all right. coming up on "morning joe," jeffrey sachs will be joining us. interesting. him speaking before i believe some bankers and he was a little blunt. eugene robinson will be here along with rana foroohar. kal penn will discuss his exciting new show. and a new look at america's 16th president and why the historic debates with stephen douglass still matter in today's politics. but first, here's bill karins with a check on the forecast. we'll improve things all the way up through new england. yesterday was a cloudy damp day with on and off rain, today's a little bit better, then we have a great stretch of weather right into the upcoming weekend. first things first, temperatures are kind of cool in the big i-95 corridor, upper 40s to low 50s. light jacket needed, still a chance of rain showers today from washington, d.c., coastal maryland, delaware, not so bad, though, in new england, we should be mostly dry from hartford to boston.
