Of note we have not had a 90+ day in May since May 3, 2018. In that year we ended with 4 days above 90 that summer. The last time we had earlier 90+ temps (April/May) was on April 26 and 27, 2009. In that summer we never again saw a 90+ day as those 2 were the only times we were able to crack 90 that year and 1 day was 89.5. Before that our last 90 in May was on May 4, 2001.

Most of the heavy storms passed through far NW Chester County and into Berks County. However, with the frontal passage temps have fallen off pretty quickly by about 10 degrees in the past hour. The current temperature here in East Nantmeal is 62.3 down from 73.1 about 1 hour ago. Rainfall at least here in East Nantmeal has been light with only 0.07" of rain so far today. Should be a beautiful couple of days on tap both Tuesday and Wednesday with temps a little cooler than normal in the upper 60's to low 70's and lots of sunshine! A very brief warm up to above normal temps by Friday/Saturday with out 1st possible 80 degree readings across the County by that time. However, quickly back to slightly below normal temps again by the start of the new work week as we head toward Memorial Day weekend.

Unfortunately my Tempest down the shore in Sea Isle is again not working. Fortunately, Tempest is now sending me my 3rd unit since December's install. The problem is I need to hire a handyman with a 45 foot ladder to get up on the roof to replace each time this happens....this is getting to be an expensive hobby! Install is scheduled for Thursday morning. That said the one on my roof in East Nantmeal has been perfect for well over 1 year. Anyone else on a 3rd unit at their location??

UHI contamination remains a real problem and will only get worse as detailed below for some rural suburban sites vs. the PHL Airport...but at least we will continue to see our local weather folks continue to show plenty more 90+ days and heat waves for Philly at the official PHL station then we have ever seen before! As we are seeing a trend to less 90+ days outside of the UHI.....but of course non-stop increases at PHL

Coldest start to the year in the USA since 2014....is the colder phase starting earlier than we think?
