The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jul 19, 1:36 PM EST, 1 hour 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 236 PM EDT THU JUL 19 2012 .SYNOPSIS... A LOW PRESSURE SYSTEM WILL TRACK SLOWLY EASTWARD ACROSS THE UPPER OHIO VALLEY REGION THROUGH FRIDAY NIGHT...BRINGING SHOWERS AND THUNDERSTORMS. && .NEAR TERM /THROUGH FRIDAY/... AREAS OF CONVECTION CONTINUE TO BUILD FROM EAST CENTRAL OHIO SOUTHWEST INTO SOUTHERN OHIO THIS AFTERNOON AS IR SATELLITE IMAGERY SHOWS COOLING TOPS. PLAN TO KEEP LIKELY POPS FOR SHOWERS AND THUNDERSTORMS WITH HEAVY DOWNPOURS FOR ALL ZONES THROUGH TONIGHT AS PW VALUES REMAIN BETWEEN 1.75 TO 2.00 INCHES. LATEST MODEL GUIDANCE SEEMS TO BE CONSISTENT WITH PREVIOUS RUNS WITH TIMING OF SHORT WAVE TROUGH AND ASSOCIATED SURFACE WAVE... MOVING SLOWLY SOUTHEAST ACROSS THE FORECAST AREA THROUGH LATE FRIDAY. NO FLOOD WATCHES ARE PLANNED FOR THE NEAR TERM AS CURRENT MOVEMENT OF STORMS APPEARS TO BE FAST ENOUGH TO PRECLUDE LONG DURATION HEAVY RAIN. WILL NEED TO MONITOR RAIN AMOUNTS CLOSELY THOUGH...ESPECIALLY ACROSS OUR SOUTHERN ZONES IF ADDITIONAL CONVECTIVE COMPLEXES TRACK ACROSS EAST CENTRAL OH AND NORTHERN WV LATER TONIGHT AND FRIDAY. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... THE SYSTEM IS PROGGED TO MAKE ONLY SLOW EASTWARD PROGRESS...WITH THE SURFACE LOW REACHING EASTERN VA SATURDAY MORNING AND THE UPPER TROUGH AXIS STILL STRETCHED ACROSS EASTERN NY INTO NORTHERN WV. FOR THE UPDATED FORECAST...WILL KEEP LIKELY POPS OVER THE EASTERN HALF OF THE FORECAST AREA AND CHANCE OVER WESTERN PORTIONS FRIDAY NIGHT. POPS FOR SATURDAY WILL RANGE FROM AROUND 40 PERCENT ALONG THE RIDGES TO AROUND 20 PERCENT ALONG THE PA/OH BORDER...AND LESS THAN 15 PERCENT FAR WEST. EXPECT SOMEWHAT DRIER CONDITIONS FOR THE LATTER HALF OF THE WEEKEND...WITH THE ASSUMPTION THAT THE MOISTURE ASSOCIATED WITH THE EAST COAST LOW WILL CONTINUE TO CREEP EAST OF THE FORECAST AREA. WEAK SURFACE RIDGING SHOULD PROVIDE ENOUGH BREAKS IN CLOUD COVER ON SUNDAY TO ALLOW TEMPERATURES TO RISE WELL INTO THE 80S MOST LOCATIONS...EXCEPT FOR UPPER 70S ALONG THE RIDGES. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... HIGH PRESSURE WILL BRING GENERALLY DRY WEATHER FOR SUNDAY NIGHT INTO MONDAY. A COLD FRONT WILL PUSH ACROSS THE DISTRICT FOR MONDAY INTO TUESDAY BRINGING SHOWERS AND SCATTERED THUNDERSTORMS. HIGH PRESSURE WILL BRING DRY WEATHER FOR WEDNESDAY INTO THURSDAY. SOME SHOWERS ARE POSSIBLE LATE THURSDAY AHEAD OF AN APPROACHING COLD FRONT. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... SHOWERS AND SCATTERED THUNDERSTORMS WILL PUSH ACROSS THE DISTRICT THROUGH THIS EVENING AS A COLD FRONT SAGS ACROSS THE DISTRICT. A WAVE ALONG THE FRONT WILL BRING RAIN FOR FRIDAY INTO FRIDAY AFTERNOON. SOME FLIGHT RESTRICTIONS ARE POSSIBLE THROUGH FRIDAY MAINLY IN THE SHOWERS AND THUNDERSTORMS. SOME FOG AND STRATUS IS POSSIBLE DURING THE EARLY MORNING HOURS OF FRIDAY. OUTLOOK...SATURDAY THROUGH TUESDAY... GENERAL VFR CONDITIONS FOR SATURDAY...SUNDAY AND MONDAY. A COLD FRONT MAY BRING SOME RESTRICTIONS MONDAY NIGHT INTO TUESDAY. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
