Like A Broken Record !

Hot and Humid conditions, followed by Pleasant and much Cooler weather towards the weekend.

We continue to be stuck in a repetitive pattern over the past month or so. The flow continues to be quite progressive for this time of the year, and the Northern Branch or Canadian Jet, continues to nose itself into the Great Lakes and Northeastern US. In between this flow, some ridging is bringing on the Heat and Humidity once again. The pattern relaxes itself briefly with the heat, then much cooler air follows, for a more prolonged period of time. We have yet to see our first heat wave, but this week may be our first Mini Heat wave here in many parts of the Delaware Valley.

This however will be short lived and followed by Cooler, Less Humid Canadian Air, Later this week into early next week. Temperatures will be in the low 90's for much of the Delaware Valley, for both Wednesday and Thursday. A strong Cold front will slowly work it's way, south and eastward, from the Great Lakes on Thursday. This will be setting the atmosphere up for potentially, Strong to Severe Thunderstorms, later Thursday into Thursday Night. With plenty of heat and humidity in place, ahead of this front along with it's slow movement, any thunderstorms may contain very heavy rain, so this may be a concern in some areas, where these storms occur. This front should cross the Area Friday morning, but it's slow movement may cause Mostly Cloudy skies with some showers for Friday. Temperatures will really cool off considerably, with highs near 80 and lowering humidity levels.

A very strong and large Canadian High, will build in over the weekend bringing pleasant weather. Expect P.Sunny days and Clear cool nights as this High builds in over the weekend. Temperatures will be near 80 both Saturday and Sunday, with lows of 55 to 60.

I'll have more for next week, as we approach the weekend, but many signs are pointing to a continued pleasant start of the week, with highs near 80 and lows near 60. Not bad for this time of the year.
