As we head into the weekend, our upper level pattern will be changing. We’ve been stuck with the northern jet taking a dip into the eastern U.S., helping keep temperature cool.

However, that upper level jet will finally flatten out, allowing the warmth from out west finally to migrate eastward.

It’s been a while since some areas have seen their last 70 or 80 degree day – last year in places! There’s a good chance that could change, though.

Boston

We’ll start out in Boston, MA – yes, the same Boston that saw 110.6″ of snow this past winter, making it their snowiest on record. They will see their first 70s of the year as we head into Monday and Tuesday, before a front swings in bringing rain and cooler conditions.

Philly

Philadelphia, PA, looks to top 80 next week as the warm front passes though, and these warmer temperatures look to stick around through midweek.

Chicago

It’s a cool start to the NFL Draft in Chicago, IL, today – however, by the time we get to the last rounds on Saturday, temps will warm back into the 70s. We could even have a shot at 80 Sunday and Monday before a cool front moves through.

Minneapolis

We’ve already hit 80 once this year in Minneapolis, MN – back on April 1 when the high hit 84. A couple more days of 80 degree weather is possible this weekend before a cool front moves though Sunday, dropping temperatures back into the 70s.

Phoenix

Back out west, however, we could see temperatures into the 100s in the Phoenix area over the next few days. Good news? Cooler weather looks to prevail heading into the second half of the weekend.

Vegas

And while there will be a hot fight going on Saturday inside the MGM Grand between Pacquaio and Mayweather, temperatures outside will be just as warm, getting into the upper 90s before temperatures start to cool starting Sunday.

Kentucky Derby

Looking like great weather for the Kentucky Derby, with temps in the low 70s around the time the horses run around the 1 1/4 mile track at Churchill Downs under a mix of clouds and sun!

Have a great Thursday… and just remember, tomorrow…
