Temperatures reached 70 last Thursday for the first time since last November. If you liked that tease of spring warmth, get ready for this week, as it offers a spread of May-like warmth, along with spring-like thunderstorms possible on Tuesday and again Friday.
Eighty-degree weather has and does occur in March from time to time, most recently in 2007 — just a couple of days before the "Ice of March," also known as the St. Patrick's Day sleet storm. You don't need to be Shakespeare to wax poetic about how cruel and fickle March weather can be and all it takes is a rogue cool front sneaking in off the Atlantic to turn shorts-weather into dreary drizzle and clouds. While the coming week features significant warmth, it may be muted this weekend a bit with the presence of a cool front that pushes through on Friday night into Saturday with shower and thunderstorm chances. Some of the computer models show dreariness extending into Sunday.
However, between now and then, the week ahead should feature some rather nice weather on the whole with one other exception. Monday night and Tuesday features a disturbance pushing through the region with showers and thunderstorms in two rounds — the first on Monday night, the second on Tuesday afternoon. The second round would probably bring the better chances of thunderstorms to the region.
High temperatures could be their highest this week on Tuesday — potentially reaching or breeching 75 degrees in the suburbs. Wednesday and Thursday may be a touch less warm than Tuesday but temps should hit or flirt with 70 either day with mostly sunny skies.
I alluded to the point about how it can hit 80 around here in March; the record highs for this time of the year in Philly are in the 80s from warm waves that hit the region in 1990. Even though it will be about 15 to 20 degrees warmer than average on many days this week, record heat is unlikely. You can still fire up the grill for most of the days this week. Enjoy the warmth.
