Below Average Temperatures For The Remainder Of The Week

Climate report for Wednesday
Climate report for Wednesday
Scott Derek

Wednesday was a tale of two days; after heavy rain and thunderstorms overnight we got rid of the rain by sunrise and the clouds by late morning to end the day on a sunny note. After a low of 69 and a trace of rain recorded at Philadelphia International Airport we reached a high of just after 3pm. The further south and east you went however there were flooding rains late last night into the morning with anywhere between 3-7" of rain that fell from training storms. There were a few isolated showers and thunderstorms in the afternoon, but they were confined to northern NJ and across Long Island where Islip NY saw a 24-hour total of over 13" !

The frontal boundary is offshore and cool Canada air will take over our weather for the remainder of the work week

Overnight it will be a complete 180 of the night before with a mostly clear sky and lows ranging from the upper 50s in the suburbs to the lower 60s in Center City; Thursday will feature sunshine mixed with some fair weather cumulus clouds that will bubble up in the afternoon once we reach our convective temperature(the estimated temperature that the surface must warm to in order for clouds to develop). Highs will be right around 80 degrees with a west-northwest wind between 10-15mph early, but subsiding to between 5-10mph in the afternoon.

After an overnight low Thursday in the upper 50s we will be in the upper 70s for Friday with sunshine and those fair weather cumulus clouds will pop back up in the afternoon once again as we'll have that continued west-northwesterly flow(which is a cool and dry flow from Canada). Saturday we'll get into a more west-southwesterly flow so highs will be into the lower 80s under sunshine, but then some high clouds will filter the sky from a cold front approaching from the Great Lakes.

This means that overnight Saturday will be overcast while Sunday morning will feature some showers as the frontal boundary pushes southward; we'll try to clear out by the late afternoon, but it may be a bit far fetched. Regardless, highs will be in the middle 80s. The frontal boundary will be just to our south so on Monday we'll have sunshine with a north-northwesterly flow as highs will be in the lower 80s, but come Tuesday we'll get into the more humid southerly flow. Highs will be in the upper 80s with increasing clouds in the afternoon ahead of a cold front that will be progressing to the east; the problem is after showers and thunderstorms on Wednesday we won't cool off again. Instead we'll stay in the middle and upper 80s with that humid air mass still in place. So much for a continued Fall feel.....but if you are a fan of that summer heat your wishes have come true!
