It's been my experience that the National Weather Service is typically the most reliable with forecasts. They just updated things for the worse. As of this posting they officially list Monday's high as 76, up about 10 degrees from earlier, but there was also this dire possibility in their detailed forecast discussion:
MONDAY AND TUESDAY...THERE IS STILL SOME UNCERTAINTY HERE THOUGH THE
MODELS HAVE COME INTO MORE OF AN AGREEMENT ON THIS TIMEFRAME. AS
STATED ABOVE...BOTH MODELS BRING THE COLD FRONT ONLY AS FAR SOUTH AS
NORTHERN NEW ENGLAND. THIS KEEPS SOUTHERN NEW ENGLAND ON THE WARM
SIDE OF THE FRONT WITH THE WARMING TREND SEEN OVER THE WEEKEND
CONTINUING. THE LATEST ECMWF RUN INDICATES TEMPERATURES COULD BE
WELL INTO THE UPPER 80S MONDAY...WHICH WOULD SET RECORDS AT BOSTON
/84 IN 2003/ AND WORCESTER /84 IN 2002/. IT WOULD NEAR OR PERHAPS
TIE RECORDS IN PROVIDENCE /88 IN 2003/ AND HARTFORD /90 IN 2002/.
TUESDAYS TEMPERATURES SHOULD BE VERY CLOSE TO MONDAYS...THOUGH THERE
IS THE POSSIBILITY FOR A FEW SHOWERS TUESDAY. WILL BE KEEPING A
CLOSE EYE ON THIS FORECAST THROUGH THE WEEKEND.
Well into the upper 80s possible? I know I grew up in Florida and all, but that's %&#$ing hot and to say it wouldn't affect me significantly is flat out bull. No point in putting sugar on a turd, it'll still taste like crap.
I'm considering using Boston as a fun run if it does indeed get that hot and maybe taking my faster legs to Sugarloaf and let loose there. I worked really hard to try and get a sub-3 and don't want to waste it.
