In case you place any faith in the prognostications of the 'meteorological priesthood', the rain is supposed to clear out of the Boston area around 8 PM tonight. Of course, these are the same people whose forecasts resulted in us routinely shoveling 14 inches of "partly cloudy" off our driveways this past winter. In any event, the pelting rain around the area right now (11 AM) does not look like it's going to dissipate any time soon. As the radar image shows, there's even more rain to come behind the current batch. So, if you go to Fenway, be prepared to be gouged for lots of beer and hot dogs during the likely long rain delay. Fair—or actually, partly cloudy—warning.
