoom above normal almost every day, and above forecast everyday, and constant wind. All combine to make it a rough season. Thank God for Zyrtec. Anytime I'm outside for an extended length of time working in the yard I wear a good dust mask too; it's a huge help. Link to comment Share on other sites More sharing options...
Jebman Posted April 23, 2017 Share Posted April 23, 2017 Some of the AFD's concerning this storm are absolutely fascinating! Out of Blacksburg VA - http://forecast.weather.gov/product.php?site=RNK&issuedby=RNK&product=AFD&format=CI&version=1&glossary=1&highlight=off .NEAR TERM /THROUGH MONDAY/... As of 327 PM EDT Sunday... Flood Watch continues for most of the region through Monday evening. Positively titled upper level trough will deepen as it pivots to the southeast with a closed mid level low eventually traveling across the Southeast States. This pivoting will result in increasing difluent mid and upper level flow and associated divergence to the northeast of the low. A dual upper level jet structure may enhance upper level divergence over western North Carolina this evening into Monday morning. Rain, heavy at times will spread northeast across the region this evening into tonight and continue into Monday. Moderate to heavy rain is expected in the flood watch area, with 1.5 to 3 inches likely through Monday night. Locally higher amounts likely near the Blue Ridge, south of Roanoke. Initially the northern edge of the rain shield is sharp and utilized the 16z HRRR which captured the rain placement on the WSR-88d the best, then used a blend of GFS and NAM. The Day 1 excessive rainfall outlook placed an moderate risk across southwest portions of forecast area. This is supported by the better lift, jet dynamics, upper difluence and terrain enhancement. Models are hinting at higher qpf to our south across North Carolina and South Carolina. This may be suggesting potential for elevated convection to our south. Not expecting any thunderstorms or deeper convection for our area with wedge in place, and this should keep hourly rainfall rates limited. However, long duration rains will create a flood threat especially for creeks/streams and rivers. The flash flood threat will be isolated but cannot rule out some pockets across the southern Blue Ridge this evening into tonight. In contrast, for late tonight, there is some potential for dry slot to work toward the Mountain Empire before the easterly fetch off the Atlantic pulls rain back to the west Monday. Complex forecast tonight, but models agree in general weather of cloudy and rain. Low temperatures tonight will range from around 40 degrees in the mountains to near 50 degrees in the Piedmont. Increased pops on Monday in the west as vertically stacked cyclone slowly pinwheel southeast. Timing looked a tad slower on the movement. Good moisture transport continues Monday with PWAT around 1.25" along/east of the Blue Ridge and into the Piedmont. Stable thermodynamic profiles owing to residual wedge should hinder any thunderstorms. Northeast to north winds especially in the east will increase in speeds Monday afternoon into Monday night. This is a result of the strengthening pressure gradient between high pressure over the Northeast and low center over the Carolinas. Played high temperatures a little cooler with rich cloud cover and rain with readings from the mid 40s in the mountains to the mid 50-s in the Piedmont. I LOVE THIS WEATHER! I LOVE THIS STORM!

By far the worst for me yet this season, which is wierd considering the rain... Its been a terrible season for allergy sufferers. It started so early too, because of all the warm weather in late Feb and in March. Then summer arrived this month. I have had to scramble to keep up with our lawn and with yard work, and I have gotten a lungful of that damned pollen. I broke the Guinness record for sneezing this past week lol. This upcoming weekend (Apr 29-30) will make summer believers out of all of us whether we like hot weather or not, with 90 degree temps and dews easily in the upper 60s. Welcome to the first major Bermuda High of the summer --- oh wait! Its still only SPRING! geeze Link to comment Share on other sites More sharing options...
wxdude64 Posted April 23, 2017 Share Posted April 23, 2017 Thank goodness it isn't two months ago and 20 degrees cooler, that is one HECK of a wall just 10-15 miles to my south. Only had sprinkles all day and temps right at 50, nice actual spring weather. Link to comment Share on other sites More sharing options...

There would have been no 'weenie suicides' and WxWatcher 007 would have been plumb out of work! We would have gotten to enjoy 2 feet of fresh snow and I would have dug all of northern Virginia out of the snow all by myself with a Jebman Shovel. Can you imagine three days of snowfall with a slow moving pinwheeling vertically stacked classic winter storm with dual jet structure? I would have been beside myself with pure weenie joy!!!!!! Speaking of winter storm, you should see the KLWX AFD today! http://forecast.weather.gov/product.php?site=LWX&issuedby=LWX&product=AFD&format=CI&version=1&glossary=1&highlight=off This closed upper low will be moving at a snails pace over the next few days, and its associated surface features will do likewise. Overall, this is acting like a mid-winter storm, except that its too warm for any snow. Other than the lack of snow, the cool northeast wind, minor coastal flooding and long period of precipitation also reflect its rather winter-like nature. Another element of similarity will be the excruciatingly slow progress of the precipitation into our area. As the low pushes east tonight, the confluence over our region will only very slowly give way tonight and Monday, and the drier air in place, fed into the region by the elongated high pressure ridge (classic banana ridge often present on the northwest side of winter storms) will continue to feed dry air into it. Guidance has been slowing the advance of precip into the area through the day, with latest estimate having an arrival in the DC metro after midnight, and waiting until after dawn around Baltimore. This might be optimistically fast, given trends. However, certainly by mid-late day Monday, rain will have overspread the region. As the best forcing stays south, significant heavy rain is generally not expected across the region, so no flood watches have been issued, though if any were needed, it would be in central VA near the Blue Ridge where the upslope flow and upper level forcing is maximized. Lows tonight will be in the 40s with highs generally in the 50s on Monday. Link to comment Share on other sites More sharing options...
