DRY CANADIAN HIGH PRESSURE WILL BUILD THROUGH NEW ENGLAND MIDWEEK...THEN OFF THE MID ATLANTIC COASTLINE THROUGH LATE NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... FOR THE REMAINDER OF THIS AFTERNOON...RADAR SHOWS NUMEROUS SHOWERS ACROSS THE REGION...WITH THE ONLY AREA CLEAR THE MID-COAST. STORMS HAVE PRODUCED NUMEROUS REPORTS OF SEVERE HAIL...FROM PENNY TO QUARTER SIZED. EXPECT THIS TO CONTINUE FOR THE NEXT COUPLE HOURS...WITH SEVERE STORMS ENDING FROM WEST TO EAST AS DRIER AIR WORKS IN. AT 330 PM...THE STRONGEST THUNDERSTORMS SHOULD BE EAST OF CONCORD THROUGH THIS EVENING. EXPECT SEVERE THREAT IN NEW HAMPSHIRE TO LARGELY BE DONE BY 530 PM...WITH MAINE ENDING AROUND 700 PM.

MEDIUM RANGE MODELS CONTINUE TO TREND PERSISTENT UPPER TROUGH OVER NORTHEASTERN STATES NORTHEASTWARD AROUND MIDWEEK. THE DEGREE TO WHICH THE MODELS ALLOW RIDGING INTO THE REGION VARIES SIGNIFICANTLY. THE OPERATIONAL GFS CONTINUES TO BUILD A MASSIVE RIDGE ACROSS THE NORTHEASTERN STATES...PUSHING THE JET WELL INTO NORTHERN ONTARIO AND QUEBEC. THE ECMWF IS AT THE OTHER END OF THE SPECTRUM KEEPING THE UPPER TROUGH AXIS OVER OR JUST EAST OF MAINE THROUGH THE END OF THE COMING WEEK. HPC CONFIDENCE IN ANY ONE SOLUTION IS LOW.

BASED ON THE SPREAD OF SOLUTIONS...AND THE OBVIOUS UNCERTAINTY...WE WOULD BE HESITANT TO DEVIATE SIGNIFICANTLY FROM THE HPC/MOS GUIDANCE FOR BOTH TEMPERATURES AND POPS. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/...
