Slow Moving Front = Afternoon Showers & Thunderstorms

5pm climate report on Tuesday
5pm climate report on Tuesday

I told you a few days ago that Tuesday would be the hottest day and it sure lived up to its expectation! After a low of just 76 at Philly International in the morning we reached a high of 95 by 1pm before the cumulus clouds bubbled up; shortly thereafter some showers and thunderstorms began to pop up in the afternoon as the "appetizer" for a line of severe storms just after sunset. The rainfall will be reflected by the overnight final climate report, but as of 11pm 0.17" was recorded at the ASOS station along the tarmac. Although Philly scathed the worst rain there was much heavier downpours toward the east in New Jersey.

A cold front is trying to progress eastward, but will take its sweet time in doing so; the threat of showers and thunderstorms will continue overnight and  into Wednesday

Overnight there will be scattered showers and thunderstorms along with some fog; lows will be in the lower 70s. Wednesday will feature some morning clouds and fog, but then we'll break out in some sunshine....

But don't be fooled! We're still going to be into a humid and unstable air mass so the clouds will bubble up in the early afternoon with the thunderstorms starting to billow up shortly thereafter. Highs will be right around 90 with a continued southwesterly wind around 10mph. The front finally pushes eastward overnight into Thursday morning and that means we'll have high pressure on top of us along with drier air. Highs on Thursday will be in the lower 80s with a northerly wind bringing in that cool Canada air(why do people always say "Canadian" for? It doesn't have citizenship!).

Highs on Friday will be in the same ballpark, but in the afternoon we'll have some clouds billow up as a short wave will pass by to the south; I feel that showers and thunderstorms shall stay to our south across the Mason-Dixon Line, but if one did pop up at least I warned you. It's gone by the early morning hours on Saturday as high pressure is still on top of us, but with a more easterly wind. Highs will be in the lower to middle 80s(the further inland you go the better chance of getting to 83, 84 while the shore will be in 78, 79, 80 with the onshore wind).

High pressure then pushes further offshore and we get into a more southerly flow for Sunday; this also means that the humidity will creep back up as we approach 90 degrees. There will be a weak cold front in the late afternoon that may spark off some showers and thunderstorms. Behind that front it's just as warm(if not warmer) with highs in the lower 90s as a more potent cold front will push through in the late afternoon; this means another shot at showers and thunderstorms that will linger through the overnight and into Tuesday.

But let's not get ahead of ourselves now; after Wednesday let's enjoy the rest of THIS week before we talk about the next one. Remember that you can always follow my 7-day forecast(any time) at
