The King of Prussia/Wayne area has missed everything significant for the whole thunderstorm season so far. Yup, you are the official rip zone of the week after Macungie gets hit in an hour....I got two storms yesterday, this one will pass just to my north by a few miles....so I can't complain too much.

Finally got ours. Just over an inch of rain so far. I am sure the grass will love it. Whats weird is that there is a good bit of lighting but little thunder for this event. The lighting has been mainly cloud to cloud. Maybe this event will pave the way for some storms tomorrow since the ground moisture has been increased.

NaoPos Posted June 24, 2011 Share Posted June 24, 2011 Watch up! no txt products yet.. http://www.spc.noaa....products/watch/ edit* txt product: The NWS Storm Prediction Center has issued a Severe Thunderstorm Watch for portions of Delaware eastern Maryland New Jersey eastern Pennsylvania coastal waters Effective this Friday afternoon and evening from 1245 PM until 800 PM EDT. Hail to 1.5 inches in diameter... thunderstorm wind gusts to 70 mph... and dangerous lightning are possible in these areas. The Severe Thunderstorm Watch area is approximately along and 50 statute miles east and west of a line from 40 miles northwest of Newark New Jersey to 35 miles south southwest of Dover Delaware. For a complete depiction of the watch see the associated watch outline update (wous64 kwns wou4). Remember... a Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. Discussion... tstms are expected to increase in coverage and intensity this afternoon ahead of cold front and along warm/stationary boundary where air mass has already become moderately unstable with MLCAPE of 1500-2000 j/kg. Area vwps show vertically veering wind profiles with 35-40 kt of deep-layer shear which will support organized multicell and supercell structures. While a brief tornado is possible with any storms that can favorably interact with warm front... large hail and damaging winds appear to be the primary hazards. Aviation... a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27025. ... Mead Link to comment Share on other sites More sharing options...

SmokeEater Posted June 24, 2011 Share Posted June 24, 2011 Discussion in the watch. DISCUSSION...TSTMS ARE EXPECTED TO INCREASE IN COVERAGE AND INTENSITY THIS AFTERNOON AHEAD OF COLD FRONT AND ALONG WARM/STATIONARY BOUNDARY WHERE AIR MASS HAS ALREADY BECOME MODERATELY UNSTABLE WITH MLCAPE OF 1500-2000 J/KG. AREA VWPS SHOW VERTICALLY VEERING WIND PROFILES WITH 35-40 KT OF DEEP-LAYER SHEAR WHICH WILL SUPPORT ORGANIZED MULTICELL AND SUPERCELL STRUCTURES. WHILE A BRIEF TORNADO IS POSSIBLE WITH ANY STORMS THAT CAN FAVORABLY INTERACT WITH WARM FRONT...LARGE HAIL AND DAMAGING WINDS APPEAR TO BE THE PRIMARY HAZARDS.

Thunder Road Posted June 24, 2011 Share Posted June 24, 2011 Just out of curiosity, what do we end up with when we have fairly decent low-level lapse rates (around 8) but really poor mid-level lapse rates (6 or less)? Also, 0-3km helicity is increasing along the warm front. If current SPC mesoanalysis is correct, it's already outdoing what the NAM progged last night.

dryslotted Posted June 24, 2011 Share Posted June 24, 2011 Oh and btw........... 1 year ago today I watched that cell plow through the city from 39 floors up. It was an unbelievable experience, it looked like the four horsemen were going to gallop out of the clouds. It had been very dry up until that day and the dust that was blowing off of all the buildings as the cell approached was just amazing to watch. I'm on the side that faces the direction of the stadiums, (pretty far away though) and I recall wondering how it went at the ballpark after it had blown through.

bluehens Posted June 24, 2011 Share Posted June 24, 2011 Going to be another day of disappointment here in New Castle county. Things keep pulsing up to my SW and then quickly dying off. Radar is horribly blank in general down towards Balt/DC....dew points are falling. What a waste of a week. Link to comment Share on other sites More sharing options...
ChescoWx Posted June 24, 2011 Share Posted June 24, 2011 Storm blew up just to my east...we had a brief shower with the storm just 2 miles to my east with .01" of rain. Rain since midnight 0.11" Temp fell from 80 to 72.3 with the shower. Hoping for some more rain to keep the lawn happy! Go Phils!! Link to comment Share on other sites More sharing options...
