NO CHANGES TO THE PUBLIC SECTION. && .SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/... VERY ATYPICAL OF EARLY JULY AT THIS LATITUDE...A BONE DRY AIR MASS OF CANADIAN ORIGIN WILL DOMINATE THROUGH FRIDAY. MODEL TIME HEIGHT CROSS SECTIONS INDICATE RELATIVE HUMIDITY BELOW 10 PERCENT THROUGH A DEEP LAYER OF THE COLUMN THROUGH FRIDAY EVENING. SURFACE RH WILL FALL INTO THE LOWER 30S EACH AFTERNOON...WHICH WILL BE VERY REFRESHING COMPARED TO THE 100 PLUS HEAT INDICES LAST WEEK. THE DRY AIR WILL LEAD TO QUITE A LARGE DIURNAL TEMP RANGE FOR THIS TIME OF YEAR...LIKELY AROUND 30 DEGREES. MOS GUIDANCE LOWS IN THE MID TO UPPER 50S LOOK GOOD FOR EACH OF THE NEXT COUPLE NIGHTS. IF WINDS WERE NOT SO BRISK IN THE BOUNDARY LAYER...FORECAST LOWS WOULD BE ADJUSTED LOWER THAN MOS. DAYTIME HIGHS UNDER FULL SUN SHOULD AVERAGE MOSTLY IN THE MID 80S THROUGH FRIDAY. THE RATHER STRONG SURFACE HIGH WILL SLIDE SOUTHEAST TO THE APPALACHIANS BY SATURDAY. WINDS WILL BECOME SOUTHEAST AND THEN SOUTH OVER THE WEEKEND...BRINGING A RETURN TO HEAT AND HUMIDITY MORE TYPICAL FOR THIS TIME OF YEAR. THOUGH TEMPS WILL LIKELY CLIMB BACK INTO THE LOWER 90S OVER THE WEEKEND...DEW POINTS ARE FORECAST TO BE QUITE TOLERABLE COMPARED TO MOST OF JUNE. DEW POINTS IN THE MIDDLE 60S TO PERHAPS UPPER 60S SHOULD KEEP HEAT INDICES BELOW THE CENTURY MARK. A RATHER LARGE DIFFERENCE STARTS TO APPEAR AMONG THE MODELS EARLY NEXT WEEK. THE 00Z ECMWF CONTINUES TO BE STRONGER THAN THE GFS REGARDING THE 500 MB RIDGE OVER THE OHIO VALLEY...AND THEREFORE HOTTER. FORECAST TEMPS FOR MONDAY ARE VERY CLOSE TO HPC GUIDANCE...WHICH MEANS A FEW DEGREES HIGHER THAN GFS MOS. GIVEN THE SLIGHT PREFERENCE FOR THE ECMWF...WILL HOLD OFF ON ANY POPS THROUGH MONDAY. .LONG TERM /TUESDAY THROUGH WEDNESDAY/... MODELS IN BETTER AGREEMENT IN THE LATTER PERIODS OF THE FORECAST. NEXT TUESDAY INTO TUESDAY NIGHT EARLIER GFS MODEL RUNS BROKE DOWN THE UPPER RIDGE THUS ALLOWING MOISTURE/PRECIP TO SNEAK BACK INTO CWA...BUT THE ECMWF HUNG ON TO THE RIDGE KEEPING OUR REGION DRY. LATEST GFS NOW KEEPING THE MOISTURE AXIS ALONG THE WESTERN AND NORTHWESTERN FRINGES OF OUR CWA FOR THOSE PERIODS SO WENT WITH SCHC POPS THERE. BOTH GFS AND ECMWF MOVE THE MOISTURE AXIS SLIGHTLY WESTWARD ON WEDNESDAY...SO WILL KEEP IT DRY. MODELS INDICATE A POSSIBLE FROPA WEDNESDAY NIGHT INTO THURSDAY...BUT DUE TO LACK OF MOISTURE...DONT EXPECT MUCH OF ANYTHING IN THE WAY OF POPS...SO KEPT IT DRY. && .AVIATION...
