Area Forecast Discussion National Weather Service State College PA Issued by National Weather Service Binghamton NY 337 PM EDT Mon Jul 6 2026 .WHAT HAS CHANGED... * THE FLOOD WATCH HAS BEEN EXPANDED IN AREA TO INCLUDE THE NORTHERN TIER OF CENTRAL PA AND EXTENDED IN TIME THROUGH 2 AM TONIGHT. && .KEY MESSAGES... 1) LOCALIZED FLASH AND URBAN FLOODING IMPACTS ARE POSSIBLE AGAIN THIS AFTERNOON AND EVENING && .DISCUSSION... KEY MESSAGE 1: LOCALIZED FLASH AND URBAN FLOODING IMPACTS ARE POSSIBLE AGAIN THIS AFTERNOON AND EVENING WAVES OF LOW PRESSURE MOVING ALONG A STATIONARY FRONTAL ZONE AND INTERACTING WITH A FAVORABLE THERMODYNAMIC ENVIRONMENT WILL CONTINUE TO PROMOTE INITIATION OF SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON THROUGH THE FIRST HALF OF TONIGHT. THUNDERSTORMS WILL BE CAPABLE OF HIGHLY EFFICIENT RAINFALL RATES WITH REPEAT/TRAINING POTENTIAL. THE GREATEST RISK FOR FLASH FLOODING HAS SHIFTED FROM THE EASTERN INTO THE WEST/SOUTHWEST PORTION OF THE FORECAST AREA (BASED ON THE HREF AND REFS MODEL OUTPUT) WHERE FFGS ARE LOWER AND TERRAIN INFLUENCES ARE MORE IN-PLAY. HOWEVER, CONVECTION IS ALSO FIRING ALONG ZONES OF CONVERGENCE IN THE NORTHERN TIER, SO WE HAVE EXPANDED THE WATCH TO INCLUDE THAT AREA. WITH CAMS SHOWING THE POTENTIAL FOR HEAVY RAIN THROUGH MIDNIGHT, WE HAVE EXTENDED THE END TIME OF THE WATCH TO 06Z TUE. THE SEVERE STORM THREAT ALSO DOES NOT APPEAR TO BE AS ROBUST AS IN PRIOR DAYS (54 SVR+TOR WARNINGS IN THE PAST 3 DAYS). THIS IS REFLECTED IN MOST OF THE AREA IN A GENERAL OR NON-SEVERE TSTM OUTLOOK AND ONLY LEVEL 1/5 MRGL RISK COVERING THE SOUTHWEST THIRD OF THE CWA WHERE HIGHER CAPE AND STEEPER LAPSE RATES WILL BE MAXIMIZED. THE PATTERN FOR THE REST OF THE WEEK CAN BE SUMMARIZED MORE OR LESS BY TYPICAL EARLY JULY UNSETTLED/HUMID SUMMERTIME CONDITIONS WITH A LOW PROBABILITY OF SIGNIFICANT HAZARDOUS WEATHER. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... WITH PERSISTENT EASTERLY FLOW ACROSS THE REGION, MVFR TO IFR CEILINGS ARE LIKELY AT MOST TAF SITES, THOUGH JST AND AOO LIKELY SEE A PERIOD OF VFR CEILINGS THIS AFTERNOON. SHOWERS AND THUNDERSTORMS WILL DEVELOP DURING THE AFTERNOON, BUT INSTABILITY WILL BE MORE LIMITED THAN IT HAS BEEN THE PAST FEW DAYS. SHOWERS AND THUNDERSTORMS WILL PRODUCE VERY HEAVY RAINFALL, LEADING TO REDUCED VISIBILITY AS THEY MOVE OVER ANY AIRFIELDS. ANOTHER NIGHT OF LOW CLOUDS AND FOG APPEARS LIKELY FOR MONDAY NIGHT BEHIND THESE SHOWERS AND STORMS. Outlook... TUE...RESTRICTIONS POSSIBLE IN A.M. FOG AND P.M. T-STORMS.
