Sunday was a mild day with sunshine mixed with fair weather cumulus clouds in the afternoon; after a seasonably cool morning of 52 at Philly International Airport we reached a high of 82 in the afternoon. So essentially we ran five degrees below average this morning, but then ran over five degrees above average in the afternoon(it averages out). Overnight some higher clouds with a warm front will keep us milder with lows in the lower 60s, but middle 50s north and west with lingering cloud cover for the beginning of Memorial Day itself.
Speaking of Memorial Day it will stay dry so parades should be fine, but as previously mentioned the clouds will linger a bit in the morning to the north as that warm front progresses through the region. Highs will range from the lower 80s north to the middle and upper 80s south with sunshine as well as the humidity creeping up as well(you’ll start to feel it).
Come Tuesday everyone is under the influence of a southern ridge(500-millibar maximum heights situated across the Southeastern United States). That southerly flow will also bring in more humidity as well. Highs will be in the upper 80s with isolated showers/t-storms in the afternoon. This will also be the case for Wednesday and Thursday as well(a cold front will be pushing through Thursday evening, albeit not really that impressive).
Friday will be around 80 with a more potent cold front providing showers and thunderstorms in the afternoon, but behind it it’s back into the middle and upper 80s for the weekend with dry conditions Saturday, but near 90 & humid on Sunday with even a thunderstorm chance.
