Philly is bracing for a rollercoaster of weather this week, with the National Weather Service in Mount Holly indicating a sunny sky today followed by a swing of showers and possibly thunderstorms by midweek. Temperatures are set to dance around the mid-to-high 60s, slipping into a cool mid-50s by Thursday. The City of Brotherly Love saw a calm and chilly start this morning, with the mercury dropping to just above the freezing mark, triggering a Frost Advisory in effect until 9 AM EDT, as NWS says.

After shedding the frost, Philly residents gear up for increased cloudiness tonight, but the real headline is the elevated fire danger posed by a potent blend of low humidity and gusty winds this afternoon, while the NWS warns "any dry grasses and tree litter that ignite will have the potential to spread quickly." Philly, we've got a low chance of widespread hazardous weather through tonight, but there's a minor risk of coastal flooding rolling into Tuesday, so best keep an eye on that waterfront property.

But the sun's not hiding for long, with the forecast promising plenty of rays right through to the weekend, and by Sunday, Philly's set to sizzle with highs approaching 80 degrees, the NWS previews. Sure, there's some cloud play forecast for the weekend, but Monday looks to serve up a slice of summer, with the high tipping into the low 80s. For your sprouts and blooms, tonight's increase in cloud cover means that your plants are safe from Jack Frost, for now, Philadelphia can breathe out after holding its breath against the frost advisory earlier.

And if there's action in the skies, the NWS invites weather enthusiasts to join in the conversation, stating "Weather spotters are encouraged to report significant weather conditions according to standard operating procedures." So, whether you love it sunny, cloudy, or stormy, Philly's got it all in the forecast, just remember to toss a jacket over those tender garden greens tonight and keep the hose handy in the afternoon, you never know when you'll need to fight off a fiery surprise.
