jewell2188 Posted April 15 Share Posted April 15 Glad the watch verified. It was always run of the mill “showers and storms” here today. We fail at snow and generally fail at severe. Wind and dry is always guaranteed lol. Link to comment Share on other sites More sharing options...
Kmlwx Posted April 21 Author Share Posted April 21 Some major damage over the weekend in parts of the area it seems. Saw big branches and debris along I-70 from PA into Maryland. Looks like things will be relatively quiet - maybe a window for some strong storms next Tue or so. Link to comment Share on other sites More sharing options...
high risk Posted April 25 Share Posted April 25 If the NAM Nest and HiResW ARW2 are correct, there would be a MRGL and eventually perhaps a SLGT for Saturday along and east of I-95, but they seem to be outliers with their slower timing and higher dew points (driving good instability with modest deep layer shear). Since slow timing and overmoistening are clear biases of both systems, it's unfortunately tough to buy their solution. At this point, I just hope to cash in on some heavier showers Friday evening and overnight. Link to comment Share on other sites More sharing options...

At this point, I just hope to cash in on some heavier showers Friday evening and overnight. Other than the storms along the Mason/Dixon line last weekend, it's seemingly been a really, really, really quiet stretch for severe on the east coast. Looks like Tue is going to be focused well to our north and west and it peters out by Wednesday. I'm not sure I'm seeing any appreciable "big signal" to exit the boring period. I've been peaking at the long range stuff and CSU/CIPS/NCAR stuff and don't really see anything on the horizon. Similar to winter, it's possible a smaller event comes into focus once it gets to short range view...but for now we are snoozing! 1 Link to comment Share on other sites More sharing options...

The slightly slower solution ended up verifying, and we do have a MRGL along and east of I-95 for this afternoon. There is actually some good model agreement that a broken line of thunderstorms will form around 2pm very close to I-95 in Maryland and extend at least a bit south of DC on the Virginia side. Looks like there will be some instability, but deep layer shear looks slightly weaker than it did in earlier progs, so a MRGL seems to be the right call (but a few wind reports are certainly possible, especially further east). 4 Link to comment Share on other sites More sharing options...

yoda Posted 2 hours ago Share Posted 2 hours ago Hmmm Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 254 PM EDT Mon May 5 2025 .SYNOPSIS... A cold front will slowly progress eastward across the region through Tuesday, then pull offshore Tuesday night. High pressure will follow briefly for Wednesday. A potent cold front is expected to move southeast from the eastern Great Lakes to and across the Mid-Atlantic late in the week. High pressure will likely follow through the upcoming weekend. && .NEAR TERM /THROUGH TONIGHT/... Isolated severe t-storms will be possible over the next couple of hours with current scattered activity across the area. However, it appears the main severe wx potential over the next 12 hours will be tied to the line of convection forming near Raleigh NC. Shortwave-trough lifting from southwest VA into western VA and low-level convergence are expected to encourage more widespread convection early this evening. Latest HREF fields suggest a broken to solid line of thunderstorms forming from near Frederick MD south to Fredericksburg. Given cooling aloft and some rotation already seen on radar, a tornado and hail threat exist, especially given that shear profiles are expected to strengthen. The main window for severe wx potential looks to be between 21Z-02Z. Convection is expected to weaken or lift north into Pennsylvania after 02Z. 1 Link to comment Share on other sites More sharing options...
yoda Posted 46 minutes ago Share Posted 46 minutes ago Watch potentially coming soon Mesoscale Discussion 0701 NWS Storm Prediction Center Norman OK 0429 PM CDT Mon May 05 2025 Areas affected...Parts of the Mid-Atlantic Concerning...Severe potential...Watch possible Valid 052129Z - 052330Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorms moving north out of southeast Virginia will migrate into a buoyant air mass in place across the DelMarVa region. Re-intensification is expected and may result in an uptick in the severe hail/wind threat. Watch issuance is being considered to address this potential. DISCUSSION...A mix of semi-discrete thunderstorms and weakly organized linear segments continues to migrate north out of southeast VA. While a few stronger cores persist, much of the convection currently appears weak/disorganized based on GOES IR imagery and MRMS vertical ice/echo top data. However, these storms are moving into an environment characterized by better buoyancy (MLCAPE between 1000-2000 J/kg) that is in place across the DelMarVa region. Consequently, some uptick in intensity is anticipated within the next 1-2 hours. Deep-layer wind shear sampled by regional VWPs is fairly modest - around 20-25 knots of 0-6 km BWD. However, this should be sufficient for a few organized cells and linear segments capable of producing damaging winds and 1.0 to 1.5 inch hail. ..Moore/Smith.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

yoda Posted 21 minutes ago Share Posted 21 minutes ago Watch up until midnight URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 228 NWS Storm Prediction Center Norman OK 600 PM EDT Mon May 5 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of District Of Columbia Maryland Southern Pennsylvania Northern and Eastern Virginia Eastern Panhandle West Virginia Coastal Waters * Effective this Monday night from 600 PM until Midnight EDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Scattered large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...Scattered linear clusters of strong to severe thunderstorms will likely develop and move northward into the Watch area this evening. A few of the stronger cellular storms will pose a risk for large hail (1 to 1.5 inches in diameter). A transient supercell or two is possible in addition to a couple of line segments. Strong to severe gusts capable of wind damage will be the primary hazard with these storms, but a brief tornado is possible mainly early this evening with this activity. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 35 miles east northeast of Hagerstown MD to 25 miles southwest of Patuxent River MD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). Link to comment Share on other sites More sharing options...
