we are looking now with winds of 40 miles per hour. as you know we had storms much stronger for the wind category. this has a lot of rain with it. a big wet sponge now moving the way across heading to central parts of mexico. highs today around here. look at this. 90 in lawrence. only 71 in nantucket. big temperature spreads going on today. tomorrow, looks like more and more of us will be close to the 90-degree mark. right now, 71. winds out of the south. dewpoints are manageable. om and that means it is going to feel uncomfortable. tomorrow, the sticky category. saturday up here in the oppressive rain. that sets up for the thunderstorms. then behind look at what happens. the dewpoints drop off. sunday, look spectacular out there. we got the clear skies now. out here to the west, a cold front. it is where the thunderstorms are triggering off. out ahead of it. it gets muggy. behind it, it is nice and dry. the thunderstorms will continue

they got a long way to go before they get here. tonight, clear. patchy fog. tomorrow, sunny, maybe just slightly more humid than it was today. 86-90. then looking down the road tomorrow, where we are seeing temperatures getting close to 90-degree mark. all right. talking the thunderstorms on saturday. hot and muggy weather moves in here tomorrow night. a cold front from the west. around 2:00 is when the things start to fire up. cool, less humid air. let's give the hour by hour of what is going to happen. 10:00 on saturday night. the clouds are rolling in here. then we start to see a live thunderstorms forming out here around lunchtime. looks like it is moving to the boston area around 3:00 and continue to march toward cape probably arriving around 5:00 or

that would give us a couple of hours. give you the idea during the time you want to be outside. that is why it makes it most dangerous. we're outside. we have thunderstorms going the lightning potential out there. we have highlights on saturday in red. a high impact weather dare. look for temperatures to be warm into the 80's. 80 would be the high. notice on sunday. humidity drops off. only 80 deg with the high of 82 degrees then, humidity manageable on sunday. on monday, and most of tuesday is fine. ed, maria. ed: you may have notice. our friend and colleague and family member bob halloran has been off the air since reporting from training camp. mob was headed to see a doctor for migraine. it turns out that bob had brain aneurysm. maria: after successful
