Warmest day in six months

These are not the best of days for tree-pollen sufferers, but most people around here have been waiting for something like this.

After a chilly March that lapped into Easter week, spring asserted itself today, and at 4:01 p.m. the temperature reached 78 at Philadelphia International Airport.

Although that is way shy of the record for the date -- 90, in 1929 -- that's the highest official reading in Philadelphia since the 78 of Oct. 6. Normal is 61; 78 is normal for a May 31.

Tomorrow should be a few degrees warmer, and temperatures are heading into the June-like 80s on Wednesday.

If you're heading to the game, the temperatures should remain in the 60s throughout, and this might be an opportunity for Ryan Howard to end his homerun drought.

Warm air tends to add buoyancy to the atmosphere, and tonight a gentle breeze will be blowing from the south, or straight out to center.

Ballparks typically are oriented that way -- homeplate, south; centerfield, north -- so that the sun won't shine in players' eyes during day games.

Tonight, they won't have the wind in their faces either.
