Ian Posted July 26, 2012 Author Share Posted July 26, 2012 Slight risk posted for tomorrow. ...OH/TN VALLEYS TO THE LOWER MID-ATLANTIC... RELATIVELY NEBULOUS SURFACE PATTERN IS ANTICIPATED IN THE WAKE OF WIDESPREAD TSTM DEVELOPMENT ON D1. ALTHOUGH THE INSTABILITY FIELD WILL LIKELY BE FRACTURED...A BROAD CYCLONIC FLOW REGIME WILL PERSIST BENEATH THE RIGHT ENTRANCE REGION OF AN UPPER-LEVEL JET CENTERED FROM THE LOWER GREAT LAKES TO NEW ENGLAND. THIS BREEDS POTENTIAL FOR ORGANIZED CLUSTERS GIVEN THE PRESENCE OF 25-45 KT WLYS AT 500 MB. THE MOST PROBABLE AREA FOR TSTM INITIATION ON FRI AFTERNOON APPEARS TO BE ALONG AND AHEAD OF THE COLD FRONT IN THE MIDWEST/LOWER OH VALLEY. LARGE-SCALE ASCENT SHOULD BE GREATEST IN THE FRONTAL ZONE WITH THE SHORT WAVE IMPULSE CENTERED ACROSS LOWER MI AND AN UPSTREAM IMPULSE APPROACHING FROM THE UPPER MIDWEST. HOWEVER...GUIDANCE DIFFERS SUBSTANTIALLY WITH THE DEGREE OF INSTABILITY IN THE REGION WHICH MAY BE RELATED TO OVERTURNING ON D1. SUSPECT WITH STRONG HEATING...NAM-RELATED GUIDANCE MAY PROVE CLOSER TO REALITY. WITH STEEPENING LAPSE RATES AND MODERATE EFFECTIVE SHEAR...PRIMARY THREATS SHOULD BE BOTH SEVERE WIND/HAIL. FARTHER E...ANOTHER FOCUSED AREA OF TSTM DEVELOPMENT SHOULD BE ALONG THE LEE TROUGH IN PARTS OF THE PIEDMONT/COASTAL PLAIN IN THE LOWER MID-ATLANTIC. ALTHOUGH HIGHER-LEVEL LAPSE RATES MAY BE POOR...STRONG HEATING AHEAD OF THE TROUGH AND MODERATE DEEP-LAYER SPEED SHEAR SHOULD SUPPORT A FEW ORGANIZED CLUSTERS PRODUCING PRIMARILY DAMAGING WIND.

CranberryWX Posted July 26, 2012 Share Posted July 26, 2012 Just got home from a work trip and catching up...Watch out for most of WV until 10PM CRW AFD ...WITH 3000+ J/KG CAPE OBSERVED ACROSS REGION. ISOLD CONVECTION IS BEGINNING TO FIRE UP IN CENTRAL IN AT 17Z...OUT AHEAD OF THE COLD FRONT...AND WILL SEE AN INCREASE IN CONVECTION AS THE DAY/EVENING PROGRESSES AND THE FRONTAL BOUNDARY INTERACTS WITH THE UNSTABLE AIRMASS. COLD FRONT WILL BE VERY SLOW TO MOVE TOWARDS THE CWA...AND WILL BE SOMEWHERE IN THE VICINITY OF PERRY COUNTY AROUND 00Z....WITH 40+ KTS OF 0-6KM SHEAR...AND OVERALL UNIDIRECTIONAL FLOW...WHICH WILL SUPPORT A DAMAGING WIND THREAT PARTICULARLY ACROSS NORTHERN ZONES...

chris87 Posted July 26, 2012 Share Posted July 26, 2012 Since when is IAD the toasty one probably has to do with IAD getting out of the high clouds sooner than DCA/BWI.... Link to comment Share on other sites More sharing options...

When DCA has a S wind and BWI took a long time getting rid of the clouds Just goes to show where we would be at if the clouds hadn't stuck around this morning.. DCA would be at 100-101 by now. Interesting jump on my PWS this morning when I broke the clouds at 11:45A... that's why I was saying earlier I wish I had a Solar Radiation monitor to compare to.
