NORRISTOWN...DOYLESTOWN...MEDIA 1121 AM EDT SAT JUL 22 2006 ...STRONG TO SEVERE THUNDERSTORMS POSSIBLE THROUGH TONIGHT WITH MAYBE SOME ISOLATED TORNADOES... A SECOND ROUND OF STRONG TO SEVERE THUNDERSTORMS ALONG WITH MORE HEAVY RAIN IS EXPECTED THIS AFTERNOON AND TONIGHT AS A LOW PRESSURE SYSTEM DEVELOPS ON AN APPROACHING COLD FRONT. AS THE DAY CONTINUES A STRONG LOW LEVEL JET IS EXPECTED TO CROSS ACROSS OUR AREA. THIS WILL NOT ONLY HELP THE HEAVY RAIN CHANCES BUT INCREASE THE SHEAR...OR CHANGE OF WINDS WITH HEIGHT...IN THIS AIR MASS. THIS SHEAR COULD LEAD TO SUPERCELL TYPE THUNDERSTORMS AND POSSIBLY ISOLATED TORNADOES. AT THIS TIME MOST OF OUR REGION IS VULNERABLE TO POSSIBLE SEVERE THUNDERSTORMS AND ISOLATED TORNADOES. THE CONFLUENCE OF EVENTS WOULD FAVOR THE THREAT REACHING ITS PEAK DURING THE SECOND HALF OF THE AFTERNOON AND FIRST HALF OF THE EVENING. THE ONLY LOCATIONS THAT MIGHT HAVE A LOWER RISK WILL BE ALONG THE ATLANTIC COAST AS SOUTH TO SOUTHEAST WINDS WILL REDUCE THE INSTABILITY. THE AMOUNT OF SUNSHINE OVER OUR AREA THIS AFTERNOON...AND PLACES TO THE SOUTH...WILL HAVE A STRONG BEARING ON HOW UNSTABLE OUR AIR MASS BECOMES AND HOW MUCH EASIER IT WOULD BECOME FOR SUPERCELL TYPE THUNDERSTORMS TO DEVELOP. WE HOPE THAT THE PRESENT CLOUDS AND SCATTERED THUNDERSTORMS OVER AND SOUTHWEST OF OUR AREA WILL LIMIT THE AMOUNT OF SUN. THIS IS ONE REASON THE STORM PREDICTION CENTER HAS PLACED THE REGION IN A SLIGHT AND NOT A MODERATE OR HIGH RISK FOR SEVERE THUNDERSTORMS AND POSSIBLE TORNADOES. PLEASE LISTEN FOR FURTHER UPDATES AS THE DAY CONTINUES. WE WILL ALSO ISSUE A PUBLIC INFORMATION STATEMENT LISTING SOME TORNADO SAFETY RULES. THIS IS ONE OF THE RARE DAYS IN OUR AREA THAT YOU SHOULD LET THE WEATHER DICTATE YOUR ACTIONS AND NOT THE OPPOSITE. IF YOU HAVE PLANS THAT TAKE YOU OUTDOORS...PLEASE SEEK SHELTER INDOORS IN A PERMANENT BUILDING AT THE FIRST SIGN OF THREATENING WEATHER OR IF A WARNING IS ISSUED FOR YOUR AREA. MARINERS SHOULD GIVE THEMSELVES MORE THAN AMPLE TIME TO REACH SAFE HARBOR.
