liquid gold. a chunk of dry air will keep us mostly blue today and we'll have a lot of sunshine. nice afternoon and then a front comes in. a southeast flow first priming the atmosphere here with showers on thursday.

then the front comes in. unfortunately the low associated with it goes up north and so that means it won't drive through here, so it will meander, stall out and that means rain chances going up significantly beginning friday. coverage about 50%. that continues into the upcoming weekend. so keep it in mind for outdoor activities. a lot of clouds when you have a front nearby, occasional showers especially through the afternoon. temperatures today approaching 80. nice and mild. close to normal for this time of year. overnight lows tomorrow morning in the 60s. should lose those 40s certainly up across citrus and hernando counties. highs tomorrow afternoon low to mid-80s. save for the coast. a sea breeze kicking in will keep you a little cooler, 70s. we'll hit about 80 this afternoon sunny and mild. hour by hour, 50s and low 60s. there it is by noon, 74.

upper 70s to around 80 degrees for -- there will be a few areas that will reach 81 or 82. otherwise looking pretty good. extended forecast, again we'll talk about rain chances back up tomorrow as we increase that moisture about 20% coverage. temperature around 82. overnight lows in the 60s. then friday that is when we really get into the rain chances up to about 50%. again, this continues into the upcoming weekend. saturday 81. temperatures in the low 70s at night. in the low 80s as well heading into sunday. rain chances 50%. as that front stalls and in fact i think it will be hanging out with us through early next week on monday with temperatures around 81. and then finally gets a push out of here so that by tuesday we'll be able to clear out, approaching 80 degrees with overnight lows a little cooler in the 60s.
